IBIT Breaks Records, Topping $80B AUM Amid $1 Billion Inflow Into Spot Bitcoin ETFs

Spot Bitcoin ETFs Draw Over $1B as IBIT Shatters Growth Records

Spot bitcoin ETFs pulled in more than $1 billion of inflows on Thursday, one of their biggest single-day hauls since these products hit the market. The surge arrived as bitcoin smashed through a fresh all-time high above $118,000.

BlackRock’s iShares Bitcoin Trust (IBIT) led the charge, surpassing $80 billion in assets under management (AUM). IBIT achieved this milestone in just 374 days, making it the fastest ETF on record to hit that mark. By comparison, the previous record-holder, Vanguard’s S&P 500 ETF (VOO), needed 1,814 days to reach the same size, according to Bloomberg Intelligence senior ETF analyst Eric Balchunas.

Thanks to its rapid growth, IBIT now ranks as the world’s 21st largest ETF—a remarkable feat for a fund launched only about a year ago following the U.S. green light for spot bitcoin ETFs.

Thursday’s billion-dollar influx marks only the fourth time spot bitcoin ETFs have seen daily inflows of that magnitude. The previous spike occurred in January as President Donald Trump took office, with two similar surges happening in November 2024 shortly after the U.S. elections.

The surge in inflows signals robust investor demand for direct bitcoin exposure through familiar financial vehicles. Spot bitcoin ETFs offer an accessible route for both retail and institutional investors, removing hurdles like crypto custody and regulatory uncertainty.

Meanwhile, President Trump’s media company has filed for a spot bitcoin ETF under the Truth Social brand, although it still awaits the Securities and Exchange Commission’s approval.

Several other crypto ETFs—including funds tracking Solana (SOL), XRP, and other tokens—are also pending regulatory clearance.
