US-Iran Nuclear Deal by Dec. 31, 2026: Polymarket Odds Rise to 45.5% After Geopolitical Headline
Polymarket traders nudged up pricing on the “US-Iran Final Nuclear Deal by…?” ladder after a separate geopolitical headline crossed the wires, lifting the market’s leading contract. The implied odds for a US-Iran final nuclear deal by December 31, 2026 rose to 45.5% from 44.5%.
Key Takeaways
- Polymarket prices a 45.5% chance of a US-Iran final nuclear deal by December 31, 2026 (Yes 45.5%, No 54.5%).
- The contract edged higher by 1.0 percentage point even as the top related headline centered on Ukraine-Russia developments rather than Iran.
- The market’s listed resolution date is August 31, 2026, while the ladder spans deadlines from June 30 through December 31, 2026.
Ukrainian President Volodymyr Zelenskyy said Ukraine hit Russia’s Dubna satellite site for a second time. The claim points to continued Ukrainian strikes on Russian facilities linked to space or satellite capabilities. Zelenskyy framed the action as part of Ukraine’s ongoing military efforts against Russian infrastructure. The report did not provide further details in the available snippet. The development comes as fighting between Ukraine and Russia continues.
Polymarket Data: $3.48M Volume Concentrated in Dec. 31 Contract as Earlier 2026 Deadlines Trade 0.15%–28% Yes
On Polymarket, the “US-Iran Final Nuclear Deal by…?” ladder shows the highest implied probability at the December 31 deadline, with Yes at 45.5% and No at 54.5% on $3,479,768 in volume. Earlier deadlines are priced materially lower: September 30 is Yes 28.0% / No 72.0%, while August 31 is Yes 23.5% / No 76.5%. Near-term timing is discounted sharply, with July 31 at Yes 2.75% / No 97.25% and June 30 at Yes 0.15% / No 99.85%. The curve implies traders see a meaningful chance of a deal later in 2026, but little probability assigned to a breakthrough in the next several weeks.
Watch whether pricing rotates toward earlier rungs such as August 18 (Yes 19.5% / No 80.5%) or August 31 (Yes 23.5% / No 76.5%), and whether total volume continues to concentrate in the December 31 contract as the market approaches the listed resolution date of August 31, 2026.
