Bitcoin ETFs Extend 4-Day Inflows with $553M amid Rally

U.S. spot Bitcoin ETFs recorded net inflows for a fourth consecutive day on Sept.12, adding $552.8 million and matching their joint-longest streak since mid-August. Over the four-day run, Bitcoin ETFs have attracted about $1.7 billion, with Wednesday’s $757.1 million flow the largest daily gain since July 16. BlackRock’s IBIT led at $366.2 million, followed by Fidelity’s FBTC and Bitwise’s BITB. Concurrently, spot Ether ETFs notched a three-day inflow streak, adding $113.1 million after six days of withdrawals. Renewed institutional demand drove Bitcoin above $115,000—up about 3.2% in three days—and Ether back to $4,500 with a 5% gain. The rally reflects growing expectations of a 25-basis-point Federal Reserve rate cut at the Sept.17 meeting.
Bullish
These sustained net inflows into spot Bitcoin ETFs indicate strong institutional demand, likely sustaining upward pressure on BTC prices in the near term. The four-day streak and record daily flows underscore investor confidence, potentially triggering further inflows and supporting a continued rally. In the long term, consistent ETF adoption may enhance market liquidity and reduce volatility as more institutional capital enters, underpinning a bull case for Bitcoin.
