Midterm trading volumes reveal wide gap between ForecastEx and Kalshi
CNN reports ForecastEx, owned by Interactive Brokers, has generated more than 6.4 million dollars in trading volume on markets about the midterms. PredictIt, operating since 2014, declined to disclose its midterm figures, while Kalshi covers race outcomes, turnout numbers, endorsements and debate markets within its near 1.1 billion dollars of midterm volume.
CNN reports that ForecastEx, owned by Interactive Brokers, has recorded more than 6.4 million dollars in trading volume across markets tied to the midterms. That puts its reported activity well below Kalshi’s near 1.1 billion dollars in midterm volume.
Reported volumes and market coverage
Kalshi’s midterm markets span race outcomes, turnout numbers, endorsements and debates, according to CNN. Its reported volume therefore covers more than trading on which candidates will win.
PredictIt, which has operated since 2014, declined to disclose its midterm figures, CNN reports. That leaves one venue’s activity unavailable for comparison with the disclosed totals.
The figures show a substantial difference in reported trading volume between ForecastEx and Kalshi. Without PredictIt’s figures or a total covering all venues, however, they do not establish each platform’s share of the overall midterm market.
What it means for prediction markets
- Reported activity differs sharply by venue: ForecastEx’s more than 6.4 million dollars sits far below Kalshi’s near 1.1 billion dollars.
- Market scope matters: Kalshi’s aggregate includes turnout, endorsement and debate markets alongside race outcomes; it is not solely a measure of election-winner trading.
- The comparison remains incomplete: PredictIt’s decision not to disclose its midterm volume limits conclusions about the distribution of trading across platforms.
