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

We track Trump renames Strait of Hormuz to "Strait of Trump" by May 31? on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
