BlackRock's Bitcoin Now Rivals Its Gold ETF in Size

BlackRock's IBIT Bitcoin ETF has grown to rival the firm's IAU gold ETF. What happens when the world's largest asset manager treats Bitcoin as a store of value?

BlackRock manages over $10 trillion in assets. When it launched its Bitcoin ETF (IBIT), it crossed $50B in AUM faster than any ETF in history. By mid-2025, IBIT was approaching parity with IAU, the firm's flagship gold ETF. This is seismic for institutional crypto adoption.

The Store-of-Value Thesis, Validated

Bitcoin advocates argued for years that BTC would capture a portion of gold's $13 trillion market cap. BlackRock's IBIT growth is the first concrete evidence that institutional capital is making that shift at scale.

Impact on DeFi

As more capital flows into Bitcoin, the entire crypto ecosystem benefits: higher BTC prices mean higher collateral values, more venture funding for protocols, and greater public interest in learning about DeFi.
