Michael Saylor just fired off a public challenge to MSCI, calling on the index giant to scrap its proposed rule change that would boot Bitcoin-holding companies from major stock indexes. The controversy stems from MSCI's plan to exclude firms with substantial BTC treasury positions—a move that could hit MicroStrategy and other corporate Bitcoin adopters hard. Saylor's pushback highlights a brewing clash: traditional finance gatekeepers versus companies betting their balance sheets on crypto. If MSCI pushes through, it might force a reckoning for businesses treating Bitcoin as a strategic reserve asset. The stakes? Index exclusion typically means reduced institutional investment flows and potential stock valuation pressure. Watch this space—it's shaping up as a test case for how legacy finance infrastructure handles the corporate crypto wave.
