Why is BitMine gaining attention
The firm has been in the news lately for its aggressive crypto-treasury strategy. The company has been building a very large Ethereum position and has moved from being a mining-focused firm to one with a sizable ETH treasury. The investment also highlighted on Tom Lee Tracker social media profile.

That shift and Tom Lee’s recent strategic investments in other firms pursuing crypto treasury plays appears to be one reason the firm increased its stake. Recent reports show the company sitting among the largest corporate holders of ETH, a fact that has pushed investor interest in BMNR.
At the same time ARK was buying BMNR, the firm trimmed some Robinhood Markets (HOOD) holdings. ARKW sold 43,728 shares of Robinhood, a trade that was valued at roughly $5.1 million at Monday’s close as Robinhood’s stock jumped after news it will be added to the S&P 500.

Currently company stock is trading at $117 with 16% high. The S&P inclusion caused a big pop in HOOD shares and may have created an opportunistic window for ARK to realize gains or rebalance exposures.
Part of the recent spotlight on BMNR comes from its strategic move into Eightco Holdings (OCTO), which announced a plan to adopt Worldcoin (WLD) as a treasury asset.

Its committed capital to Eightco’s private placement helping fuel a high-profile push into Worldcoin-related treasury strategy. Alongside BitMine purchased the share of $OCTO as a part of its Moonshot Strategy.
That news sent ripples through small-cap crypto-linked stocks and likely contributed to the narrative that professional investors are hunting corporate exposure to ETH and other crypto strategies. The move represents why Ark Invest buys BitMine shares.
The trades show ARK is extending its crypto-equity bets beyond exchanges and infrastructure into companies that hold digital assets on their balance sheets. Purchasing BitMine and selling Robinhood indicates a choice to rebalance away from a retail brokerage that just saw an intraday rise and to overweight pure-play ETH treasury exposure (via BMNR). Investors who follow Cathie Wood's news frequently take them as an indication of market exposure and an ongoing focus on next-generation financial bets and cryptocurrency.
