BlackRock’s IBIT poised to set fastest path to $100B AUM

BlackRock’s IBIT sits near $100B AUM and is set to break the speed record, contingent on closing above the threshold.

BlackRock’s iShares Bitcoin Trust (IBIT) is approaching the $100B AUM mark and—if it closes above it—would set a speed record for ETFs reaching that level.

Numbers and pace

Launched in January 2024, IBIT has scaled to the threshold in under two years, surpassing the multi-year timelines typical of prior large ETFs.

Structure and mechanics

IBIT is a spot Bitcoin ETF. Primary market creations/redemptions occur in-kind with BTC via authorized participants, so sustained net creations reflect incremental coin demand alongside price effects.

Market context

Strong, recurring inflows into U.S. spot Bitcoin ETFs, institutional adoption, and IBIT’s liquidity advantages have reinforced a flywheel of tighter spreads and deeper depth relative to peers.
