BlackRock’s IBIT Bitcoin ETF has surged to become the dominant institutional vehicle in the US spot Bitcoin ETF market, holding over 636,000 BTC—more than double the combined amount held by all other US spot Bitcoin ETFs.
Since early 2024, IBIT has led capital inflows and Bitcoin accumulation, attracting heavyweight institutional investors such as Mubadala Investment Company, Citadel Advisors, and Avenir Group. This rapid ascent positions IBIT as the primary avenue for institutional Bitcoin exposure, while smaller ETFs grapple with declining liquidity and relevance, sparking concerns about market concentration and a potential monopoly.
CryptoQuant’s analysis highlights how IBIT’s considerable size enhances its appeal as the secure and trusted choice for allocators, further consolidating capital flows into a single dominant player. This mirrors market consolidation trends seen in other sectors, where trust gravitates toward the most recognized institutions. The growing reliance on IBIT raises fundamental questions about the long-term structure and competitive dynamics of the institutional Bitcoin market.
Institutional interest continues to evolve with notable expansions: Abu Dhabi’s Mubadala Investment Company increased its IBIT stake to 8.7 million shares in Q1 2025, Citadel Advisors tripled its holdings to roughly 3 million shares valued at $147 million, and Hong Kong’s Avenir Group grew its position to 14.7 million shares by March 2025.
This concentration of assets could reshape Bitcoin’s institutional narrative—potentially making BlackRock synonymous with Bitcoin exposure in the ETF realm, a development warranting close watch for its implications on market competition and investor choice.
