U.S. Spot Bitcoin ETF Sees Net Inflow of Nearly $1.7 Billion in Five Days

According to SoSoValue data, the U.S. spot Bitcoin ETF recorded net inflows for the fifth consecutive trading day this Wednesday, with net inflows of $46.3 million on that day, attracting a total of $1.69 billion over five days. BlackRock's IBIT saw a single-day inflow of $134.6 million, offsetting the net outflows from Fidelity's FBTC and three other funds.

For Bitcoin, ETF funds are one of the most direct windows to observe institutional demand. The U.S. spot Bitcoin ETF is approaching its sixth consecutive week of inflows, which, if achieved, would be the longest weekly inflow period since July 2025.

This round of capital inflow has occurred during the rebound phase of Bitcoin. After falling to around $62,000 in February, Bitcoin has recently rebounded to the $81,000 to $82,000 range, gaining 26% over the past three months, with the price recovery echoing the ETF fund inflows in terms of timing.

Nick Ruck, Director at LVRG Research, stated that recent ETF inflows indicate that institutional investors are viewing Bitcoin as a long-term strategic allocation rather than a short-term speculative trade. He believes that this provides hope for a new bull market cycle.

Ethereum spot ETFs also saw an improvement in funding, with inflows of $11.6 million on Wednesday, marking the fourth consecutive day of inflows, with a total inflow of $271.6 million over four days.

The divergence lies in whether this rebound is driven by long-term configuration funds or just a phase of buying after price increases. If ETFs continue to maintain weekly inflows, the narrative of institutional allocation will be easier to sustain; if funds weaken, the market will reassess the support for the rebound.
