- Ark Invest raises $148 million by trimming Coinbase and Roblox positions.
- Proceeds fund a $174 million purchase of Bitmine Immersion Technologies chaired by Tom Lee.
Ark Invest has executed a portfolio rotation this year, moving capital out of two United States equities and into a company that keeps its treasury in Ether. Filings Monday show Cathie Wood steering three exchange‑traded funds closer to the Ethereum economy without breaching mandates that bar direct crypto holdings. The shift signals that institutional demand for yield‑bearing Ether assets is gathering pace.

The trades covered Ark Innovation, Next Generation Internet and Fintech Innovation ETFs. Together the vehicles sold blocks in Coinbase and Roblox then used the liquidity to establish a new core position in Bitmine Immersion Technologies, a company that converts idle balance‑sheet cash into staked Ether.
Trim in equities, boost in Ether exposure
The three funds unloaded 218 986 Coinbase shares for around $90.5 million and 463 293 Roblox shares for roughly $57.7 million. Coinbase remains Ark Innovation’s second‑largest holding, so the sale looks like profit taking and weight control rather than a directional call. Roblox, still inside the top ten, has delivered a forty‑two percent year‑to‑date gain that Ark chose to crystallize.
Fresh cash then financed the purchase of 4.4 million Bitmine shares at an average of $39. This $174 million ticket grants each fund about a one‑and‑a‑half percent stake in the Ether treasury specialist. Bitmine swapped its own Bitcoin reserves for Ether in June after it reoriented its business toward corporate staking services. The stock has climbed more than four‑hundred percent year to date, yet Ark framed the entry price as justified by future fee income.
Why Bitmine appeals to Ark
Tom Lee, best known for macro research at Fundstrat, chairs Bitmine and argues that staking rewards create a bond‑like cash flow that equity investors understand. By owning Bitmine rather than Ether directly, Ark captures those rewards inside a regulated security that slots neatly into equity‑based ETFs. The structure avoids custody hurdles while still linking performance to Ethereum network activity.
Wood’s investment committee also points to the growing number of corporates now logging Ether as working capital, attracted by projected real yield of four to six percent. If that trend accelerates, Bitmine’s assets under management and its fee base could scale quickly. For Ark, the trade nudges overall portfolio crypto sensitivity toward Ether, complementing its existing Bitcoin ETF exposure and maintaining the firm’s reputation for early adoption of digital‑asset themes.
The rebalance leaves Tesla, Coinbase and Robinhood as Ark Innovation’s top three holdings, but the addition of Bitmine positions the funds to benefit if Ethereum outperforms in the next cycle.
