Which Big 3 Cloud Computing Stock Is the Best Buy Now?

AWS accounted for 59% of Amazon's operating profits in the latest quarter, while AWS revenue rose 28% year over year; Microsoft Azure grew 40% and Google Cloud grew 63%. The article argues AI demand is boosting cloud spending and recurring inference revenue, with Amazon viewed as the best buy because cloud tailwinds flow most directly to its bottom line. Alphabet's TPU sales are also accelerating cloud growth, but the piece remains constructive on all three hyperscalers.

Analysis

The key tradeable point is not “cloud is good,” but that the market is starting to re-rate cloud from a growth annuity into an AI utility layer with much stickier monetization than classic enterprise software. That favors vendors with the highest operating leverage to incremental utilization, and it explains why the profit mix matters more than revenue growth alone: a business that already converts cloud demand into bottom-line dollars will compound faster as AI workloads become more inference-heavy over the next 12-24 months.

The second-order winner is upstream silicon and networking, but only selectively. If custom accelerators keep taking share, the value chain shifts toward whoever controls architecture, interconnect, and power efficiency; that compresses some of the economics of generic GPU rental while expanding margins for proprietary stack owners. The risk is that headline cloud growth stays strong while unit economics normalize, which would make the “fastest growing” platform less important than the one with the best margin capture.

Consensus is probably underestimating how much of this is already priced in for the hyperscalers, especially the one whose cloud is now the profit engine rather than a call option. The more interesting contrarian angle is that the market may be over-rewarding revenue acceleration and underweighting capex intensity, depreciation drag, and competitive pricing pressure as AI capacity comes online. Over the next 6-18 months, a pause in AI spend or evidence of slower inference growth would hit the high-multiple cloud names first, even if demand remains structurally positive.

Key Decisions for Investors

• Stay long AMZN as the highest-quality cloud cash-flow compounder, but size it as a 6-12 month hold rather than a tactical momentum trade; reward is further multiple support if cloud margins expand, while the main risk is capex intensity compressing near-term FCF.
• Pair trade: long AMZN / short MSFT for the next 1-2 quarters if the market keeps bidding pure cloud profit conversion over diversified software exposure; thesis is better incremental earnings sensitivity in AMZN with lower downside from cloud underperformance.
• Initiate a relative-value long GOOGL vs short an AI-infrastructure basket if TPU adoption continues to take share; this captures proprietary silicon monetization while hedging against broader cloud multiple compression.
• Avoid chasing NVDA here on this specific narrative unless there is confirmation that custom accelerators are not displacing merchant GPUs as fast as feared; otherwise the stock faces a 3-6 month digestion period from mix-shift concerns.
• Use any post-earnings pullback in AMZN or GOOGL to add, but only if cloud growth remains above 25% and management commentary supports sustained AI demand; below that threshold, the risk/reward shifts from buy-the-dip to wait-for-reset.
