Kalshi Election Day Volume Hits $4.15B, Short of Its October Record

Kalshi recorded $4.15 billion in notional volume on Election Day, Nov. 3, its largest weekday total but below the $5.3 billion single-day record set Saturday, Oct. 24. Single-market contracts drove the activity as parlay-style combos fell to 58.6% of volume from roughly three-quarters on the record day. The split matters because it shows demand shifting toward simpler, single-event bets rather than multi-leg combos that inflated the October peak. Kalshi’s next test is whether single-market contracts can sustain volume without combo-driven spikes.
