Prediction markets, where outcomes of real events are bet on, remain a reliable gauge of public sentiment. Despite a slight dip in trading volumes this week, the ecosystem demonstrated robust health with an 11% growth in open interest. Kalshi maintains its top position, while DeFi innovations hold potential to expand opportunities.
This week’s figures, compiled by analyst @Prithvir12, speak for themselves: Kalshi and Polymarket are crushing the competition, with nearly 5 million transactions each. Kalshi, in particular, is impressive, accounting alone for over 50% of the sector’s total open interest, which stands at $706 million. This dominance is explained by its status as a regulated platform in the United States (by the CFTC) and the diversity of its markets, ranging from politics to weather.
Polymarket, meanwhile, remains the king of the crypto and DeFi arena, with a massive user base of 248,000 people. The overall 7% growth in users across all platforms shows that the mainstream public is beginning to adopt these tools.

This week confirms it: prediction markets are no longer just a gimmick. They have become a “truth serum” for assessing the probabilities of future events, often outperforming traditional polls. With a leader like Kalshi gaining structure, and the arrival of innovations like leverage, the ecosystem is ready for a new acceleration phase. If the trend continues, open interest could well exceed one billion dollars by mid-2026.
