Bitcoin (BTC-USD) advanced 3.1% to $82,420 on Friday, settling above the technically important $80,000 level for the eighth consecutive session, as BlackRock's iShares Bitcoin Trust (IBIT) crossed $90.4 billion in assets under management. IBIT recorded $487 million of net subscriptions on Thursday — its 14th consecutive session of positive flow — extending what is now the longest inflow streak among all eleven U.S.-listed spot Bitcoin ETFs since their January 2024 inception.
Aggregate spot Bitcoin ETF AUM rose to $158.6 billion across the eleven funds, with IBIT capturing 57.0% market share — its highest concentration since November 2025. Fidelity's FBTC retained second place at $26.1 billion (16.5% share), followed by Grayscale's GBTC at $17.8 billion. The 14-session BlackRock streak coincided with $4.3 billion of cumulative net flow into IBIT alone — equivalent to approximately 53,000 BTC at the volume-weighted entry price of roughly $80,400.
