Bitcoin ETFs saw outflows during the session. The surge came as Bitcoin’s price jumped more than 7%. briefly trading in the $68K-$69K range after a volatile stretch. The sharp institutional buying quickly caught market attention. It revived bullish sentiment across crypto markets.

BlackRock Leads the Institutional Charge

BlackRock’s IBIT once again dominated the flows. The fund alone pulled in roughly $297.4 million on the day. It is equal to about 4,300 BTC worth of demand. This pushed IBIT’s cumulative historical inflows to more than $61 billion. That reinforcing its position as the clear market leader among spot Bitcoin ETFs.

However, the strength was broad based. Fidelity, Bitwise and ARK 21Shares also recorded positive inflows. Even Grayscale’s GBTC, which had seen persistent outflows earlier in the year. It added more than $100 million in net inflows. The coordinated buying across issuers signaled renewed institutional confidence after weeks of uneven flows.

Ethereum ETFs Join the Rally

The positive momentum was not limited to Bitcoin products. U.S. spot Ethereum ETFs also recorded solid demand. According to the same dataset, Ethereum funds saw about $157.2 million in net inflows during the session. This parallel move suggests investors are again increasing exposure to major crypto assets. Rather than rotating out of the sector. Still, Bitcoin products continue to dominate total flows and assets by a wide margin.

As of the latest update, total net assets across U.S. Bitcoin spot ETFs stood near $87-91 billion. It depends on intraday market moves. The products now represent roughly 6% of Bitcoin’s total market capitalization. It’s a notable milestone for institutional adoption.

Market Context and Sentiment Shift

The strong inflow day comes after a shaky period for crypto ETFs. In recent weeks, funds had experienced notable outflows as Bitcoin pulled back below $65K. The macro uncertainty weighed on risk assets. This latest surge therefore stands out as a clear sentiment shift.

Some market watchers described the move as a sign that large investors are buying the dip. Influencers on social media quickly labeled the flows bullish. It is pointing to the steady accumulation trend since the ETF launched in 2024. Cumulative net inflows across Bitcoin spot ETFs have now surpassed $54 billion. This underscores sustained long term demand despite short-term volatility.

What Comes Next

Whether the momentum continues will depend largely on Bitcoin price stability and broader macro conditions. Still, the latest data shows institutions remain active buyers during periods of weakness. If inflows stay strong in the coming sessions. ETFs could again become a major driver of Bitcoin’s next price move.
