Hyperscaler shares have ripped higher over the past week. Microsoft (NASDAQ:MSFT | MSFT Price Prediction) is up 26.5% in the last five trading days, Amazon (NASDAQ:AMZN) has climbed 20.4% over the same stretch, and Alphabet (NASDAQ:GOOGL) has added 12.5%. Uncover Alpha’s Rihard Jarc argues on X that this is only the beginning, writing, “I have called for a violent shift in upside repricing for hyperscalers… The repricing is in the works, and it is violent.” For investors who watched the move from the sidelines, the question is simple: is the door still open, or did the trade already run away?
Valuation: The Case Still Stands
Start with the multiples. Alphabet trades at roughly 17 times earnings while growing revenue 24% year over year, with Google Cloud accelerating 82% and operating margin expanding to 35.6% from 20.7%. Microsoft carries a P/E near 26, supported by 17.75% revenue growth, 46.78% operating margins, and a $678 billion RPO backlog that grew 84% year over year. Amazon is the richest of the three at roughly 32 times earnings, but AWS is compounding at 37%, a pace not seen in 18 quarters, with a 39.4% operating margin. For companies this large, growing this fast, the multiples do not look stretched enough to kill the trade.
Forward Catalyst: Backlog and Buildout
The forward setup is unusually visible. Microsoft’s Azure crossed $100 billion in annual revenue, a major milestone, and Microsoft 365 Copilot passed 30 million paid seats. Not to be outdone, Alphabet’s Cloud backlog reached $514 billion, and CFO Anat Ashkenazi raised full-year capex guidance to $195 billion to $205 billion to keep up with demand.
Amazon’s AI and custom-chips businesses each eclipsed a $25 billion annualized run rate. UBS now projects Amazon could exceed $500 billion in net profits by 2030. Management’s Q3 2026 guidance calls for operating income of $22.5 billion to $26.5 billion, up from $17.4 billion a year earlier.
Risk and Entry: Where the Downside Lives
The real risk is capex outrunning cash flow. Alphabet’s free cash flow turned negative $5.9 billion in Q2, worrying investors. Long-term debt swelled from $46.5 billion to $98.2 billion, and the buyback was suspended. Amazon’s TTM free cash flow sits at negative $7.6 billion after $54.2 billion of quarterly capex. Microsoft’s FCF fell 23.19% for the year as capex more than doubled to $115.95 billion.
Polymarket traders are also flagging near-term caution, pricing a 90.5% probability of a down day for Amazon on August 4. Independent research corroborates the structural case, with MetLife and PineBridge writing that “datacenter equipment growth as essentially locked in for the next four to five years” at roughly 25% annually.
The Verdict
It is not too late. Alphabet is the clearest value at 17 times earnings with 82% cloud growth and Wall Street targeting $426.95. Microsoft offers the highest-quality compounder profile, with analysts and buyers absorbing the capex on the strength of that $678 billion backlog. Amazon carries the richest multiple, but the AWS reacceleration and Q3 operating-income guide leave room to grow into it. For long-term investors evaluating exposure, the setup across all three names looks constructive even after a single day’s move, with plenty of forward catalysts still on the calendar.
