Prediction markets win big on election night
Kalshi and Polymarket correctly called the Democratic sweep of Congress by wider margins than most polling models, as well as some key battleground races.
In the recent midterms, prediction markets proved to be formidable competitors. Kalshi and Polymarket accurately predicted the Democratic landslide in Congress, along with crucial swing state outcomes, surpassing many polling models in their accuracy. However, they fell short in forecasting unexpected results such as Texas Governor Greg Abbott's defeat and Democratic wins in Iowa and South Carolina.
Trading activity on election-related contracts surged nearly fivefold, reaching $1.8 billion during this year's midterms, compared to the 2024 cycle. Contrary to other popular betting categories, sports and cryptocurrency markets still dominate trading volume on these platforms. Polymarket and Kalshi, two leading prediction markets, have heavily invested in advertising to attract the sports-betting and gambling crowd, with aggressive campaigns on Meta and surpassing super PAC spending levels.
Strategic partnerships with media outlets like CNN and Dow Jones have also bolstered their influence.
While these firms have undoubtedly increased their revenue, the true test of their success lies in their ability to deliver accurate predictions - a feat prediction markets claim to excel at.
