Bitcoin ETFs Attract Strong Inflows, Surpass $6.4 Billion YTD – Coincu

Bitcoin ETFs are experiencing significant inflows, driven by increasing institutional interest. As of May 2025, BlackRock’s iShares Bitcoin Trust ETF (IBIT) stands out by surpassing $6.4 billion in inflows, ranking it as the 8th largest ETF globally.

Market analysts, including Eric Balchunas, Senior ETF Analyst at Bloomberg, highlight the persistent upward trend in fund flows for IBIT. Despite brief fluctuations, it remains a key player in the ETF sector. Such institutional engagement could amplify Bitcoin’s influence in the market, setting a precedent for wider crypto asset recognition.

Bitcoin Inflow Surpasses $6.4 Billion Amid Institutional Surge

Eric Balchunas, Senior ETF Analyst at Bloomberg, shared insights on May 5th, noting a consistent upward trend in fund flows for IBIT, which ranks 8th in year-to-date inflows. BlackRock’s IBIT, alongside Vanguard’s VOO, remains a predominant force within the ETF sector. With over $6.4 billion in inflows, IBIT is bolstered by robust institutional engagement, potentially increasing Bitcoin’s market influence in a substantial manner. As Balchunas pointed out, for IBIT to overtake VOO, it would need to consistently draw in $1 billion to $4 billion daily. Balchunas cites persistence from investors, with between 97% to 98% maintaining their stakes despite fluctuations in the market.

Strong institutional interest in Bitcoin ETFs highlights growing market confidence, offering significant financial implications as demand for Bitcoin continues to elevate.

“The familiar pattern in weekly fund flows persists, with VOO and IBIT still holding the top two spots, just like last year when ‘Bitcoin-beta’ was a major theme. IBIT currently ranks 8th in year-to-date fund inflows (having briefly dropped out of the top 50), with cumulative inflows exceeding $6.4 billion. Since decoupling, it has been buying Bitcoin like crazy.” – Eric Balchunas, Senior ETF Analyst, Bloomberg
