Bitmine’s $257M Annualized Staking Income Helps Fund Buybacks, Analysts Say

Bitmine Immersion Technologies, currently the largest corporate holder of Ether, says its staked ETH has crossed the 5 million mark—an upgrade that could translate into significant recurring income. In a Monday announcement, the company reported that its ETH holdings reached 5.81 million tokens, with more than 5 million of them staked, estimating roughly $257 million in annualized revenue from staking.

The development adds to a wider shift among crypto companies that are exploring Ether as a treasury asset that can generate “native yield,” even as markets remain sensitive to ETH price swings and staking economics.

Key takeaways

• Bitmine says it has staked over 5 million ETH, estimating about $257 million in annualized staking revenue.
• According to Bitfinex exchange analysts cited by Cointelegraph, staking was the dominant source of Bitmine’s revenue in the quarter ended May 31.
• Staking income is not guaranteed: it depends on staking yield, ETH price assumptions, and operational and regulatory factors.
• Ether treasury firms face pressure when ETH’s spot price falls, with SharpLink reporting a large Q2 net loss tied to unrealized crypto losses.
• Despite risks, staking can provide a recurring “buffer” that may help smooth treasury planning and reduce reliance on selling ETH.

Bitmine’s 5 million staked-ETH milestone

Bitmine’s Monday update frames staking as a measurable cash-flow engine for corporate balance sheets. The company stated that its ETH holdings reached 5.81 million tokens, with staked tokens surpassing 5 million. The announcement also pointed to an estimated $257 million in annualized revenue tied to staking.

Analysts from Bitfinex, quoted by Cointelegraph, described staking as the foundation of Bitmine’s earnings. For the fiscal quarter ending May 31, they said Ether staking accounted for about 98% of the company’s revenue—$45.7 million out of $46.5 million.

“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 distinction matters for treasury strategy. When a company can fund buybacks and operating costs without liquidating its crypto exposure, it reduces the need to sell during potentially unfavorable market conditions.

Why staking is attracting treasury managers

Ether’s role as a treasury asset is increasingly discussed as a complement to traditional capital management. Alvin Kan, chief operating officer at Bitget Wallet, told Cointelegraph that Bitmine’s milestone illustrates how ETH can produce native yield at the treasury level.

Kan contrasted this with the more common framing of Bitcoin (BTC) in corporate treasuries. In many cases, BTC is treated primarily as a balance-sheet appreciation asset. Ether staking, by comparison, can create recurring inflows, which can change how companies think about risk and returns.

At the same time, Kan emphasized that staking revenue is not simply “fixed income.”

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

In other words, Ether staking behaves less like a guaranteed coupon and more like a yield-bearing overlay on a larger treasury position. The key uncertainty is whether the assumed yield holds up over time—while operational and regulatory complexities can affect execution, and liquidity needs can influence whether staked ETH remains locked for periods that may not align with corporate cash-flow requirements.

ETH price weakness tests corporate staking strategies

The case for staking looks stronger when ETH yields are stable and liquid capital is not required. But the economics can worsen when ETH spot prices decline, because treasury value and reported results can diverge sharply from staking inflows.

Cointelegraph notes that Ether treasury companies are facing growing unrealized losses as margins come under pressure. It cited that ETH’s spot price fell about 23% during the second quarter of 2026, a backdrop that can magnify mark-to-market losses even if staking continues.

SharpLink, described as the second-largest Ether treasury company, reported a net loss of $394 million for the second quarter of 2026. Cointelegraph linked the loss largely to $391 million in unrealized crypto losses, highlighting the asymmetry investors often face: staking can add cash yield, but declines in asset prices can still overwhelm reported profitability depending on accounting and measurement.

In terms of scale, Bitmine was cited as holding 5.54 million ETH (valued at about $9.4 billion at the time of reporting), while SharpLink held 863,000 ETH (about $1.46 billion), according to data compiled by StrategicEthReserve.

This comparison underscores a practical tension in the category: staking revenue may provide operational funding and some smoothing effect, but it does not remove exposure to ETH price volatility—especially when balance sheets are measured on prevailing market prices.

Current staking yield and what investors should watch

Ether staking can be evaluated in two layers: the on-chain yield and the market value of the underlying ETH. Cointelegraph reported that ETH staking currently pays an annual percentage rate (APR) of 2.61%. It also cited Validatorqueue data indicating that over 34% of the total Ether supply is staked across 897,064 validators.

Those figures help explain why corporate staking can become a meaningful line item for large holders. But they also point to the variables that could change over time. If total staked supply rises faster than network rewards adjust, yields can compress. If validator performance or operational constraints occur, effective yields can differ from headline APR.

Meanwhile, the market can continue to test treasury strategies via ETH spot movements. In that context, recurring staking income may act as a “buffer” to fluctuations, as argued by a Seeking Alpha contributor in a July 28 report that Cointelegraph referenced. The core idea is that recurring staking revenue can support planning even when spot valuation is under pressure—but investors should interpret that as financial resilience rather than immunity from downside.

For readers tracking Ether treasuries, the next signals to watch are whether staking revenues translate into sustained operating cash flow across market cycles, how companies manage liquidity given validator and regulatory constraints, and whether APR/yield conditions remain favorable as more corporate holders consider staking as a strategic component of their balance sheets.
