U.S. spot Bitcoin ETFs extended their momentum on May 12, pulling in more than $220 million in fresh allocations as institutional demand held firm through a volatile macro backdrop. The steady appetite for regulated Bitcoin exposure helped lift monthly inflows toward the $1 billion mark, reinforcing the growing role of Bitcoin ETFs in shaping market sentiment and liquidity.

Institutional Demand Lifts Bitcoin ETF Flows Through Volatile Trading

The latest session added another strong day to a broader rebound that has defined the first half of May. Farside data reported that Bitcoin ETFs have now accumulated more than $2.4 billion this month, with BlackRock’s IBIT continuing to lead the field in asset growth. Analysts noted that Bitcoin ETFs have become a central gauge of institutional conviction, especially as hotter U.S. inflation data pushed investors into a more cautious stance across equities and crypto‑linked stocks.

Bitcoin traded near the $80,000 to $81,000 range during the session. Despite the choppy backdrop, long‑term allocators continued to add exposure through Bitcoin ETFs, which remain the preferred vehicle for regulated access to the asset. IBIT alone brought in more than $720 million during the first week of May, far outpacing other crypto investment products. Ethereum‑linked funds, by contrast, saw mixed flows even after the network’s recent Pectra upgrade, highlighting Bitcoin’s stronger positioning as a macro asset.

Hyperliquid ETF Sees Solid First Day With $1.2M in Inflows

Alongside the strong session for Bitcoin ETFs, 21Shares’ Hyperliquid ETF (THYP) made its Nasdaq debut with $1.2 million in net inflows and $1.8 million in trading volume. Bloomberg analyst James Seyffart described the launch as solid and above average, though far smaller than earlier high‑profile crypto ETF debuts such as BSOL and XRPC. THYP tracks the spot price of the HYPE token, which is tied to the Hyperliquid perpetual futures platform.

This platform has processed more than $8.4 trillion in volume since 2023. The fund enters a growing field of altcoin‑focused ETFs following the SEC’s shift toward generic listing standards. Additional Hyperliquid-linked products from Bitwise and Grayscale are pending approval, with fee structures remaining a key point of differentiation.
