IBIT Sets A Record With 6.2 Billion Dollars In Revenue In May

BlackRock’s iShares Bitcoin Trust (IBIT) ETF recorded a total cumulative inflow of more than $6.2 billion from the beginning of May through May 29, 2025. This monthly record confirms the growing interest of investors in bitcoin through regulated financial vehicles, in an economic context marked by uncertainty.

A Historic Record for BlackRock’s Bitcoin ETF (IBIT)

At the heart of the financial revolution blending BTC and traditional finance, BlackRock’s Bitcoin ETF (IBIT) stands out as a flagship product. This publicly traded fund, launched in early 2024, shows unprecedented inflows. Never before has a Bitcoin ETF accumulated such a volume in less than six months. In May alone, IBIT attracted nearly $6.22 billion, far surpassing its previous record set in March 2024.

According to Nate Geraci, President of the ETF Store:

Nearly $9.5 billion have been invested in the iShares Bitcoin Trust ETF in 2025, with inflows on 30 of the last 31 days.

This dynamic demonstrates the scale and consistency of inflows into this fund.

Investments in BlackRock’s Bitcoin ETF have already reached a monthly record level, reflecting renewed confidence in BTC as an investment asset. Data from Farside Investors show that IBIT alone concentrates nearly 90% of total inflows into spot Bitcoin ETFs in the United States, reinforcing its dominant position in this highly competitive segment.

Implications for the Crypto Market

IBIT dominates a fragmented market where other Bitcoin ETFs stagnate or suffer outflows, illustrating investors’ strong preference for this product. This success is based on several strengths:

• BlackRock’s solid reputation, a source of trust;
• Competitive fees;
• High liquidity.

This dominance by IBIT influences the bitcoin market by generating constant buying pressure, which could support its valuation. It also encourages institutional adoption by providing regulated access to crypto and making bitcoin a safe-haven asset.

However, this concentration presents risks:

• Amplification of systemic risks;
• Increased regulatory scrutiny.

The rapid rise of BlackRock’s Bitcoin ETF (IBIT) makes BTC a major institutional asset. Nevertheless, this concentration raises questions about systemic risks and the role of regulators. With the prospect that companies could control 50% of bitcoins by 2045 , will BTC be able to preserve its independence in the face of the growing power of large institutions?
