Prediction markets are hitting mainstream scale. Kalshi just recorded $837.1 million in trading volume over the weekend—marking a new peak. The momentum was fueled primarily by NFL Playoff betting action.

Meanwhile, Polymarket's numbers also jumped significantly in the same window, with sports predictions making up roughly 55% of its total activity.

The spike tells an interesting story: when major events hit the calendar, prediction market infrastructure actually shows up. It's not just niche speculation anymore—real volume, real participation. Whether this momentum sticks around remains to be seen, but the data suggests these platforms are finally getting the kind of traction they've been chasing for years.
