Pronóstico: Which countries will send warships through the Strait of Hormuz by July 31?

Platform comparison

Market context

The Strait of Hormuz, a 54-nautical-mile waterway between Iran and Oman, remains one of the world's most strategically contested maritime passages. Roughly one-third of all seaborne traded oil transits through it annually. The question of which countries will deploy warships through the strait by end-July 2026 hinges on whether geopolitical tensions—particularly between Iran and Western powers—escalate beyond current posturing into active naval operations or freedom-of-navigation exercises that require visible military presence.

Historical precedent suggests warship transits occur in clusters tied to specific flashpoints. The United States Navy has conducted regular Strait passages since the 1980s, whilst British, French, and Australian vessels have made occasional transits during periods of heightened Iran tensions. Between 2019 and 2022, multiple Western navies increased frequency following the Houthi attacks on commercial shipping and Iranian seizures of tankers. However, extended periods of relative stability—such as 2016–2018 under the JCPOA—saw minimal military activity. The current 4% probability reflects a market assessment that routine or escalatory transits remain unlikely within the next 18 months absent a major triggering event.

Traders should monitor three variables: announcements of new US or allied naval deployments to the Persian Gulf, any Iranian provocations targeting commercial shipping or regional assets, and developments in nuclear negotiations that could shift Western military posture. Recent reporting from Reuters and regional defence ministries will signal operational intent weeks before actual transits occur. Scheduled maintenance cycles and multinational exercise calendars also matter; planned operations are typically telegraphed through official channels.

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

What are live sports odds on Polymarket?

Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.

How fast do sports winnings settle?

Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
