Our ProphetX review

ProphetX is the platform I now open first when I want a sports position from California. It is a sports-first prediction market: NFL, NBA, MLB, NHL, college football, soccer and fight nights; check the app for other markets. That focus is the point. Everything in the app is built around game day rather than a general-purpose event exchange.

The important change in 2026 is regulatory. ProphetX retired its old sweepstakes product and now runs as a CFTC-designated contract market that accepts California residents. You deposit US dollars, you trade contracts against other traders, and payouts settle from the exchange rather than from a house that sets the price.

What that peer-to-peer structure means in practice: you are trading with other people, so the price you pay is the price the market agreed on. The tradeoff is coverage. If you want political or cultural markets, you still need Polymarket or Kalshi alongside it.

Is ProphetX legit and legal in California?

ProphetX is a CFTC-designated contract market (designated June 11, 2026), which puts it under the same federal framework as other regulated derivatives venues. It accepts California residents, and its status here is Available, dispute pending (as of October 13, 2026), because courts bound by the Ninth Circuit are still deciding whether state gambling law covers sports contracts.

Because the contracts are federally regulated derivatives rather than state-licensed sports betting, ProphetX does not depend on California passing a sports-betting law. That is the same legal basis Kalshi and Polymarket rely on in the state.

ProphetX LLC is a CFTC-designated contract market, so the federal regulator supervises it. Trading is still risky and you can lose what you put in. If you previously used ProphetX under its sweepstakes model, the account experience is different now: real deposits, real contracts, real settlement.

What is ProphetX?

ProphetX is a CFTC-designated contract market (designated June 11, 2026) for sports event contracts, where you trade against other people.

Is ProphetX legal in California?

Status: Available, dispute pending (as of October 13, 2026). ProphetX accepts California residents. California has taken no enforcement action against the platforms, but Kalshi has switched off its markets on three tribes' lands after a 16 Sep 2026 Ninth Circuit ruling, and the Ninth Circuit's 28 Aug 2026 Nevada ruling binds California's federal courts. The status describes access to the platform, not a court ruling on legality.

That said, the legal picture is still being contested. Some state attorneys general have challenged certain platforms; the CFTC has consistently defended its jurisdiction. For the full backdrop, see our California legality guide.

What can you trade on ProphetX?

ProphetX covers Sports, Peer-to-peer, NFL, NBA. New markets are added weekly.

Practically, that means contracts on game outcomes, championship futures, and player and team milestones. ProphetX is built around sports: NFL, NBA, MLB, NHL, college sports, soccer and more.

How does ProphetX work?

Every contract on ProphetX settles at $1 (yes) or $0 (no). The price you pay reflects the market's implied probability. Example: a contract priced at 62¢ would imply a 62% chance.

You don't have to hold a contract until it settles; you can sell at any time. Example: if you bought at 62¢ and the price later moved to 78¢, you could sell and keep the difference, before fees. You are trading a price, which is different from placing a bet with a sportsbook. For the full mechanic, read how event contracts work.

How much does ProphetX charge?

ProphetX charges 2% of your net winnings per market on straight trades. On parlays, only the taker pays a fee set by ProphetX's parlay fee schedule (version 1.3, October 12, 2026), with a 1-cent minimum per order. (Checked October 14, 2026.)

Liquidity varies by market. High-profile events like playoff series are deep, while niche markets can be thin. Always check the bid-ask spread before taking a position.

ProphetX fees and payments

ProphetX is a peer-to-peer exchange, so the cost model looks more like a trading venue than a sportsbook. Here is what you actually pay as a US trader in 2026:

Fee schedules change. Confirm the current numbers inside the app before you size up a position.

Is ProphetX safe?

ProphetX LLC is a CFTC-designated contract market, so the federal regulator supervises it. Trading is still risky and you can lose what you put in.

That regulatory backstop is the single biggest reason California traders choose CFTC-regulated venues over offshore sportsbooks, which operate outside U.S. consumer protection.

Who should use ProphetX?

ProphetX is best for sports-only traders, peer-to-peer pricing, and california residents who want a sports-native exchange.

If that profile fits you, ProphetX is worth a look: we rate it 4.7 out of 5.

Who should not use ProphetX?

ProphetX is not ideal for politics and election traders or culture and awards markets or macro and economics markets.

If that's you, browse our full platform rankings for a better fit.

ProphetX and Kalshi are both CFTC-regulated event-contract venues, but they target different traders. See our full ProphetX vs Kalshi comparison.
