MSFT vs ZM: How Microsoft and Zoom Communications Compare (2026)

Same yardstick, side by side (as of July 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

Reading it: ZM is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. MSFT and ZM share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined MSFT and ZM exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

Microsoft (MSFT) is one of the largest and most diversified technology companies in the world, operating across three reporting segments. Productivity and Business Processes includes Microsoft 365 (Office, Teams, Dynamics 365) and LinkedIn. Intelligent Cloud covers Azure, GitHub, server products, and enterprise services. More Personal Computing spans Windows, gaming (Xbox plus the acquired Activision Blizzard), Surface devices, and search via Bing. Azure is the second-largest cloud computing platform in the world behind AWS, and Microsoft 365 is the dominant productivity suite for businesses globally. AI is woven across all of it through the Copilot product line and a deep partnership with OpenAI, in which Microsoft is both the primary cloud provider and a major investor. The company was founded in 1975 by Bill Gates and Paul Allen, is headquartered in Redmond, Washington, and is led by CEO Satya Nadella (since 2014). Microsoft is consistently the largest or one of the two largest publicly traded US companies by market cap, with enormous recurring cash flow and a multi-decade dividend-growth streak.

Zoom Communications is a cloud communications company best known for its video-conferencing platform, which became a household name during the pandemic. Its core product lets people host video meetings, webinars, and calls reliably across devices, and the business sells subscriptions to individuals, small businesses, and large enterprises. Since the pandemic boom faded, Zoom has worked to evolve from a single video-meeting product into a broader unified-communications and workplace platform: Zoom Phone (cloud telephony), Zoom Contact Center, Team Chat, Zoom Rooms for hybrid offices, Zoom Docs and Whiteboard, and an expanding suite of AI features branded Zoom AI Companion. Most revenue still comes from meeting subscriptions, but management is pushing the higher-growth phone, contact-center, and AI products to re-accelerate growth and deepen enterprise relationships. Founded in 2011 and headquartered in San Jose, California, Zoom holds a large net cash position and competes against Microsoft Teams, Google, and Cisco in a crowded communications market.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• MSFT drivers: AI as the platform; Closing the gap with AWS in cloud.
• ZM drivers: Platform expansion beyond meetings; AI Companion and monetization.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: The largest open question is the return on AI capex: Microsoft is spending more than $50 billion a year on AI and cloud infrastructure, and if enterprise adoption is slower than expected the payback stretches out. For ZM, zoom's central challenge is growth: after the pandemic surge, revenue growth slowed to low single digits as the core meetings market matured and online (small-business) churn rose.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick MSFT if you believe its drivers more; ZM if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the MSFT and ZM guides.

MSFT. For comparison, the S&P 500 trades at roughly 22x earnings on average. Microsoft's premium reflects its combination of growth, durability, margins, and AI exposure through Azure and OpenAI. It is not the highest P/E in mega-cap tech; NVIDIA, for example, trades at roughly 50x. The premium is justified as long as Azure keeps growing double digits and the AI capex earns a return; multiple compression risk rises if cloud growth slows. All figures are approximate as of early 2026 and refresh quarterly; verify against Microsoft's investor relations page or your broker.

ZM. Zoom trades at a modest multiple for a profitable software company, reflecting slow top-line growth and competitive pressure from Microsoft despite high margins, strong free cash flow, and a large net cash pile. A meaningful share of the market cap is cash. Investors weigh the cheap valuation and buybacks against the risk that growth stays muted and meetings commoditize.

Headline figures (approximate, early 2026): MSFT shows revenue (fy2025 ending june) ~$245 billion, growing ~15% year over year, operating margin ~45%, among the highest of any company at Microsoft's scale, net income ~$95 billion, eps (ttm) ~$12.80; ZM shows revenue (ttm) ~$4.7 billion, revenue growth low single digits, non-gaap operating margin ~38-40%, free cash flow ~$1.5 billion annually.

MSFT and ZM are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
