Sleeper

Simplify's Take

What believers are saying

  • Best-ball, pick’em, and over-under formats extend engagement beyond season-long leagues.
  • Cross-sport products reduce NFL seasonality and broaden retention across the year.

What critics are saying

  • DraftKings and FanDuel bundle fantasy, DFS, and betting into a stronger habit loop.
  • Ad-free positioning weakens against aggressive deposit matches and promotional giveaways.[4][7]
  • Mobile distribution depends on App Store and Google Play policy compliance.[4][7]

What makes Sleeper unique

  • Ad-free fantasy app with in-app chat and live game context.[3][8]
  • Commissioners get unlimited pauses, undos, and pick changes during drafts.[1]

Sleeper integrates Kalshi prediction markets as platform hits $115B annualised volume

Kalshi, the world's largest prediction market, has partnered with sports app Sleeper to integrate prediction markets directly into its platform. Sleeper's 10 million users can now trade prediction markets on sports, with additional real-world event markets launching soon. The integration continues Kalshi's distribution strategy of powering prediction markets across platforms including Robinhood, Coinbase and PrizePicks. Annualised volume on Kalshi has crossed $115 billion, with Sunday's pro football championship market alone projected to exceed $800 million in trading volume. For Sleeper, the partnership expands user engagement beyond its fantasy leagues and daily fantasy sports offerings. The integration arrives ahead of the Super Bowl, allowing fans to participate in prediction markets where they already gather around sports.
