MSCI Rules Approved That Could Remove Strategy, Metaplanet From Equity Indexes

The reclassification of investment-holding companies as index-ineligible creates a structural question for equity funds that currently include Bitcoin treasury firms as equity positions.

MSCI has approved new index eligibility rules that would exclude companies whose primary activity is holding investments, a change that could remove Bitcoin treasury firms Strategy and Metaplanet from major equity indexes, according to CoinDesk, reporting on October 16, 2026.

The rules were first proposed by MSCI in August 2026. Under the approved framework, companies that exist mainly to hold investments rather than operate an underlying business would no longer be eligible for inclusion in MSCI equity indexes. MSCI has not yet published a specific effective date or transition timeline in the material available as of this report.

Strategy, the Virginia-based company formerly known as MicroStrategy, has built its corporate model around accumulating Bitcoin on its balance sheet. As of its most recent public disclosures, Strategy held more Bitcoin than any other publicly traded company. Its common shares trade on the Nasdaq under the ticker MSTR and are currently included in several MSCI indexes tracked by institutional funds globally.

Metaplanet is a Tokyo-listed firm that adopted a similar Bitcoin accumulation strategy beginning in 2024. It is Japan's largest publicly traded Bitcoin holder by disclosed holdings. Both companies derive a substantial portion of their market capitalization from the value of Bitcoin on their balance sheets rather than from operating cash flows.

The practical consequence of index removal would be forced selling by passive funds that track MSCI benchmarks. Index funds and exchange-traded funds that replicate MSCI indexes are required to hold constituents in proportion to their index weight. If either company is removed from an index, funds tracking that index would be obligated to sell those shares, a process governed by the fund's own index-replication mandate rather than by any investment judgment.

The scale of potential forced selling depends on how many MSCI-tracking assets under management currently hold positions in Strategy and Metaplanet. That figure is not specified in the source material available as of this report. What would reveal it is a review of 13-F filings from US-based institutional managers and equivalent disclosures from non-US fund managers who benchmark to MSCI indexes.

MSCI's existing eligibility criteria already exclude real estate investment trusts and certain closed-end funds from some indexes on the grounds that their primary activity is holding assets rather than operating a business. The new rules would extend a similar logic to companies structured around cryptocurrency holdings, according to the CoinDesk report.

Strategy's stock has historically traded at a premium to its net asset value in Bitcoin, a dynamic that analysts have attributed to demand from equity investors who want Bitcoin exposure through a regulated stock rather than through direct cryptocurrency ownership or a spot Bitcoin ETF. Index removal could narrow or eliminate that demand channel from passive funds, though the direction and magnitude of any price effect would depend on market conditions at the time of any rebalancing.

Metaplanet's situation differs from Strategy's in one important dimension relevant to US investors: it is listed on the Tokyo Stock Exchange, not a US exchange. Its inclusion in MSCI indexes makes it accessible to global equity funds, including US-domiciled funds benchmarked to MSCI All Country World or MSCI Asia Pacific indexes. US investors in those funds would be indirectly affected by any index rebalancing that removes Metaplanet.

MSCI has not disclosed the implementation schedule for the approved rules in the material reviewed for this report. The specific criteria for determining whether a company's primary activity qualifies as investment-holding under the new framework have also not been detailed in available public sources. MSCI's index methodology documents, when updated, would be the primary source for those definitions.

The MSCI decision comes as a separate but related development in crypto markets shows stress in Bitcoin-collateralized lending. CryptoSlate reported on October 16, 2026 that native Bitcoin collateral activity on the Aave protocol triggered a deficit in a wrapped Bitcoin lending pool, a development that underscores ongoing liquidity management questions in markets where Bitcoin serves as a financial asset rather than a transactional currency.

For US investors, the MSCI rule change is the more directly consequential development near term. Passive equity funds benchmarked to MSCI indexes represent trillions of dollars in assets under management globally. Any mandatory rebalancing driven by eligibility changes would affect those funds' shareholders, including US retirement accounts and institutional portfolios that use MSCI benchmarks as their equity allocation framework.
