In a sign of cautious optimism, the free fall of exchange-traded funds (ETFs) focused on spot Bitcoin and Ethereum appears to have stabilized by mid-December 2025. Despite still grappling with the repercussions of an exceptionally bearish November, which saw significant losses across the board, there is renewed interest from investors.
Data from SoSoValue reveals that Bitcoin ETFs alone garnered $198 million in inflows during December. Notably, BlackRock’s IBIT ETF led the charge, showing substantial growth in its assets under management. Within just 13 days, IBIT’s total holdings inflated from $66.26 billion to approximately $70.12 billion, reflecting a nearly $4 billion increase. Currently, Bitcoin ETFs hold over $118 billion in allocated assets, accounting for about 6.57% of Bitcoin’s overall market capitalization. IBIT now comprises about 60% of the Bitcoin ETF market, significantly outpacing competitors such as Fidelity’s FBTC and Grayscale’s GBTC.
On the Ethereum side, the numbers are even more striking. Ethereum spot ETFs attracted $143.35 million in December, with BlackRock’s ETHA emerging as a dominant player in this category. This revival comes in stark contrast to the previous month, wherein Ethereum ETFs experienced an unprecedented loss of $1.42 billion. Bitcoin ETFs were not spared either, facing a $3.48 billion outflow, marking one of the most challenging months in their history.
Investor sentiment shifted dramatically following a sharp flash crash on October 10-11, which contributed to the pessimism surrounding both cryptocurrencies. The lackluster performance of Bitcoin and Ethereum during that period prompted concerns that the market may have reached its peak cycle.
Despite these setbacks, indicators are beginning to reflect a potential turning point. Late November saw ETF performance slump to multi-month lows, but early December has ushered in signs of recovery. As both Bitcoin and Ethereum spot ETFs gradually recover, market participants remain tentatively hopeful that this trend will continue, signaling a potential reinvigoration of investor confidence in the cryptocurrency space.
