- BlackRock’s IBIT surpasses 700K BTC, now holds 55% of U.S. spot Bitcoin ETF supply.
- Institutional Bitcoin buys outpace mining supply in 2025, per Galaxy Research data.
- SEC eyes streamlined crypto ETF approvals amid rising demand for staked asset exposure.
BlackRock’s iShares Bitcoin Trust (IBIT) has surpassed a major record, now holding over 700,000 BTC, solidifying its position as the largest spot Bitcoin ETF in the United States. The ETF crossed the limit following a $164.6 million inflow on Monday, bringing its total holdings to 700,307 BTC, worth approximately $75.5 billion.
According to Apollo co-founder Thomas Fahrer, the fund added 1,388 BTC in just two trading sessions. BlackRock’s iShares website had listed 698,919 BTC under IBIT as of Thursday, confirming the sharp increase. IBIT now represents over 55% of the total BTC held across all U.S. spot Bitcoin ETFs.
Data compiled by Galaxy Research shows that U.S. spot Bitcoin ETFs, in combination with corporate holdings such as those owned by Michael Saylor’s Strategy, are acquiring more Bitcoin than is currently being mined. As of 2025, these entities have collectively purchased $28.22 billion worth of Bitcoin, while miners have introduced only $7.85 billion in net new issuance.
This trend has remained consistent throughout the year, with one exception in February when net outflows from these entities totaled $842 million. Every other month, institutional purchases outstrip the newly mined supply. The ongoing accumulation signals continued institutional interest in Bitcoin exposure through regulated financial products.
IBIT Performance and ETF Revenue Shift
Since its launch in January 2024, the iShares Bitcoin Trust has recorded a total return of 82.67%. The ETF’s performance has led to notable changes in BlackRock’s internal fund dynamics. According to recent reports, revenue generated from IBIT has now surpassed that of the firm’s long-standing flagship equity fund, the iShares Core S&P 500 ETF.
This revenue shift points to rising investor interest in digital assets within traditional financial structures. The IBIT’s size and performance have elevated its prominence among the growing number of spot crypto ETFs currently active in the U.S. market.
Regulatory Developments in the ETF Approval Process
Following the increased operations in the crypto ETF space, the U.S. Securities and Exchange Commission is said to be making modifications to ease the approval process for future crypto-related ETFs. The amended regime would enable issuers to file Form S-1 and wait 75 days before actual objections are raised. Without any raised, the ETF may end up on the list.
This follows the introduction of the REX-Osprey Solana and Staking ETF earlier this month, the first U.S. ETF to provide exposure to a staked crypto asset. The product will offer exposure to Solana (SOL) and its staking rewards, which telegraph increased regulatory acceptability of more sophisticated crypto-based investment products.
