MSCI has finalized a rule change that classifies "non-operating companies" as ineligible for its Global Investable Market Indexes, effective November 30. The decision, announced on October 15, targets firms whose balance sheets are dominated by single assets like Bitcoin, including Strategy and Metaplanet. Under the new methodology, issuers lacking substantial operating assets undergo a core screen followed by an exclusion test based on five financial ratios; stocks are flagged if they fail four or more of these metrics.

This move scraps a temporary reprieve granted in 2025 to companies with digital-asset holdings exceeding 50% of total assets. To mitigate index churn, MSCI introduced buffers: current constituents will only be removed if they fail the screen in each of their two most recent annual filing periods, while new additions are blocked if they fail in either of the last two. The final list of affected companies is scheduled for publication on November 11.

Removal from major indexes would force passive funds tracking these benchmarks to sell the affected shares, potentially pressuring stock prices and reducing the premium these companies trade at over their underlying crypto value. Michael Saylor, CEO of Strategy, criticized the rule as discriminatory. In response to the regulatory threat, Metaplanet recently sold 10,000 Bitcoin and bought back 11,000 to demonstrate active treasury management, while Strategy continues to accumulate Bitcoin.
