MSCI finalized a rule on Oct. 15 that classifies "non-operating companies" as ineligible for its Global Investable Market Indexes, a change that could remove Michael Saylor's Strategy from the widely tracked benchmarks effective Nov. 30.

The index provider will apply the rule as part of its November index review. It implements a proposal MSCI floated in August with minor modifications. The methodology screens for corporate issuers that lack substantial operating assets and behave more like passive investment vehicles than operating businesses.

Companies that fail an initial "core screen" then run through an exclusion test built on five financial ratios. A stock gets flagged as ineligible if it trips four or more of those ratios.

Who does the rule target?

The change aims squarely at firms whose balance sheets are dominated by a single asset — the model Saylor's Strategy pioneered with its holdings of hundreds of thousands of Bitcoin, and which Japan's Metaplanet and a wave of imitators adopted. Strategy trades at a premium to the value of its crypto holdings, a premium that index removal could compress.

MSCI built in buffers to limit index churn:

• Current constituents face removal only if they fail the screen in each of their two most recent annual filing periods.
• New additions are blocked if they fail in either of the last two periods.

MSCI will publish the final list of affected companies on Nov. 11.

What happens to the 2025 reprieve?

The decision also ends a temporary measure. As the crypto-treasury trend expanded, MSCI last year froze certain index adjustments for companies whose digital-asset holdings made up 50% or more of total assets. That interim reprieve is now scrapped, and all such firms will be assessed under the new rules.

Removal from major MSCI indexes would force index-tracking funds to sell the affected shares. That selling would pressure stock prices and shrink the premium these companies have long commanded over the value of their crypto. Saylor had urged MSCI to drop what he called a "discriminatory" rule that would delete Strategy from its benchmarks.

How are treasury companies responding?

The threat has already prompted defensive maneuvers. Metaplanet recently sold 10,000 Bitcoin and bought back 11,000 to demonstrate active treasury management. Strategy has kept accumulating, adding to its stack even as the index question loomed.

The stakes center on passive demand: index-tracking funds that buy constituents mechanically provide a stable shareholder base, and losing that channel would leave treasury firms more dependent on discretionary investors. The Nov. 11 list and the Nov. 30 effective date now define the near-term calendar for Strategy, Metaplanet and the broader cohort of single-asset balance sheet companies.
