Q2 2026 earnings season settled one of the biggest debates on Wall Street: the hyperscalers are converting their AI infrastructure spending into accelerating cloud revenue, not just capex line items. Every one of the big three cloud platforms posted growth reacceleration in the quarter that just wrapped, and each stock reacted differently, creating three distinct entry setups for August.
The setup for the second half is simple. AI-related capex among the top hyperscalers is now running at roughly $452 billion in 2026, more than four times what the entire US publicly traded energy sector spends. That money is showing up as backlog, revenue and margin at Microsoft, Amazon and Alphabet. Here are the three cloud names to keep an eye on this month.
Microsoft (MSFT)
Microsoft (NASDAQ:MSFT | MSFT Price Prediction) trades at $464.72 with a P/E of 26, a forward EPS estimate of $19.96, and a Wall Street target of $563.05 against 54 buy-or-better ratings and zero sells.
The Q4 fiscal 2026 report on July 29 is the reason to pay attention now. Revenue landed at $90.01 billion, up 17.75%, non-GAAP EPS came in at $4.74 versus a $4.24 estimate, and Azure grew 43% year over year, capping a full year in which Azure crossed $100 billion in revenue for the first time. Commercial remaining performance obligations swelled to $678 billion, up 84%, and Microsoft 365 Copilot passed 30 million paid seats. CEO Satya Nadella framed it plainly: "Azure revenue surpassed $100 billion for the first time, and Microsoft 365 Copilot reached over 30 million paid seats, reflecting the confidence customers are placing in us to power their AI transformation."
The bull case: an accelerating cloud franchise with visible multi-year backlog and five straight EPS beats. The caveat: full-year capex hit $115.95 billion, up 79.62%, and free cash flow slipped 6.46% for the year. If Azure growth ever stalls, the capex intensity becomes a problem fast. For now, the shares are still down 3.48% year to date despite a 21.75% pop last week, keeping this a coiled setup entering August.
Amazon (AMZN)
Amazon (NASDAQ:AMZN) is the reacceleration story. Shares are at $271.58, up 17.66% YTD, and the stock ripped 15.32% on July 31 alone after earnings.
Q2 revenue was $200.61 billion, up 19.6%, with operating income climbing 43% to $27.46 billion. AWS hit $42.23 billion at 37% growth, the fastest pace in 18 quarters, with a 39.4% operating margin. Custom silicon and AI services each cleared $25 billion in annualized run rate growing at triple-digit rates. CEO Andy Jassy summed it up: "AWS is booming, growing 36.7% year-over-year in Q2, our fastest growth in 18 quarters, and our AI and Chips businesses each eclipsed run rates of more than $25 billion."
Q3 guidance calls for $197 billion to $202 billion in sales and $22.5 billion to $26.5 billion in operating income. The forward P/E based price sits at $486.01, well above the $321.95 analyst target, and Polymarket traders are pricing a 98.4% probability that 2026 capex tops $170 billion.
The caveat is the same infrastructure bill: Q2 capex of $54.21 billion pushed TTM free cash flow negative at -$7.6 billion, and management flagged tariff and recession risk in guidance. The bet here is that AWS growth continues compounding faster than the capex bill.
Alphabet (GOOGL)
Alphabet (NASDAQ:GOOGL) is the cheapest large-cap cloud/AI name on the board. Shares trade at $356.13 against a P/E of 18, cheaper than either Microsoft or Amazon, and the stock is up 86.11% over the past year.
The July 22 Q2 report was the standout of the quarter. Revenue reached $119.80 billion, up 24.2%, and Google Cloud accelerated to $24.77 billion at 82% growth, with nearly 90% of the Fortune 100 using Gemini Enterprise. Operating margin expanded 2 percentage points to 34%. CEO Sundar Pichai told investors, "Q2 was an amazing quarter, with Alphabet revenues growing 24% year-over-year and Google Cloud revenues accelerating to 82% growth, driven by demand for AI infrastructure and AI solutions." Gemini models now process 22 billion API tokens per minute, and the Gemini App has 950 million monthly active users. Polymarket traders assign an 88.5% probability that the next Gemini Pro model releases by August 31, a near-term catalyst worth watching.
Q2 capex doubled to $44.92 billion, free cash flow flipped to -$5.86 billion, long-term debt jumped from $46.5 billion to $98.2 billion, and the buyback was suspended. Investors are being asked to underwrite one of the largest infrastructure builds in corporate history. At 18x earnings, with cloud growth accelerating to 82%, the risk-reward remains the most attractive of the three.
