Hyperliquid launched its first US macro event market, a CPI outcome contract letting traders bet USDC on the May 2026 year-over-year inflation print, settling on June 10 using official Bureau of Labor Statistics data.

Zero fees to open HIP-4 positions; fees only apply on close, burn, or settlement. All contracts fully collateralized in USDH; no liquidation risk, no leverage.

Hyperliquid activated HIP-4 Outcome Markets on mainnet on May 2, bringing collateralized prediction contracts directly into the same account where traders run perpetual futures & spot positions.
