US midterms Polymarket odds now price a 60% chance that Democrats take control of the US Senate, according to CNBC\u2019s review of prediction-market data published September 16, 2026. Kalshi<\/a>, the other major regulated prediction-market platform, has the same outcome at roughly 55%.<\/p>\n

Neither number is a forecast \u2013 both are market-implied probabilities, the going rate for a contract that pays out only if Democrats actually win the chamber in November. A 59% price sounds like a lean, but it is still close to a coin flip. Republicans currently hold 22 of the 35 Senate seats up for election this cycle.<\/p>\n

This includes special elections in Ohio and Florida, and Democrats cannot take the majority without flipping several states that Donald Trump won by 10 percentage points or more in 2024, Alaska, Texas, and Ohio among them.<\/p>\n\n
