Safety check
Is Polymarket Safe & Legit?
Polymarket is the largest prediction market in the world, but its crypto-native, self-custody model works very differently from a regulated US brokerage. Here is what that means for safety.
In short: Polymarket is a legitimate, established platform — but its structure and crypto model shift more responsibility onto you than a dollar-based US exchange does.
Is Polymarket regulated?
Polymarket has a dual structure. Its largest exchange is domiciled offshore and states that it blocks US users; separately, Polymarket operates a CFTC-approved exchange for US customers. So a US trader uses the regulated US venue, while the much larger offshore pool is not intended for US access. This is an important distinction to understand before signing up.
How your money is held
Polymarket is crypto-native and self-custodied. You trade in the USDC stablecoin and your funds stay in your own wallet — Polymarket never holds your money. That is a genuine strength (you control your funds) and a genuine responsibility: if you lose your wallet keys or send funds on the wrong network, there is no support desk to recover them.
Who is behind Polymarket?
Polymarket is an independent company and the best-known name in the sector, with by far the deepest liquidity, particularly on politics and world events. It settles markets on-chain using an oracle system.
What to know before you deposit
- US traders should use Polymarket’s CFTC-approved US exchange; the large offshore exchange is not intended for US users.
- Self-custody means you are responsible for your own security — protect your wallet, and always confirm the token (USDC) and network before depositing.
- Markets resolve on-chain and can occasionally be disputed — see resolution sources and disputes, and check the wider legal position.
Polymarket is legitimate and the largest market there is, but it demands more of you: understand which exchange you are using and take responsibility for your own wallet security.
