Ethereum staking works, but the bill is real
- BMNR has moved from Bitcoin mining to an ETH treasury and staking model.
- Staking and validation produced $45.7M, or 98% of total revenue, in the quarter ended May 31, 2026.
- The Pier Two deal and MAVAN launch turn the story toward institutional staking services.
- A $273.8M Series A Preferred Stock raise adds capital, but also an estimated $33.25M annual dividend burden.
- Finn's low overall view fits the setup: fast revenue growth, weak financial health, and a hard valuation question.
Yield is real, so is the hurdle
The bull case got stronger this quarter. BMNR's staking revenue jumped to $45.7M in the quarter ended May 31, 2026, making up 98% of total revenue. That is no longer a small test. It shows that the ETH yield plan is now the main business.
The next step is MAVAN. After buying Pier Two for $27.8M, BMNR launched MAVAN and plans to offer staking services to third-party institutions. If customers sign up, BMNR could be seen less like a passive ETH holder and more like a blockchain infrastructure company.
The bear case is also sharper. After the quarter, BMNR raised $273.8M through Series A Preferred Stock. That brings in capital, but it also creates an estimated $33.25M annual dividend obligation. If ETH falls, or staking yields drop, that bill could eat much of the cash the business makes.
The stock therefore depends on three things: ETH price, staking yield, and proof that MAVAN can win customers. Until those are clearer, the low Finn scores on financial health and valuation make sense.
A treasury that must earn
BMNR buys and holds ETH as its main treasury asset. It has funded that strategy mainly by selling stock, including through an ATM program. That can work when investors value the company above its net asset value, but it can also dilute shareholders if new shares are sold often.
The company then stakes ETH. Staking means locking ETH into the Ethereum network to help validate transactions and earn rewards. Those rewards are now the main revenue source.
BMNR also uses options on digital assets, makes strategic venture investments in Ethereum-related companies, and runs a small consulting or advisory business. These may add upside, but they also make the story harder to track.
The old Bitcoin mining and miner leasing lines are effectively over. BMNR is now tied to ETH price, staking yields, execution at MAVAN, and the cost of running a large digital asset treasury.
What BMNR actually sells
ETH Treasury and Staking Operations
This is the core business. BMNR holds ETH and stakes it to earn rewards.
MAVAN Institutional Staking
MAVAN is the new commercial push after the Pier Two acquisition. The goal is to serve institutional investors, custodians, and Ethereum ecosystem partners.
Treasury-Related Derivatives
BMNR uses digital asset options to seek income and manage its treasury. This can help returns, but it can also create losses outside the staking business.
Strategic Venture Investments
The company makes moonshot investments in Ethereum ecosystem companies. These positions could pay off, but they may be illiquid and hard to value.
Digital Asset Ecosystem Services
This is a small consulting and advisory line. It is capital-light, but it is not the main driver today.
Legacy BTC Operations
The old Bitcoin mining operation has been wound down. It still appeared as a small legacy revenue line in the latest quarter.
Almost all staking now
For the three months ended May 31, 2026, BMNR reported $46.5M of total revenue. Staking and validation was $45.7M, so the revenue mix is highly concentrated in one activity.
What can break the story
ETH price and staking yield drop together
High impact · Medium oddsBMNR earns rewards in a market where both token price and yield can move fast. If ETH falls while network staking yields compress, revenue and asset value can weaken at the same time. That would make the preferred dividend and operating costs harder to cover.
Preferred dividend cash drag
High impact · High oddsThe Series A Preferred Stock adds an estimated $33.25M annual dividend obligation. That is a fixed hurdle for a company whose cash generation depends on variable staking rewards. If yields are not enough, BMNR may need to use cash reserves or sell assets.
MAVAN fails to win trust
High impact · Medium oddsMAVAN is moving from internal infrastructure to a service for third-party institutions. That puts BMNR against established staking providers. A slow sales cycle, weak pricing, or one operational failure could hurt the business case.
Slashing or custody failure
High impact · Low oddsIn proof-of-stake networks, validators can lose funds through slashing if they break network rules or run poorly. For BMNR, a slashing event could damage its own ETH holdings and its reputation with future MAVAN clients. The risk grows if third-party assets are added.
Dilution fatigue
Medium impact · High oddsBMNR's treasury growth has relied on selling stock to buy more ETH. That can be accretive when the stock trades above net asset value. If the premium fades, the model can slow or become painful for common shareholders.
Complex side bets
Medium impact · Medium oddsOptions and venture investments add return paths outside core staking. They also add fair value swings, illiquidity, and possible losses that a simple ETH treasury would not have. This makes reported results harder for retail investors to read.
In one breath
Is BMNR still a Bitcoin mining company?
Not in any meaningful way. The company has wound down legacy Bitcoin mining and leasing, while ETH staking is now the main revenue driver.
How does BMNR make money from Ethereum?
BMNR holds ETH and stakes it on the Ethereum network. Staking earns rewards for helping validate transactions, and those rewards made up most of the latest quarter's revenue.
What is MAVAN?
MAVAN is BMNR's staking infrastructure platform after the Pier Two acquisition. The company wants to move it from an internal tool to a service for institutional clients.
What is the biggest risk for BMNR shareholders?
The main risk is that staking income may not keep up with costs, especially the estimated $33.25M annual preferred dividend. A lower ETH price or lower staking yield would make that harder.
