Weekend volume breakdown widens beyond Kalshi: Polymarket US second, DraftKings third on Sunday

New operator detail behind the weekend record: Polymarket US cleared about $1.18B over Saturday–Sunday, up 13.2% on the prior weekend, while Sunday alone put DraftKings…

Polymarket US recorded about $1.18B in notional trading volume across Saturday and Sunday, an increase of 13.2% from the previous weekend, according to Covers. The operator-level figures add detail to a record weekend for prediction-market activity.

Volume beyond the leader

Across the industry, weekend notional volume exceeded $10.5 billion during NFL Week 5, Covers reported. Kalshi led operators with $7.87 billion, remaining well ahead of Polymarket US despite the latter’s weekend growth.

Sunday’s rankings placed Polymarket US second and DraftKings third. That daily ordering provides a separate view of competition from the Saturday–Sunday totals: DraftKings’ third-place position applies specifically to Sunday.

The supplied report does not include DraftKings’ Sunday volume or a complete operator breakdown. It therefore establishes the reported daily ranking, but does not quantify the gap between DraftKings and Polymarket US that day.

What it means for prediction markets

  • Kalshi remained the volume leader: Its $7.87 billion weekend total dominated the reported industry activity.
  • Polymarket US showed weekend growth: About $1.18B in volume represented a 13.2% increase over the prior weekend.
  • Comparison periods matter: Sunday’s second- and third-place rankings should be kept distinct from full-weekend volume figures.
