Spot Bitcoin ETFs Record Over $3B Weekly Inflows, Second-Largest Since Launch

Bitcoin-linked exchange-traded funds (ETFs) in the United States experienced a sharp turnaround last week after several quiet sessions in September. Total inflows reached $3.24 billion, marking their second-strongest weekly performance since the products debuted in early 2024.

The surge signaled a swift shift in market sentiment, as the previous record of $3.38 billion was set in November 2024. The renewed inflows came as BTC revisited and slightly surpassed its all-time high.

IBIT Dominates ETF Inflows

According to SoSoValue, BlackRock’s iShares Bitcoin Trust (IBIT) drew the largest share of capital, collecting about $1.8 billion. With roughly $96.2 billion in total assets, the fund remains the largest among all spot Bitcoin ETFs.

Fidelity’s Wise Origin Bitcoin Fund (FBTC) followed with $692 million, representing a little over one-third of IBIT’s haul. On-chain data shows IBIT also handled the most trading activity, moving several billion dollars’ worth of shares daily. FBTC’s busiest day, meanwhile, reached around $715 million.

The return of strong inflows coincided with bitcoin’s climb above $125,000 on Sunday after retesting the August peak near $124,000. Analysts suggest that both seasonal optimism and safe-haven demand may be driving the move.

However, crypto analytics firm QCP noted that bitcoin’s latest breakout occurred largely without significant institutional or ETF-driven momentum. The firm attributed the price surge instead to active retail participation and increased hedging demand amid the partial U.S. government shutdown.

QCP added that while the market shows early signs of overheating, continued upside could persist if institutional inflows return and leveraged exposure remains contained. Sustaining the new highs, it said, will depend on whether funds maintain their current pace of participation.

Ethereum ETFs Rebound

Ethereum-based ETFs also recovered strongly after their biggest weekly outflows since launch. They attracted $1.3 billion last week, reversing a previous decline of about $2.1 billion.

Trading volumes mirrored the rebound, with $12.22 billion worth of shares exchanged on Friday alone. BlackRock’s ETHA ETF accounted for most of the activity, adding $691.7 million in inflows during the week.

Ether’s price hovered around $4,571 at press time, still below its record above $4,900. CoinGecko data shows the asset has climbed nearly 90% over the past year. Meanwhile, the renewed ETF activity points to improving sentiment toward the second-largest cryptocurrency.
