US x Iran ceasefire continues through November 15 priced at 61% on Polymarket, up 8.5 points, on $276K traded

Ceasefire contract moves higher

Polymarket’s contract on whether the US x Iran ceasefire continues through November 15 was priced at 61%, up 8.5 percentage points, with $276K traded, according to the supplied market update published Oct 18, 2026, at 4:09 AM ET.

The accompanying summary reported no significant new platform headline in the preceding 15 minutes. Its news search found only recirculated items already flagged on Oct. 17, leaving the material without an identified fresh catalyst for the price increase.

Different deadlines, different contracts

According to predictionbubbles.net, its movers board measures probability-point changes over 24 hours using prices from Polymarket and Kalshi, with updates every 15 minutes. The supplied page carries a venue-data timestamp of 18 Oct 2026, 08:19 UTC.

That page names the US x Iran ceasefire contract running through November 22 as a biggest mover—not the November 15 contract in the headline. The excerpt does not provide a price, change or trading volume for November 22, so it cannot establish how the two deadlines compare.

The board ranks markets by the size of their probability changes rather than trading volume. While the headline’s $276K provides activity context, the supplied material does not establish order-book depth or explain which trades drove the November 15 repricing.

What it means for prediction markets

• The move reflects pricing, not confirmation: The 61% reading and 8.5-point rise indicate a higher market-implied probability, not verification that the ceasefire will last through November 15.
• Keep settlement dates separate: November 15 and November 22 are distinct outcomes; the supplied figures cannot be transferred between them.
• The catalyst remains unclear: A quiet 15-minute news window does not explain a 24-hour market move, and the material identifies no new development behind the increase.
