Republicans win Trifecta with Senate Supermajority in midterms?

Republicans win Trifecta with Senate Supermajority in midterms? is a 2026 election prediction market tracking a specific Republican sweep in the U.S. midterms. The forecast asks whether, after the November 3, 2026 elections, the Republican Party will control the U.S. presidency, win a majority in the House of Representatives, and hold at least 60 seats in the Senate. In practical terms, this is a bet on a Republican trifecta with a Senate supermajority, not just a simple House or Senate result.

The market runs through election day and may remain open longer if any runoff election could affect the final outcome. Resolution will rely on AP, Fox News, and NBC, with official certification used if those sources do not agree. Current market probability is about 9.8%, suggesting traders see the expected outcome as relatively unlikely, though not impossible. As an election forecast, it reflects broader market sentiment around the Trump-era Republican coalition, congressional control, and whether the party can secure enough Senate seats to reach the supermajority threshold.
