Legality in California

Novig, a peer-to-peer sports exchange, accepts California residents 21+ (it is not available in Arizona, Michigan or Nevada). Sleeper runs fantasy and pick'em games under different rules, so check the Sleeper app for what is available in California.

Markets and coverage

Sleeper covers NFL, NBA, MLB, NHL, soccer (including World Cup 2026), and select cultural markets, broad sports coverage anchored to fantasy. Novig is sports-focused too, NFL, NBA, MLB, NHL, college, soccer, tennis and golf majors, with an exchange-style order book. Neither covers politics or macro; for that, Kalshi is required.

Pricing & fees

Novig's peer-to-peer structure often produces tighter prices on liquid sports markets: no house margin, just bid-ask spreads. Sleeper is a fantasy and pick'em app, not an exchange, so check the Sleeper app for its costs and terms. Novig charges a small fee disclosed at order entry.

User experience

Sleeper's interface is built for fantasy users: your league, draft, chat, and picks in one app. Novig's interface is built for traders: visible order books, limit orders, bid-ask spreads. Sleeper is friendlier for casuals; Novig rewards traders who understand exchange mechanics.

Who should use which

Use ProphetX if: you only trade sports and want a CFTC-licensed exchange with peer-to-peer pricing, or Kalshi if you're a beginner or want a broader mix. Use Novig if: you're an experienced sports trader, you've been limited or banned by sportsbooks, you want the tightest pricing on high-liquidity markets. Sleeper is a fantasy and pick'em app, not a CFTC-regulated exchange; check the Sleeper app for what it offers in California.

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.
