Fidelity More Than Doubles Strategy Stake to 1.02 Million Shares

Fidelity more than doubled its stake in Strategy Inc. (NASDAQ: MSTR) during the third quarter of 2026, according to an SEC filing submitted November 10. FMR LLC, the parent of Fidelity Investments, reported 1,022,050 Class A common shares — a 132% increase from the 439,718 shares held at the end of Q2.

The disclosure comes from FMR LLC's Q3 2026 13F filing, the periodic report institutional managers must file with the SEC. The numbers show conviction at scale. The stake's market value climbed from roughly $38.2 million at the end of Q2 to about $156.5 million by September 30.

Common stock is only part of the picture. Fidelity's holdings also include Strategy convertible bonds and Series A perpetual preferred shares.

Who else bought in?

Fidelity wasn't alone in adding exposure during the quarter.

• Amundi raised its Strategy holdings by roughly 44% to about 1.9 million shares, a position valued near $291.4 million.
• Fulcrum Asset Management opened a brand-new position, disclosing 54,876 shares worth about $8.5 million.

None of the filings explain the reasoning. A 13F lists what a manager owns. It does not include a memo about why.

Why does Strategy attract this attention?

Strategy occupies an unusual spot in public markets. It's a software company that also functions as a Bitcoin treasury vehicle, steadily accumulating the cryptocurrency and raising capital through a range of financial instruments to fund those purchases.

The company's Q3 2026 earnings put that model on display. Strategy reported net income of roughly $19.53 billion for the quarter, driven heavily by unrealized gains on its Bitcoin holdings.

Unrealized is the operative word. Those gains exist on paper because Bitcoin's value moved, not because Strategy sold anything, and the same accounting that produced a large profit in a rising market can work in reverse when prices fall.

What does this change for investors?

There are caveats worth keeping in mind. 13F data is backward-looking: these positions reflect holdings as of September 30, and the filing landed on November 10. Six weeks is a long time in Bitcoin markets.

Large asset managers also run many funds with different mandates. A position disclosed at the parent level can reflect a mix of decisions across various products, so a single filing isn't necessarily one portfolio manager's conviction call.

Still, Fidelity's spread across the capital stack — common shares, convertible bonds, Series A perpetual preferreds — suggests a layered approach to Strategy exposure. Each instrument carries a different risk and return profile depending on which layer is in play.

For Strategy itself, steady institutional demand matters beyond any share-price move. The company depends on raising capital through stock, debt, and preferred offerings to keep buying Bitcoin. Buyers for those instruments are the fuel for the engine, and the latest filings show several large players willing to supply it.

The next test arrives with Q4 2026 13F filings, due by mid-February 2027, which will show whether institutions held, added, or trimmed these positions through the quarter's Bitcoin price swings.
