The Ark Innovation ETF now allocates 2.6% to BitMine, while the other two funds maintain similar positions. Altogether, ARK funds hold 6.7 million shares in the firm, valued at about $284 million, according to fund prospectuses.
BitMine stock responded positively, climbing 4.1% in after-hours trading to $44.10. The stock has soared nearly 460% since the beginning of the year according to Google Finance data.
BitMine Reaches Historic Ether Milestone
The investment came as BitMine announced its Ether holdings had crossed the 2 million ETH mark, valued at roughly $8.9 billion. This milestone makes BitMine the world’s largest Ether treasury, controlling 42% of the total ETH held by corporations currently 4.9 million ETH in aggregate.
Since April, the company has accumulated 1.7% of the entire Ether supply. BitMine’s long-term goal is to secure 5%, with current holdings representing only 34% of that target.
“We continue to believe Ethereum is one of the biggest macro trades over the next 10–15 years,”
said BitMine chairman Tom Lee.
Tom Lee Eyes Fed Rate Cut as Catalyst
Alongside the Ether announcement, Lee voiced optimism about potential Federal Reserve rate cuts. Speaking to CNBC, he highlighted that lower rates would reduce borrowing costs, particularly mortgages, and bolster business confidence.
Market indicators show traders widely expect the Fed to deliver a 25 basis point cut next week, with an 89.4% probability, while only a 10.6% chance remains for a larger 50-point move. Standard Chartered also now expects the Fed to slash rates by 50 basis points in September, doubling its previous 25 bps forecast.
