record: CMSIG2026092007 | category: momentum-repricing | target: CM-EVT-0DMSQTKVX3 | published: 2026-09-20

4-bullet brief | narrative

The ladder prices 74% odds Trump's approval stays below 37%, with volume up 71x day over day, signaling intense fresh attention on this contract.
Houthi ballistic missile attack on Riyadh and US warnings of rapid escalation are the likely catalyst driving the volume surge on the approval floor contract.
The distribution shows only 10% odds approval falls below 33%, suggesting the market sees a floor around the 34-36% range, not a collapse.
A companion Polymarket contract on Trump ceasing to be president before 2027 holds at just 5%, indicating the approval pressure is not being read as an existential political risk.
