No — there are no margin calls, no leverage, and no stop-outs beyond your entry cost. Your maximum loss is what you paid. But there are 3 risk scenarios most guides don't mention. Read those before you trade.
Short Answer: No, you cannot lose more than you stake.
Prediction market contracts are binary — you pay some amount, and the outcome is either a win (resolve to $1.00) or a loss (resolve to $0). There are no margin calls, no borrowed funds, and no leveraged exposure.
BUT: There are 3 risk scenarios most guides gloss over — USDC stablecoin volatility, smart contract custody, and oracle dispute edge cases. They don't change the loss cap, but they affect what you actually get back.
| Feature | Kalshi | Polymarket |
|---|---|---|
| Regulator | CFTC (DCM + DCO) | CFTC via QCX LLC (DCM) |
| Account currency | USD (cash account) | USDC stablecoin (or USD via card) |
| Maximum loss | Your stake only | Your stake only* |
| Margin / leverage | None | None |
| Fund custody | Segregated cash accounts | Smart contract (Polygon blockchain) |
| FDIC insured | No | No |
* 3 edge cases apply to Polymarket — see below
These are real. They don't change the maximum loss ceiling, but they affect the quality and timing of what you get back. Polymarket-specific risks are noted.
Kalshi is a CFTC-registered DCO (Derivatives Clearing Organization). Customer funds are required by regulation to be segregated from Kalshi's operating funds. In an insolvency, segregated customer funds cannot be used to pay Kalshi's creditors — unlike a regular corporate bankruptcy.
Important caveat: This is regulatory protection, not FDIC insurance. Customer funds are NOT insured up to $250,000 like a bank account. DCO segregation means creditors can't touch them — but if funds were mishandled before being placed into segregation, recovery is not guaranteed.
Can you lose MORE than you bet? No — no margin, no leverage, no stop-outs.
Is Kalshi safer from custody risk? Yes — cash accounts + DCO segregation rules vs smart contracts.
Can you lose your entire stake? Yes, if you bet wrong and the contract resolves against you.
Is USDC the same as USD? Usually — but not always. USDC depegged briefly in 2023. Neither platform is FDIC-insured.
