Key highlights:

  • Bitcoin ETFs took in $986.9 million in net inflows for the week ended September 4
  • BlackRock's IBIT led the capital influx, responsible for about 70% of the weekly total

Institutional demand for Bitcoin kept building last week as US spot funds brought in almost $1 billion. BTC ETFs recorded $986.9 million in net inflows for the week ended September 4, according to data from SoSoValue. This extended a positive streak to three consecutive weeks, building on the $924.5 million recorded the week before.

Bitcoin ETF sees third straight week of inflows

The institutional funds extended the positive momentum despite a brief pullback. BlackRock's IBIT fund attracted $691.5 million out of the total capital that came in. This comes even as the weekly volume on the funds slipped to around $14.6 billion from almost $19 billion the week before.

Ethereum ETFs also saw a similar performance. Its funds saw $218.4 million for their third straight week of inflows. Its trading volume also dropped to $4.1 billion from $6.3 billion.  In conjunction, the two ETFs recorded over $1.2 billion in the week.

The Bitcoin price has since slipped below $79,000, but is still maintaining most of its recent gains.

 

Last week's activity builds on a strong August. Bitcoin ETFs pulled in $3.52 billion for the month, their best monthly performance since September 2025. Ethereum ETFs, on the other hand, brought in $1.85 billion, their strongest month since August 2025.  All of this suggests institutional appetite for regulated crypto exposure has held up.

Dormant whales stir as bulls eye higher targets

In another development, a couple of dormant Bitcoin wallets have suddenly come back to life. On September 5, twelve addresses moved 600 BTC, worth around $48 million, after 16 years of inactivity. Lookonchain first flagged seven of those wallets moving 350 BTC, worth about $28 million. 

This activity came with bullish commentary from experts. Crypto Banter founder Ran Neuner said in an interview that Bitcoin's rebound could mark the start of a new bull cycle. 

"My thesis is that we're very, very much in a new bull market," he said. He highlighted the asset's bounce off its 200-week moving average and unusually low volatility to back his thesis.

Neuner said it could potentially reach $300,000 using the scale of the last market cycle. He estimated a sixfold to sevenfold gain from bottom to peak. Neuner also suggested any move to new highs could arrive faster than many expect. 

"I think we're going to be back at all-time highs much sooner than people expect," he said, adding that "when the Bitcoin moves actually start, they're quite violent."

Meanwhile, there are still experts who are on the cautious side. Fidelity said last week that the bear market may not be over even with the strong ETF inflows.
