Ark Invest Buys the Dip as BitMine Expands Its Massive Ethereum Treasury
Ark Invest is once again leaning into its high-conviction strategy on blockchain infrastructure — this time by increasing its stake in BitMine, a firm rapidly positioning itself as the world’s largest Ethereum treasury holder.
The move came during a volatile week for crypto equities, as Ark purchased nearly a quarter of a million BitMine shares, worth around $9 million, across three of its ETFs. While most investors were selling into weakness, Cathie Wood’s team quietly turned the pullback into an entry point.
Buying Into the Dip
BitMine shares have been on a rollercoaster. After soaring over 700% since June, the stock has dropped sharply over the past month, falling more than 40% amid a broader selloff in crypto-linked companies. On Thursday alone, BMNR tumbled nearly 10%, closing at $37.37, though it briefly recovered 1% in pre-market trading the next day.
Instead of trimming exposure, Ark expanded it. The Ark Innovation ETF (ARKK) absorbed the biggest chunk, purchasing 167,348 shares, followed by the Next Generation Internet ETF (ARKW) and Fintech Innovation ETF (ARKF), which took 48,361 and 24,798 shares respectively.
The additions keep BitMine within Ark’s top 15 holdings across multiple funds — a significant commitment given the firm’s strict diversification rule that caps any single position below 10% of total fund assets.
Ethereum Treasuries Emerge as a New Asset Class
What makes BitMine unusual is its balance sheet. Instead of traditional cash reserves, the company’s treasury strategy revolves around Ethereum accumulation. Under the guidance of Tom Lee and backed by heavyweight investors like Ark Invest, Bill Miller III, Galaxy Digital, Kraken, Pantera Capital, and DCG, BitMine’s ambition is to own 5% of the entire ETH supply — roughly 6 million coins.
So far, it’s already more than halfway there. The firm added 82,353 ETH last week, bringing total holdings to 3.4 million ETH, currently valued at over $11 billion. That scale makes BitMine the largest Ethereum treasury entity in existence — bigger than SharpLink or The Ether Machine — and the second-largest corporate digital asset holder globally, behind only Michael Saylor’s Strategy, which owns 641,205 BTC.

Thursday’s plunge wasn’t isolated. Other publicly traded crypto plays — Coinbase (-7.5%), Robinhood (-10.8%), and Strategy (-7%) — also fell, while miners like IREN and treasury competitor SharpLink sank even further. Bitcoin itself slipped 2.3%, Ether 3.4%, and the broader GMCI 30 index lost a similar margin.
Yet Ark’s move suggests it sees the selloff less as risk, more as rotation. The firm has historically treated volatility as a buying window — and this latest trade extends that philosophy into the fast-growing Ethereum treasury narrative.
Long-Term Conviction in Blockchain Balance Sheets
Ark’s sustained exposure to BitMine reflects a bet not just on one company, but on a new kind of corporate structure — one where blockchain assets replace traditional reserves. Wood’s thesis has long been that digital treasuries will become a defining feature of next-generation finance, mirroring how corporate Bitcoin holdings reshaped balance sheet strategy earlier this decade.
With BitMine now holding a portfolio larger than many national banks’ gold reserves, Ark’s timing may again prove prescient. The firm’s purchase during one of BitMine’s weakest months could position it to benefit from a rebound if Ethereum prices recover or institutional adoption accelerates into 2026.
For Ark, this isn’t just buying the dip — it’s doubling down on a vision where corporate treasuries live on-chain.
