Analysts: Bitmine’s $257M annualized ETH staking income funds gaps, buybacks

Bitmine Immersion Technologies, described by its latest disclosures as the largest corporate holder of staked Ether, has pushed its staking balance beyond the 5 million ETH mark. In an announcement released Monday, the company reported holdings of 5.81 million staked Ether, projecting roughly $257 million in annualized revenue from staking-related income.

The update arrives as Ether treasury firms are increasingly using staking to generate recurring cash flows—while still confronting the risk that reduced spot prices can erode margins and mark-to-market results. Recent figures underscore the tension: Cointelegraph reported that Ether staking accounted for about 98% of Bitmine’s revenue for the fiscal quarter ending May 31.

Key takeaways

• Bitmine says it has 5.81 million staked ETH, estimating $257 million in annualized staking revenue.
• According to Bitfinex analysts cited by Cointelegraph, staking drove ~98% of Bitmine revenue in the quarter ending May 31.
• Ether’s staking income is often treated as steadier than spot price exposure, but it depends on ETH price, staking yield, and operational constraints.
• Ether treasury companies face mounting paper losses when ETH spot falls; SharpLink reported $391 million in unrealized crypto losses in Q2 2026.
• As of current staking-network data, Ether staking shows an APR of 2.61%, with 34%+ of supply staked across 897,064 validators.

Bitmine’s staking jump and what it funds

Bitmine’s Monday announcement is framed around a milestone: it has moved past 5 million ETH in staked tokens. The company tied the scale of its staking position to an estimated $257 million in annualized revenue.

Cointelegraph also cited analysis from Bitfinex exchange showing how concentrated Bitmine’s income has become. For the fiscal quarter ending May 31, staking generated $45.7 million out of $46.5 million in total revenue—about 98%.

“It funds operations and its share buyback program: 19.1 million shares repurchased since July against a $4 billion authorisation, without Bitmine having to sell any Ether.”

That last detail matters for how investors may evaluate treasury strategies. If a company can finance buybacks and operating needs without liquidating volatile crypto holdings, it may reduce the need to sell during unfavorable price regimes—at least in principle.

Why Ether is finding a treasury role—and the limits of staking income

Bitmine’s milestone has reinforced a broader trend: Ether staking is increasingly discussed as a way for corporate balance sheets to earn native yield. Cointelegraph quoted Alvin Kan, chief operating officer at Bitget Wallet, arguing that Ether can function as a yield-bearing treasury asset, while Bitcoin is more commonly framed as an asset held for balance-sheet appreciation.

However, Kan stressed that staking revenue is not risk-free. Ether’s yield can vary and treasury operators must manage multiple layers of exposure beyond “headline APR.”

“The revenue is annualized, depends on ETH price and staking yield, and comes with operational, liquidity, validator and regulatory considerations.”

This distinction is important for market participants comparing corporate crypto strategies. Staking can smooth some income—but it does not eliminate the need for disciplined treasury planning. The income model should be viewed as an enhancement to broader capital management rather than a simple replacement for traditional risk controls.

Even where recurring staking income is valued as a “buffer,” the underlying economics remain sensitive to ETH market conditions. Cointelegraph cited an opinion piece from July 28 on Seeking Alpha by Yiannis Zourmpanos, which argued that annualized staking receipts can be modeled with less direct dependence on spot ETH prices. Still, the approach depends on assumptions about yield persistence and the operational ability to sustain staking over time.

Falling ETH spot prices amplify unrealized losses

While staking can generate recurring income, treasury firms are not insulated from valuation impacts when Ether trades lower. The source notes that Ether’s spot price fell roughly 23% during the second quarter of 2026, a move that pressures margins and increases unrealized losses for entities holding large crypto reserves.

SharpLink, identified as the second-largest Ether treasury company, illustrates the problem. Cointelegraph reported that SharpLink posted a $394 million net loss for Q2 2026, driven largely by $391 million in unrealized crypto losses.

That contrast with Bitmine’s staking-heavy revenue highlights a key asymmetry. A company can generate staking proceeds without selling—yet its financial statements may still reflect spot-driven mark-to-market declines on the underlying holdings. For investors, the practical question becomes whether staking income is sufficient to offset these valuation moves on a reported basis, and how much of the exposure is unrealized versus realized.

How much Ether is staked—and who leads among corporate holders

The staking activity behind Bitmine’s model is supported by broader network participation. According to data from Validatorqueue, Ether staking currently offers an APR of 2.61%. The same dashboard shows that over 34% of the total Ether supply is staked across 897,064 validators.

In corporate terms, the data cited in the source points to a clear leader-follower dynamic. Cointelegraph stated that Bitmine is currently the largest corporate Ether holder at 5.54 million ETH (worth about $9.4 billion at the referenced valuation), while SharpLink ranks second with 863,000 ETH (about $1.46 billion), according to information from the StrategicEthReserve data site.

Taken together, the figures suggest why staking is drawing attention from corporate treasuries: it can be scaled, monitored, and used to generate ongoing returns. But the same scale also magnifies reporting effects when ETH’s market price drops, increasing the importance of underwriting assumptions around yield durability and liquidity management.

Next, investors should watch whether corporate staking earnings remain stable as network conditions and ETH yield dynamics shift, and whether reported losses from spot declines continue to overwhelm staking proceeds—or eventually stabilize as prices and staking economics realign.
