Live prediction market odds for "US recognizes Reza Pahlavi as leader of Iran in 2026?". Before 2027 leads at 5.1%. Next is Reza Pahlavi at 5%. $5.8M has traded across 3 outcomes on Kalshi and Polymarket. The market is expected to resolve by Jan 1, 2027.
This market will resolve to "Yes" if the Trump administration announces that the United States officially recognizes Reza Pahlavi as the "leader of Iran" by December 31, 2026, 11:59 ET. Otherwise, this market will resolve to "No". Roles that could qualify for "leader of Iran" status include, but are not limited to, "head of state," "prime minister," or other similar roles that give him primary executive authority in the territory of Iran. A qualifying US statement must be direct and unqualified. Conditional, hypothetical, supportive, or implied statements do not count. The primary resolution source for this market will be official information from the US government and Donald Trump, however a consensus of credible reporting will also be used.
It is the price of a Yes contract that pays $1 if the outcome happens. A 14¢ price means traders put the chance near 14%. Where two venues list the same outcome, we blend their last prices, weighting the venue with more trading volume more heavily (neither counts for less than a quarter). When only one outcome can win, each venue’s prices add up to a little over 100% (its margin); the fair chance removes that margin so the outcomes add up to exactly 100%.
A Yes contract pays $1 if it wins, so at the best ask a $100 stake buys 100 ÷ ask contracts. At 18¢ that is about 555 contracts, paying $556 (5.56x) if Yes happens. Venue fees and price slippage on larger orders are not included.
Each venue has its own traders, fees and order book. Contracts can also settle on slightly different terms, which is why each row lists how closely the rules match.
Only when you can buy Yes on one venue below what someone pays for Yes on the other, after fees, and both contracts settle the same way. We show the executable bid and ask so you can check.
