Ethereum Accumulation Surge: BitMine and SharpLink Expand ETH Holdings in Q3 2025 & November Recently, both Ethereum treasury companies BitMine and SharpLink actively accumulated ETH during Q3 2025 and November. BitMine (BMNR) saw its ETH holdings surge from about 163,000 in July to nearly 3.4 million by early November, exceeding 3.5 million the following week - a 20-fold increase. With a 15.6% increase over the past 30 days, it has become the leader in corporate ETH holdings. Despite market fluctuations causing unrealized losses, Chairman Tom Lee publicly expressed strong confidence in Ethereum, demonstrating a "buy the dip" strategy that reflects long-term bullish intent. SharpLink (SBET) similarly continued accumulating, reaching 861,250 ETH by November 9th. The company added over 43,000 ETH since late Q3, including 2.5% in the past 30 days, with approximately 19,000 ETH acquired in October alone. Their holdings are currently at an unrealized gain, supported by strong Q3 performance and significant net profit growth. Furthermore, the company plans to deploy portion of its ETH to Layer2 networks and generate additional returns through professional services, indicating a more proactive asset management strategy.
