The question \"are prediction markets haram?\" is among the most frequently asked by Gulf readers, and among the most exposed to hasty answers: either a prohibition built on a mere outward resemblance to betting sites, or a marketing-grade permission with no evidence and no analysis. This article takes a third road: it lays out the fiqh analysis itself — the classical definition of maysir and its pillars, and the three grounds jurists examine in any financial contract (gharar, maysir and riba) — and then applies them to the actual mechanism by which event trading works at PolySouq: a shared parimutuel pool into which participants place their money, so that those who were right split the opposite pool pro-rata by their own share, with a 10% commission taken from the losing pool alone — meaning the platform holds no position in the market and there is no \"house\" profiting from your loss. Against that, we present the counter-arguments in full and in good faith. This article is not a fatwa; the question is one of serious ijtihad, and the final decision is yours after asking a qualified scholar — with the warning that the money involved is real and that losing your staked amount in full is a live possibility.
When a reader searches for the ruling on prediction markets, he usually collides with two opposing answers, and both are incomplete. The first issues a quick verdict of prohibition based on outward resemblance: "money is staked, the event's outcome is unknown, whoever is right takes and whoever is wrong loses — so it is maysir." The second is a marketing answer that says "this is trading, not betting" and then moves straight to the signup button, without ever explaining what makes one transaction trading and another gambling. The first abolishes the analysis; the second abolishes the honesty.
Fiqh does not work on labels; it works on the true nature of contracts. Calling a transaction "trading" does not lift it out of maysir if its reality is maysir — and the converse is equally true: an outward resemblance is not on its own enough to prove that two realities are one. That is why the serious road to an answer runs through three unavoidable stations: establishing the definition of maysir as it is formulated in the books of transactional fiqh; then establishing the grounds on which the prohibition is built; then examining the actual contractual mechanism of the product in question — not the impression of it.
This article is devoted to the second and third stations: the reasoning itself and the classical definitions, the side that introductory pieces rarely have room for. If you are looking for a short, direct treatment of the question, see our article Is prediction market trading halal?; and if your question is practical, about account arrangements and their requirements, see the Islamic account in prediction markets. The article in your hands complements those two rather than replacing them.
And we set down from the first line an explicit reservation we will not walk back anywhere below: what you are reading here is not a fatwa, and we are not a body authorised to issue one. This is a question of contemporary ijtihad in which serious disagreement exists among the people of knowledge. We present the arguments and the counter-arguments, and describe our own mechanism precisely, so that whoever is qualified to rule can build on it. The decision in the end is yours, after asking a qualified scholar and putting to him the detailed mechanism rather than the brand name.
Maysir, in its linguistic and historical origin, was a form of risk-taking known to the Arabs before Islam: portions of a slaughtered camel divided by drawn arrows, so that whoever's arrow came out gained and whoever's did not lost, with wealth moving purely on what the arrows produced. Then the Qur'anic text prohibited it, coupling that prohibition with mention of its effect in sowing enmity and hatred and turning people away from the remembrance of Allah. So the ruling in the fiqh tradition has two faces: one attached to the form of the contract and the transfer of wealth without consideration, and one attached to its effect on the soul and on society. Any serious analysis of any modern financial product is required to pass both tests, not one of them.
In the literature of transactional fiqh, the pillars of maysir are usually formulated as four interlocking elements: both parties putting up financial consideration; entitlement made contingent on something not certain to occur; one party's gain resting on the other's loss, such that the winner takes the loser's money without recognised counter-value; and the dominance of chance, such that skill or effort has no real bearing on the outcome. The whole is summed up under a broader principle: consuming wealth unjustly, meaning wealth moving without lawful consideration in the form of a good, a benefit, work, or the bearing of risk in something genuinely owned.
The value of keeping these pillars in view is that they block two errors at once. They block the first error, over-extension, which would make every financial risk into maysir — and if that were sound, buying shares, founding companies and buying goods before prices swing would all fall inside it. And they block the second error, over-narrowing, which would make changing the name or the technical interface enough to lift the ruling. The test is structural: are the pillars all realised in this particular transaction?
Notice what the table says honestly: the first two pillars are present beyond argument in event trading. The real discussion is confined entirely to the third and fourth. Whoever builds the answer on the first two alone has ended the discussion before it started, because those same two pillars are realised in a great many financial contracts nobody calls maysir.
When a modern financial contract is put to fiqh analysis, the examination normally runs over three principal grounds, plus one overarching principle. The first ground is riba, whose subject is a stipulated increase in loans and debts, or a defect in the exchange of ribawi assets. The second is gharar, whose subject is ignorance and uncertainty in the consideration or the subject matter. The third is maysir, whose subject is wealth moving on pure risk without consideration. And overarching them all is the prohibition of consuming wealth unjustly.
The single most common mistake in popular discussion is conflating gharar with maysir and treating them as one thing. They are distinct. Gharar is a description of knowability — how much you do not know about the consideration, its timing and its description — and a little of it is tolerated while a great deal leading to dispute is not. Maysir, by contrast, is a description of the structure by which ownership transfers — that one party's gain is built on another's loss with no counter-value. Gharar can exist without maysir, as it does in many exchange contracts carrying tolerable uncertainty; separating the two grounds is therefore a condition of any disciplined analysis.
So in the sections that follow we will examine each ground on its own, beginning with the one most easily settled — riba, which is absent structurally rather than by favour — then gharar, which requires detail and an explicit admission of where uncertainty genuinely sits, and then maysir, which is the real field of disagreement. Before that, if you are not familiar with how these markets operate, reading how prediction markets work will make the rest of the analysis clearer, because ruling on a mechanism presupposes understanding it first.
Riba, in its well-known classification, is of two kinds: riba of debts, the stipulated increase against deferment in a loan or a debt, and riba of exchange, the defect in trading ribawi assets with excess or with delay. Both kinds presuppose a lending relationship or an exchange of two monetary considerations with deferment or increase between them. That is the correct way into examining any platform: we do not ask "does it describe itself as riba-free?" but "does its structure contain a loan, or a priced deferment?"
In PolySouq's structure none of that exists, not even in hidden form: no lending between you and the platform in either direction; no interest computed on your balance; no time cost for keeping a position open however long the market runs; and no leverage and no margin — the very source from which interest-bearing financing arises on conventional trading platforms. You do not borrow to multiply your participation, and there is no "overnight fee" or "swap" deducted from you or added to you as nights pass. The platform pays you no yield on an idle balance and charges you nothing for holding it.
The commission deserves precise treatment, because it is so often confused with riba. PolySouq's commission is 10%, and it is taken from the losing pool alone — meaning it is deducted from profits actually generated, not from anyone's capital and not against deferment. It is therefore not an increase on a debt and not a price for time; it is consideration for operating and settling the market. Among the consequences of this structure: your staked amount is returned to you in full when you win, on top of your share of the profits, and the commission is zero in every case where no profits are generated at all. For the operational detail of deposits, withdrawals and fees see deposits, withdrawals and fees.
And in fairness of presentation, there is an adjacent detail we do not brush aside: settlement is in real USDC on the Polygon network, and contemporary scholars have written extensively on digital currencies and exchange as such — a question independent of ours here. Converting your local currency into USDC happens outside the platform and carries its own rulings for whoever researches it. What we establish in this section is confined to this: the structure of the contract itself contains no interest, no lending and no pricing of deferment.
Gharar is not forbidden absolutely — otherwise transactions as a whole would be impossible, since no contract is free of some measure of uncertainty. The settled distinction in this chapter is between minor gharar, which is overlooked, and excessive gharar, which leads to dispute and to consuming wealth unjustly; and between gharar in existence (does the consideration exist at all?) and gharar in description and amount (how much is it, and what is it like?). A further distinction is drawn between exchange contracts, in which knowability is treated strictly, and gratuitous or participatory contracts, which tolerate what others do not.
Let us apply that frankly to prediction markets. What is known at your entry is fully known: the amount you stake is set in dollars and you are the one who sets it; the settlement rules are published before entry; the source of the result is declared; the close and settlement times are declared; and the payout formula is published word for word: payout = staked amount × (1 + losing pool ÷ winning pool × 0.9). There is no uncertainty in the obligation you take on, and none in the rule by which your entitlement will be computed. You can read the settlement detail in how PolySouq settles markets transparently.
But honesty requires naming the uncertainty that genuinely exists: the payout ratio is not precisely known at the moment of entry, because the size of the two pools shifts for as long as the market is open. You know the formula and you do not know the final number. That is real gharar in the amount of the consideration; we neither deny it nor soften it. The argument advanced in reply is that what you acquire is not a fixed sum but a proportional share in a pool determined at close — a characterisation closer to participation ratios than to an unknown price. Anyone wanting to understand how ratios are read as probabilities should see reading prices and probabilities.
What remains is to weigh this gharar. Is it minor and tolerated, because the rule is known, the result is computed automatically and there is no room for dispute? Or is it excessive and voiding, because the counter-value is not fixed in amount at contracting? This is a matter of ijtihad, and we make no claim to settle it. What we commit to is putting the complete picture before whoever does exercise that judgement: the rule is known, the number is not.
If riba is absent and the question of gharar has been set out, the central question remains: where is the line between legitimate risk-taking and gambling? Four criteria recur in this discussion. (1) Is the transaction zero-sum, so that one party's gain is precisely another's loss with no added value? (2) Is the outcome pure chance, or do knowledge and analysis have a meaningful bearing on it? (3) Does the transaction transfer a pre-existing risk, or does it create a risk that did not exist except by the contract itself? (4) Is there a house with a structural edge that wins by design rather than by being right?
The first criterion — zero-sum — is the weakest of the four on inspection, because many lawful exchange contracts are zero-sum in a single moment: whoever sold a good before its price rose lost what the buyer gained, and so did whoever sold a share before it climbed, without anyone saying the sale was maysir. The second criterion — chance — is stronger, but it is graduated rather than binary: a market on the direction of a monetary policy decision, or on the path of the oil price after a producers' meeting, is subject to genuine analysis that can be done well and botched by the hasty, whereas a single sporting result leans more heavily on coincidence. Which is why a single undifferentiated ruling on "prediction markets" as a whole is hasty in both directions.
The fourth criterion is the most structurally decisive, and it is where the clearest difference sits between the house model and the pool model. In the house model there is a party that sets the prices, takes the other side of you, and engineers its margin so that it is the long-run statistical winner regardless of who is right or wrong — a compound conflict of interest sitting at the core of the product. In the pool model that party does not exist at all: the money is divided among the participants themselves.
We flag here what this table does not say: the absence of a house removes one of the objections, not all of them. Whoever builds the prohibition on the form of the contract — money staked by both sides contingent on an event — will not change his ruling because the identity of the payee changed. That is a serious objection, and we present it in its place shortly without belittling it.
The mechanism is simple and arithmetically verifiable. Everyone who stakes an amount on a given outcome places it into one pool alongside everyone who shares that view. At settlement, those on the correct outcome get their stakes back in full, then divide the opposite pool pro-rata by each one's share, after deducting a 10% commission from that losing pool alone. The formal expression: payout = staked amount × (1 + losing pool ÷ winning pool × (1 − 0.10)).
Take two worked examples. In the first, the winning pool is $800 and the losing pool is $200; someone who staked
This is not an arithmetic coincidence but a design condition: total payouts plus commission always equal the total staked into the market, and that reconciliation is asserted at every settlement. Its direct fiqh significance is that the platform holds no position, pays nothing from its own money, and earns nothing from money that was never generated. Add to that the fact that your return does not come from a house wagering on your being wrong, but from participants who chose the other side of their own free will under the same published rules.
And we state what does not exist as plainly as what does: no demo account, no play money, no signup bonus — real money only, in USDC on the Polygon network, with a minimum deposit of 0. Deposits are made by sending USDC to your own personal deposit address, and withdrawals are in USDC exclusively to a Polygon address you provide. Creating an account is free. For the practical steps see opening an account and your first trade.
The only disciplined way to put this question to someone qualified to rule on it is to set each fiqh objection against the specific mechanism that answers it, rather than against a general slogan. The table below does that, and includes a fourth column in which we commit to stating what we do not claim — because honesty about the limits of an argument is part of the argument.
The positive argument advanced in favour of the pool model is framed like this: when a group of people put their money into one pool, the proceeds are divided among them by calculated ratios, and nobody occupies the position of a house engineering its own edge, the picture is closer to risk pooling among participants on equal terms than to a game against an opponent holding a fixed advantage. Added to that is the fact that what moves the ratios is the pricing of public information available to everyone — economic data, announced decisions, published indicators — so that the market in its function produces a useful probability estimate, which is what our article on expected value in prediction markets explains.
But the limits of that argument must be stated clearly. The analogy to risk pooling stops at a certain point, because a participant in a cooperative pool covering a harm intends protection from a possible loss that would strike him, whereas the participant here intends profit from the outset. That is a difference in intent which structural similarity does not erase. Whoever holds intent to be a pillar of the characterisation will find in this a strong objection, and we do not dispute its strength.
Those who hold that event trading falls under maysir do not say so without evidence, and it would be unjust to present their view in a weak form and then answer it. The strongest of what is said in that direction comes to five objections, which we present as their proponents present them:
We cannot claim to have "answered" these objections conclusively. The most we say is that some of them address the form and some address the consequences, and that the structural objection in particular is untouched by anything we have detailed about the absence of a house or the source of the commission, because it does not hang the ruling on those things in the first place. Whoever adopts it has adopted a serious position; we neither contend with him nor describe him as excessively strict.
On the other side, whoever holds that the ruling turns on the substance and purpose of the transaction — equally-borne risk among participants, on published rules, with no party engineered to win, no riba, a verifiable formula, and full refunds when settlement is impossible — will find in that a substantive difference from the game of arrows over which the text was revealed. That too is a serious position. And when a question has two serious positions, the correct thing is to say: this is a matter of ijtihad, rather than manufacture a consensus that exists in neither direction.
One of the most useful aids to characterisation is to place the transaction on a map alongside other modern contracts, so that its nearness and distance become visible on each axis separately, instead of judging it as a single undifferentiated block. The table below compares on three axes: the source of the risk (did it exist before the contract, or did the contract create it?), who pays the winner, and where the fiqh discussion normally sits — without our issuing a ruling on any of them.
What this arrangement shows frankly is that prediction markets do not map fully onto either row. They part company with the house model on the most important axis — who pays the winner and who engineers his own edge — and they part company with cooperative insurance and hedging on an axis no less important, namely that the risk here did not exist before entry. Whoever weights the first axis arrives at a substantive distinction; whoever weights the second arrives at attaching it to maysir. That is precisely the reason for the disagreement, and not a weakness on either side.
Which is why the worst thing you can do to yourself is take a ready-made ruling from a table in an article — including this one. Tables isolate the point of dispute; the ruling comes from whoever is qualified to give it, once these specific axes are laid before him.
If you want to investigate this question seriously, the road is clear, and it begins with asking a qualified scholar and putting to him the mechanism, not the name. Carry four specific points to him: that the return comes from the participants' pool and not from the platform; that the 10% commission is taken from the losing pool alone, so it is zero when no profits are generated; that the stake is returned in full when the market is voided, or when there is no counterparty, or when there are no winners; and that the payout is computed by a published formula reconciled arithmetically at every settlement. Those are the facts on which the characterisation is built, and any question framed on anything else will draw an answer about a different transaction.
Risk statement — explicit and unsoftened: trading on PolySouq is conducted with real money (USDC on the Polygon network), the minimum deposit is 0, and withdrawals are in USDC exclusively. Losing your staked amount in full is a real and present possibility if the outcome goes against what you expected. There is no demo account, no play money and no signup bonus, and you cannot exit or cash out a position once the event has begun — the position runs to settlement, with the exception of cancelling a stake in football markets before the kickoff whistle, where the amount is refunded in full. Nothing in this article constitutes a guarantee of profit or personalised financial advice.
And we close with what we opened with: this article is not a fatwa, it does not claim that scholars agree on this question, and it attributes no opinion to anyone. Its aim is to place before you the classical definitions, the three grounds, the actual mechanism and the counter-objections in an honest form, because a question of this weight deserves analysis rather than a slogan. The ruling — as it always should be — belongs to the people of knowledge, and to your own conscience.
We are not in a position to issue a ruling, and this article is not a fatwa. This is a question of contemporary ijtihad in which serious scholarly disagreement exists. Whoever attaches the ruling to the outward form of the contract — money staked by both sides, contingent on an uncertain event — will class it with maysir. Whoever attaches it to the substance and purpose of the transaction will distinguish it from gambling, because there is no house with a structural edge, no riba, and the settlement rules are fully published. The right path is to put the detailed mechanism — not the brand name — to a qualified scholar, and if doubt remains in your heart, abstaining is safer.
No — structurally there is a fundamental difference from the ordinary betting model. On betting sites the house stands as your counterparty and builds a margin into the price that makes it the statistical winner over the long run regardless of whether you are right. At PolySouq the platform holds no position at all: everyone backing an outcome puts their money into one pool, and at settlement those who were right get their own stake back in full and then split the opposite pool pro-rata by their share. Your return comes from other participants who chose the other side under the same published rules; the platform pays nothing from its own money and never takes the other side of you. That said, we note honestly that anyone who builds the ruling on the form of the contract rather than the identity of the payer may not see this difference as decisive.
The possibility of loss alone is not maysir — otherwise buying shares, founding companies and buying inventory before prices move would all be maysir. As formulated in the fiqh of transactions, maysir combines four pillars: money staked by both sides; entitlement contingent on an uncertain event; the winner taking the loser's money with no recognised consideration; and chance dominating over skill. The first two pillars are undeniably present in prediction markets. The entire dispute is confined to the last two: is bearing risk and pricing public information a recognised consideration? And does analysis have a real effect on the outcome? Anyone who ends the discussion at the first two pillars has ended it before it began.
Riba presupposes a loan or debt carrying a stipulated increase against time, or a defect in the exchange of ribawi assets. Neither exists in PolySouq's structure: there is no lending between you and the platform in either direction, no interest credited on your balance, no time cost for keeping a position open however long the market runs, and no leverage or margin from which interest-bearing financing would arise. The commission is neither interest nor a price for time: it is 10%, taken from the losing pool alone — that is, out of profits actually generated — and it is zero when no profits are generated. The ruling on digital currencies themselves remains a separate question from ours here.
From a 10% commission taken from the losing pool only — that is, out of generated profits, not out of anyone's capital. The consequence of this design is that the platform earns only when real profits exist: if nobody is on the other side, commission is zero and everyone gets their money back; if nobody backed the winning outcome, the market is voided, all stakes are returned and commission is zero. Beyond that, total payouts plus commission always equal the total staked into the market, and this reconciliation is asserted at every settlement — no money is paid out that never came in, and no money that came in is left undistributed.
Your money is returned in full in every one of these cases, and the refund is never partial. If nobody is on the other side there are no losers, so every participant gets their full stake back and commission is zero. If nobody backed the winning outcome the market is voided, all stakes are returned and commission is zero. If the operator cancels the market, the refund is likewise complete. In football markets, cancelling your stake before kickoff means a full refund. In an ordinary settlement, the winner gets their own stake back in full on top of their share of the profits, while the loser forfeits the staked amount entirely.
No. There is no demo account, no play money, no free coins and no signup bonus — none of that is available, and everything runs on real money only. Creating an account is free, but any participation requires an actual deposit in USDC on the Polygon network with a
No. You cannot exit or cash out a position once the event has started; the position runs to final settlement. The single exception is football markets, where you can cancel your stake before the kickoff whistle and receive your money back in full. This is worth internalising before you enter, because it means your decision is taken once and cannot be reversed later if circumstances change — there are no stop-loss orders, no partial exits and no mechanism at all for trimming a position after the event is under way.
This is a serious objection which we present fairly and do not deny. The uncertainty is genuinely there in the final payout figure, because the sizes of the two pools keep changing while the market is open; you know the formula and you do not know the number. What is said in reply is that gharar is distinguished between the minor and tolerated and the excessive that leads to dispute, and that a great deal is known here: the amount you stake is set by you, the settlement rules, result source and timing are published before entry, the division formula is public and computed automatically with no room for dispute, and what you are actually acquiring is a proportional share in a pool determined at close. Is this gharar minor or excessive? That is a matter of ijtihad we do not claim to settle.
Deposits are made by sending USDC to your own personal deposit address on the Polygon network, with a
No. This article is not a fatwa, we are not a body authorised to issue one, we have not attributed an opinion to any named scholar or institution, and we do not claim that the people of knowledge are agreed on this question in either direction. Its function is to isolate the point of dispute: the definition of maysir and its pillars, the three grounds examined in any financial contract, the actual mechanism of the product in detail, and the counter-arguments presented at full strength. The ruling itself comes from whoever is qualified to give it, once these specific facts are put before him — and the decision is finally yours, on your own conscience.
