The Polymarket prediction market, which posed the question "Iran closes its airspace by May 27?", has resolved to "No," with the market's final prices reflecting an overwhelming consensus against a major closure. Despite a period of significant geopolitical tension and localized flight restrictions in Iran leading up to the May 27 deadline, the specific conditions for a "Yes" resolution were not met.

This market garnered substantial interest, with a trading volume exceeding $2.7 million. It aimed to predict whether Iran would initiate a broad closure, cancellation, or suspension of commercial flights transiting, arriving in, and departing from Iranian airspace or a major Iranian Airspace region. Crucially, the market's definition of a "major closure" required a non-weather-related complete suspension of commercial arrivals and departures affecting at least two of five key airports: Imam Khomeini International Airport (IKA), Mehrabad Airport (THR), Mashhad International Airport (MHD), Shiraz International Airport (SYZ), or Isfahan International Airport (IFN).

Leading up to the May 27 deadline, the region experienced a volatile period. From May 22 to May 25, Iran temporarily closed its western airspace and suspended civil flight permits in the western sector of the Tehran Flight Information Region (OIIX). This move was reportedly in response to escalating tensions and concerns over potential new U.S. military strikes against Tehran. During this period, only eight airports across the country remained operational, including Tehran's Mehrabad and Imam Khomeini International airports. However, flight operations at these airports were subject to restrictions, including daylight-only hours and the requirement for new, per-flight approvals from the Iranian Civil Aviation Organization.

Further complicating the situation, Iran's Civil Aviation Organization issued a statement on May 23 denying any new official aviation notice imposing country-wide restrictions, asserting that flight conditions remained normal. By May 25, the U.S. and Iran had exchanged fire multiple times in the Persian Gulf, with Iran claiming to have shot down a U.S. drone. Despite these skirmishes, both nations reiterated their commitment to a broader ceasefire and ongoing diplomatic efforts. A tentative 60-day agreement to extend the ceasefire and begin nuclear program negotiations was reportedly reached on May 27, pending U.S. presidential approval.

While the western airspace restrictions were significant, they did not amount to a complete suspension of commercial arrivals and departures at the specified major airports, as required by the Polymarket's stringent definition. Reports indicated that IKA and THR, despite operating under restrictions, remained open for commercial flights. This distinction is critical, as partial closures or restrictions, even if extensive, would not trigger a "Yes" resolution according to the market's explicit rules. The European Union Aviation Safety Agency (EASA) also updated its Conflict Zones Information Bulletin on May 27, extending its validity but noting a high level of alert in Iran's airspace due to ongoing tensions, rather than a full closure.

The market's current prices, showing "No" at 0.9975 and "Yes" at 0.0025, reflect the market's accurate assessment that the events leading up to May 27, 2026, while indicative of heightened regional instability, did not fulfill the precise criteria for a "major closure" as defined by the prediction market. Traders correctly anticipated that Iran did not initiate a broad and complete suspension of commercial flights across its key aviation hubs by the stipulated deadline.
