BitMine’s stock responded positively to the news, closing up 4.1% at $43.79 and gaining an additional 0.71% in after-hours trading. The company’s shares have performed exceptionally well in 2025, rising 460% since the beginning of the year.
The timing of ARK’s investment coincided with BitMine’s announcement that its Ethereum holdings have surpassed the 2 million ETH mark, valued at approximately $8.9 billion at current prices. This achievement comes just five months after BitMine began accumulating ETH as a treasury asset in April.
BitMine’s Dominant Position in Corporate ETH Holdings
BitMine has quickly established itself as the world’s largest corporate holder of Ethereum. The company now controls 1.7% of the total ETH supply and accounts for 42% of all corporate Ethereum holdings, which currently stand at about 4.9 million ETH.
Tom Lee, BitMine’s chairman, expressed strong confidence in Ethereum’s long-term prospects. “We continue to believe Ethereum is one of the biggest macro trades over the next 10-15 years,” Lee stated. The company appears committed to its acquisition strategy, having reached only 34% of its target to acquire 5% of the total Ethereum supply.
While BitMine continues its aggressive ETH accumulation, the price of Ethereum itself has remained relatively stable during September, trading within a narrow range around $4,356.
Federal Reserve Decision and Market Outlook
In related market news, Tom Lee also shared his outlook on the upcoming Federal Reserve interest rate decision. Lee told CNBC that he expects a rate cut next week, which he believes will have “dual positives” for the economy.
Fed cutting interest rates will have dual positives of:
– lowering interest rates, particularly mortgage rates could fall (spread to 10Y)
– boosting biz confidence as ISM below 50 for a record 31 months
This is why a Fed cut in Sept will be supportive of equities, particularly… https://t.co/Y9dQl92o5b

“Fed cutting interest rates will have dual positives of lowering interest rates, particularly mortgage rates could fall, [and] boosting business confidence,” Lee explained. He predicted these changes would benefit equities, especially small-cap stocks, as well as cryptocurrencies.
Current futures prediction markets align with Lee’s expectations, indicating an 89.4% probability of a 25 basis point cut and a 10.6% chance of a larger 50 basis point reduction.
While increasing its position in BitMine, ARK Invest made other portfolio adjustments. The company sold $5.13 million worth of Robinhood Markets (HOOD) shares from its ARK Next Generation Internet ETF as Robinhood’s stock surged 15.8% following the announcement of its addition to the S&P 500 index.
ARK’s continued investment in BitMine reflects growing institutional interest in companies with exposure to cryptocurrency assets. The firm has been gradually increasing its BitMine position since April when the company first began building its Ethereum treasury.
BitMine shares traded at $44.10 in after-hours activity on Monday, continuing their upward momentum as investors respond to both ARK’s increased stake and the milestone in ETH holdings.
