Prediction markets are currently pointing to a split result in the 2026 midterms: Democrats are favored to win back the U.S. House, while Republicans hold a narrower edge to keep the Senate.
According to market prices cited by KuCoin from Polymarket, Democrats were at 86% odds to take House control, with about $9 million traded on that market. On the Senate side, Republicans were priced at 56% to hold the chamber, with roughly $3 million in volume and an implied 49-51 seat split.
For readers tracking political prediction markets, the bigger takeaway may be how much money is already flowing into individual races and primaries on Kalshi.
Florida market among Kalshi’s busiest
Kalshi’s Florida Republican governor primary between Byron Donalds and James Fishback had drawn $10.3 million in trading volume, with Donalds favored at 96%, according to the source. The report also said southern Senate and governor primaries in Texas, Kentucky, California and Florida account for more than $70 million of Kalshi’s total volume.
That puts Florida in the middle of a broader surge in election-market activity rather than as a standalone outlier. The largest single Kalshi midterm market cited in the report was the Kentucky 4th District Republican primary between Ed Gallrein and Thomas Massie, which had nearly $22 million in volume. Texas Senate primaries were also heavily traded, including $18.4 million in the Republican contest between Ken Paxton and John Cornyn and $14.6 million in the Democratic primary between James Talarico and Jasmine Crockett.
What the broader market is signaling
Beyond chamber control, the source highlighted active pricing on ballot measures and state races. Among the examples: Nevada’s abortion protection amendment was priced at 92% to pass, while California’s proposed one-time wealth tax on billionaires stood at 34% with $4 million traded. Michigan’s proposed state constitution rewrite was priced at 19%, and a Missouri measure to ban abortion and gender transition care for minors was at 18%.
Polymarket’s state-by-state Senate map covered 24 races. Republicans were trading above 90% in Nebraska, Montana, Tennessee and Mississippi, while Democrats were above 94% in Colorado, Minnesota, New Jersey and New Mexico. Ohio, Illinois and Kentucky were each listed at 50%, underscoring how narrowly traders currently see those contests.
For Florida readers, the practical point is that prediction markets are being used as a real-time measure of political expectations, with prices and volumes shifting as traders put capital behind those views. As always with these markets, odds are snapshots rather than guarantees, and the source did not detail methodology or contract rules for the prices cited.
