Risks

Trading on Outcome involves real risks. This page summarizes the most important ones, but it is not exhaustive. For the full picture, see Outcome’s Terms of Service. Because trades execute on Hyperliquid’s infrastructure, Hyperliquid’s Terms of Use and Risks page also apply.

​

Total loss of position

If your position resolves at 0, you lose the full amount you paid for it. There is no leverage and no liquidation, but “no liquidation” is not the same as “no risk.” Every position can settle at zero.

​

Smart contract and network risk

Outcome and Hyperliquid run on smart contracts and on Hyperliquid’s L1 blockchain. The Hyperliquid bridge contract has been audited by Zellic, but no audit eliminates risk entirely. Bugs or vulnerabilities anywhere along the path could result in loss of funds. The network may also experience downtime, which could prevent you from opening or closing positions while it lasts.

​

Interface availability

If outcome.xyz is unreachable (website issues, browser problems, general internet outages), your funds and positions are unaffected. They live on Hyperliquid, not on Outcome’s servers. You can close positions through any other interface that supports Hyperliquid’s HIP-4 markets while you wait for outcome.xyz to come back.

​

Oracle and settlement risk

Markets resolve based on the resolution terms defined in the market specification. Price-based markets settle against HyperCore mark prices, maintained by Hyperliquid validators. Event markets (sports, macro data, and similar) are resolved by the Hyperliquid validator set voting on the outcome. In both paths, settlement depends on the integrity of the resolution process: a compromised, manipulated, or stale price feed, or an incorrect validator resolution, could cause settlement to behave unexpectedly. For event markets specifically, outcomes that are ambiguous as worded carry more resolution uncertainty than deterministic price readings.

​

Liquidity risk

Spreads on Outcome can be wide in less active markets, and the order book may thin out further as a market approaches resolution. You may not be able to exit a position at a fair price (or at all) if there is no counterparty willing to take the other side. Prices can also move quickly near resolution as new information arrives.

​

Bridge risk

Deposits from other chains use Across, a third-party cross-chain bridge. Across has a strong track record, but bridges remain a higher-risk category in DeFi. A bridge failure would affect deposits in transit but would not affect funds already in your account on Hyperliquid.

​

Stablecoin risk

Outcome markets settle in USDC, issued by Circle. Like any stablecoin, USDC carries issuer, reserve, peg, and regulatory risks separate from the Hyperliquid protocol itself. Circle publishes regular attestations of USDC’s reserves, but no stablecoin is entirely without risk.

​

Geographic restrictions

Outcome is not available in some jurisdictions, including (but not limited to) the United States, certain Canadian provinces, and territories subject to international sanctions. For the complete list and your responsibilities as a user, see Outcome’s Terms of Service. Hyperliquid’s underlying protocol has its own restrictions; see Hyperliquid’s Terms. You are responsible for confirming you can lawfully use Outcome in your jurisdiction.

​

Regulatory uncertainty

Prediction markets are regulated differently across jurisdictions, and the regulatory environment is evolving. The treatment of outcome contracts for tax, securities, and derivatives purposes may not be settled in your jurisdiction. You should consider consulting a qualified advisor before trading at scale.
