Deep Dive
1. Bitcoin ETFs With Outflows
US spot Bitcoin funds showing net outflows this week included IBIT (BlackRock), BITB (Bitwise), ARKB (ARK 21Shares), HODL (VanEck), GBTC (Grayscale), and BTC, while FBTC (Fidelity) posted net inflows. The weekly tally cited IBIT at about $240 million outflows; BITB around $115 million; ARKB near $100.7 million; HODL about $39.2 million; GBTC near $27.5 million; and BTC roughly $7.4 million, with FBTC up $33.1 million (fund-by-fund list).
Flows diverged by issuer. If you track liquidity and sentiment, monitor whether outflows persist across multiple sessions versus rotating into one or two funds.
2. Weekly Scale Of Outflows
At the broader product level, crypto ETPs saw approximately $952 million in net outflows this week, heavily concentrated in the US, per CoinShares weekly note. Ethereum-based products bore the largest share (about $555 million), with Bitcoin products around $460 million out (summary).
The report linked the pullback to regulatory uncertainty (Clarity Act delays) and selling pressure from large holders, a common driver when macro or policy signals turn ambiguous (summary).
Weekly outflows at this scale usually reflect sentiment cooling or policy noise. The context matters more than one days print.
3. Ether ETF Outflows (Daily Snapshot)
Ether ETFs were mixed during the week, but posted notable daily net outflows on 2324 Dec. Named funds with outflows included ETHE (about $50.89 million), ETHA ($25.04 million), ETHW ($13.98 million), and EZET ($5.61 million) in one daily read (daily flows snapshot).
Separately, Bitcoin ETFs also recorded daily outflows in the same window, with IBIT leading one sessions outflows (daily context).
Day-to-day prints can flip quickly. Use the weekly view for direction and the daily for timing, especially near holidays when liquidity is thinner.
Conclusion
Outflows this week were broad but uneven: several leading Bitcoin ETFs saw net redemptions while one major fund (FBTC) still attracted inflows. The weekly ETP outflow total near $952 million and Ether-heavy selling point to policy and sentiment headwinds rather than a single issuer issue. If outflows persist across multiple sessions and remain concentrated in the US, it could signal ongoing caution until regulatory clarity improves.
