Prediction markets put the probability at 40%: Iran closes its airspace by May 31. Currently, markets are divided (40% YES, 60% NO). Iran says it has replied to US proposal as reported drone strikes strain ceasefire.
US President Donald Trump stated on May 10 that Iran's latest counterproposal to a US peace plan is "totally unacceptable," according to the Institute for the Study of War. Iranian state media reported the same day that Tehran had transmitted its response to Washington via Pakistani mediators, with the counterproposal reportedly calling for an end to the war, the "gradual opening of the Strait of Hormuz," and the lifting of the US naval blockade on Iran. Hours earlier, Kuwait's army said it detected and neutralized several hostile drones in its airspace at dawn — the first such incident since the April ceasefire — while similar drone incursions were reported in the UAE, Qatar and Iraq, straining the month-old truce.

The question of whether iran closes its airspace by may 31 sits at the intersection of two pressures: regional escalation risk and Tehran's diplomatic posture. Hawks point to the renewed drone activity across four Gulf states on May 10 as evidence that the ceasefire is fraying and that an Iranian airspace closure could follow any US strike. Analysts caution the opposite — that Iran's Revolutionary Guard publicly committed on May 6 to safe passage through the Strait of Hormuz under unspecified procedures, after Trump paused a US military effort to escort merchant vessels. Saudi Arabia separately informed Washington it would not permit US military overflight for any renewed campaign under Operation Project Freedom, narrowing the operational window in which Iran would need to retaliate by sealing its skies.

Whether iran closes its airspace by may 31 will be determined by the trajectory of the next two weeks of US-Iran exchanges. With Trump rejecting the counterproposal and drone strikes resuming across the Gulf, the structural factor is whether either side opts to break the April ceasefire before the proposal window collapses. Iran has historically kept commercial airspace open even during active hostilities — closure would signal preparation for direct kinetic exchange rather than retaliation already underway. The Saudi overflight refusal, combined with Tehran's stated willingness to gradually reopen Hormuz, suggests both capitals are still calibrating leverage rather than committing to escalation. Resolution by May 31 hinges on whether Trump's rejection translates into renewed military action or another round of mediated talks through Islamabad. [Guardian, May 10]
