Prediction markets outperformed preelection polls in 2024 presidential race
Prediction markets offered more accurate forecasts of the 2024 US presidential election than traditional preelection polls, according to analysis published ahead of the 2026 midterms. Polymarket and Kalshi both correctly predicted Trump's victory while polls struggled. The commentary notes that pollsters now face a more difficult environment as prediction markets demonstrated less reliance on polling data during the last presidential cycle.
The accuracy gap strips credibility from a polling industry that still commands premium fees from media outlets and campaigns. For Polymarket and Kalshi, the 2024 result is a permanent marketing asset they can deploy every election cycle. Campaign strategists and newsrooms must now justify spending on polls when free market prices update continuously and have a demonstrable track record.
The shift threatens the business model of established pollsters who sell to both sides of the aisle. If prediction markets repeat their performance in the 2026 midterms, political media will face pressure to cite market prices alongside or above poll averages. That would drive traffic to regulated platforms and force pollsters to prove their value with narrower, issue-specific surveys rather than horse-race headlines.
The idea that prediction markets bested traditional polling in 2024 presidential forecasting has moved from academic claim to bank workflow, as SocGen's midterm forecast incorporates Kalshi and Polymarket pricing alongside traditional data sources.
