Polymarket trader 0xA2 topped the platform’s daily profit leaderboard at $917,000 after Democrats took control of both chambers of Congress in the 2026 U.S. midterms. Most of that profit was unrealized: a $609,644 bet that Republicans would win no Senate swing states was valued at $1.48 million, but the market remained open pending Alaska’s final result. Polymarket traders gave an Alaska upset a 14% chance, so the position’s roughly $860,000 gain could still change.
