BitMine’s Stake-Heavy Quarter and the Agreement That Makes an Exit Tricky

Staking ate the revenue pie

Short version: BitMine’s business is basically staking and validation — and a lot of it. In the quarter ending May 31, 2026, the company pulled in $46.535 million in total revenue, of which $45.743 million (about 98.3%) came from staking and validation. That means MAVAN, BitMine’s Ethereum validator network, was producing almost every dollar reported for the period.

At quarter-end BitMine reported holding 5,416,945 ETH, valued around $10.856 billion. A later update showed roughly 4,718,677 ETH staked out of about 5.4169 million on hand — so roughly 87% of the stash was actively earning staking rewards. Ambitions to grab a larger slice of Ethereum’s supply remain a future plan rather than a finished scoreboard entry.

That concentration cuts both ways: if staking yields slide, validators suffer downtime, slashing happens, or the protocol changes, BitMine’s top-line would feel it immediately. In plain speak — when staking sneezes, BitMine catches a cold.

The management deal that won’t just shrug and go away

Here’s where the plot thickens. BitMine controls 98% of MAVAN Holdings, while a company called Ethereum Tower holds the other 2% as a noncontrolling interest. Under a management services agreement effective March 24, Tower handles delegated strategy and day-to-day staking, validator infrastructure, and tech work. BitMine’s BMNR unit remains the formal manager on paper and keeps certain reserved powers.

Importantly, Tower’s 2% stake is irreversible unless it’s sold or assigned, and Tower also receives a monthly slice of revenue from BitMine’s native staking — the exact split is redacted, so we can’t eyeball the exit bill in dollars. That agreement runs for an initial 10-year term, but BMNR can walk away with 180 days’ notice if it wants to terminate for convenience.

If BMNR pulls the plug early for reasons not tied to Tower’s misconduct or similar faults, Tower gets to choose one of two outcomes: keep collecting its revenue participation for the rest of the term even after it stops managing day-to-day operations, or take a lump sum equal to 85% of its highest monthly fee in the prior 12 months (or the shorter elapsed period) multiplied by the remaining months. Because the allocation numbers are redacted, nobody outside the closet can do the math on the exit price.

Even a replacement of the operator doesn’t make the obligations vanish. Tower has to stop providing services and cooperate with a new operator, but its 2% economic interest and the continuing revenue-or-lump-sum choices can still stick around. The upshot: BitMine’s ETH game is not only tied to staking performance, but also to a third-party management setup that can outlive an early split.

Bottom line: BitMine is riding a staking-powered rocket ship, but the booster pack comes with contractual velcro — profitable while it flies, potentially awkward if they try to land early.
