Copilot Crosses 20 Million Seats as Microsoft Wins Pentagon and Wall Street Confidence

Microsoft’s artificial intelligence push is gaining traction on multiple fronts, with the company’s Copilot product hitting a key adoption milestone, a fresh $9.7 billion Pentagon deal, and a high-profile endorsement from billionaire investor Bill Ackman. The Redmond-based tech giant’s stock has responded, though some of the optimism may still be working its way into the price.

Ackman Places a $2 Billion Bet on Microsoft’s Valuation

Pershing Square USA, the hedge fund run by Bill Ackman, has built a core position in Microsoft, disclosing a holding of 5,654,078 shares. Ackman said the stake was accumulated at roughly 21 times expected earnings — a multiple close to the broad market and well below Microsoft’s historical average. The move signals institutional conviction that the company’s AI-driven growth story is undervalued relative to its potential.

The disclosure comes as analysts remain broadly bullish. Piper Sandler’s Billy Fitzsimmons reiterated an “Overweight” rating with a $540 price target after meetings with Microsoft’s investor relations chief. He noted that upcoming Copilot features — including Model Choice, Copilot Cowork, and WorkIQ — could drive further seat additions in the fiscal fourth quarter. Of the analysts tracked, 34 rate the stock a buy, two a hold, and none a sell. The 12-month consensus price target sits at $559.98, with the most optimistic forecast at $680 and the floor at $400.

Pentagon and EY Deals Validate Cloud and AI Strategy

Microsoft has locked in a five-year contract with the U.S. Department of Defense valued at $9.7 billion for software license consolidation. The deal, which will also be executed through a Dell-managed contract estimated at $9.69 billion, gives military personnel access to Microsoft’s cloud services, AI tools, and enterprise software. On the commercial side, the company struck a multi-billion-dollar AI partnership with accounting giant EY, aimed at accelerating enterprise adoption of Microsoft’s AI platform.

Should investors sell immediately? Or is it worth buying Microsoft?

These agreements underscore growing institutional demand for Microsoft’s cloud and AI capabilities. The company’s internal IT organization, Microsoft Digital, has already demonstrated the efficiency gains: it slashed hybrid-cloud onboarding from several months to one day using AI-powered automation and reusable building blocks.

Copilot Surges Past 20 Million Seats — But Penetration Remains Low

The most tangible sign of product momentum is Microsoft 365 Copilot. The company redesigned its flagship AI assistant to be faster and more intuitive, and the market has responded. In the fiscal third quarter ended March 2026, paid Copilot seats surpassed 20 million, up from 15 million in the prior quarter. New seat additions surged 250% year-over-year, the fastest growth since launch, and the number of customers with more than 50,000 seats quadrupled.

Still, 20 million seats represent only about 4.4% of the total Microsoft 365 installed base, leaving substantial room for expansion. Piper Sandler’s Fitzsimmons noted that more enterprises are adding Copilot mid-contract, and usage intensity is developing in line with expectations.

Q3 Earnings Beat and Azure Acceleration on the Horizon

The commercial momentum is backed by solid financials. Microsoft reported fiscal third-quarter earnings per share of $4.27, topping the consensus estimate of $4.05. Revenue reached $82.9 billion, ahead of the $81.29 billion forecast, and grew 18.3% year-over-year. Microsoft 365 Commercial Cloud revenue rose 19% (15% in constant currency), driven by E5 subscriptions and Copilot uptake.

For the current quarter, the company guided for Azure growth of roughly 39.5% in constant currency, above the 36.9% analyst consensus. Management expects new capacity coming online in the second half of calendar 2026 to allow a slight acceleration. Demand for computing capacity continues to outstrip supply, and Microsoft remains committed to heavy AI investment, betting that long-term cloud revenue growth will exceed capital spending.

Stock Action and Technicals

After a strong Friday session that saw shares jump 3.68% to €379.95, the stock eased to trade at €371.60, up 1.41% on the day. Year-to-date, the stock is still down 7.93%, and it sits 5.36% above its 200-day moving average. The 52-week high of €467.45 is 18.7% away, while the 50-day line at €345.56 provides a support floor. The relative strength index of 41 suggests the market has yet to fully price in the recent positive developments.

With Copilot adoption still in its early stages, a major Pentagon contract locked in, and a marquee hedge fund investor on board, Microsoft’s AI narrative is gaining substance beyond mere expectations. The fiscal fourth quarter will be the next test — if Copilot seats keep climbing and Azure hits its growth target, the stock’s current discount to its historical valuation could narrow.
