Ethereum, the decentralized open-source blockchain, celebrated its 11th birthday on Thursday.

Cathie Wood's Ark Invest marked the occasion by trimming 120,665 shares of Bitmine Immersion Technologies Inc (NYSE:BMNR) on Wednesday—the world's largest corporate Ethereum treasury.

The trim came after firm recently described Bitmine's Ethereum treasury strategy as an "exponential opportunity" looking into 2026.

Ark also reduced positions in crypto-linked names Bullish (NYSE:BLSH), Block Inc (NYSE:XYZ) and Robinhood Markets Inc (NASDAQ:HOOD), marking a notable shift from Wood's recent pattern of buying crypto-related weakness.

On the other side of the ledger, the firm added to Space Exploration Technologies Corp (NASDAQ:SPCX), Taiwan Semiconductor Manufacturing Co Ltd (NYSE:TSM), Kratos Defense & Security Solutions Inc (NASDAQ:KTOS), BWX Technologies Inc (NYSE:BWXT), X-Energy Inc (NASDAQ:XE) and Tesla Inc (NASDAQ:TSLA).
