Trump renames Strait of Hormuz to "Strait of Trump" by May 31?

Platform comparison

Market context

The Strait of Hormuz, a 54-nautical-mile waterway between Iran and Oman, handles roughly one-third of global seaborne oil trade. The question of whether Donald Trump will formally rename it to include his name by May 2026 is currently priced at 1% on Polymarket, reflecting minimal conviction that such an announcement will occur. At this probability, YES tokens trade near worthless whilst NO tokens command near-full value in USDC terms on Polygon.

Trump has a documented history of affixing his name to properties and projects—Trump Tower, Trump University, Trump International Golf Club—but these have been commercial or personal ventures rather than geopolitical rebranding efforts. The only comparable precedent is his 2017 proposal to rename the Gulf of Mexico the "Gulf of America," which gained no official traction despite repeated mentions. The Strait of Hormuz carries far greater international complexity, requiring coordination with the International Maritime Organization and acceptance from littoral states Iran and Oman, neither of which would likely endorse such a change. This historical pattern suggests renaming efforts face structural barriers beyond presidential preference.

Traders monitoring this contract should track Trump administration statements on Iran policy, maritime strategy announcements, and any executive orders regarding geographical nomenclature. The resolution hinges on "official" U.S. government adoption rather than Trump's personal rhetoric alone. Given the 16-month window and the absence of any recent geopolitical catalyst pointing toward such action, the 1% pricing appears consistent with base-rate expectations for low-probability symbolic gestures with minimal institutional support.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does it cost to trade on PolyGram?

Zero. PolyGram routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
