Ethereum News Today: ARK Invest Bets Big on Crypto's Supply Tightening Play

ARK Invest has significantly increased its exposure to the cryptocurrency sector by acquiring a total of $23.5 million in equity stakes in BitMine and Bullish. The purchases were made across three of the firm’s actively managed exchange-traded funds (ETFs): the ARK Innovation ETF (ARKK), the ARK Next Generation Internet ETF (ARKW), and the ARK Fintech Innovation ETF (ARKF). The ARKK ETF led the investment, acquiring 257,108 shares of BitMine and 81,811 shares of Bullish, while ARKW and ARKF collectively took up the remainder of the shares. The total investment in BitMine amounted to $16 million, and in Bullish, it was $7.5 million, according to trade disclosures released on Friday [1].

BitMine, a leading corporate holder of Ethereum (ETH), now controls approximately 1.5% of the total Ethereum supply, valued at over $8.1 billion. This makes it the largest corporate Ethereum treasury in the world. The firm has continued to aggressively accumulate ETH, with recent additions of 153,075 ETH over a 10-day period, pushing its holdings to 1.866 million ETH. BitMine reported that all of its Ethereum holdings were purchased with cash, with no use of leverage [3]. This accumulation has positioned BitMine as a key player in the ongoing supply dynamics of the Ethereum market, as institutional activity continues to reduce available liquidity.

Bullish, which operates a global cryptocurrency exchange and owns CoinDesk, also saw significant investment from ARK Invest. The firm went public in August with a $1.1 billion initial public offering (IPO), after initially pursuing a SPAC merger that was later abandoned. ARK Invest was a major buyer on the first trading day, purchasing $172 million worth of Bullish shares. On Friday, Bullish shares rose 6%, continuing their upward trend from the IPO debut. However, the stock experienced a 1.5% decline in after-hours trading [1]. ARK Invest’s continued investment in Bullish indicates a strategic interest in expanding its portfolio within the cryptocurrency infrastructure sector.

Alongside its increased exposure to BitMine and Bullish, ARK Invest also reduced its positions in other tech stocks such as DraftKings, Roku, Roblox, and Teradyne. This move reflects a broader portfolio reallocation strategy, where the firm is emphasizing crypto-related equities at the expense of certain non-crypto technology investments. This strategic shift aligns with Cathie Wood’s long-term bullish stance on the role of blockchain and digital assets in the global financial landscape [2].

The growing trend of corporate Ethereum accumulation is not limited to BitMine. According to recent data, corporate Ethereum treasuries have now reached a combined value of $13 billion. Yunfeng Financial, a company associated with Alibaba founder Jack Ma, recently acquired 10,000 ETH, while The Ether Machine secured $654 million in private financing to amass 150,000 ETH. This institutional buying activity is further tightening Ethereum’s supply and reducing the amount of liquid ETH available in the market [5]. BitMine’s aggressive accumulation of 373,000 ETH in a single week—valued at nearly $1.6 billion—has also contributed to this supply squeeze, raising concerns about the potential for a significant supply shock in the future.

ARK Invest’s latest moves highlight a broader trend in the financial markets where institutional investors are increasingly viewing cryptocurrencies and related equities as strategic long-term investments. BitMine’s substantial Ethereum holdings and Bullish’s growing influence in the cryptocurrency exchange space reflect the growing institutional adoption of crypto assets. As the market evolves, the interplay between corporate Ethereum treasuries, ETF activity, and institutional buying patterns will likely remain a key driver of Ethereum’s price dynamics and broader market sentiment.
