Investors pulled $2.5B from Bitcoin and Ethereum ETFs, but Hyperliquid and XRP still found buyers

Through June 18, US-traded spot Bitcoin ETFs shed nearly $2.3 billion, and Ethereum ETFs lost around $200 million. Hyperliquid products attracted about $50 million in net inflows, XRP ETFs added roughly $24 million, and Solana finished with $3.4 million in outflows.

Altcoin inflows totaled about $74 million, less than 3% of the $2.5 billion that left Bitcoin and Ethereum ETFs over the same period.

Bitcoin ETFs outpaced HYPE inflows by roughly 46-to-1 and XRP inflows by roughly 96-to-1, shutting down the argument for a rotation.

Hyperliquid’s HYPE persistent bid

Bitwise launched its spot Hyperliquid ETF (BHYP) on May 14, describing it as one of the first US spot Hyperliquid products and the first to incorporate in-house staking.

Farside Investors’ flow tables also list 21Shares’ THYP and Grayscale’s HYPG, showing cumulative HYPE ETF inflows of about $189 million through June 18, even as Bitcoin and Ethereum products bled.

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, specific enough in its thesis to hold while broader crypto ETF appetite contracted.

The bull case holds that persistence through a broadly negative ETF environment shows that Hyperliquid has a distinct buyer base, such as allocators who express a thesis on on-chain perpetuals infrastructure and stay in the position as BTC and ETH products shed assets.

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 built across the product’s entire trading history.

XRP’s 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 across the category 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, with existing holders seeking a compliant format for exposure they already held.

The bull case is that two negative weeks in three-plus months, amid a difficult broader environment, show a durable buyer base with an appetite that persists through macro- and crypto-specific weakness.

The bear case is that $1.5 billion in cumulative inflows across several months, distributed across a category with net assets below $1 billion, describes measured demand with weekly additions of $10 million to $25 million landing far short of what would register against BTC ETF sessions like June 18’s $90 million outflow.

Category	June flow through June 18	Key signal	Bull case	Bear case
HYPE ETFs	+$50M	Persistent inflows despite broader ETF weakness	Distinct buyer base for on-chain derivatives infrastructure	Category is very young and thin; one redemption week could reverse the signal
XRP ETFs	+$24M	Recurring regulated-product demand	Existing holder base may support steady ETF inflows	Weekly additions remain too small to offset BTC/ETH redemptions
BTC + ETH ETFs	-$2.5B	Core crypto ETF demand is still contracting	Outflows could reverse if macro risk appetite improves	Persistent redemptions remain the dominant market signal

What the Bitcoin outflow data shows

Bitcoin ETFs recorded negative flows on 11 out of the 14 trading sessions in June. The June 18 outflow of $90.7 million occurred on the same day Ethereum ETFs also shed $12.8 million.

ETF flows carry macro weight because they represent brokerage-account demand, dollars moving through regulated wrappers with settlement and custody infrastructure, the kind of institutional flow that moves price over weekly timeframes.

Citi estimated that spot Bitcoin ETF flows account for roughly 45% of weekly BTC price moves, a figure from a bank research note that could not be independently verified in Citi’s primary materials, but whose directional claim tracks the persistent negativity of June sessions and BTC’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 relative to its 2% goal, keeping short-term dollar yields meaningful and the opportunity cost of volatile crypto exposure working against allocators who might otherwise add to ETF positions.

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.
