BlackRock's iShares Bitcoin Trust Sees $665.2 Million Inflows Amid Ether ETF Outflows
On October 19, 2026, BlackRock’s iShares Bitcoin Trust (IBIT) stood out in the cryptocurrency market by attracting $665.2 million in net inflows. This surge occurred on a day when several competing funds experienced losses, with Fidelity’s FBTC and Grayscale’s GBTC reporting outflows of $83.6 million and $54.9 million, respectively.
The total net inflow for US spot Bitcoin ETFs reached $526.7 million, primarily driven by IBIT's performance. In contrast, spot ether ETFs continued to struggle, posting $103.3 million in net outflows, which extended a trend of withdrawals that had seen approximately $320 million leave ether funds in the previous week.
The inflow into IBIT may signal strong institutional interest in Bitcoin, suggesting that larger investors might be strategically accumulating the asset. Meanwhile, the contrasting performance of Bitcoin and ether ETFs indicates a more cautious sentiment surrounding ether, with market dynamics currently favoring Bitcoin.
As of mid-October 2026, cumulative net inflows into US spot Bitcoin ETFs surpassed $56 billion, with BlackRock’s IBIT consistently capturing the largest share. Conversely, spot ether ETFs entered October with net outflows exceeding $950 million.
