Promote with Leviathan Newsa16z crypto says Kalshi and Polymarket cleared $3.6B of non-sports prediction-market volume last week across politics, economics, geopolitics, and current events. That category was around $200M per week in July 2025, so the move is roughly 18x in under a year. World Cup markets may be sucking oxygen, but the sharper signal is that non-sports prediction markets are turning into the real growth engine.
