The institutional investment was spread across three ARK funds. The flagship ARK Innovation ETF acquired 67,700 BitMine shares, representing the largest portion of the purchase. The ARK Next Generation Internet ETF added 21,890 shares to its portfolio.

The ARK Fintech Innovation ETF completed the buying spree with 12,360 shares. Combined, the three funds now control 6.7 million BitMine shares valued at $284 million total.

ARK has been building its BitMine position since April when the company began its Ethereum accumulation strategy. The investment firm sees long-term value in corporate cryptocurrency treasury plays.

BitMine shares responded positively to the news, gaining 4.1% to close at $43.79. Extended trading pushed the stock higher by another 0.71% to $44.10. The company has delivered explosive 460% returns to shareholders this year.

BitMine Dominates Corporate Ethereum Market

BitMine’s 2 million ETH achievement establishes it as the undisputed leader in corporate Ethereum holdings. The company accumulated this massive position in just five months since pivoting from Bitcoin mining to Ethereum treasury management.

Chairman Tom Lee said BitMine now controls 1.7% of Ethereum’s total circulating supply. The company holds an even more dominant 42% share of all corporate ETH holdings across the entire industry.

Total corporate Ethereum holdings across all companies currently stand at 4.9 million tokens. BitMine’s outsized position reflects its aggressive accumulation strategy and early adoption of ETH as a treasury asset.

The company targets owning 5% of Ethereum’s total supply as its ultimate goal. Current holdings represent 34% progress toward that ambitious target, suggesting continued buying ahead.

Trading Activity and Market Outlook

ARK Invest balanced its BitMine purchase by selling Robinhood stock worth $5.13 million. The ARK Next Generation Internet ETF offloaded 43,728 Robinhood shares as the brokerage stock soared 15.8% to $117.28.

Robinhood’s rally followed S&P Global’s announcement that it would add the company to the prestigious S&P 500 index. This development prompted ARK to take profits on its long-held position.

Federal Reserve policy expectations continue supporting cryptocurrency markets. Futures contracts show 89.4% probability of a 25 basis point interest rate cut next week. There’s also a 10.6% chance of a larger 50 basis point reduction.

Lee expressed optimism about Fed rate cuts boosting business confidence and supporting both equity and crypto markets. Lower interest rates typically benefit risk assets like cryptocurrencies and growth stocks.

Ethereum prices have traded sideways this month despite BitMine’s milestone achievement. The token currently changes hands around $4,364, stuck in a tight trading range.

BitMine continues executing its accumulation strategy regardless of short-term price movements. The company views Ethereum as one of the biggest macro investment opportunities over the next 10-15 years.
