Will the Iran ceasefire hold through the weekend?

May 21, 2026 · flowframe Pulse

Polymarket traders are putting more weight on the prospect of a quiet weekend in the Middle East. The odds for the Iran ceasefire lasting through May 24 rose from 83¢ to 86¢ as of this morning. It's a steady climb backed by $0.5M in total volume. Despite friction in the Gulf, the tape shows that the market doesn't expect a return to "Operation Epic Fury" strikes quite yet.

The shift follows direct signals from Washington. President Trump told reporters the U.S. is in the "final stages" of negotiations with Tehran, extending the truce to review an Iranian response delivered via Pakistani mediators. It's not a clean peace. US Marines just boarded an Iranian-flagged tanker for a blockade violation, and Benjamin Netanyahu reportedly slammed the proposed deal during a tense call with Trump. Even with intelligence reports that Iran is rebuilding drone production, the White House is sticking to the diplomatic window. Traders are choosing to believe the talk over the tankers for now.

The pressure is on the Pakistani mediators. Their army chief is in Tehran today trying to bridge the final gaps on a 14-point roadmap. If they can't produce a signed framework by the May 24 cutoff, Trump's grace period for "getting the right answers" ends. We're looking for an official announcement out of Islamabad within the next forty-eight hours.
