2 Artificial Intelligence (AI) Stocks to Buy Before They Soar to $5 Trillion in 2026, According to Wall Street

Morgan Stanley’s Brian Nowak and Wells Fargo’s Michael Turrin forecast that Alphabet and Microsoft could each reach roughly $5 trillion market capitalizations (Alphabet $415/share, ~35% upside; Microsoft $700/share, ~47% upside) on sustained AI-driven growth. The bull case for Alphabet centers on monetizing generative-AI innovations (AI Overviews/AI Mode), Gemini’s 650 million monthly users, Google Cloud share gains and a strong Q3 (revenue +16% to $102B; GAAP EPS +35% to $2.87). Microsoft’s case rests on rapid adoption of its Copilot suite (150M MAUs), plans to roughly double Azure data‑center capacity in two years, and robust Q3 results (revenue +18% to $78B; adjusted EPS +23% to $4.13). Analysts say these AI and cloud dynamics could justify current 30–32x earnings multiples if execution and revenue acceleration continue, but the outcome hinges on sustained monetization and scale.

Analysis

Morgan Stanley’s Brian Nowak and Wells Fargo’s Michael Turrin present bull-case targets implying Alphabet at $415 per share (~35% upside from $307) and Microsoft at $700 (~47% upside from $475), each equating to roughly $5 trillion in market value. Those targets rest explicitly on sustained AI-driven monetization and continuing cloud share gains.

Alphabet reported Q3 revenue up 16% to $102 billion and GAAP EPS up 35% to $2.87, with Gemini reaching 650 million monthly users and Google Cloud gaining ~1 percentage point of infrastructure market share year-to-date; Wall Street models forecast ~8% annual EPS growth through 2026. The company has clear options to monetize Gemini (no ads yet) and recent beats (average 14% above consensus over six quarters) support a bullish narrative, but the current ~30x earnings multiple assumes continued outperformance.

Microsoft posted Q3 revenue +18% to $78 billion and non-GAAP EPS +23% to $4.13, with copilot MAUs rising to 150 million and Azure adding ~1 percentage point of share while planning to "roughly double" data-center footprint in two years. Street estimates see ~16% adjusted EPS CAGR to fiscal 2027 and Microsoft’s ~32x multiple looks more tolerable given steady execution, but realization of the $5 trillion scenario depends on successful enterprise monetization and timely capacity build-out; key risks are slower ad integration for Gemini and execution on cloud expansion.

Key Decisions for Investors

• Consider overweighting Microsoft versus Alphabet on execution grounds given stronger near-term revenue and EPS growth (Q3: revenue +18%, adj. EPS +23%) and an explicit Azure capacity expansion plan, while monitoring progress on the data-center build and enterprise monetization
• Adopt a selective hold or accumulate-on-weakness stance for Alphabet because Q3 growth (revenue +16%, GAAP EPS +35%) and Gemini scale (650M MAUs) support upside, but demand confirmation of ad monetization and continued Google Cloud share gains before adding material exposure
• Use event-driven hedges or option structures ahead of key milestones (Gemini ad integration updates, Google Cloud/Azure share and capacity disclosures, and quarterly beats) to protect positions since the $5 trillion scenarios hinge on successful AI monetization and execution
