Live updates: Bitcoin ETFs take $731 million, their biggest day since January

Institutional capital flooded back into U.S. spot Bitcoin exchange-traded funds on Thursday, driving $731 million in net daily inflows—the largest single-day tally recorded since late January. The massive influx propelled total net assets across the entire ETF complex past the $103 billion threshold for the first time in history. Every fund in the 11-ETF lineup logged gains of nearly 6% during the session, reflecting an aggressive, broad-based rally that closely tracked a sharp upward expansion in underlying spot market prices. BlackRock’s iShares Bitcoin Trust (IBIT) once again served as the primary engine for the surge, capturing well over half of the day’s total net allocations. IBIT’s ongoing dominance underscores a structural reality in digital asset infrastructure: institutional allocators overwhelmingly favor the world’s largest asset manager due to its deep secondary market liquidity, tight bid-ask spreads, and established clearing networks. While competing products from Fidelity, Ark Invest, and Bitwise absorbed respectable secondary flows, BlackRock’s fund continues to act as the central valve through which traditional finance channels its digital asset exposure. The sudden velocity of these inflows points to a distinct shift in macro sentiment. Following weeks of range-bound consolidation and muted order books, fund managers appear to be re-engaging with crypto assets as part of a broader re-risking strategy. With global central banks maintaining an accommodative lean and sovereign debt concerns lingering in the background, Bitcoin is increasingly being traded as a high-beta, non-sovereign macro hedge. Furthermore, the creation-redemption mechanics behind these ETFs mean that sustained inflows force authorized participants to purchase physical Bitcoin directly from spot markets, stripping liquidity from OTC desks and exchange order books. Surpassing $103 billion in total net assets within such a compressed timeframe highlights the structural shift occurring within global capital markets. Spot Bitcoin ETFs have achieved an asset density in months that historically took traditional commodity vehicles years to realize. As institutional wealth platforms, pension funds, and RIA networks systematically integrate these products into standard model portfolios, the underlying supply dynamics of Bitcoin become increasingly constrained. If daily inflows remain near these historic levels, the reduction in liquid supply could catalyze further price appreciation, tightening Wall Street's grip on the asset's spot market structure.
