Prediction markets draw six-figure wagers on Connecticut and Kansas primaries
Prediction markets attracted more than $100,000 in wagers on Connecticut primary elections, NHPR reported. The activity concentrated on Kalshi and Polymarket, which have seen popularity grow over the last two years. Separately, the Republican gubernatorial primary in Kansas drew roughly $140,000 in wagers on Kalshi, making it the most expensive race on that platform. Bettors on Polymarket also concentrated activity on the Kansas contest.
These primary volumes test whether election betting can sustain liquidity outside the highest-profile races. Kalshi, the $140,000 Kansas race shows its midterms hub can attract meaningful flow beyond presidential markets. The Connecticut tally, spread across multiple contests, suggests narrower races may not concentrate enough volume for tight spreads.
Traders face a venue choice: Kalshi's thinner books may offer worse prices but avoid Polymarket's concentration risk. Election Day is roughly 90 days away. Platforms need to prove political contracts work in off-cycle primaries or risk losing traders to general-election slates alone. Campaigns and journalists already treat these prices as sentiment gauges, so liquidity gaps damage credibility for both venues.
