Sportsbooks, exchanges & leagues we cover

What SmartStake connects to

SmartStake reads prices and lines from sportsbooks, exchanges, prediction markets, and DFS sites. Each source type plays a different role in the tools. The in-app book list reflects the sources currently available to your account.

Coverage additions in the Fantasy 2.0 update include Chalkboard, JustBet, ComeOn, Betinia, BetFair, and STX. League coverage also includes NHL preseason. Available events and markets vary by source.

Sportsbooks

The majority of sources are traditional sportsbooks — the books where you hold accounts and place bets. These are the prices the Positive EV and Arbitrage tools compare against the fair no-vig price. Having accounts spread across many books is the practical foundation of line shopping: the wider your coverage, the more opportunities you can actually act on. The full book list is available to Premium subscribers; without a subscription you see a limited subset. See Choosing your sportsbooks for guidance on which books matter most for each tool.

A reference selection of sharp books supplies prices for Positive EV's fair-value comparisons, and you can configure that selection. Fantasy's Default model uses its own reference pool; Custom uses books you select. See Sharp books and Fantasy model settings.

Betting exchanges

SmartStake tracks order-book depth across 6 betting exchanges. Unlike a sportsbook, an exchange matches bettors against each other, so the volume and price at each side of the book reflects genuine market activity rather than a book setting a line. This depth data is the raw signal behind the Smart Money tool: when exchange liquidity moves sharply on one side, that is the signal Smart Money surfaces. The default liquidity floor is $200 — bets with less depth than that threshold are filtered out before the signal is computed.

Prediction markets

Polymarket and Kalshi are prediction markets where participants trade on event outcomes using real money. SmartStake tracks qualified wallets on these platforms and uses their trading history to populate the Insiders feed. A wallet qualifies when it meets a minimum activity bar — at least 200 sports markets traded, a positive ROI, and an arbitrage ratio that rules out pure cross-market hedging — so the feed reflects wallets with a genuine track record, not random accounts.

DFS pick'em sites

DFS pick'em sites let you build multi-leg slips using Power or Flex payout structures. SmartStake's Fantasy optimizer compares picks with the SmartStake Line or your Custom model, including supported differences between Fantasy and sportsbook lines.

Covered platforms include Chalkboard, PrizePicks, Underdog Fantasy, Betr, Dabble, DraftKings Pick6, Splash Sports, and Bleacher Nation Pick6, among others. Platform availability does not mean every market or slip format is supported.

Leagues we cover

SmartStake covers major sports and esports. The league list changes as seasons open and close, so not every league appears year-round. Use the league filter in your chosen tool to see its current coverage.

American sports

The core of the coverage is North American professional and college sport: NFL, NBA, MLB, NHL, NCAAF, NCAAB, WNBA, and MLS. These leagues have the deepest book coverage and the most liquid exchange markets, which means sharper fair prices and more opportunities across all the tools.

NHL preseason is included when participating sources offer those events. Preseason coverage depends on the lines and markets available from each source.

Soccer

Coverage extends across the major European competitions — the Premier League, UEFA Champions League, UEFA Europa League, Bundesliga, La Liga, Serie A, and Ligue 1 — as well as international competitions and additional domestic leagues. The exact set active at any moment reflects which competitions are in season.

Other sports

Tennis (ATP and WTA), MMA (UFC and others), and boxing round out the coverage alongside the North American and soccer leagues.

Esports

SmartStake covers esports markets including CS2, Valorant, League of Legends, Dota 2, and related tournaments. Exchange and prediction-market coverage for esports is thinner than for major North American sports, so Smart Money and Insiders signals are less common in this category.
