Key Insights
- Vanguard’s large strategy stock stake comes from passive index tracking, not active Bitcoin buying.
- Strategy Inc.’s valuation and stock volatility are primarily driven by its substantial Bitcoin holdings.
- Institutional investors reduced their MSTR exposure in Q3 2025, highlighting shifting risk appetite.
Vanguard Group continues to hold a major stake in Strategy Inc. (NASDAQ: MSTR). However, the stock faces sharp swings tied to Bitcoin’s price. A post on X claimed Vanguard was “buying Bitcoin,” but the reality is more routine.

Vanguard’s position comes from passive index tracking, not active crypto investing. Still, the size of its stake and the volatility of MSTR have drawn attention. The company remains the world’s largest corporate holder of Bitcoin, and its strategy continues to shape market reactions.
Viral Claims and Vanguard’s Actual Position
A post on X from the account @Vivek4real_ made a bold claim about Vanguard’s stake in MicroStrategy. It said Vanguard now owns $3.2 billion worth of MSTR. It also suggests that Vanguard is buying Bitcoin.
The number in the post is close to estimates based on Vanguard’s most recent Q3 2025 13F filing. As of September 30, 2025, Vanguard reported owning about 19.88 million shares of Strategy Inc. At current prices, that stake is valued at roughly $3.33 billion.
However, Vanguard’s holdings are passive. They come from MSTR’s inclusion in broad‑market indices that Vanguard funds track. Vanguard has repeatedly described digital assets as speculative. It has also stated that it has no plans to launch its own cryptocurrency products.
During Q3 2025, institutional investors reduced their marked‑to‑market exposure to MSTR by about $5.38 billion. Total institutional holdings fell from $36.32 billion to $30.94 billion.
Strategy Inc.’s Bitcoin Accumulation and Stock Volatility
Strategy Inc., led by Executive Chairman Michael Saylor, continues to expand its holdings of Bitcoins. As of December 14, 2025, the company held 671,268 Bitcoin. The total cost of these purchases is about $50.33 billion.
The average price paid is $74,972 per coin. This includes a recent purchase of 10,645 Bitcoin between December 8 and 14, valued at $980.3 million.
MSTR stock has been highly volatile in 2025. The swings are closely tied to Bitcoin’s price because of the company’s leveraged treasury strategy. On December 17, 2025, shares traded around $167.50. Earlier in the year, the stock traded above $450.

Charts of MSTR’s 2025 performance show sharp rises and steep declines. The movements reflect the company’s dependence on Bitcoin and the market’s reaction to its ongoing accumulation strategy.
Institutional Ownership and the Passive Investing Debate
Updated institutional ownership data for Q4 2025 will be released in mid‑February 2026. Passive index funds, such as those from iShares and Vanguard, adjust their positions based on fund flows and index changes. They do not make active decisions about Bitcoin exposure.
In early December 2025, Vanguard updated its brokerage policies to allow trading of third‑party cryptocurrency ETFs, including spot Bitcoin funds. This change does not signal a shift in its cautious stance on crypto.
Strategy Inc.’s software business continues, but its valuation is driven mainly by its Bitcoin holdings. These holdings are funded through debt and equity issuances. Institutional ownership remains around 55–60 percent. Major holders include Vanguard, BlackRock, and State Street.
The situation highlights how passive investing can inadvertently expose millions of index fund investors to cryptocurrencies. The link between traditional finance and digital assets is continuing to grow, often in ways that investors do not expect.
