U.S. Spot Bitcoin and Ethereum ETFs Pull $1.2 B in Week Ending Sept 4

U.S. spot Bitcoin and Ethereum exchange‑traded funds (ETFs) recorded a combined net inflow of $1.20 billion for the five‑day period ending September 4. Bitcoin‑focused products drove the bulk of the activity, contributing over 80% of the total.

Bitcoin ETF inflows near $1 billion

Spot Bitcoin ETFs saw $986.7 million in net inflows, up 6.7% from the prior week’s $924.5 million. The largest single‑day intake occurred on September 3, accounting for roughly 74% of the weekly total. BlackRock’s Bitcoin offerings led the week with $691.5 million, followed by ARK Invest/21Shares’ ARKB with $137.7 million and Fidelity’s FBTC with $94.8 million. Cumulative net inflows across U.S. spot Bitcoin ETFs now stand at about $55.69 billion.

Ethereum ETF demand eases

Spot Ethereum ETFs added $215.3 million, a 73.6% decline from the previous week’s $815.7 million. BlackRock’s ETHA and ETHB together attracted $218.2 million, slightly exceeding the category’s net inflow after accounting for withdrawals. Fidelity’s FETH posted a modest $4.7 million net gain, while Grayscale’s higher‑fee ETHE recorded $37 million in outflows. Cumulative net inflows into U.S. spot Ethereum ETFs have reached approximately $13.19 billion.

Contrast with broader U.S. fund flows

During the same period, conventional U.S. equity funds saw $11.12 billion of withdrawals, driven by higher bond yields, oil prices, and geopolitical tensions. Money‑market funds attracted $48.76 billion in inflows. The crypto ETF inflows peaked on September 3, coinciding with a brief rally in Bitcoin (above $81,000) and Ethereum (around $2,500) after comments from a Federal Reserve governor.

Outlook

Upcoming U.S. economic data, including the September 11 consumer price index and the Federal Reserve’s September 16 policy meeting, could influence future ETF demand. Persistent inflation may pressure crypto prices, while softer readings could support continued inflows.
