Kalshi hits $100 billion in lifetime volume as settlement scrutiny rises
Kalshi crossed $100 billion in lifetime notional trading volume, driven largely by a surge in World Cup betting, the company said Friday, June 19. The milestone arrives alongside renewed scrutiny of how prediction markets settle contested outcomes, after a dispute over a Polymarket market on Iran reignited broader concerns about ambiguous event resolution. Kalshi's growth in sports and event contracts comes as institutional market makers deepen their presence in the sector and as rival platforms compete for the same retail and institutional flow. The settlement questions add a layer of operational risk to the industry's expansion into high-profile, politically sensitive markets.
Kalshi's $100 billion in notional volume now sits alongside an unresolved Iran market dispute on Polymarket that exposed how thin settlement governance remains for headline event contracts. If regulators or counterparties force stricter resolution standards, Kalshi's own World Cup and political markets face margin and trader-payout mechanics that are not yet stress-tested at this scale.
Kalshi's volume milestone lands as Robinhood tests Rothera for some World Cup contracts while keeping others on Kalshi, and as DRW, Wintermute, and IMC build prediction market desks for the same two platforms.
