Arthur Hayes sells $22M in altcoins as ETH ETFs record over $1M in outflows in October

Arthur Hayes, an iconic figure in the sector and co-founder of the BitMEX exchange platform, announced that he has sold $22.28M worth of altcoins, including 6,400 ETH, citing macroeconomic and geopolitical fears. The move comes as Ethereum-backed exchange-traded funds (ETFs) record record outflows for October, a signal that observers are closely monitoring for institutional demand. Context Arthur Hayes is the Chief Investment Officer (CIO) of Maelstrom, an investment firm that manages a so-called "directional" strategy: it takes positions on the rise or fall of certain digital assets. His name is associated with BitMEX, a cryptocurrency derivatives platform he co-founded and which was for a long time one of the largest in the world, explaining the attention paid to his decisions. Spot ETFs, which actually hold the underlying token and track its price, have become a major channel of institutional demand for both bitcoin and ether since their launch in the United States. As of the publication date, the market remains under pressure: according to CryptoScore Pro data from October 25, 2026, at 06:04 UTC, bitcoin is trading at $80,472 and ether at $2,347.26, with the latter seeing a 2.64% decline over seven days. The Crypto Fear & Greed index shows 54/100, representing a sentiment qualified as neutral. The Facts According to the media outlet AMBCrypto, citing public statements from Arthur Hayes, Maelstrom primarily sold its ether, specifically 6,400 ETH valued at approximately $15.2M. Other positions sold include, according to the same source, $2.76M in Ethena (ENA) tokens, $2.24M in Uniswap (UNI), as well as positions in EtherFi (ETHFI), Aerodrome (AERO), and Zama, for a total of $22.28M. Hayes justified this decision by stating that the strategy had taken profits, while mentioning an "uncertain" macroeconomic and geopolitical situation. Several market context elements are reported by the same source. According to AMBCrypto, spot ether ETFs recorded $1.1 billion in net outflows in October 2026, nearly three times more than bitcoin ETFs, which saw $313 million in outflows. This would be the second highest month of outflows for these products since their inception, following the record of $1.42 billion recorded the previous November. The source also indicates that early Ethereum investors sold more than $8M in tokens in the 48 hours preceding the publication. Finally, the company Bitmine, which has been accumulating ether for its treasury since June, would hold 6.053 million ETH, or 99% of its goal of 5% of the supply. Some discrepancies deserve to be noted: the ETF outflow figures come from the editorial source and are not cross-referenced by CryptoScore Pro data, which do not cover these flows. Furthermore, the reference brief mentions a daily volume and a security score for Ethereum, as well as a tier-1 level audit and a MiCA registration, but these elements are not confirmed by the editorial source. Nor are the exact composition of the altcoins sold, the precise date of each transaction, and the share these sales represent in Maelstrom's global portfolio disclosed. Understanding Key Concepts Spot ETF An ETF (exchange-traded fund) is a financial product listed like a stock, which tracks the price of an asset. A "spot" ETF actually holds the underlying token: a spot ether ETF buys ether. When its investors withdraw money, the manager must sell ether, which mechanically weighs on demand. Market Capitalization Market capitalization is calculated by multiplying the price of a token by the number of tokens in circulation. With approximately $286.94 billion according to CryptoScore Pro, ether is ranked second behind bitcoin, whose capitalization reaches $1.62 trillion. Staking Staking consists of locking up tokens to participate in the validation of transactions on a "proof-of-stake" network in exchange for a reward. This reward is funded by the issuance of new tokens, which increases the circulating supply: this is why high staking can paradoxically increase pressure on the price. Liquidity and Volume Liquidity refers to the ease with which an asset can be bought or sold without significantly altering its price. The 24-hour trading volume, 8.79 billion dollars for ether according to CryptoScore Pro, is a simple indicator of this. Analysis: what is at stake The movement described by the source illustrates several classic price formation mechanisms in digital asset markets. The first is liquidity sensitivity: the sale of approximately $22.28M of altcoins by Arthur Hayes, according to the source text, represents a volume that, on lower-capitalization tokens, can weigh on prices in the short term. The second is institutional demand, which is notably channeled through exchange-traded funds (ETFs). According to the source, spot Ethereum ETFs recorded approximately $1.1B in outflows in October 2026, nearly three times the outflows seen in Bitcoin ETFs ($313M). A capital outflow of this magnitude removes a regular source of buying, which weighs on the balance between supply and demand. For the asset itself, the central issue is that of supply. According to the source, approximately 20,000 ETH are added to the supply each week, and the accumulation by the company Bitmine, which now holds 6.053M ETH, could stop at any time, as it has reached 99% of its goal. If this demand disappears while ETF outflows continue, selling pressure could intensify. For investors, this means that the price depends less on the technical strength of the network, which CryptoScore Pro data evaluates at 95.1/100, than on short-term capital flows. Three scenarios can be presented as hypotheses, without certainty. In the first, ETF outflows stabilize and the support located between 2,300 and 2,400 dollars holds. In the second, a deterioration of the geopolitical context leads to new sales and the price tests 2,200, or even 2,100 dollars, as mentioned by the source. In the third, an improvement in the macroeconomic climate or…
