Hyperliquid Activates Validator-Settled HIP-4 Prediction Markets; BHYP Spot ETF Records $19M Single-Day Inflow on May 27

According to CoinDesk, Hyperliquid activated HIP-4 validator-governed outcome markets on 26 May 2026, a settlement model that bypasses external oracles like Polymarket's UMA protocol. HIP-4 allows traders to buy binary "Yes" or "No" positions on real-world events—CPI prints, FOMC decisions and corporate earnings—which settle at 1 USDC or 0 USDC, with validators ingesting news and voting directly on resolution.

The launch coincided with Bitwise's Hyperliquid spot ETF (BHYP) recording a $19 million single-session inflow on 27 May, the largest daily figure since its 15 May NYSE debut. BHYP has accumulated $55 million in cumulative inflows across 10 trading sessions and stands as the world's largest Hyperliquid ETF. Over the same window, the HYPE token reached an all-time high above $64.
