Marco Rubio’s warning against Iran’s control over international waterways casts doubt on a US agreement to Iranian demands by April 30. The odds of Trump agreeing to Iranian oil sanction relief now sit at 0.8% YES.

Rubio’s stance signals a hardline US approach, making an agreement on Iranian demands less likely. The Trump Iran Demands market holds at 0.8%, consistent with Rubio’s rhetoric that the Strait of Hormuz will remain an international commons. The US-Iran nuclear deal by April 30 market dropped from 2% to 0.8% in just 24 hours.

Both markets are showing thin trading volumes, $950 in actual USDC, indicating traders are skeptical of any rapid resolution. The largest move in the nuclear deal market was a 49-point spike, which reflects volatility but not lasting conviction. The cost to move these odds 5 points is just over $1,200, so any single large order could shift prices quickly.

Rubio’s comments reflect a consistent US policy of rejecting Iranian control over strategic waterways, a stance consistent with previous US actions, including the naval blockade. For traders, betting on a YES outcome costs 0.8¢ for a 125x return, but only if you believe Trump’s administration will reverse course in the next two days.

Watch for announcements from the White House or any last-minute diplomatic maneuvers. Trump’s communications, particularly on Truth Social, could shift market sentiment rapidly. But without concrete changes in US policy, odds of any agreement by the end of April remain near zero.
