4E: BlackRock Holdings exceed 700,000 BTC, encryption ETF demand far exceeds Miner supply

ChainCatcher news, according to 4E observation, the world's largest asset management company BlackRock's IBIT Bitcoin Spot ETF has seen a net inflow of $165 million this week, with holdings surpassing 700,000 BTC, and the current market capitalization is approximately $75.5 billion. Since its establishment in early 2024, this ETF has achieved a total return rate of 82.67%, currently accounting for over 55% of all BTC Spot ETF holdings in the United States. According to Galaxy Research, as of 2025, IBIT and American institutions such as MicroStrategy have collectively purchased approximately 28.2 billion USD worth of Bitcoin, while the new output from miners during the same period was only 7.85 billion USD, indicating that institutional demand continues to exceed the on-chain new supply, boosting the long-term fundamentals of BTC. In addition, the attitude of regulators is also becoming more lenient. The U.S. Securities and Exchange Commission (SEC) is studying the simplification of the ETF approval process, proposing to unify the application using the S-1 form and set a 75-day review period, which will automatically take effect if there are no objections. Earlier this month, REX-Osprey launched the first Solana ETF with staking rewards, marking the gradual expansion of ETF products to other categories of crypto assets. 4E reminds investors: The growth of institutional Holdings and signals of regulatory easing are reshaping the market structure, and it is necessary to continue monitoring the potential volatility brought about by ETF fund dynamics and policy evolution.
