Prediction markets called Long Island congressional and New York governor races
Prediction markets accurately forecast the outcomes of four Long Island congressional races and New York's governor contest during the 2026 midterm elections, according to the South Shore Press. Traders on the platforms priced the results correctly. CoinDesk also examined whether prediction markets overall accurately called the full midterm cycle, which shifted control of both chambers of Congress in a high-turnout year. The assessments add to a broader post-election review of how crypto-native and regulated platforms performed against traditional polling.
Every mainstream accuracy test that holds up weakens the core claim in state gambling lawsuits against Kalshi and Polymarket. Attorneys general in Ohio and Tennessee argue event contracts amplify sentiment rather than predict outcomes; a correct call on specific races gives the platforms empirical ammunition ahead of likely 2027 proceedings. The South Shore Press validation joins CBS News assessments, a New York Times analysis of 428 races, and reported 96% favorite hit rates in building a peer-reviewed defense record.
Senators Warren and Curtis have already demanded internal trading data under bipartisan deadline, so each additional credible forecast enters the congressional record directly. State litigators can no longer dismiss accuracy as a talking point when multiple third-party audits now measure it race by race. The platforms' survival as regulated venues depends on proving forecasting utility, and each verified call tightens that argument.
