With this move, ARK’s total investment in the Ethereum-focused firm has now surpassed $300 million.
BitMine, regarded as a proxy for Ethereum exposure due to its $7.5 billion ETH holdings, now represents nearly half the value of ARK’s investment in Coinbase (COIN), where ARK holds about $676 million despite a recent trim of 5,721 shares.
ARK’s accumulation of BitMine shares began on July 21 with a $174 million purchase, followed by $17 million more on August 2.
The strategy reflects ARK’s high-conviction bets in blockchain and digital assets.
Beyond BitMine, ARK also added $21.2 million in Bullish stock and $16.2 million in Robinhood shares, with the latter now valued at $543 million.
Despite this vote of confidence, BitMine stock fell 8% Wednesday, though it remains up 490% year-to-date, supported by strong earnings growth.
