BitMine makes 2026's biggest Ethereum buy, lifting holdings to 5 million ETH

According to CoinMarketCap, Tom Lee's BitMine has executed the largest Ethereum purchase of 2026, pushing its total holdings to 5 million ETH. The buying spree is positioned as part of a hedging strategy that uses Ethereum to offset market swings tied to the U.S.-Iran conflict. With the latest acquisition, BitMine now controls more than 4% of Ethereum's total supply. Bitcoin's market all-time high has seen little impact, but BitMine's Ethereum position is large enough to become a standalone factor for ETH pricing. In derivatives sentiment, Polymarket's contract on Ethereum hitting $4,000 by April 30 was priced at 15% "Yes", with six days left until expiry. While the contract's face value has not changed, BitMine's purchase volume has been cited as shifting trader expectations, feeding speculation that broader institutional investors may also be accumulating ETH. BitMine's so-called "5% Alchemy" approach frames Ethereum as a corporate asset during periods of geopolitical uncertainty and could prompt similar strategies among other institutions. At $0.15 per share, a "Yes" position would pay $1 if Ethereum reaches $4,000 before April 30, implying a 6.67x return. For that wager to work, traders would likely need a near-term catalyst, whether from market reactions to geopolitical developments or other triggers. Key items to watch include Ethereum network upgrade announcements, large institutional inflows, comments from Vitalik Buterin, and Federal Reserve meeting minutes that hint at potential rate cuts. Any of these could move the contract in the remaining days.
