Prediction markets are signaling deep skepticism over the durability of the newly announced US-Iran ceasefire. Data from Polymarket and Kalshi show that traders have committed more than $16.5 million across contracts tied to when Washington will formally declare an end to military operations and whether the truce can survive its limited timeline.
How traders are pricing the truce
On Polymarket, the market tracking when President Donald Trump will officially declare US military operations against Iran over has reached a total volume of $16,419,168 since launching on February 28, 2026. The single most likely date is currently April 30, assigned a probability of 42% and backed by about $3.51 million in volume. By June 30, cumulative odds rise to 79%, while April 15 sits at just 10%, suggesting traders do not expect a quick formal resolution.
A separate Polymarket contract asks whether Trump or the US government will officially declare the ceasefire itself over before the two-week window expires. That market is smaller at $53,965 in volume, but its pricing is notably more cautious. April 21 leads with a 26% probability, followed by April 18 at 24%. The distribution implies that traders think the truce may last for several days, but many doubt it will survive the full two weeks.
Negotiations face a narrow and fragile window
The ceasefire, announced by Trump on April 7 and brokered by Pakistan, reportedly requires Iran to ensure the “full, immediate, and safe” reopening of the Strait of Hormuz. Any breach could undermine the entire agreement. Talks are scheduled for April 10 to 11 in Islamabad, with US Vice President JD Vance expected to lead the American delegation.
Markets are reacting not only to the agreement itself, but also to the conditions surrounding it. Iran has signaled that it wants a lasting end to hostilities rather than a temporary pause, and its proposal reportedly includes sanctions relief, compensation, a reduced US regional presence, and control-related demands tied to the strait. At the same time, reports of continued missile activity in the Gulf and Israeli strikes in Lebanon have added to concerns that the diplomatic opening could close quickly.
Kalshi shows little faith in long-term normalization
Kalshi’s pricing points to even weaker confidence in any sustained diplomatic reset. In the market tracking whether the US will reopen an embassy or consulate in Iran by January 1, 2027, the probability stands at only 16%. The “No” side trades at 84 cents, with total volume at $67,163. Sentiment in that market has been trending lower since early March.
That view contrasts with the short-term relief seen across broader markets after the ceasefire announcement. According to the report, global equities moved higher, oil briefly fell below $100 per barrel, and bitcoin climbed above $70,000. But that relief trade depends on the agreement holding, and prediction markets are clearly not ready to price in lasting stability.
What the markets are really saying
Overall, traders are not betting on immediate collapse alone; they are pricing a scenario in which de-escalation is possible but incomplete. The concentration of liquidity around late April and later dates suggests markets expect any genuine resolution to take time, if it comes at all. The upcoming Islamabad talks may determine whether this truce evolves into something more durable or proves to be only a brief pause in a still-volatile confrontation.
