Before naming a Sleeper alternative, it helps to remember Sleeper isn’t one product wearing one login. Sleeper Picks is pick-em daily fantasy sports. Sleeper Markets, added in 2026, trades sports event contracts through Kalshi under a separate federal approval. They fail for different reasons in different states, so the app that actually replaces whichever one just went dark depends on reading the fine print first.
Lost Access to Sleeper Picks: Try PrizePicks or Underdog
For the DFS pick-em format specifically — build a lineup against player projection lines, no sportsbook license required — PrizePicks and Underdog are the direct matches. Both operate under the same style of fantasy-sports carve-out Sleeper Picks uses, and both maintain their own paid-entry state lists that don’t track Sleeper’s roughly 20-state block list. A state where Sleeper Picks is closed can still have PrizePicks or Underdog open, and the reverse happens too.
Underdog runs a second product. Alongside its DFS pick’em contests, Underdog offers Pick’em Champions, a peer-to-peer format licensed state by state starting with New Jersey and Delaware — a narrower footprint than its DFS side, worth checking separately.
Lost Access to Sleeper Markets: Try Kalshi or Polymarket US
Sleeper Markets isn’t its own exchange — it’s an NFA-approved Futures Commission Merchant that routes sports event contract trades onto Kalshi’s CFTC-designated market. That means a state order aimed at Kalshi’s sports contracts reaches Sleeper Markets the same way; picking a different front-end doesn’t dodge it. Polymarket US, run by QCX LLC and relaunched in December 2025, is a genuinely separate company sitting in the same state-versus-CFTC dispute, not a cleaner alternative to it.
Wanted a Real Sportsbook the Whole Time?
Some of this search traffic is someone who wanted to bet a moneyline or a spread against a book and ended up on a fantasy or contracts app instead. Neither half of Sleeper was built for that. Where a state has actually licensed online sports betting, DraftKings and FanDuel are the real comparison — a state gaming license and published odds, a different regulatory category from either DFS or an event contract.
Replaces Sleeper Picks: PrizePicks, Underdog — check each state list on its own.
Replaces Sleeper Markets: Kalshi, Polymarket US — same legal exposure, different company.
Wanted a licensed book: DraftKings, FanDuel — only where actually live.
Check the State Map Before You Switch
Swapping apps doesn’t swap the law underneath them. A state that blocked Sleeper Picks’ paid entries can block the identical format on PrizePicks or Underdog for the same reason, and a state fighting Kalshi over sports contracts can extend that fight to Sleeper Markets or Polymarket US next. None of these five apps is a way to make money — confirm current eligibility on the operator’s own site before funding any of them.
