Bitcoin ETFs Record Historic Back to Back Billion Dollar Inflows as BlackRock IBIT Reaches New Milestone
US spot Bitcoin ETFs recorded over $1 billion in daily inflows for two consecutive days this week. This represents the first time since their January 2024 launch that these investment products achieved back-to-back ten-digit inflows. According to Cointelegraph, Friday's trading session brought $1.03 billion in total inflows across all 11 Bitcoin ETF products. This followed Thursday's $1.17 billion inflow, which was the second-largest daily inflow since inception.
The week delivered $2.72 billion in total inflows across five trading days. NovaDius Wealth Management president Nate Geraci noted that only seven inflow days have exceeded $1 billion since launch. Two of these occurred in the past two days, with the previous occurrence dating back to January 17. The $1.17 billion Thursday inflow trailed only the record $1.37 billion recorded on November 7, 2024, when Donald Trump won the US presidential election.
Why This Matters for Bitcoin Markets
These record inflows demonstrate the massive institutional appetite driving Bitcoin's recent price surge to new highs. Bitcoin reached $112,000 on Wednesday and continued climbing to $118,780 by Friday, according to CoinMarketCap data. The demand far exceeded Bitcoin's natural supply, with ETFs purchasing approximately 10,000 Bitcoin on Thursday while the network produced only 450 coins.
BlackRock's Bitcoin ETF crossed $80 billion in assets under management during this period. Bloomberg analyst Eric Balchunas confirmed this made IBIT the fastest ETF to reach this milestone in just 374 days. The achievement came as Bitcoin's 90-day rolling volatility dropped to record lows, making the asset more attractive to risk-averse institutional investors.
Jan3 CEO Samson Mow warned that current demand levels are unsustainable at these price levels. Wednesday saw Bitcoin ETF demand reach 22 times greater than daily mined supply. This supply squeeze dynamic has created persistent buying pressure throughout 2025, as we reported that central banks are moving away from US Treasuries toward alternative assets like Bitcoin and gold amid growing geopolitical tensions.
Industry Implications for Cryptocurrency Adoption
The consecutive billion-dollar inflow days reshape Bitcoin's position in traditional finance. Total assets for all spot Bitcoin ETFs crossed $140 billion for the first time, according to ETF analyst Eric Balchunas. However, he noted that Bitcoin's price surge did most of the heavy lifting for this achievement. BlackRock now earns more revenue from its IBIT fund than its flagship S&P 500 fund on an annual basis.
This institutional momentum extends beyond individual ETFs. 99Bitcoins reports that BlackRock's shift reflects traditional finance embracing Bitcoin as more than just a speculative play. The world's largest asset manager now calls Bitcoin a strategic asset, citing its fixed supply and independence from central banks.
The development creates concentration risks within Bitcoin ownership structures. BlackRock's IBIT now holds over 55% of all US Bitcoin ETF assets, making it the dominant player in cryptocurrency investment products. CoinDesk notes that this concentration may influence competitor strategies as the SEC considers streamlined approval processes for future cryptocurrency ETFs.
