Bitcoin crossed $125,000 for the first time ever last Saturday. The historic price level came as institutional investors poured money into spot Bitcoin exchange-traded funds.
U.S. spot Bitcoin ETFs recorded $3.24 billion in net inflows during the trading week. This ranks as the second-best performance since these investment products launched in January 2024.
The only stronger week occurred in late November 2024, when ETFs captured $3.38 billion. Last week’s numbers represent a dramatic $4.14 billion reversal from the previous week’s outflows.
BlackRock Dominates Bitcoin ETF Market
BlackRock’s IBIT fund led the market with $1.8 billion in weekly inflows. The fund now manages $96.2 billion in assets, making it the clear industry leader.
Fidelity’s FBTC came in second place with $692 million in new investments. This amount equals roughly 38% of what BlackRock’s fund attracted.
Trading volume data shows IBIT processed several billion dollars in daily transactions. Fidelity’s fund peaked at $715 million in daily volume during the same period.
Vincent Liu from Kronos Research credits ETF inflows for Bitcoin’s price surge. He also pointed to limited exchange supply, dollar weakness, and economic uncertainty as supporting factors.
Institutional Demand Exceeds Mining Output
Bitcoin miners produce approximately 900 new coins each day. Institutional buyers are acquiring Bitcoin much faster than this supply rate.
Research from River shows businesses bought an average of 1,755 Bitcoin daily in 2025. ETFs purchased roughly 1,430 Bitcoin per day during the same timeframe.
Corporate treasuries added 6,702 Bitcoin last week worth $1.2 billion. Japanese firm Metaplanet made the largest single purchase, acquiring 5,258 coins on Wednesday.
Crypto analyst Will Clemente emphasized the importance of ETF-driven buying. He noted this rally differs from previous moves driven by corporate treasuries or leveraged trading.
ETF Holdings Reach Historic Levels
Bitcoin ETFs currently hold over 1.5 million BTC valued at $188 billion. This represents 7.2% of Bitcoin’s total circulating supply.
Corporate Bitcoin treasuries contain more than 1.4 million coins. These holdings equal 6.6% of total supply and are worth over $166 billion.
Matt Poblocki from Binance Australia said the new all-time high demonstrates Bitcoin’s growing maturity. He highlighted regulatory progress and institutional adoption through U.S. spot ETFs.
Ethereum ETFs also posted strong numbers with $1.3 billion in weekly inflows. This came after the funds recorded their worst week ever in the prior period.
BlackRock’s ETHA fund collected $691.7 million in new investments. The fund handled about two-thirds of total Ethereum ETF trading volume last week.
Friday’s trading alone saw $12.22 billion in Ethereum ETF shares change hands. This single day accounted for approximately 62% of the entire previous week’s volume.
Bitcoin exchange balances have dropped to six-year lows, creating additional supply pressure. Analysts expect continued ETF inflows to drive further price increases through year-end.
