Hyperliquid Launches Prediction Markets on Real-World Events

• Hyperliquid launched real-world prediction markets without outside oracles.
• Validators now settle prediction markets directly through chain consensus.
• The first CPI prediction market crossed $11,000 in trading volume quickly.

Hyperliquid has added prediction markets based on real-world off-chain events directly into its core protocol, removing the need for external oracle systems that most competing platforms rely on.

The first market went live on Monday under the title ‘US May CPI Year-over-Year Growth’ and has already accumulated more than $11,000 in trading volume. It asks whether U.S. consumer price inflation for May will come in below a specific threshold, with settlement determined by official economic data.

The mechanism is built into Hyperliquid’s validator infrastructure rather than sitting on top of it. Automated newsfeed software run by validators as part of their regular node operations publishes the markets.

Those same validators then vote on whether a market should be deployed and how it should be settled, based on three criteria: whether the rules are clear and unambiguous, whether the outcome is verifiable, and the overall quality of the market.

Hyperliquid developer Yaugourt described the significance and said, “Hyperliquid just removed the need for external oracles on prediction markets. The validator set itself is now the oracle. Real-world event resolution is now a native chain function.”

Most prediction market platforms, including Polymarket, which suffered a $660,000 exploit earlier this week through its UMA adapter contract, rely on external oracle systems or separate dispute resolution mechanisms to verify real-world outcomes. Those external dependencies create both security risks and potential points of failure.

Hyperliquid’s approach embeds the resolution mechanism into the chain itself. Validators who already secure the network are responsible for determining market outcomes, making the process part of core protocol operations rather than an add-on layer.

The markets are fully collateralised contracts that settle within a fixed range and do not involve leverage or liquidations, keeping the risk profile straightforward for participants.

The launch builds on Hyperliquid’s HIP-4 upgrade, which expanded the platform beyond perpetual futures. Outcome markets went live on mainnet in a limited release on May 2.
