Hyperliquid launches fully‑collateralized US CPI markets under HIP‑4 with validator‑governed outcomes

Hyperliquid has launched CPI prediction markets using its HIP‑4 outcome contracts, offering fully collateralized, USDC‑denominated bets on the May 2026 US CPI year‑over‑year print; the contracts are structured with no liquidations and are scheduled to settle on June 10, 2026 ^{[1] [2]}.

The rollout expands Hyperliquid’s L1 derivatives product suite into on‑chain macroeconomic prediction markets and positions the platform as a direct competitor to Polymarket. Hyperliquid’s HIP‑4 update also introduces validator‑governed outcome markets for off‑chain events, aiming to reduce reliance on external oracles ^{[2] [3] [4]}.

Traders can now use Hyperliquid infrastructure to forecast US inflation on‑chain via fully collateralized CPI event contracts governed under HIP‑4, marking a direct challenge to existing prediction markets ^{[2] [1] [4]}.
