BlackRock’s Ishares Bitcoin Trust (IBIT) has risen to the edge of a major milestone, with approximately $98 billion to $100 billion in assets under management, according to market reports.
In just one year since its launch, the fund has generated approximately $204.44 million to $245 million in annual revenue, driven by steady inflows and a 0.25% management fee. This rapid rise has made IBIT one of the most profitable products in BlackRock’s lineup.
Rapid growth and profits
ibit reached its current size in about 435 days. Based on reports, this is much faster than many legacy funds needed to build similar scale. Vanguard’s S&P 500 ETF (VOO) took about 2,011 days to reach $100 billion.
Market watchers say IBIT could become the fastest ETF in history to reach $100 billion. Bloomberg analyst Eric Balkunas describes the rise as “absurd.”
Mathematics is easy. If the price of Bitcoin increases in addition to large flows, AUM will be higher and fee income will increase. That loop was strong this year.

Flow numbers and market movements
In a recent trading day, the US Spot Bitcoin ETF saw net inflows of nearly $1.2 billion. IBIT reportedly earned about $970 million of that total.
Based on market coverage, more than half of ETF inflows into the US market went into IBIT, highlighting its lure for many investors. When money is poured in on this scale, demand for the underlying Bitcoin is high, amplifying price movements.
Some traders are watching these inflow days closely as similar spikes have approached local price tops in the past.
Market impacts and risks
The report revealed some clear risks to investors and the broader market. One is the premium or discount that can form between an ETF’s market price and its net asset value. That gap can widen in moments of stress.
The other thing is regulation. Regulations in the US or abroad may change, which may affect flows. Competition is also a factor. Pricing pressure from rival publishers could change revenue forecasts.
Finally, it facilitates rapid growth in the beginning. Maintaining this pace becomes more difficult as the base grows.
Mechanics and strategic moves
IBIT’s structure relies on daily creation and redemption by authorized participants and uses a Bitcoin Holdings primary custody setup.
According to filings and industry reports, BlackRock is exploring product enhancements such as a Bitcoin “premium income” ETF aimed at generating yield through options strategies, and is taking steps such as filing to create a supporting trust entity. These moves suggest that the company is planning multiple ways to meet demand.
