Investors pulled roughly $2.5 billion from US-traded spot Bitcoin and Ethereum ETFs through June 18, while Hyperliquid (HYPE) and XRP products attracted a combined $74 million, according to data from Farside Investors and SoSoValue. The disparity suggests a de-risking move rather than a rotation, as Bitcoin ETF outflows outpaced HYPE inflows by about 46-to-1.
Bitcoin and Ethereum lead outflows
Spot Bitcoin ETFs shed nearly $2.3 billion in the period, with Ethereum ETFs losing about $200 million. Bitcoin ETFs recorded negative flows on 11 of 14 trading sessions in June; on June 18 alone, Bitcoin ETFs saw $90.7 million in outflows while Ethereum ETFs lost $12.8 million. Citi has estimated that spot Bitcoin ETF flows account for roughly 45% of weekly BTC price moves, a figure that aligns with the persistent negative sessions and Bitcoin's price performance.
The Federal Reserve held its target range at 3.50% to 3.75% on June 17 and described inflation as still elevated, keeping short-term dollar yields meaningful and raising the opportunity cost of volatile crypto exposure. This macro backdrop likely contributed to the broad ETF outflows.
Hyperliquid's HYPE draws institutional interest
Bitwise launched its spot Hyperliquid ETF (BHYP) on May 14, one of the first US spot Hyperliquid products and the first to incorporate in-house staking. Farside Investors also lists 21Shares' THYP and Grayscale's HYPG, showing cumulative HYPE ETF inflows of about $189 million through June 18. The $50 million June inflow comes from a category that launched mid-May and has logged fewer than 25 trading sessions, making consistency the more meaningful signal.
The demand pattern reads as a concentrated institutional bet on an on-chain derivatives venue. The bull case holds that persistence through a broadly negative ETF environment shows Hyperliquid has a distinct buyer base, such as allocators expressing a thesis on on-chain perpetuals infrastructure. The bear case is that the category is six weeks old, assets under management are thin, and a single week of institutional redemptions could reverse the cumulative inflow figure.
XRP shows recurring demand
SoSoValue-aggregated data showed XRP spot ETFs added $10.6 million during the June 14-18 trading week, with cumulative inflows reaching about $1.5 billion and total net assets at roughly $995 million. XRP ETFs logged only two negative weeks since mid-March, a stretch that included several sessions when Bitcoin and Ethereum products saw outflows, pointing to recurring appetite for regulated access to an asset whose retail and institutional base predates ETF wrappers.
The bull case is that two negative weeks in over three months, amid a difficult broader environment, show a durable buyer base. The bear case is that $1.5 billion in cumulative inflows across several months, with weekly additions of $10 million to $25 million, falls far short of the scale seen in Bitcoin ETF sessions like June 18's $90 million outflow.
What the altcoin inflows signal
Altcoin inflows totaled about $74 million, less than 3% of the $2.5 billion that left Bitcoin and Ethereum ETFs. The two altcoin categories with net inflows carried specific narratives: Hyperliquid as an on-chain derivatives venue, XRP as a regulated-access product with a pre-existing holder base. Whether HYPE and XRP inflows hold in July depends on whether Bitcoin and Ethereum ETFs return to positive weekly flows. If they do, the altcoin bid looks like early positioning. If BTC and ETH keep shedding assets, the residual inflows into smaller products describe the floor of crypto ETF demand, with HYPE and XRP as the last positions allocators held on to.
