Bitcoin ETF Weekly Outflows Breach $1.257 Billion
US spot Bitcoin (BTC) exchange-traded funds posted $1.257 billion in net outflows for the week of May 18 through May 22, the largest weekly bleed since early April. Ethereum (ETH) spot ETFs shed assets in parallel. Meanwhile, funds tied to Solana (SOL), XRP (XRP), and Hyperliquid (HYPE) bucked the trend with positive net inflows.
The divergence points to a rotation out of the two largest cryptocurrency assets and into smaller-cap alternatives.
Bitcoin ETF Weekly Outflows Drive the Headline Number
The $1.257 billion weekly net outflow figure was reported on May 25, citing Wu Blockchain data. Bitcoin ETF flows had been broadly positive through much of Q1 2026, making last week’s figure a notable reversal.
No single fund’s daily breakdown was disclosed in the available data, but the aggregate reading clears the $500 million weekly threshold that Nonce treats as a significant institutional flow event.
Ethereum ETFs joined the selloff. The outflow quantum for ETH products was not broken out in available figures, but both major asset classes moved in the same direction across the five trading days.
The HYPE ETF product drew $72.38 million in inflows during the same period.
SOL and XRP ETF products also attracted positive flows, though specific weekly totals for those products were not available at publication time.

Background
Spot Bitcoin ETFs launched in the United States in January 2024 after the Securities and Exchange Commission approved products from asset managers including BlackRock and Fidelity. The products gave institutional and retail investors a regulated way to gain Bitcoin price exposure without holding the asset directly.
Weekly inflow and outflow data became a closely watched proxy for institutional sentiment toward Bitcoin after the products accumulated tens of billions of dollars in assets within their first year.
The week of May 18 through May 22 coincided with a period of broader macro caution. Bitcoin had pulled back from its May highs, and Google Trends data for the scan window showed rising searches for “bitcoin valore” and “cours bitcoin dollar,” suggesting European retail interest remained active even as institutional positioning turned defensive.

What the HYPE ETF Signal Suggests
The Hyperliquid ETF inflow of $72.38 million in a single week is notable for a product tied to an asset ranked 11th by market cap.
Hyperliquid is a layer-one blockchain built around a high-performance decentralized exchange for perpetual futures and spot trading. Perpetual futures are derivatives contracts with no expiration date, used to take leveraged positions on cryptocurrency prices.
The protocol’s native token, HYPE, trades at roughly $62.63 with a market cap near $14.9 billion as of this scan.
The inflow figure suggests some institutional capital is rotating from Bitcoin into higher-beta, narrative-driven assets rather than exiting cryptocurrency entirely.
Outlook
The $1.257 billion weekly outflow number will draw scrutiny if it extends into the week of May 25. A second consecutive week above $500 million in Bitcoin ETF net outflows would deepen concern about a sustained institutional retreat.
Conversely, a reversal in the first trading days of the new week could reframe last week’s figure as profit-taking rather than a trend change. The SOL, XRP, and HYPE inflow data will remain a secondary watch item as a gauge of where institutional appetite is actually landing.
