Full analysis
The 2026 midterm Senate map is shaping up to be one of the closest in recent memory. The Kalshi contract CONTROLS-2026-R is trading at 52¢ with a 1¢ spread and over 364,945 contracts exchanged — making it the highest-volume election market in the dataset. Democrats hold their best pick-up opportunities in Ohio (SENATEOHS-26-D at 51¢, vol 100,575) and Michigan (SENATEMI-26-D at 57¢, vol 36,492), while Republicans are favored in Texas (SENATETX-26-R at 50¢, vol 37,760) and Alaska (SENATEAK-26-R at 45¢, vol 17,809). The Florida gubernatorial primary is seeing massive volume in the Byron Donalds contract (KXGOVFLNOMR-26-BD at 99¢, vol 2,073,797), signaling traders see this race as effectively over. The 2026 Senate control market is the key macro bet to watch as campaign finance reports and polling shifts could trigger significant re-pricing. Democrats are defending a narrow majority, and even a net loss of one seat could flip control. Traders should pay close attention to the Ohio and Michigan Senate primaries, where margin-of-victory markets (KXPRIMARYMOV-KXSENAT) offer granular insight into candidate strength.
