The iShares Bitcoin Trust (IBIT), the spot Bitcoin ETF of BlackRock, one of the world’s largest asset managers, has achieved a success that will mark the year 2025. On May 9, the fund recorded a net inflow of exactly $356.2 million, ending the trading week on a strong note. With this inflow, IBIT reached a series of uninterrupted capital inflows lasting 19 consecutive days, making it the longest inflow period so far this year.
19-Day Inflow Series
This uninterrupted inflow series that started on April 14 reveals that investors’ interest in the fund has not diminished despite the volatile Bitcoin market. During this period, where inflows continued, Bitcoin exhibited a fluctuating chart between $83,000 and $103,000. In particular, the fact that the BTC price exceeded $100,000 on May 8 and tested this level for the first time since the beginning of February created a positive atmosphere in the markets.
According to financial data provider Farside, IBIT recorded net inflows of $1.03 billion in the last trading week alone. This shows that institutional investors’ interest in Bitcoin continues steadily, not just on exceptional days. The fact that spot Bitcoin ETFs have become more attractive to long-term investors plays an important role in the increase in money flowing into such funds.

Previous Longest Inflow Streak in 2025
IBIT’s 19-day streak also surpasses the previous longest inflow streak in 2025. The previous record was a nine-day period between January 15 and January 28 — during Donald Trump’s inauguration.
IBIT’s longest inflow streak in history began in January 2024, when the ETF launched, and spanned a 104-day period of steady inflows that lasted until April 23, 2024. That period included March 2024, when Bitcoin reached its peak of $73,679, and ended with a correction that followed.
BlackRock ETF Wins Industry Award: “Best New ETF”
BlackRock’s IBIT ETF is being rewarded not only with investor interest but also industry recognition. On April 23, it won the “Best New ETF” award at the etf.com Annual ETF Awards, one of the most prestigious awards in the ETF industry. Bloomberg ETF analyst Eric Balchunas also praised this achievement.
According to the statements of André Dragosch, Head of European Research at Bitwise, increasing institutional inflows through Bitcoin ETFs provide the structural capital flow needed for Bitcoin to catch up with the market value of gold. Dragosch stated that their in-house models predict that Bitcoin’s price could exceed $1 million by 2029, he told Cointelegraph.
All this data indicates not only the immediate market excitement, but also that institutional adoption points to a structural transformation. The proliferation of Bitcoin ETFs plays an important role in the integration of crypto assets into the traditional financial system. The steady inflow trend shown by large funds such as IBIT strengthens Bitcoin’s position in the financial world day by day.
