U.S.-traded spot Bitcoin ETFs lost nearly $2.3 billion through June 18, extending a brutal June for the category. Ethereum ETFs weren't far behind, shedding around $200 million over the same period. Meanwhile, a handful of newer altcoin-based products — Hyperliquid and XRP ETFs — posted modest net inflows, but their totals remain a rounding error compared with the giants.
Bitcoin and Ethereum: 11 bad days out of 14
Bitcoin ETFs recorded negative flows on 11 of the first 14 trading sessions in June. On June 18 alone, they bled $90.7 million, while Ethereum ETFs lost another $12.8 million. The persistent selling comes even as the Federal Reserve held its target range at 3.50% to 3.75% on June 17 and described inflation as still elevated. Citi has estimated that spot Bitcoin ETF flows account for roughly 45% of weekly BTC price moves, though that figure isn't independently verified.
Hyperliquid and XRP: small but steady
Bitwise launched its spot Hyperliquid ETF (ticker: BHYP) on May 14. Through June 18, cumulative HYPE ETF inflows reached about $189 million, according to Farside Investors. The $50 million that flowed into Hyperliquid products during June came from a category that has existed for fewer than 25 trading sessions. XRP spot ETFs added $10.6 million during the week of June 14-18, bringing cumulative inflows to roughly $1.5 billion. Total net assets across the XRP ETF category now sit at about $995 million. XRP ETFs have logged only two negative weeks since mid-March.
Altcoins still a footnote
Combined altcoin inflows — covering Hyperliquid, XRP, Solana, and a few others — totaled about $74 million through June 18. That's less than 3% of the $2.5 billion that left Bitcoin and Ethereum ETFs over the same stretch. Solana ETFs had $3.4 million in outflows. To put the scale in perspective: Bitcoin ETF outflows outpaced HYPE inflows by roughly 46-to-1 and XRP inflows by about 96-to-1.
The numbers highlight a market that's still overwhelmingly tied to Bitcoin and Ethereum, even as a handful of altcoin products find buyers. Whether those niche inflows can accelerate — or whether the broader ETF selloff deepens — will depend partly on what the Fed does next. The next rate decision is scheduled for late July.
