Kalshi hit $3.9 billion in notional volume Saturday, with parlays topping 70%

Kalshi recorded $3.9 billion in notional trading volume on Saturday, according to data from TickerTracker. More than 70% of that volume came from parlays and combination bets. The figure underscores the platform's rapid growth in event-contract trading and the outsized role of multi-leg products in its current mix.

Shows parlay/combo products have become the dominant driver of Kalshi's volume, suggesting the platform's growth strategy is increasingly tied to complex bet structures rather than single-event contracts.
