Bitmine began trading on the New York Stock Exchange on Thursday after moving from the NYSE American. At the same time, the company raised its repurchase authorization to $4 billion from $1 billion. The changes came as Bitmine expanded its ether treasury strategy under Chairman Tom Lee.
Shares fell 2.8% in early Thursday trading, and the stock remains about 90% below last summer’s peak. The company said the enlarged buyback ranks among this year’s biggest authorizations.

Bitmine paired the uplisting with a treasury plan centered on ether rather than bitcoin. It now holds about 4.8 million ETH, equal to 3.98% of total supply.
Management continues to target 5% of the Ether supply through what it calls the “Alchemy of 5%.” That goal links the stock closely to the Ether price changes and treasury growth.
Tom Lee chairs Bitmine and tied recent market moves to easing geopolitical tensions. He said U.S. equities may have found a bottom after a ceasefire related to Iran.
Stocks, oil, and volatility moved sharply after that development, and crypto prices also climbed. Those shifts formed part of a broader risk-on trade across markets.
Bitcoin recently traded above $72,000 while equity futures also advanced. Lee said Ether may also gain support from ETF inflows and heavier staking.
He said those trends can reduce selling pressure in the market. That setup matters for Bitmine because its treasury value moves with ether.
Ether gains directly affect Bitmine’s balance sheet because of the size of its holdings. The company said each 1% rise in ether adds about $100 million in value.
That exposure places Bitmine among the largest public holders of ether. Its current reserve equals nearly 4% of the token’s total supply.
The NYSE listing gives Bitmine a larger exchange venue as it pursues that target. The transfer took effect on Thursday, according to the company’s statement.
Bitmine announced the larger repurchase plan on the same day as the new listing. The authorization increased by $3 billion to a total of $4 billion.
The company framed the move as part of its capital strategy. It also said the buyback stands among the largest announced this year.
Bitmine’s shares have fallen sharply since last summer’s treasury-trade surge. Thursday’s early decline left the stock down about 90% from that earlier high.
Bitmine still aims to reach 5% of the ether supply. It now holds about 4.8 million ETH, or 3.98%, according to the company.
