BTC surged past the $125,000 mark amid a Bitcoin ETFs rebound, as Bitcoin Treasury companies purchased an additional $1.2 billion worth of the flagship cryptocurrency to their reserves last week.
According to data from Coinglass, while Bitcoin Treasury companies may have contributed to the rally that pushed Bitcoin to a new all-time high, the Bitcoin ETFs rebound, which saw a net inflow of $3.24 billion last week, was the main driver of the emerging Bitcoin price rally.

Experts Divided in Opinion
Crypto analysts now predict that altcoins that are linked to Bitcoin’s success such as Bitcoin Hyper ($HYPER) could instigate a rally that could lead to a new BTC all-time-high. Nonetheless, experts are divided in their opinion on whether the increasing corporate buying of crypto was a sign of growing distrust in the USD or it’s a rising demand for Bitcoin.

The US Dollar, also known as the greenback, has experienced its worst first half of the year yet since 1973. This has prompted traders to look for alternative assets that are not tied to the dollar. As a result, the demand for Bitcoin has nearly doubled over the past year, as evidenced by last week’s Bitcoin ETFs rebound.

Demand for BTC Surpassed Supply
The Bitcoin ETFs rebound is believed to be responsible for much of the increased activity, leading to a shrinking Bitcoin supply. Data show that by August 11, 2025, crypto-based ETFs had accumulated over $29.4 billion in inflows.

However, last week’s Bitcoin ETFs rebound has gone down in the record books as its second-best week ever, after the November 2024 record-breaking $6.2B in $BTC inflows. Data from the financial research company River shows that demand has surpassed supply, leading to a new all-time high for BTC, surpassing the $125K mark.
Large ETF inflow is a Sign of a Weakening Dollar
On average, ETFs were buying at least 1,430 $BTC each day. On-chain data shows that ETFs now hold over 1.5 million Bitcoin, with Michael Saylor’s strategy owning 3% of the total possible global supply of $BTC. The ongoing Bitcoin ETFs rebound is the clearest sign yet of growing institutional interest in Bitcoin, making it one of the best investments in the cryptocurrency market currently. Vincent Liu, CIO at Kronos Research, in a recent note:
“ETF inflows were the real spark […] tight exchange supply, a weaker dollar, and macro uncertainties are reinforcing bullish momentum.”
According to data from Bitcoin Treasuries, companies added 6,702 BTC last week — worth approximately $1.2 billion. The largest corporate buyer was Metaplanet, a Tokyo-based investment firm often dubbed “Japan’s MicroStrategy,” which acquired 5,258 BTC last Wednesday alone.
Conclusion
The current Bitcoin ETFs rebound aligns with a prediction by Michael Saylor, Executive Chairman of MicroStrategy, who predicted in September that corporate and institutional demand would accelerate into year-end. As the forecast unfolds, analysts believe that Bitcoin’s Q4 outlook is bullish, with an imminent new all-time high for BTC expected.
