Market context

Saudi Arabia and Kuwait have officially lifted all restrictions on U.S. military access to their bases and airspace, removing a critical hurdle for President Trump’s “Project Freedom” operation in the Strait of Hormuz. This reversal, confirmed by U.S. and Saudi officials, occurred after the Gulf states previously suspended access following the initiation of the American mission aimed at reopening the strategic waterway. The current market-implied probability of 0% for a future ban reflects this decisive policy shift, as standing access is now the norm rather than an exception.

Historically, similar access denials were isolated to specific operational windows, such as when Saudi Arabia refused airspace for operations against Iran in 2025, prompting the White House to suspend Project Freedom temporarily. Unlike those transient refusals, the May 2026 agreement established a permanent standing policy, making a future ban highly improbable unless a major geopolitical rupture occurs. Traders comparing platforms like Polymarket, Kalshi, and Betfair should note that while Polymarket displays decimal odds and Kalshi uses implied probabilities, all three correctly price this event at near-zero due to the confirmed policy lift, though fee structures and KYC requirements vary significantly across these books.

Key catalysts to monitor include any sudden announcements from the U.S. Department of Defense regarding changes in Middle East strategy or new Iranian threats that might alter Saudi security calculations. Recent reporting from Reuters on 7 May 2026 underscores the permanence of the current access agreement, suggesting that only a drastic shift in regional alliances could trigger a reversal. Traders should also watch scheduled U.S.-Saudi defence summits in late 2026, as these could reaffirm or unexpectedly modify the existing standing policy on military aircraft access.
