U.S.-based spot bitcoin exchange-traded funds (ETFs) faced a challenging start to 2025, recording substantial net outflows on January 2. Data from Sosovalue reveals that the 12 bitcoin ETFs collectively bled $242.30 million, with Blackrock's IBIT suffering the heaviest blow, losing $332.62 million in a single day — one of the largest withdrawals from the fund in recent months. Grayscale's GBTC mirrored the trend, shedding $23.13 million.
Five ETFs Buck the Trend
Despite the overall outflow, five bitcoin ETFs managed to attract capital, mitigating the impact of the losses from IBIT and GBTC. Bitwise's BITB led the pack with $48.31 million in net inflows, followed by Fidelity's FBTC ($36.20 million), Ark Invest and 21shares' ARKB ($16.54 million), Grayscale Bitcoin Mini Trust ($6.89 million), and VanEck's HODL ($5.51 million). Total trading volume for the bitcoin ETF complex stood at $3.24 billion on Jan 2.
Cumulative Inflows Remain Strong
Since the launch of spot bitcoin ETFs on January 11, 2024, the cumulative net inflows have reached $35 billion, underscoring sustained institutional appetite. As of Jan 2 close, the 12 funds collectively hold $109.43 billion in BTC, equivalent to 5.68% of the global bitcoin market capitalization. The single-day outflow, while notable, is viewed by analysts as a tactical repositioning rather than a structural reversal.
Ethereum ETFs Also Hit
The nine ether ETFs did not fare better, posting combined net outflows of $77.51 million. Bitwise's ETHW led the decline with $56.11 million in redemptions, while Grayscale's ETHE shed $21.4 million. The remaining seven ether ETFs recorded zero net flows. Daily trading volume for ether ETFs reached $397.23 million. Since their debut on July 23, 2024, ether ETFs have accumulated net inflows of $2.58 billion and manage total assets of $12.44 billion, representing 2.99% of ether's market cap.
Market Implications
The capital movements in both bitcoin and ether ETFs reflect evolving investor sentiment and strategic recalibrations amid shifting crypto market dynamics. While Blackrock's IBIT saw a significant withdrawal, the simultaneous inflows into other ETFs suggest a rotation rather than a wholesale exit from the asset class. Industry observers note that ETF flows remain a key barometer of institutional confidence in digital assets.
