Kalshi’s contract on whether the US will agree to a new Iranian nuclear deal before Mar 1, 2027 was priced at 36.0%, up 17 probability points, with $87K traded, in the update published Oct 23, 2026 at 6:54 PM ET.
According to PredictionBubbles, the contract ranked among the largest upward moves in its political/election category. The increase represents a substantial shift in pricing, although the market still assigned a probability below 50% to an agreement before the deadline.
What the ranking captures
PredictionBubbles measures changes over 24 hours using prices from Kalshi and Polymarket, refreshing its board every 15 minutes. The supplied snapshot records venue data retrieved on 23 Oct 2026 at 22:44 UTC.
The board covers 1,982 markets with lifespans longer than 14 days. Only open contracts with a valid 24-hour price comparison qualify, and rankings depend on the size of the probability-point change—not trading volume or liquidity.
The supplied material does not identify a diplomatic development behind the Iranian nuclear-deal contract’s rise. Nor does it provide the contract’s detailed settlement criteria or order-book depth. The reported move therefore establishes a change in market pricing, rather than evidence that negotiations have advanced.
What it means for prediction markets
Direction and level differ: The 17-point rise marks stronger pricing for an agreement, but the 36.0% level remains below an even chance.
Volume is context, not confirmation: The reported $87K traded does not, by itself, establish market depth or explain the repricing.
The deadline matters: This contract concerns US agreement before Mar 1, 2027, not the broader possibility of an eventual Iranian nuclear deal.
The catalyst remains unclear: PredictionBubbles’ ranking identifies movement; the supplied reporting does not establish what drove it.
