Bitmine is set to conclude its aggressive Ethereum acquisition strategy in late 2026, as it approaches its maximum treasury limit of 5% of the total ETH supply. Speaking at the Token2049 conference in Singapore, Bitmine Chairman Tom Lee confirmed that the firm requires roughly 100,000 more ETH to reach this ceiling. At current acquisition rates, this final accumulation phase is projected to last between six and seven weeks, bringing an end to one of the most significant institutional buying streaks in crypto history.
The multi-month accumulation has solidified Bitmine’s position as a dominant force in the institutional crypto space, providing a consistent source of buy-side liquidity. By reaching this 5% threshold, the firm will effectively cease the sustained purchasing pressure that has served as a primary price floor for Ethereum throughout the 2026 fiscal year. Lee’s transparency regarding the timeline provides a clear exit window for momentum traders who have been following Bitmine’s wallet activity.
From a regulatory standpoint, Bitmine’s decision to cap its holdings at 5% likely serves as a strategic move to avoid reaching the "dominant stakeholder" status that often triggers intensive oversight from the U.S. Securities and Exchange Commission (SEC) and the CFTC. By staying at the 5% mark, Bitmine avoids specific disclosure requirements and potential antitrust scrutiny that could arise from controlling an even larger portion of a decentralized network's circulating supply.
Investors and market participants should now monitor how Ethereum’s price reacts to the removal of this institutional tailwind as Bitmine enters a "hold and stake" phase. While the end of the buying spree removes a major demand source, it also signals the completion of a massive, stable institutional floor. Watch for the official announcement of the cap completion in early November 2026, which may lead to a short-term volatility spike as the market recalibrates to a post-Bitmine-buying environment.
