Morgan Stanley Boosts Bitmine Holdings 26% Amid Crypto Downturn

Morgan Stanley increased its BMNR holdings to 12.1 million shares in the fourth quarter of 2025, representing a 26% increase from the previous period. The position was valued at $331 million at quarter’s end, according to SEC filings. ARK Investment Management, the second-largest holder, similarly expanded its exposure by 27% to 9.4 million shares worth $256 million during the same timeframe.

The investment increases occurred despite severe downward pressure on BMNR’s stock price. The company’s shares fell approximately 48% during the fourth quarter of 2025 alone, and declined roughly 60% over the preceding six months, trading near $19.90 in premarket action on Thursday, December 19, according to Google Finance data. Despite these losses, both major institutional investors chose to add to their positions during the period.

The accumulation by top-tier institutional investors signals confidence in Bitmine‘s long-term positioning as a leading Ethereum treasury company, even amid broader cryptocurrency market weakness. The timing suggests these firms may view current valuations as attractive entry points or believe the company’s fundamentals remain sound despite near-term price volatility.

The filings do not disclose the specific rationale behind Morgan Stanley and ARK Investment Management‘s investment decisions, nor do they indicate whether additional purchases are planned. The precise composition of Bitmine‘s Ethereum treasury and its impact on shareholder value assessments remain undisclosed in available public statements.

Investors will monitor Bitmine‘s next earnings report and subsequent SEC filings to assess whether institutional confidence translates into operational improvements or further price recovery. The cryptocurrency market’s broader trajectory will likely influence near-term stock performance, regardless of institutional positioning.
