Market context

Iranian forces have already demonstrated a willingness to launch kinetic strikes against commercial shipping in the Strait of Hormuz, with the Islamic Revolutionary Guard Corps explicitly claiming responsibility for drone attacks on UAE-flagged tankers and damage to South Korean vessels[1]. The US has responded with direct airstrikes on Iranian missile and drone storage sites following a drone attack on the Ever Lovely cargo ship, marking the most significant test of the fragile ceasefire reached just a week prior[3][5]. This recent escalation confirms that the threshold for targeting commercial vessels has been crossed, yet the market-implied 4% probability suggests traders believe the current ceasefire framework will prevent further Iranian actions against commercial ships before the settlement window closes in July 2026[2].

Historically, Iranian attacks on commercial shipping have been sporadic and often tied to specific political grievances rather than sustained campaigns, with proxy forces like the Houthis frequently conducting similar operations that do not count toward this market’s resolution[1]. The critical distinction here is that only actions explicitly claimed by the Islamic Republic of Iran or confirmed to originate from Iranian territory will resolve the market, excluding proxy attacks by Hezbollah or Houthis[1]. Traders should monitor official announcements from the IRGC regarding “transit protocols” and any US-Iran diplomatic breakthroughs, as the US has established an enhanced security area south of typical shipping routes to counter economic disruptions[1]. The settlement of this market hinges on whether the ceasefire holds or unravels further, with Vice President JD Vance stating that “violence will be met with violence” if Iran breaches the agreement again[2].

Key catalysts include the IRGC’s threat to target vessels not adhering to designated transit routes and the US military’s continued presence guiding ships through the waterway under Project Freedom[1]. Any new drone attacks on commercial vessels, particularly those explicitly claimed by Tehran, would immediately invalidate the current low probability and signal a collapse of the interim understanding[3]. The market will resolve to “Yes” only if Iranian forces conduct a kinetic strike on or seize control of a commercial ship, excluding attacks on military vessels[1]. With the settlement window ending in July 2026, the immediate focus is on whether the US-Iran ceasefire survives the next few weeks of heightened tension in the Strait[2].

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

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
