Robinhood’s launch of Kalshi parlays has helped turn them into a serious part of Kalshi’s business, with combo bets making more money in fees for the exchange last Sunday than non-sports events have ever made in a single day.
Parlays are still a dramatically smaller portion of Kalshi’s business than they are for leading sportsbooks. However, they have gone from a fringe item to a significant contributor to the exchange’s overall fee revenue on the days of major NFL games.
The day of the conference championship games set new records for overall volume and fee revenue on Kalshi, based on InGame’s analysis of Kalshi’s fees. Users traded $543.1 million worth of contracts in total and the exchange made $5.46 million worth of fees. Of that volume figure, $505.8 million, or 93%, was on sports.
