US airstrikes against Iran continued for the tenth consecutive night Thursday, as escalating tensions in the strategic Strait of Hormuz raised fears of a regional airspace shutdown. A prediction market now puts the probability of airspace closure by August 31 at 46.5 percent.
Tenth Night of Strikes
The latest round of US military action marks the longest sustained campaign in the region since the beginning of the current conflict. The strikes have targeted military installations and infrastructure linked to Iran's Revolutionary Guard Corps, according to official statements. No casualty figures have been released for the most recent wave.
The operations come amid a broader standoff that has drawn in naval forces from multiple countries. The Strait of Hormuz, a narrow waterway through which about a fifth of the world's oil passes, has become a flashpoint in recent weeks.
Strait of Hormuz in the Crosshairs
Iran has periodically threatened to disrupt shipping through the strait in response to military pressure. The US Navy has increased patrols in the area, and commercial vessels have altered routes to avoid the zone. The combination of airstrikes and naval maneuvers has created a volatile environment for both military and civilian aircraft.
Commercial airlines have already begun rerouting flights that normally pass over Iranian airspace. The Federal Aviation Administration has issued warnings to US carriers about the risks of operating near the conflict zone. A full closure of the airspace would force even more extensive detours, adding hours to flights between Europe and Asia.
Airspace Closure Odds
A prediction market that tracks geopolitical risks shows a 46.5 percent chance that the airspace over the region will be closed to civilian traffic by the end of August. The figure has risen steadily since the strikes began, reflecting growing uncertainty about the trajectory of the conflict.
Prediction markets aggregate bets from traders on specific outcomes. The current odds suggest that nearly half of market participants expect a closure within the next two weeks. The market does not assign a specific timeline for how long any closure would last.
Airspace closures are rare but not unprecedented. In recent years, conflicts in Ukraine and the Middle East have led to temporary no-fly zones or restricted areas. A closure over the Strait of Hormuz would affect major air routes and could disrupt global aviation schedules.
The strikes show no signs of abating. The US military has not indicated when the current operation might end. Iranian officials have vowed to retaliate, though they have not specified what form that retaliation might take. The situation remains fluid, with both sides signaling readiness for further escalation.
