In prediction markets you can trade a contract on a clear question about the Tadawul TASI index — such as the points range it will close in on a given date, or which sector will deliver the highest return in a set quarter — settled against official Tadawul (Saudi Exchange) data.
No leverage, no riba, and the loss is capped at the contract cost. On PolySouq — the leading Arabic event and prediction-market platform — you try it with real money — and your capital is at risk.
The market poses settleable questions such as: "Which points range will the TASI close in at month-end?" or "Which sector will deliver the highest total return this quarter?" You pick the answer you find most likely, and the contract price reflects its probability. This sits alongside a family of Tadawul markets such as Aramco event predictions and IPO predictions.
TASI range probabilities respond to oil prices, listed-company earnings, monetary policy and regional investor sentiment. Tracking these helps you estimate the most likely range. See how global events move the odds to understand the mechanism, and for the Saudi market specifically the Saudi Arabia prediction-markets guide.
The market settles against official Tadawul data published on the set date — the index closing number or sector return as released by the official body. This removes ambiguity and makes the outcome verifiable by everyone, exactly as we explain in how PolySouq settles its markets transparently.
