Kalshi 62%

record: CMSIG2026101306 | category: momentum-repricing | target: CM-EVT-T5VXKJT451 | published: 2026-10-13

4-bullet brief | narrative

The Kalshi contract prices 62% on Republicans controlling at least one chamber of Congress after the 2026 midterms.
Trump's Alaska rally and the Guilfoyle resignation underscore GOP concern about retaining Congress, consistent with a market short of full conviction at 62%.
A companion Kalshi contract (CM-EVT-CRMKQSR4R6) prices 91% on a new Montana senator being elected, flagging one competitive seat already likely to flip.
Resolves via Bureau of Labor Statistics per the named source, though the operative data is the congressional election outcome on November 3.
