Polymarket odds for Hormuz traffic normalizing by year-end slide to 52.5%

Polymarket Reprices Strait of Hormuz “Traffic Normalizes by Dec. 31” After Ninth Night of U.S. Strikes

On Polymarket, the contract “Strait of Hormuz traffic returns to normal by December 31?” is priced at 52.5% Yes on $5.40M matched volume, after a sharp repricing from 85.5%. The move follows a fresh headline about U.S. forces striking Iran for a ninth consecutive night, and the market’s shift is visible directly in the implied probability.

Key Takeaways

• Polymarket currently implies a 52.5% chance (Yes) that Strait of Hormuz traffic returns to normal by Dec. 31.
• Traders repriced the contract lower after a new headline about continued U.S. strikes, pushing odds down from 85.5% to 52.5%.
• Settlement is tied to conditions by 2026-12-31; near-term tape shows moderate volatility with -2.0 pp over both 24h and 7d.

A brief headline reports that U.S. forces struck Iran for the ninth consecutive night, citing Central Command. The update adds to ongoing conflict-related uncertainty that traders may connect to regional shipping risk and timelines.

Odds Collapse From 85.5% to 52.5% Yes on $5.40M Matched Volume—Coin-Flip Pricing Near 50%

At 52.5% Yes vs 47.5% No, Polymarket is now close to a coin-flip on whether traffic normalizes by year-end—down 33.0 percentage points from the prior 85.5% reference, a large confidence reset rather than a marginal drift. With $5,403,416 matched, this isn’t a thin-market blip; the price is reflecting meaningful two-sided disagreement about the timeline. The contract is a simple binary: buying Yes pays out if the “returns to normal by December 31” condition is met by the 2026-12-31 resolution date; buying No pays out otherwise, so the entire debate is being expressed as a single probability rather than a narrative. Even while the broader summary flags bearish trend, moderate momentum, and reversal_detected=true, the shorter-window stats show only -2.0 pp over both 24h and 7d—suggesting the big repricing is the dominant signal, while the latest tape has been comparatively stable around its new range.

Watch whether the market can hold above the 50% line: a sustained move back toward the mid-80s would indicate traders re-embracing a fast-normalization timeline, while continued sub-50% pricing would imply the year-end deadline is being treated as more likely to be missed as the contract approaches 2026-12-31.

On the tail-risk side, “Will the U.S. invade Iran before 2027?” sits at 69.5% No on $44,953,022, and leadership-path pricing appears in “Iran leader end of 2026?” at 73.3% on $32,658,882—useful cross-checks for how the platform is distributing risk across horizons.
