Checked 12 Nov 2026, Sleeper says Picks is available in most US states but publishes no fee formula, while Novig charges takers 0.06 x P x (1 - P), only in-game on game markets. (Source: [Sleeper: Picks](https://sleeper.com/picks)) Sleeper is best known for season-long fantasy leagues. It added Sleeper Picks, a pick'em contest, and Sleeper Markets, where team picks trade as event contracts inside the same app. Novig is a standalone exchange with a published fee schedule. ## Fees Fees, checked 12 Nov 2026 | Fees (checked 12 Nov 2026) | Novig | Sleeper | | --- | --- | --- | | How you pay | Taker pays 0.06 x P x (1 - P) per $1 of payout; makers pay nothing | Not published as a formula; payouts set in the app | | When it applies | Game markets: only while the event is live.

Its daily CSVs list every trade, and [novigapi.com](https://novigapi.com/novig-api) joins player names to each market and keeps intraday line history. ## Pick'em versus a priced market A pick'em contest pays a set multiple when your picks hit; you never see the price on the other side. An exchange shows both sides as probabilities you can trade at, so the cost is the spread plus the fee. Novig's own worked examples, per $100 of payout at the 0.06 coefficient: $1.50 at 50%, $1.26 at 30% or 70%, and $0.54 at 10%. The fee is charged to five decimal places with no cent floor, and a pregame fill on a game market owes nothing. That difference matters for anyone who wants to measure value. With exchange prices you can compute a no-vig fair probability and compare it to your own projection; with fixed pick'em payouts you can only work back to an implied break-even rate.

Eligibility differs too. Novig requires 21 or older, identity verification and a physical location outside Nevada, Arizona and Michigan, checked each time you open the app to trade. Sleeper's pick'em and markets follow their own state lists, which Sleeper describes only as most US states for Picks. Check the app's own state screen before you deposit. ## Verdict Sleeper is a social fantasy product; Novig is a priced market. For a transparent cost and usable data, Novig is the stronger choice; for leagues with friends, Sleeper is. ## Questions ### Where is Sleeper Picks available?
