Democrats Favored to Take Senate, But Tossup Remains Close
Prediction market traders now give Democrats a 54–59% chance of winning the Senate. That marks a reversal from February, when Republicans held roughly 60% odds on the same platforms.
- 54% odds Democrats win the Senate, per Kalshi; 59% on Polymarket.
- 6.7 points: Democrats' current lead on the RealClearPolitics generic ballot average.
- 6 Senate races rated tossups by Cook Political Report: Alaska, Iowa, Maine, Michigan, Ohio, Texas.
- U.S. oil prices now exceed $100 per barrel; diesel is at an all-time high.
Why it matters: Republicans must defend 20 of 33 contested Senate seats. Democrats need to flip states Trump carried by double digits in 2024.
- Rising gas prices have weighed on Trump's approval rating since the U.S.-Iran war began in February.
- A Cook Political Report poll of 37 competitive House districts found a 7-point swing toward Democrats since 2024.
