4-bullet brief | narrative

Kalshi places 89% on the Republican candidate winning the TX-34 House seat, resolving via the Library of Congress; trading volume surged 6,564% day over day.
The sharp volume spike signals fresh attention on this seat as midterm campaigns enter their final days and early voting accelerates.
TX-34 has historically been competitive; the 89% pricing with a volume surge suggests the market is moving to price the Republican as a strong but not certain favorite.
The Kalshi contract on Republicans holding more governorships than Democrats after the midterms (CM-EVT-4DFCBXLZN6) sits at 74%, framing a broadly favorable but not dominant Republican map.
