Sharplink Earns Millions in Ethereum Staking Rewards — But Faces Massive Unrealized Losses

TL;DR:

• SharpLink earned $28.1M in staking rewards (14,516 $ETH) after staking almost 100% of its treasury, but shows ~$1.39B unrealized losses.
• Bitmine reports 4.47M $ETH (3.71% supply) and stakes 68% for ~$172M annual revenue; SharpLink holds ~864,840 $ETH and targets a $3,588 cost basis.
• $ETH hovered near $1,981 as ETFs saw $10.8M outflows; SharpLink sold 10,975 $ETH ($33.54M) OTC in Nov 2025, signaling flexibility amid weaker crypto-linked stocks.

SharpLink is drawing attention with a staking-heavy Ethereum treasury that is generating real yield while bleeding on paper. The firm reported about $28.1 million in staking rewards, equal to 14,516 $ETH, after staking almost 100% of its $ETH holdings. Yet CoinGecko data shows roughly $1.39 billion in unrealized losses as ether slid below $2,000. That contradiction is the story: staking revenue is rising even as mark-to-market losses deepen, forcing investors to separate operating momentum from price exposure. SharpLink controls about 0.717% of total $ETH supply and compounds daily at current prices.

Staking Yield Meets Balance-Sheet Drawdown

CoinGlass-style scoreboard comparisons are sharpening the narrative, and Bitmine Immersion Technologies is the clearest benchmark. Bitmine said its treasury reached 4.47 million $ETH, about 3.71% of circulating supply, nearly four times SharpLink’s roughly 864,840 $ETH. The firms are not running the same playbook. Bitmine is pursuing scale and market influence, and it stakes about 68% of its stash, roughly 3 million $ETH, for an estimated $172 million in annual staking revenue. SharpLink is different: it is staking nearly everything to grind down a $3,588 average cost basis. That makes yield a balance-sheet lever, not optional.

The broader tape is not confirming the treasury enthusiasm. SharpLink’s stock (SBET) fell 1.76% to $7.26 and Bitmine’s (BMNR) dropped 4.16% to $19.57, while ether traded around $1,981, down 0.73% over 24 hours. ETF flows also flashed caution, with Ethereum ETFs recording $10.8 million in outflows on March 3. Put together, public-market buyers are hesitating near $2,000 even as corporate treasuries keep accumulating. That divergence matters for governance teams because funding costs, liquidity, and sentiment can decouple quickly. If $ETH stays range-bound, staking income can soften drawdowns, but it cannot offset prolonged price weakness indefinitely.

SharpLink’s own chain history adds nuance. Onchain Lens reported that in November 2025 the company sold 10,975 $ETH worth about $33.54 million via an OTC transaction with Galaxy Digital. That sale suggests the staking narrative is not a one-way lockup when pressure rises from losses and a high purchase price. Management is effectively running a treasury flywheel: stake to earn, and adjust exposure when needed. The report’s conclusion is blunt: the strategy works only if $ETH recovers enough to outpace the loss overhang. Until then, rewards buy time, not certainty, and keep stakeholders aligned internally.
