Kalshi retains weekend volume lead as trading falls across platforms
Covers reports Kalshi accounted for 74 percent of the Saturday-Sunday volume reported to Aldrin Research, with its 9.44 billion dollar total down from 10.06 billion dollars the prior weekend, sports taking 846.5 million dollars on Saturday and a 2.7 percent week-over-week dip on NFL Sunday. Polymarket U.S. Saturday volume fell 17.5 percent to 669.3 million dollars, while DraftKings Predictions Sunday volume fell 8.5 percent to 363 million dollars.
Kalshi recorded $9.44 billion in weekend notional volume, a decline of 6.2 percent from $10.06 billion the previous weekend, according to Covers. Despite the decrease, it represented 74 percent of the Saturday-Sunday volume reported to Aldrin Research.
Kalshi’s sports activity
Sports accounted for $846.5 million in Kalshi volume on Saturday, Covers reported. Its NFL Sunday volume declined 2.7 percent week over week.
Eagles-Commanders was Kalshi’s most-traded game, generating $96.2 million in volume, according to Covers. The game-level figure provides a narrower view of activity than the platform’s overall weekend notional total.
Other platforms also post declines
Polymarket U.S. recorded $669.3 million in Saturday volume, down 17.5 percent, according to Covers. DraftKings Predictions reported Sunday volume of $363 million, a decrease of 8.5 percent.
Those figures cover different days and should not be treated as a like-for-like weekend comparison. Kalshi’s 74 percent share applies specifically to the Saturday-Sunday volume reported to Aldrin Research.
What it means for prediction markets
- Kalshi maintained the largest reported share: Its 74 percent contribution to the reported weekend total accompanied a 6.2 percent decline in its own notional volume.
- The comparison windows matter: Polymarket U.S.’s Saturday figure and DraftKings Predictions’ Sunday figure do not establish either platform’s full-weekend performance.
- Volume is not an odds signal: These figures describe trading activity, not changes in implied probabilities or the likelihood of particular game outcomes.
