BlackRock's Bitcoin ETF investments surpass previous monthly records.
The iShares Bitcoin Trust (IBIT), an exchange-traded fund managed by BlackRock, has experienced a record-breaking month, amassing over $6.22 billion in investments in May 2025. This marks the largest monthly inflow in the history of the ETF, which has established itself as a dominant player in the spot Bitcoin category.
Investments in IBIT surged Wednesday, with nearly $500 million pouring into the fund, according to data from U.K. asset manager Farside Investors. Remarkably, IBIT has received net inflows every day this month except one. Nate Geraci, president of investment advisor ETF Store, called the inflows "ridiculous" in a tweet on May 29, 2025.
Institutional and retail investors have flocked to crypto ETF funds, driven by a more favorable political climate for digital assets in the U.S. and the growing acceptance of Bitcoin as a safe haven and legitimate investment asset. This trend is evident in IBIT's inflows, which amount to nearly 90% of all spot Bitcoin ETF flows.
The fund reached a May high of $877 million in investments on May 22, 2025, and more than $3.8 billion over the past eight days. U.S.-listed spot crypto ETFs as a whole have had inflows of $6.74 billion for the month. Overall, IBIT is responsible for all spot crypto ETF net inflows in May and for all of 2025, according to Sumit Roy, senior analyst at Etf.com.
The heightened interest in Bitcoin has helped send its price higher. As of the writing, Bitcoin was trading at approximately $106,500, down about 1% over the past 24 hours. However, it is up almost 12% for the past month, according to data from CoinGecko. The largest crypto by market value hit a record high above $112,000 on May 22, 2025, a day after U.S. President Donald Trump held a private White House dinner with 220 crypto investors who held his meme coin.
It's worth noting that the South Asian country, Pakistan, is establishing its own Bitcoin strategic reserve, and Trump Media recently announced plans to raise $2.5 billion to invest in the token. These developments underscore the growing interest in Bitcoin as an investment asset within traditional financial markets, with BlackRock's IBIT being a primary beneficiary of this trend.
