Bottom line

Sleeper Markets is the most natural on-ramp to prediction markets for the 10 million users already on Sleeper's fantasy sports platform.

Launched in February 2026 via a partnership with Kalshi, it brings CFTC-regulated sports event contracts directly into the app where millions of fans already manage their fantasy leagues. The integration is the key differentiator: there is no new account to create, no new interface to learn, and no separate download. Fantasy sports players who follow injury reports, roster moves, and matchup data daily are exactly the kind of informed traders who have genuine edges in game-level prediction markets. The current limitation is category depth: Sleeper Markets is sports-only right now, with politics and other categories planned for later expansion.

Our Full Sleeper Markets Review

Written by Catie Di Stefano Β· Reviewed by PredictionRanks Editorial Team Β· Last reviewed August 25, 2026

Sleeper Markets launched in February 2026 inside the existing Sleeper fantasy sports app. Sleeper is approved as an NFA-registered Futures Commission Merchant (FCM) and routes orders through KalshiEX LLC as the Designated Contract Market.

Why It Matters

Ten million existing fantasy sports users now have one-tap access to CFTC-regulated event contracts inside the app they already use. There is no separate download, no new identity verification flow, and no need to learn a new interface. Sleeper's "Team Picks" tab is the prediction market product.

This audience is unusually well-suited to prediction market trading. Fantasy players already track injury reports, lineup confirmations, weather, and matchup data β€” the same inputs that drive game-level prediction market pricing.

Limitations

Sleeper Markets is sports-only. There is no politics, no macro, no crypto, and no entertainment category. The FCM structure also means Sleeper is one step removed from the exchange β€” order routing fees apply on top of Kalshi's spread.

What surprised us

The crossover between fantasy rosters and prediction contracts feels natural β€” pricing on player props is sharp because the fantasy user base brings real domain edge. Liquidity outside top NFL markets was thin during testing.

Frequently asked questions

Do I need a new account for Sleeper Markets?
No. If you already have a Sleeper account, you can access prediction markets directly in the app under "Team Picks." New users can download the Sleeper app and sign up.
How does Sleeper Markets differ from Sleeper Picks (DFS)?
Sleeper Picks is a daily fantasy sports product. Sleeper Markets (Team Picks) is a separate CFTC-regulated prediction market product where you buy and sell event contracts. They operate under different regulatory frameworks.
Is Sleeper Markets available in every state?
Yes. Sleeper Markets routes through Kalshi's CFTC Designated Contract Market under an NFA-approved Futures Commission Merchant (FCM) registration.
What sports can I trade on Sleeper Markets?
NFL, NBA, MLB, NHL, college football and college basketball, with player props and game-level outright winners. The catalog mirrors Sleeper's existing fantasy sport coverage.
What fees does Sleeper Markets charge?
Fees are bundled into the FCM routing spread on each trade. There is no separate commission or withdrawal fee. Effective costs are typically lower than a traditional sportsbook hold but slightly higher than direct Kalshi trading because of the FCM intermediation.
Can I use my fantasy balance for Team Picks?
No. Sleeper Picks (DFS) and Sleeper Markets run on separate wallets under different regulators. You'll need to fund Team Picks independently via the in-app deposit flow.
How long do withdrawals take?
ACH withdrawals to a linked US bank typically clear within 1–3 business days. The first withdrawal of any account will trigger an identity verification step that may add up to 24 hours.
