MicroStrategy Executive Chairman Michael Saylor has reiterated his confidence that the company will join the S&P 500 index, potentially by mid-2026, despite facing rejections in 2025. Saylor, in a CNBC interview, pointed to the firm's Bitcoin-centric business model as a key eligibility factor. The company has met the index's technical requirements, including a market cap exceeding $22.7 billion and recent profitability, for over 115 days. Analysts project that inclusion could trigger up to $30 billion in inflows from passive funds, significantly boosting Bitcoin's mainstream legitimacy.
However, MicroStrategy's relentless Bitcoin accumulation strategy is showing signs of strain. On January 26, 2026, the company disclosed its latest purchase of 2,932 BTC for approximately $264.1 million at an average price of $90,061 per Bitcoin. This brings its total holdings to 712,647 BTC, acquired at an average cost of $76,037 per token for a total investment of roughly $54.19 billion. Crucially, this purchase was funded entirely by issuing new shares—1,569,770 common shares ($257.0M) and 70,201 preferred shares ($7.0M)—rather than from operational profits.
A critical metric, the multiple to net asset value (mNAV), has slipped into discount territory at approximately 0.94x, meaning MicroStrategy's stock trades at a 6% discount to the Bitcoin backing each share. This undermines the core of its strategy, which relies on issuing shares at a premium to NAV to accretively increase Bitcoin holdings per share. Data shows Bitcoin per diluted share increased only 0.38% in January, with recent issuance barely moving the needle, indicating the model is losing efficiency.
The company faced S&P 500 rejections in September and November 2025, with the committee reportedly citing concerns over crypto volatility and sector balance. Critics, including economist Peter Schiff, have questioned the sustainability of a strategy so dependent on Bitcoin's price and continuous capital market access. Over the past 19 months, MicroStrategy has raised an estimated $18.56 billion through equity issuance, with accelerating dilution now threatening to erode, rather than create, shareholder value if the mNAV discount persists.
