Polymarket odds dip to 67% on Iran Hormuz fees by Dec 31 after strike reports

Polymarket Dips After Qeshm Island Strike Reports, but Hormuz Fee Odds Hold Near 67% by Dec. 31

Polymarket traders are pricing a 67% chance that Iran charges Hormuz fees by the December 31 strike on the market’s date ladder, with $1,016,022 matched and the leading strike down 2.5 points from 69.5%. The move follows fresh reports of explosions and strikes around Bandar Abbas and Qeshm Island, offering a clear read on how traders are mapping conflict headlines into a timeline bet.

Key Takeaways

• Polymarket’s leading strike is “by December 31” at 67% Yes / 33% No.
• After the Qeshm Island strike/explosion reports, the leading strike slipped 2.5 points (69.5% to 67%), signaling a modest pullback in near-term fee expectations.
• The market resolves by 2026-08-31 23:59 UTC, so positioning is about whether the policy is implemented by then—not the later date labels themselves.

Iranian state media said nearly a dozen “enemy projectiles” targeted Qeshm Island, with new explosions reported in Bandar Abbas and on Qeshm Island. The report described a fifth wave of US strikes since a ceasefire agreement was signed three weeks earlier, said military sites in Hormozgan province were targeted, and said Tehran retaliated against US military assets in the region.

Date-Ladder Breakdown: $1.016M Matched, 67% (Dec 31) vs 50.5% (Aug 31) and 6.65% (Jul 15)

This is a price-ladder (date-ladder) contract: each strike is a separate Yes/No market on whether Iran charges Hormuz fees by that labeled date, and the ladder’s shape shows where traders place the timing risk. The front end remains heavily discounted—July 15 is 6.65% Yes / 93.35% No and July 31 is 15.5% Yes / 84.5% No—while the curve steepens into late summer, with August 31 at 50.5% Yes / 49.5% No and October 31 at 61.5% Yes / 38.5% No, culminating in December 31 at 67% Yes / 33% No. Despite the headline catalyst, the leading strike is down 2.5 points to 67% on $1,016,022 volume, consistent with the market’s “moderate” volatility and “moderate” momentum rather than a sharp repricing. The historical summary flags a bearish trend but strengthening consensus, which fits a ladder where traders are converging on “later rather than sooner,” even as the mid-curve (around the August 31 strike) stays close to a coin flip—an indicator of ongoing disagreement about implementation timing. Also critical: the market’s resolution date is 2026-08-31 23:59 UTC, so the actionable settlement window is through that timestamp; traders should interpret later strikes as ladder pricing signals, not as the contract’s own settlement date.

Watch whether pricing compresses toward the August 31 strike (currently 50.5% Yes / 49.5% No) or re-steepens toward December 31 (67% Yes / 33% No); a shift in the curve, not just the headline-leading strike, will show whether traders are bringing expected implementation forward. Also watch if the $1.0M+ matched volume continues to rise alongside the 24h/7d net move (both +12.5 in the summary), which would indicate the market is still actively incorporating new information into the timeline.

If you’re tracking how this timing risk propagates across Polymarket, a few adjacent contracts are drawing heavy attention and can help triangulate sentiment shifts. “Will the U.S. invade Iran before 2027?” is sitting at 80.5% No on $41,334,366 volume, while the operational side is even more one-sided with “Strait of Hormuz traffic returns to normal by July 15?” at 99.65% No ($9,959,120) and “Strait of Hormuz traffic returns to normal by July 31?” at 97.0% No ($16,189,645). On the diplomacy/airspace track, traders are also watching “Iran announces withdrawal from MOU negotiations by…?” (38.5% leading on August 15, $4,810,903) and “Iran full airspace closure by…?” (40.0% leading on August 31, $3,456,886) for any repricing that could spill back into broader risk and volatility setups.
