前天还在说两天抽走约7.5亿，昨天机构通道就掉头了。
Farside口径：美国比特币现货ETF，9月15日净流出约4.504亿，16日再流出约2.959亿；17日合计净流入约1.595亿美元。主力是贝莱德IBIT，单日净流入约1.837亿。Fidelity FBTC仍流出约1660万，HODL流出约760万。律动快讯同一组数。以太坊没跟上：同日ETH现货ETF净流出约3930万，ETHA单独流出约4290万。
价格也回来了。律动引HTX：9月18日比特币突破7.8万美元，24小时涨约2.01%；以太坊突破2500美元，涨约1.22%。CoinDesk写到，现价大致回到周三美联储加息前水平。背景还是那两记闷棍：参议院CLARITY卡在约49票，加息25个基点到3.75%–4.00%。周二盘中低点约74887美元，很快稳住。九月迄今约跌1.5%，比往年九月均值弱得少。
判断就一句：这是止出血加空头回补的反弹，不是机构全面回补。BTC通道转正才一天，ETH还在撤。短线更该盯IBIT能不能连着进，以及7.8万上方能不能收稳。别把一天流入当成趋势重启。

U.S. spot Bitcoin ETFs recorded a combined net inflow of $731 million on September 3, marking a sharp return of institutional demand after a difficult start to the month. The figures, based on SoSoValue data, show that investors moved aggressively back into Bitcoin-linked investment products as BTC reclaimed the $80,000 level.
BlackRock dominates the flow
BlackRock’s iShares Bitcoin Trust (IBIT) was the clear leader, attracting $454 million in a single session. That pushed IBIT’s cumulative historical net inflows to approximately $63.939 billion, reinforcing its position as the dominant U.S. spot Bitcoin ETF.
BlackRock’s own data shows IBIT had about $63.44 billion in net assets as of September 3, while its benchmark Bitcoin price was around $81,482.
ARKB follows with $138M
Ark Invest and 21Shares’ ARKB ranked second, recording approximately $138 million in net inflows. Its cumulative historical net inflow subsequently reached about $1.457 billion.
The concentration of flows in IBIT and ARKB is notable because it suggests that the latest demand was not simply scattered across smaller ETF products; investors were directing substantial capital toward some of the largest and most established Bitcoin funds.
A dramatic reversal from September 1
The $731 million inflow becomes even more significant when placed against the beginning of September. U.S. spot Bitcoin ETFs recorded roughly $236.5 million in net outflows on September 1, with IBIT itself accounting for about $201.2 million of withdrawals that day.
That means IBIT went from being the largest source of ETF outflows at the beginning of the month to the largest source of inflows just two trading sessions later—a notable reversal in institutional positioning.
Bitcoin’s move above $80,000 adds context
The ETF inflows arrived alongside a powerful Bitcoin recovery. BTC climbed above $80,000 on September 3, reaching roughly $81,800 during the session.
Macro conditions also became more supportive. Federal Reserve Governor Christopher Waller indicated that he could support keeping interest rates unchanged if incoming inflation data continues to show improvement. His comments helped reduce expectations of another September rate hike, while U.S. Treasury yields declined.
This combination—strong ETF demand, a rebound in Bitcoin above $80,000 and softer rate-hike expectations—created a favorable backdrop for the cryptocurrency market.
The bigger picture
According to Binance’s report citing SoSoValue, U.S. spot Bitcoin ETFs collectively held approximately $103.34 billion in net assets, representing about 6.32% of Bitcoin’s market capitalization, while cumulative net inflows stood at roughly $55.44 billion.
The September 3 inflow therefore represents more than just a strong trading day. It demonstrates that large-scale institutional demand remains capable of returning rapidly after periods of selling pressure.
However, one strong session should not be interpreted as confirmation of a sustained bull market. Bitcoin still faces macroeconomic uncertainty, upcoming U.S. inflation and employment data, and the Federal Reserve’s September policy decision. The ability of ETF inflows to remain consistently positive will be more important than a single $731 million print.
Bottom line: The latest ETF data provides a strong bullish signal for Bitcoin. $731 million of net inflows, led by $454 million into BlackRock’s IBIT, shows that institutional buyers stepped back into the market aggressively as BTC reclaimed $80,000. The key question now is whether this renewed demand can persist.
