SharpLink vs. Bitmine: A Closer Look at Two ETH Treasury Stocks as Prices Slide
Author: Zhou, ChainCatcher
As ETH weakens this cycle, the two largest publicly traded Ethereum "treasury" companies have both moved deep into the red, each sitting on losses greater than 50% on their core holdings.
SharpLink has returned to buying after an eight-month pause. It recently added 39,196 ETH at an average cost of about $3,609, leaving it with more than $1.7 billion in unrealized losses at current prices. Bitmine has kept expanding aggressively, with ETH holdings now at 5.7 million ETH—roughly 4.7% of circulating supply—and unrealized losses topping $10 billion.
Both stocks are included in the Russell indexes and both helped fund the newly formed Ethereum research institute, Ethlabs. Yet despite similar entry costs and similar share-price drawdowns, the market is applying very different valuation discounts: SharpLink trades at about a 21% discount to its ETH net asset value (NAV), while Bitmine trades at roughly a 6% discount.
For investors looking for equity-based ETH exposure in a potential bottoming phase, the key question is less about storytelling and more about measurable drivers—cost basis, financing capacity, liquidity, and whether headline narratives can translate into durable value.
Institutional polish vs. visible scale
SharpLink leans heavily on an institutional-facing narrative. Its Ethereum ties are prominent, with Joe Lubin serving as chairman and former BlackRock digital assets executive Joseph Chalom as co-CEO. The company has also pushed into RWA tokenization partnerships and has discussed tokenizing SharpLink's own equity on Ethereum.
Bitmine's pitch is simpler: scale and visibility. It holds 5.7 million ETH, and chairman Tom Lee has far higher public and media presence than most peers. Bitmine is also in the more selective Russell 1000. Management argues that index inclusion can attract hundreds to thousands of institutional holders, noting that passive vehicles often end up owning 18% to 20% of a public company's float.
Both narratives sound investable. The market's discount gap suggests investors care more about execution mechanics than marketing.
Cost basis and share-price damage: similar percentages, different magnitudes
The most direct comparison is who acquired ETH at a better price.
SharpLink disclosed on June 30 that it bought 10,000 ETH at an average price of about $1,611, bringing total holdings to 886,725 ETH. That total includes 632,719 native ETH, 181,299 ETH redeemable from lsETH, and 72,707 ETH redeemable from weETH. SharpLink's average cost basis is about $3,609 per ETH. With ETH around $1,650, the unrealized loss is roughly $1.74 billion, down about 54.3%.
Bitmine, as of June 28, 2026, reported total Ethereum holdings of 5,700,040 ETH—about 4.7% of Ethereum's total supply. On-chain data puts its average cost basis near $3,400 per ETH. Unrealized losses are around $11 billion, down roughly 51.5%.
The percentage declines are close. The difference is size: Bitmine's ETH position is about 6.4 times larger, so the dollar loss is more than six times bigger.
On the equity side, both charts tell a familiar treasury-stock story: an early spike after listing, a long slide, then low-level consolidation. As of the July 1 close, SharpLink had fallen from a $124 peak to around $5 (down about 96%). Bitmine dropped from a $160 peak to about $14 (down about 91%). Market caps are roughly $1.02 billion for SharpLink and about $7.6 billion for Bitmine.
Financing speed and liquidity: where the gap widens
SharpLink's financing has largely been incremental and dilutive, relying heavily on ATM issuance to slowly raise capital and add ETH over time. The latest restart in buying is tied mainly to a $75 million private placement completed last month, which issued 10,013,400 common shares plus the same number of warrants. The company said proceeds would go to working capital, continued ETH accumulation, and share repurchases.
SharpLink is also trying to enhance returns through staking. Since launching its ETH treasury strategy, it has earned 22,102 ETH in staking rewards.
Bitmine's fundraising has been far more aggressive. A 10x Research report estimates the company raised $19.2 billion via 50 equity offerings from July 2025 through May 2026, using the proceeds to buy roughly 5.54 million ETH.
Last month, Bitmine also began adopting a playbook associated with the largest Bitcoin treasury company, rolling out preferred stock financing. Its Class A perpetual preferred shares, BMNP, have been approved for listing on the New York Stock Exchange. The board approved a cash dividend of $0.1056 per share, payable July 10 to shareholders of record as of June 30.
Russell index inclusion helps both companies on the margin by improving access to capital and trading activity. SharpLink is in the Russell 3000, while Bitmine is in the Russell 1000. Tom Lee has argued that many active managers restrict purchases to Russell 1000 constituents, and that passive index funds or ETFs often hold 20% to 25% of a stock's market cap. More passive ownership can translate into better liquidity and stronger support for continuous equity issuance—critical for any strategy that depends on repeated capital raises.
That financing advantage shows up in mNAV. DefiLlama data indicate SharpLink trades at about a 21% discount to ETH NAV, while Bitmine is discounted by about 6%. A deeper discount can trap a company in a negative loop: issuing more shares pushes the stock down further, which worsens the discount and makes future issuance even more punitive. SharpLink's eight-month pause in buying was largely tied to this dynamic.
Liquidity tells a similar story. Bitmine has long been among the more actively traded U.S. stocks, with daily turnover often in the hundreds of millions of dollars. SharpLink's daily volume is roughly an order of magnitude smaller. For investors trying to capture a discount-to-NAV trade, liquidity shapes entry and exit costs—spreads and slippage can erase theoretical value. Bitmine has a clear edge here.
The hidden price of convenience
Bitmine's liquidity and tighter discount are not free. According to 10x Research, Bitmine posted an overall loss of about $10.1 billion over the past year. That figure includes not only unrealized losses from ETH's decline but also a second component: investors previously paid a premium to mNAV to own BMNR shares, totaling roughly $4.6 billion in premium paid.
In practice, Bitmine shareholders can face an extra layer of downside versus holding ETH directly: the asset can fall, and the stock can also compress from a premium to a discount. SharpLink, which has largely traded at a discount, is less exposed to that specific "premium unwind" risk.
RWA tokenization and ecosystem narratives: promising, not yet monetized
On tokenized equity, SharpLink has been explicit. In September 2025 it announced plans to tokenize SBET shares with Superstate through the Opening Bell platform, positioning itself as the first public company to issue shares natively on Ethereum. In an interview this October, co-CEO Joseph Chalom said the company aims to launch a compliant tokenized version soon and favors Ethereum over Solana for the underlying infrastructure.
So far, the initiative remains an intention rather than a live on-chain business, with no observed on-chain transactions or revenue contribution. SharpLink and Superstate have said additional regulatory approvals are needed, particularly around how tokenized stocks could trade on decentralized exchanges.
Bitmine has taken a different tack, pitching "moonshot" equity allocations as a way to diversify beyond a single-asset ETH bet. Management has referenced indirect exposure to OpenAI and an equity investment in Beast Industries. These positions do not provide stable cash flow today, but they add speculative optionality.
Both companies also backed Ethlabs, the new Ethereum research institute. The timing is notable: the Ethereum Foundation reportedly cut about 40% of its 2026 budget and eliminated 54 roles, and former core development coordinator Trent Van Epps has warned core development could face a funding gap within three to nine months.
On governance and funding risk, SharpLink's Joseph Chalom said Ethlabs will complement the Ethereum Foundation, while acknowledging overlap and adding that the "most concentrated talent" will be at Ethlabs. Bitmine's Tom Lee has dismissed crisis concerns, saying funding is already secured.
For now, RWA tokenization and Ethlabs function more as long-horizon sector narratives than as proven revenue engines. Neither company has clearly turned them into near-term earnings power.
How to think about the choice
If the goal is tactical exposure during a potential bottoming phase, Bitmine is the easier vehicle. It trades closer to NAV and offers materially better liquidity, lowering trading friction and making entry and exit costs more predictable.
For longer-term holders, Bitmine's drawbacks are clearer. The perpetual preferred layer introduces a fixed cash cost that has already begun, and prior premium periods leave the stock more exposed to valuation compression. SharpLink's capital structure is simpler, and its share price already reflects more pessimism, meaning new buyers are less likely to be paying for yesterday's premium.
Scenario-wise:
If ETH keeps falling, both companies' unrealized losses will rise. With a much larger position, Bitmine's dollar losses will expand faster, and its current valuation advantage could narrow, putting its financing flywheel under sharper stress.
If ETH stabilizes and rebounds, SharpLink's lower starting valuation implies more room for discount narrowing. Bitmine may need to work through residual valuation froth from earlier premium periods before the equity fully participates.
Ultimately, the two stocks represent different distributions of the same core risk. SharpLink's vulnerability is visible in price and liquidity. Bitmine's vulnerability sits inside its capital structure and the legacy of prior premium pricing. The better choice depends on which risk matters more to the investor.
