Bitmine Immersion Technologies shifted its listing to the New York Stock Exchange (NYSE) main board and expanded its share buyback limit to $4 billion.

On April 9, blockchain outlet The Block Crypto reported Bitmine began trading on the NYSE that day. Trading on its previous venue, NYSE American, ended at the close on April 8.

The company also strengthened its shareholder return policy alongside the move. The board unanimously approved a plan to raise the 2025 share repurchase authorization from $1 billion to $4 billion. The revised programme includes repurchases already carried out.

The share buyback programme was first approved on July 25, 2025. Under a contract with U.S. investment firm Cantor Fitzgerald, Bitmine can repurchase shares in the open market under Rule 10b-18 of the Securities Exchange Act of 1934.

Tom Lee (톰 리), Bitmine's chairman, said in a statement on the move, "Bitmine has set an important milestone by stepping onto the NYSE's Big Board," adding, "The NYSE is the most authoritative exchange with a long history and stature." The company said the size of the buyback is one of the top 10 announced cases under Fundstrat's 2026 share repurchase rankings. The same category includes Alphabet, Meta and Apple.

The announcement also came alongside Bitmine's recent increase in Ethereum accumulation. The company bought an additional 71,252 ETH in the week ended April 5, lifting total holdings to 4,803,000 ETH. At current prices, the value exceeds $10 billion. It is the largest weekly purchase since last December.

Staked holdings also rose sharply. Bitmine said staked Ethereum totalled 3,334,637 ETH as of April 6. That is about $7.1 billion based on the company's indicated price of $2,123 per ETH. The company claimed it stakes more Ethereum than any institution worldwide.

Bitmine's pace of purchases appears to be accelerating. In a separate statement released on April 7, Lee said, "Bitmine has increased the pace of Ethereum purchases over the past four weeks," adding, "The base case is that Ethereum is in the final stage of a mini crypto winter."

This has allowed Bitmine to highlight, at the same time, an upgrade of its listing venue, a large-scale share buyback and an expansion of its Ethereum holdings. The market is watching whether the company will strengthen its position in the stock market while continuing to push an Ethereum-focused asset strategy.
