Microsoft vs. Broadcom: Two AI Powerhouses, One Better Investment
Azure crossed $100B annually and Copilot reached 30 million paid seats, while Broadcom's AI chip revenue surged 143%.
Microsoft's $678 billion contracted backlog and diversified software base make it the steadier compounder; Broadcom's 18% pullback offers higher AI torque with more concentration risk.

Microsoft (NASDAQ: MSFT) and Broadcom (NASDAQ: AVGO) sit on opposite sides of the same AI trade.
Microsoft just closed Q4 FY2026 with $90.01 billion in revenue, while Broadcom posted Q2 FY2026 revenue of $22.187 billion. One rents the AI factory. The other sells the picks. Comparing them right now tells you where enterprise spending is actually landing.
Microsoft's quarter was a software story wearing an infrastructure suit. Intelligent Cloud jumped 32% to $39.31 billion, Azure grew 43% year over year, and full-year Azure revenue crossed $100 billion for the first time. Microsoft 365 Copilot hit over 30 million paid seats, and commercial RPO of $678 billion, up 84%, is the number I keep circling. That is contracted work, not hope.
CEO Satya Nadella framed it plainly: "We are advancing the frontier on the cost-to-outcome curve, ensuring every customer can turn tokens into business results." Reported non-GAAP EPS came in at $4.74, topping the $4.2397 consensus estimate.
Broadcom's quarter was pure silicon leverage. AI semiconductor revenue reached $10.80 billion, up 143% year over year, and Hock Tan guided Q3 AI semis to $16 billion, growth over 200%. Operating income more than doubled to $10.788 billion, up 85.07%. EPS of $2.44 topped the $2.3972 estimate, extending an eight-quarter beat streak.
The strategic split is architectural. Microsoft is spending like a utility: full-year CapEx of $115.95 billion pushed free cash flow down to $19.639 billion, a 23.19% decline. That is the price of owning the AI stack from data center to Copilot license.
Broadcom took the opposite route. Fabless, asset-light, and shipping to a short list of hyperscalers, it turned $22.187 billion in revenue into $10.262 billion in free cash flow.
The 69% adjusted EBITDA margin is what happens when you sell scarce silicon to buyers who cannot switch quickly. The catch: customer concentration is real, and insider activity shows 62 recent transactions with net selling direction.
For Broadcom, the $29.4 billion Q3 revenue guide is the ballgame. Miss the $16 billion AI number and the P/E of 65 gets ugly fast. Shares are already down 18.02% since the June 3 earnings report.
For Microsoft, I am watching Copilot attach rates and whether that $678 billion RPO converts on schedule. Post-earnings, shares ran 24.87% higher through August 3, and Reddit's wallstreetbets crowd hit a very bullish 94 sentiment score on July 31. That level of sentiment typically cools.
On the current data, Microsoft looks like the steadier name. The 27 P/E, the $678 billion backlog, and the diversification across enterprise software make it the steadier compounder. Copilot monetization is real, and Azure at $100 billion annualized gives Nadella pricing power that Broadcom cannot replicate.
That said, if you want maximum AI torque and can stomach the volatility, Broadcom is the cleaner semiconductor bet. A 143% growth engine trading below its $527.88 analyst target after an 18% pullback is interesting. It carries more concentration risk. Hock Tan's $100 billion AI sales goal by 2027 is aggressive, and hyperscaler order patterns can turn quickly. Both work. Microsoft just sleeps better.
