Bitmine Immersion Technologies has started trading on the New York Stock Exchange under the ticker BMNR, marking a significant transition from NYSE American as of April 9, 2026. On the same day, the company announced a major expansion of its share repurchase authorization, now set at $4 billion, one of the largest buybacks seen in 2026 to date.
Founded in 2018, Bitmine focuses on large-scale digital asset accumulation and blockchain infrastructure, primarily leveraging immersion cooling technology to enhance mining efficiency. In recent years, the company has gained attention for its aggressive accumulation of Ethereum as a core treasury asset, aiming to become a major player within the crypto sector and public equity markets.
Bitmine joins NYSE main board with major buyback
After concluding trading on NYSE American on April 8, Bitmine’s common stock transitioned to the NYSE, positioning it among more prominent publicly traded firms. The company’s leadership highlighted this move as another step toward broader visibility in the capital markets.
Thomas Lee, who chairs Bitmine’s board, commented on the milestone, underlining both the symbolic and practical importance of joining the NYSE’s main listing. He emphasized the exchange’s history and significance in global finance in statements marking the event.
Today, Bitmine achieved a major milestone by being uplisted to the ‘Big Board’ NYSE. The NYSE is the most prestigious venerable stock exchange with a storied history. The NYSE is the envy of capital markets around the world and Bitmine is proud to be the newest company traded on this exchange.
Chris Taylor, Chief Development Officer at NYSE Group, formally welcomed Bitmine to the exchange, noting the company’s focus on Ethereum ecosystem development as a strong addition to the NYSE community.
Bitmine’s board approved the $4 billion repurchase program, originally established in July 2025 and now expanded in both scope and potential impact. Fundstrat’s recent report highlights this buyback as one of the ten largest announced by any corporate entity in 2026.
The company’s decision to expand its buyback authorization reflects an ongoing commitment to capital return, with leadership indicating readiness to retire shares should market prices fall below perceived intrinsic value.
Ethereum accumulation and institutional backing
As of April 6, 2026, Bitmine holds around 4.803 million ETH, which accounts for 3.98% of all Ethereum in circulation. This accumulation forms part of Bitmine’s “Alchemy of 5%” target, with progress now surpassing 79% toward its goal to control 5% of the entire ETH supply within just nine months.
The company’s total assets, spanning cryptocurrency, cash, and other holdings, now reach approximately $11.4 billion. Cash reserves alone stand at $864 million, while other crypto assets are grouped under an internally branded “Moonshots” category.
Bitmine’s Ethereum acquisition strategy continues to attract sizable institutional investment. Notable backers include ARK Invest’s Cathie Wood, Founders Fund, Pantera Capital, Kraken, DCG, Galaxy Digital, MOZAYYX, and Bill Miller III.
Chairman Lee explained the rationale for expanding the repurchase plan, pointing to flexibility in capital allocation as a key priority for both the company and its long-term shareholders.
Bitmine’s expanded $4 billion buyback reflects our commitment to shareholders. There may be a time in the future when Bitmine shares are trading below intrinsic value, and the Company wants to be in a position to accretively retire common shares.
