Ethereum News Today: SharpLink's ETH Staking Strategy Redefines Corporate Treasury Management

SharpLink Gaming, Inc. (Nasdaq: SBET) reported a significant staking yield of 575 ETH for the week ending September 23, 2025, marking a total cumulative staking reward of 3,815 ETH since launching its Ethereum (ETH) treasury strategy on June 2, 2025 . This update underscores the company's aggressive ETH accumulation and strategic focus on maximizing returns through staking protocols. As of September 23, SharpLink's total ETH holdings reached 838,728 ETH, valued at approximately $3.51 billion, with all reserves fully allocated to staking . The company's ETH concentration metric, a proprietary measure of exposure relative to diluted shares, climbed to 3.97 as of September 14, reflecting a near-doubling since June .

SharpLink's treasury strategy has been bolstered by capital raised through its At-the-Market (ATM) facility. During the week of September 18–24, 2025, the company raised $46.6 million in net proceeds, enabling the acquisition of 39,008 ETH at an average price of $4,531 . Over the preceding months, SharpLink has consistently expanded its holdings through ATM sales, with total ETH purchases reaching 39,008 ETH for the week ending August 31, 2025, and 56,533 ETH for the week ending August 24, 2025 . The company's total staking rewards have grown from 2,318 ETH as of August 31 to 3,815 ETH by September 23, highlighting the compounding effect of its strategy .

The company's commitment to ETH staking is further evidenced by its recent $1.5 billion stock buyback program, approved by the board on August 18, 2025 . This initiative aims to enhance shareholder value while aligning with the company's long-term vision of leveraging digital assets for growth. SharpLink's ETH Concentration on a cash-converted basis exceeded 4.00 by September 23, a 100% increase from June levels . The company has also repurchased 1,938,450 shares since the buyback program's inception, with an average price of $16.67 per share .

SharpLink's strategy has drawn attention for its potential to redefine corporate treasury management. The company's ETH Concentration metric, calculated as total ETH held divided by 1,000 assumed diluted shares, has become a key performance indicator. This metric accounts for all issued shares, ATM sales, and convertible securities, excluding treasury adjustments . The rise in ETH concentration underscores SharpLink's shift toward a digital-first capital structure, with the company's net asset value (NAV) reaching $3.86 billion as of September 14, or $18.55 per diluted share .

Despite Ethereum's bearish price trend-down 7.5% week-to-date as of September 23-SharpLink continues to prioritize staking over liquidity. The company's unrealized gains from its ETH holdings totaled $496.86 million, with an average cost basis of $3,603 per ETH . CEO Joseph Chalom emphasized the alignment of SharpLink's strategy with Ethereum's long-term value proposition: "By expanding our ETH concentration, we reinforce our commitment to align the interests of SharpLink, Ethereum, and our shareholders while showcasing how digital assets can drive value creation" .

The company's approach has sparked broader industry discussions about the role of digital assets in corporate treasuries. Institutional investors, including Bitmine, have also increased ETH holdings, with the latter accumulating $69 million worth of ETH in a single week . Analysts note that SharpLink's model could inspire other firms to adopt similar strategies, particularly as regulatory clarity and institutional adoption of crypto continue to evolve .
