Parlays Push Kalshi Past $3.9 Billion in a Day, Twice in a Weekend

Kalshi set back-to-back daily volume records over the weekend, at $3.91 billion on Saturday and $3.96 billion on Sunday. Parlay-style combos made up about 70% of both days, most of them long shots priced below 1 cent. Kalshi’s daily market data , which runs on U.S. Eastern days, shows $3.91 billion in notional volume on Saturday, Oct. 10, and $3.96 billion on Sunday, Oct. 11, both above the previous high of $3.68 billion set on Sunday, Oct. 4. Notional volume counts each contract at its full $1 payout, which the buyer and seller fund between them according to the price.
