Bitmine’s $300M Preferred Stock Plan Sparks Fresh Bets on Ethereum Treasury Expansion

Bitmine Immersion Technologies has unveiled plans for a $300 million Series A Perpetual Preferred Stock offering, proposing 3 million shares priced at $100 each. While framed as a capital raise, the move is fueling speculation that the firm is preparing to deepen its Ethereum exposure.

Shares of Bitmine (BMNR) climbed roughly 5.8% following the announcement, even as Ethereum slipped 1.7% over the past 24 hours to around $1,650, extending its weekly decline.

At the center of investor focus is how Bitmine intends to deploy the proceeds—whether toward general corporate purposes or a continued buildout of one of the largest ETH treasury positions in the market.

Offering Structure Points to Long-Term Strategy

The preferred stock carries a 9.5% cumulative dividend, paid weekly when declared, with a step-up mechanism that can push the rate as high as 15% if payments are deferred. The shares are expected to trade under the ticker BMNP on the New York Stock Exchange.

Bitmine has outlined multiple potential uses for the capital, including Ethereum and digital asset purchases, expansion of staking operations, working capital, ecosystem investments, and share repurchases. However, the absence of a clearly defined allocation leaves room for interpretation.

The company’s previous capital raise in September 2025 was largely directed toward ETH accumulation, reinforcing the view that this latest move could follow a similar path.

As of early 2026, Bitmine holds approximately 4.14 million ETH and 192 BTC, alongside substantial cash reserves, positioning it among the largest institutional holders of Ethereum. A portion of its ETH is actively staked, generating yield through validator operations.

Ethereum Strategy Echoes MicroStrategy—With a Twist

Bitmine’s approach draws comparisons to Strategy’s Bitcoin-focused playbook, which leverages capital markets to expand digital asset holdings. However, Bitmine’s Ethereum-centric model introduces a key distinction: yield.

Through staking, Bitmine can potentially generate ongoing income from its ETH reserves—an advantage that could help offset its dividend obligations. This contrasts with Strategy’s reliance on asset sales to meet similar commitments.

Still, questions remain over whether staking returns alone can sustain a near double-digit dividend on a $300 million issuance, particularly in volatile market conditions.

For now, the market appears to be betting that Bitmine’s latest raise is less about routine financing—and more about doubling down on Ethereum.
