Prediction traders are pricing in a near-certain shift in congressional power, and at a rally ahead of the midterms Trump said the US would "take care" of Cuba after Iran.

Kalshi's market puts the odds of Republicans holding Congress at just 9%, making a split government in January the base case for traders. Consensus pricing this firm reprices sharply on any poll or news that challenges it.

A split Congress historically constrains major fiscal legislation, making sweeping tax changes or large spending packages harder to pass. That hits rate-sensitive sectors and any industry counting on deregulation or new appropriations for earnings growth.

Trump's Cuba remarks add geopolitical uncertainty that prediction markets have not yet built a dedicated contract around. Escalation talk this close to an election has historically raised volatility in defense-related assets and energy markets tied to Latin American supply routes.
