What happened?
US spot Bitcoin ETFs pulled in $3.24 billion last week, the second-largest weekly inflow since their January 2024 launch, reversing the prior week’s $902 million outflow. BlackRock’s IBIT dominated with $1.8 billion of the inflows while Fidelity’s FBTC took in $692 million. Bitcoin rallied past $125,000 as trading volumes surged and four-week inflows approached $4 billion.
Who does this affect?
Institutional investors and large asset managers are driving these flows and leaning toward big funds like IBIT, which now manages roughly $96.2 billion. Retail investors feel the price momentum and may follow ETF-driven moves, while ETF issuers compete for market share. Exchanges and miners are also affected because on-exchange Bitcoin balances have dropped to a six-year low, tightening available supply.
Why does this matter?
Big ETF inflows are adding upward pressure on Bitcoin prices by funneling fresh capital into the market and reducing supply on exchanges, which can amplify rallies. That concentration of flows into a few large funds like IBIT increases institutional influence on liquidity and short-term volatility. If momentum continues, analysts see room to test higher targets (the article notes upside toward ~$140,000) while key support sits near ~$117,300, so the ETFs are reshaping market dynamics and expectations.
