Kalshi nears $30 billion in monthly volume as World Cup drives record trading
Kalshi set a monthly trading record in June with volume nearing $30 billion, according to data cited by Allpaypayz. The 2026 FIFA World Cup was the primary driver. The figure builds on earlier growth: combined monthly volume on Kalshi and Polymarket climbed from under $5 billion last September to roughly $24 billion by April, per Fat Tail Daily. The surge puts both platforms through their highest-stakes liquidity test yet as the tournament advances.
The $30 billion figure resets what regulators and investors consider normal for event-contract markets. Kalshi needs clean settlement and tight spreads to justify the DRW, Wintermute, and IMC market-making commitments already in place.
A clean tournament opens the NFL and Olympics as next verticals. A settlement failure or fraud case gives state attorneys general concrete evidence that these contracts are gambling instruments, not derivatives.
