4-bullet brief | narrative

Kalshi prices the midterm elections proceeding on schedule at 93%, treating legal challenges like the California ballot dispute as unlikely to derail the November 3 date.
The DOJ ballot challenge being rejected by an appeals court is consistent with the market's near-certainty; legal friction is not moving the probability toward disruption.
A companion Polymarket contract on the California 25th District winner (CM-EVT-3DFWF9RX19) sits at 94%, showing district-level markets also pricing normal resolution timelines.
Resolves via The Washington Post; Kalshi will look for independent reporting confirming elections occurred as scheduled on November 3.
