What Sleeper does

Sleeper, operated by Blitz Studios, Inc., is a mobile-first fantasy sports platform serving more than 10 million registered users across the United States and Canada. Its core product surface spans traditional season-long fantasy leagues (Fantasy Football in Dynasty, Redraft, and Keeper formats; Fantasy Basketball; Fantasy Soccer for EPL and LaLiga) alongside a growing set of social game formats — PICKS pick'em with up to 1000x payouts, Chopped Leagues weekly-elimination play, Bracket Mania, Football Survivor, and Football Pick'em. The platform runs as native iOS and Android applications plus a web client, and exposes a free read-only developer API at docs.sleeper.app.

Monetization is layered: Sleeper operates free leagues as a funnel, then captures transaction-fee revenue from paid-entry daily fantasy contests (operated as contests of skill), PICKS entries, and prediction market contracts. The prediction market offering, launched in February 2026, routes through Sleeper Markets LLC — a CFTC-registered Futures Commission Merchant and KalshiEX member — charging $0.02 per executed contract. Supporting infrastructure includes Sleeper Wallet (bank/ACH/card and crypto on-ramp via Zero Hash), SleeperSafe for league-dues management, and integrations with Kalshi and Zero Hash. Distribution is product-led and community-led, with no enterprise sales motion; growth relies on word-of-mouth, organic social (Reddit, X, Facebook, Instagram), app store optimization, affiliate promotional codes, creator partnerships including Hog Media, and brand advertising (e.g., a prior Super Bowl spot). The company is VC-backed (notably Andreessen Horowitz across Series B and C) and continues to operate as a private company with multiple regulated subsidiaries.

Direct peers

• Polymarket: Prediction market platform where users trade on event outcomes (sports, politics, current events). Closely comparable to Sleeper's Kalshi-powered prediction markets product, with the key difference that Polymarket is crypto-based and Sleeper is CFTC-regulated fiat.
• Underdog Fantasy: DFS operator offering pick'em and best-ball fantasy formats with a mobile-first approach. Closely comparable to Sleeper in product philosophy and target demographic (mobile, social, friend-league play), with newer prediction market exposure.
• PrizePicks: Pick'em fantasy operator where users select player props across multiple sports. Direct peer to Sleeper's PICKS product with similar mechanics and payout structures, though PrizePicks has historically focused more on individual player props than team-based outcomes.

Broad incumbents

• CBS Sports Fantasy: Long-running season-long fantasy sports platform from CBS Sports. Competes with Sleeper on Dynasty and Redraft formats across NFL, NBA, and MLB, leveraging CBS's broadcast media for audience reach.
• FanDuel: Flutter-owned DFS and sportsbook operator that is the leading U.S. daily fantasy sports competitor. Competes with Sleeper on paid-entry NFL/NBA contests and offers similar season-long and pick'em formats, with substantially more state coverage and capital.
• DraftKings: Public DFS and online sports betting operator offering daily fantasy contests, sportsbook, and prediction market products. Direct DFS competitor to Sleeper across NFL, NBA, MLB, and soccer, with significantly larger scale, brand, and regulatory footprint.
• Yahoo Fantasy: Long-standing season-long fantasy sports platform integrated with Yahoo Sports. Competes with Sleeper on Dynasty/Redraft/Keeper formats across NFL, NBA, MLB, and NHL, with a free-to-play model that overlaps Sleeper's freemium core.
• ESPN Fantasy: Disney/ESPN-owned fantasy sports platform with broad season-long coverage across major U.S. leagues. Comparable to Sleeper on traditional fantasy league formats, leveraging ESPN's media reach for organic user acquisition.

Emerging players

• OwnersBox: DFS operator focused on peer-to-peer contests and simplified mobile UX. Comparable to Sleeper in its social, mobile-first design philosophy and emphasis on friend-league dynamics in paid contests.
• Betr: Pick'em and micro-betting operator with a mobile-first product targeting younger sports fans. Overlaps with Sleeper on PICKS-style pick'em mechanics and prediction market-style offerings, though with a sportsbook emphasis.
