According to Lookonchain, on June 16, Bitcoin ETFs recorded a significant net inflow of 2,864 BTC worth $305.87 million, driven mainly by iShares (Blackrock) which added 2,272 BTC ($242.6 million) to its holdings, now totaling 671,795 BTC ($71.74 billion). In contrast, Ethereum ETFs faced a net outflow of 3,748 ETH ($9.84 million), led by Fidelity's withdrawal of 3,496 ETH ($9.18 million), leaving the fund with 465,263 ETH. These contrasting ETF flows indicate strong institutional demand for BTC, suggesting upward price momentum and increased trading volumes, while ETH faces short-term pressure as outflows continue.

According to Matt Hougan, citing data from FarsideUK, US spot Bitcoin ETFs attracted $5.86 billion in inflows while Ethereum spot ETFs saw $564 million in May 2025. This significant surge in institutional investment signals strong bullish sentiment for both BTC and ETH, reinforcing their positions as leading crypto assets and potentially driving further price appreciation. Traders should note the ongoing momentum in ETF products as they remain major liquidity channels and market drivers. (Source: Matt Hougan on Twitter, June 2, 2025; FarsideUK)
