Legality in California

Markets and coverage

Chalkboard specializes in player props, picks on individual player performance, with the deepest coverage in the NBA and NFL. Sleeper's player prop coverage is growing but significantly narrower than Chalkboard's.

User experience

Who should use which

Sleeper is a fantasy and pick'em app built around game-level picks, fantasy leagues and a social layer. Chalkboard is a pick'em-style player-prop app for people who follow individual athletes more than team outcomes. Neither is a CFTC-regulated exchange. California readers who want one should use ProphetX for sports, or Kalshi for a broader mix of markets.

How we rank

The ranking comes from the scorecard on our methodology page. Each platform is scored on five things:

• Regulation and California availability (25%): who regulates the platform and whether California residents can open an account.
• Fees and order fills (25%): trading, deposit and withdrawal fees, and how our test orders were filled.
• Market range and liquidity (20%): how many markets are live and how much trading there is on the main contracts.
• Deposits and withdrawals (15%): which payment methods work and how long the money takes to arrive.
• App quality and support (15%): app stability, the website, and how support answered a test request.

The sign-up offer is shown for each platform but is not part of the score.

Tested by Catie Di Stefano, who opens an account, deposits our own money, places trades and withdraws. The full process is on our methodology page.
