June 2025 was a groundbreaking month for US spot Bitcoin and Ethereum Exchange Trade Funds (ETFs), collectively securing a fresh inflow of nearly $6 billion.
This impressive performance is one of the strongest shows of the year and reflects the growing institutional interest in cryptography.
According to data from Sosovalue, the Bitcoin-centric ETF raised $4.6 billion over a consistent 15-day inflow, raising the lion’s share of funds. This has resulted in a cumulative total of approximately $49 billion flows and a net worth of $134 billion.
Among these funds, BlackRock’s Ishares Bitcoin Trust (IBIT) distinguishedly drew $3.855 billion, making it the best-selling Bitcoin ETF and strengthened its position as the sector’s dominant player.
Meanwhile, the Ethereum ETF was the second-best performance since it launched in 2024, seeing a significant $1.1 billion of $1.1 billion in new capital.
Ethereum’s growth has largely resulted in increased scalability and security, due to continued institutional enthusiasm following the successful upgrade of Pectra. These Ethereum ETFs currently boast net inflows of $4.2 billion and assets of over $10 billion.
Crypto ETF Summer
The solid performance of Bitcoin and Ethereum ETFs has encouraged speculation that the SEC is poised to quickly approve additional cryptocurrency ETFs.
On June 30, Bloomberg analysts Eric Balknas and James Seyfert raised the approval odds for Solana, Litecoin and XRP ETFs to 95% by 2025, citing positive development in the regulatory environment and increased institutional demand.
Analysts predict that a new wave of ETF approvals will be seen in the second half of 2025, with the SEC likely to clear multiple crypto indexes and basket ETFs by early July.
Other Altcoins such as Dogecoin, Cardano, Polkadot and Avalanche are also on the radar, with analysts allocating a 90% chance of SEC approval by the end of the year.
The optimism surrounding these ETFs is largely attributed to the current US administration’s supportive stance under President Donald Trump, who defends Procrypt’s policy.
This change promotes the belief that the crypto market could enter a new era of growth and regulatory clarity.
