U.S. spot crypto exchange-traded funds extended their June drawdown, with Bitcoin and Ether products recording a combined $609.3 million in net outflows in the latest reported session. The data showed another broad withdrawal from regulated spot crypto funds as Bitcoin fell toward the mid-$60,000 range and Ether dropped below $1,900.
Spot Bitcoin ETFs accounted for most of the pressure, posting $519.1 million in net outflows. BlackRock’s iShares Bitcoin Trust led the redemptions with $388.6 million in withdrawals, followed by Grayscale’s GBTC at $83.5 million, Fidelity’s FBTC at $45.1 million and Ark Invest and 21Shares’ ARKB at $16.7 million. Morgan Stanley’s MSBT was the only tracked Bitcoin ETF to report a positive flow, adding $14.8 million.
Other Bitcoin funds were flat for the session. Bitwise’s BITB, Invesco’s BTCO, Franklin Templeton’s EZBC, Valkyrie’s BRRR, VanEck’s HODL, WisdomTree’s BTCW and Grayscale’s BTC recorded no net flow. The concentration of outflows in IBIT was particularly notable because BlackRock’s fund has been the dominant institutional accumulation vehicle since U.S. spot Bitcoin ETFs launched in January 2024.
Bitcoin ETFs drive the redemption cycle
The latest flow data shows that Bitcoin ETFs remain the main channel for institutional crypto de-risking. IBIT’s $388.6 million outflow represented nearly 75% of total spot Bitcoin ETF redemptions for the session, marking a sharp reversal for a product that has repeatedly absorbed large inflows during stronger market phases.
The withdrawal followed another negative session on June 1, when spot Bitcoin ETFs lost $483.8 million. Across the first two reported trading sessions of June, Bitcoin ETFs recorded more than $1 billion in net outflows, showing that selling pressure was not limited to a single fund or one-day rebalance. IBIT and Fidelity’s FBTC both posted consecutive withdrawals, while GBTC returned to meaningful outflows after a flat June 1 session.
The market backdrop was weak. Bitcoin traded near $66,884, down about 4.1% on the day, after moving between an intraday high of $70,131 and a low of $65,517. Ether traded near $1,868.80, down about 5.3%, with an intraday range between $1,819.40 and $1,985.76. The price action reinforced the link between ETF flows and broader risk appetite, with investors using regulated products to reduce exposure during declining spot-market conditions.
Why the flow reversal matters
ETF flows matter because they provide one of the clearest measures of regulated institutional demand for spot crypto exposure. During strong markets, consistent inflows can absorb available supply and support price momentum. During drawdowns, redemptions can reinforce downside pressure as investors use ETFs to cut exposure quickly through familiar brokerage and asset-management channels.
Spot Ether ETFs also weakened, recording $90.2 million in total net outflows. BlackRock’s ETHA lost $44.3 million, Grayscale’s ETH product saw $25.4 million in withdrawals, Fidelity’s FETH lost $15.6 million, Grayscale’s ETHE lost $3.9 million and BlackRock’s ETHB recorded a smaller $1 million outflow. Other Ether funds, including ETHW, TETH, ETHV, QETH and EZET, showed no net flow.
Ether ETF outflows were smaller than Bitcoin’s in absolute terms, but they were meaningful for a market with lower ETF liquidity and less institutional depth. The concentration of redemptions in BlackRock, Fidelity and Grayscale products suggests that larger allocators were actively reducing exposure rather than flows being driven only by smaller retail accounts.
For market participants, the immediate question is whether the first week of June becomes a short-term washout or develops into a sustained redemption cycle. Two consecutive heavy outflow sessions from Bitcoin ETFs, combined with accelerating Ether redemptions, point to weaker institutional risk appetite at a time when crypto prices are already under pressure.
The broader implication is that spot crypto ETFs are now functioning as high-liquidity risk instruments within traditional portfolios. That has improved access for institutions, but it also means capital can leave the asset class quickly when price momentum, macro conditions or volatility deteriorate.
