Ethereum spot ETFs post highest monthly outflow of $1.4 billion in November, breaking seven-month streak

Meanwhile, ethereum developers are preparing for the activation of Fusaka, the next network upgrade.

Ethereum spot ETFs just saw their highest monthly outflow ever, losing $1.4 billion in November and breaking a seven-month streak of inflows. Cumulative net inflows now stand at more than $12.9 billion, data from SoSoValue shows. 

The outflows of the ethereum-focused investment funds were lower than bitcoin spot ETFs, which saw nearly $3.5 billion in monthly outflows. On the other hand, nascent ETFs of other cryptocurrencies, such as solana, dogecoin, XRP, and litecoin, saw positive inflows in November. 

After experiencing a relief rally during the Thanksgiving holiday that saw the price of ethereum return to above $3,000, the second-largest cryptocurrency has declined almost 9% in the last 24 hours.

Meanwhile, BitMine Immersion Technologies, the largest ethereum treasury firm, announced acquiring 96,798 tokens last week, bringing its total holdings of ethereum to 3.7 million tokens, per a Monday press release

Network upgrade coming soon

The developments come as ethereum developers are gearing up the next network upgrade, scheduled for activation on Wednesday. Dubbed “Fusaka,” it aims to improve the experience for both users and developers alike.

Ethereum’s network upgrade marks the second of 2025, with the last one occurring in May.

Fusaka focuses on strengthening ethereum’s core fundamentals rather than price action in the short term, per Sam Klehr, global head of business development at staking provider Chorus One.

Historically, upgrades that lower costs and improve performance support healthier long-term ecosystem growth: more applications, more activity, and more value settling on the network, Klehr told Sherwood News. Those underlying dynamics are what ultimately matter for ethereum’s valuation.

ETHZilla, one of the largest ethereum treasury firms, with around $262.7 million worth of tokens, says the Fusaka upgrade “strengthens Ethereum’s position as a high-capacity settlement layer capable of supporting compliant, institutional-grade tokenization at scale,” according to John Kristoff, ETHZilla’s senior vice president of investor relations.

“The upcoming Ethereum Fusaka upgrade represents a meaningful step forward for real-world asset tokenization,” Kristoff told Sherwood in an email. “Fusaka enables Layer-2 networks to process significantly more transaction data at lower cost while maintaining Ethereum’s security layer. This enhanced throughput and efficiency translates directly into more scalable, reliable, and economically viable infrastructure for tokenized assets.”

BlackRock’s IBIT on track for its worst month of net outflows, as investors yank $2.3 billion from the bitcoin ETF in November

BlackRock’s iShares Bitcoin Trust ETF, the world’s largest bitcoin fund, is heading for its worst month of outflows since it launched in January 2024.

Investors have pulled over $2.3 billion (net) throughout November so far. The jitters come as bitcoin grapples with its worst downturn since 2022, when the entire crypto world shook following the fall of Sam Bankman-Fried’s FTX — bitcoin has dropped more than 40% from its October high as of Monday’s close.

With their soaring popularity redefining and legitimizing cryptocurrencies at an institutional level, spot bitcoin ETFs have become a key barometer of wider investor sentiment surrounding the digital currency — as well as risk assets more broadly.

Notably, spot bitcoin ETFs like BlackRock’s iShares Bitcoin Trust tend to see their inflows accelerate with rising prices, and amplify falling prices when outflows become dominant. Citi Research, cited by Bloomberg, found that this feedback loop sees a ~3.4% price drop for every $1 billion pulled out from bitcoin ETFs.
