BlackRock’s iShares Bitcoin Trust Shatters ETF Growth Record, Surpassing $70 Billion in Just 341 Days

BlackRock’s iShares Bitcoin Trust (IBIT) has officially made history. The Bitcoin ETF surged past $70 billion in assets under management (AUM), reaching the milestone in just 341 trading days. This achievement makes IBIT the fastest ETF to ever hit that threshold.

To put that into perspective, the previous record-holder—SPDR Gold Shares (GLD)—took 1,691 days to reach the same milestone. “5x faster than the old record held by GLD of 1,691 days,” Bloomberg ETF analyst Eric Balchunas wrote in a post on X. Other ETFs like VOO (1,701 days), IEFA (1,773 days), and IEMG (2,063 days) also lag far behind IBIT’s rapid growth.

The explosive rise in IBIT’s AUM coincides with Bitcoin’s continued rally. At the time of reporting, Bitcoin (BTC) is trading above $108,000, up more than 2.06%, and sitting just under 4% below its all-time high of nearly $112,000 set last month.

BlackRock’s accumulation strategy has placed it at the forefront of institutional Bitcoin investment. According to blockchain analytics firm Arkham Intelligence, the firm now holds over 663,000 bitcoin—more than Michael Saylor’s MicroStrategy, which famously owns 582,000 BTC.

The price surge and ETF milestone reflect a broader institutional embrace of Bitcoin as a legitimate and increasingly preferred asset class. The record breaking pace of IBIT’s growth underscores the demand from investors looking for regulated exposure to Bitcoin through traditional financial products.

The chart clearly visualizes the disparity in ETF adoption timelines, with IBIT’s steep, vertical ascent dramatically outpacing its peers in the race to $70 billion. It’s a testament to the accelerating pace at which capital is flowing into Bitcoin markets.

As Bitcoin continues to hold just below its peak, and institutional products like IBIT grow at unprecedented speeds, all eyes are on what comes next—not just for Bitcoin, but for the legacy financial industry now being reshaped by it.
