Crypto.com prediction markets and Coinbase prediction markets both serve US customers — but neither runs them the way Polymarket does. They plug event contracts into their existing apps, using a regulated US exchange behind the scenes.
Coinbase prediction markets
- What: event contracts on sports, politics, economics and more, inside the Coinbase app.
- Who runs the market: contracts are provided through Coinbase's partnership with Kalshi, a CFTC-designated contract market.
- When: rolling out from December 2025, and live in all 50 states from January 2026, with trades from $1.
- Currency: USD or USDC in your Coinbase account.
Coinbase prediction markets review: pros and cons
Pros: easy if you already use Coinbase; regulated exchange behind it. Cons: you're trading Kalshi's contracts through another app, so check which fees apply on top — Coinbase's own and the exchange's.
Crypto.com prediction markets
- What: event contracts, with a strong focus on sports.
- Who runs the market: Crypto.com | Derivatives North America (CDNA), Crypto.com's CFTC-registered derivatives exchange and clearinghouse.
- Where: US customers, subject to state disputes over sports contracts.
Pros and cons
Pros: integrated in the Crypto.com app; its own regulated venue. Cons: sports contracts are at the centre of state legal challenges, and availability can change by state.
How event contracts work on these apps
The mechanics are the same as on any prediction market: a YES contract pays $1 if the event happens and $0 if not, and the price in cents reads as a probability. See event contract and implied probability.

Brokers and exchanges add convenience; dedicated exchanges usually offer more markets and deeper books. Before choosing, compare the fee on the order screen and the liquidity of the specific market.
Things to check before trading
- Fees — the app's fee plus any exchange fee.
- Liquidity — a thin market can cost more in slippage than in fees.
- Rules — each contract's resolution source and deadline.
- Your state — sports contracts in particular face legal challenges; see Polymarket legal states.
