Microsoft's $678 Billion Backlog: The Contractual Foundation Behind a 29% Monthly Surge
Published on 08/08/2026 at 13:02 | Redaktion boerse-global.de
The debate over whether Microsoft's artificial intelligence spending spree amounts to speculation or strategy has been settled by a number that rarely makes headlines: $678 billion. That figure — the company's contracted backlog of "remaining performance obligations" — grew 84% year over year, and it reframes the entire investment thesis around the software giant. Rather than betting on a future that may or may not materialize, Microsoft's capital expenditure program increasingly looks like a response to demand that is already locked in.
The market has taken notice. After closing Friday at €432.35, the stock has climbed 7.26% over seven days and nearly 29% over the past month. That kind of move, coming after a summer of so-called "AI fatigue," suggests investors are re-rating the company on the strength of its order book rather than its promises.
A Quarter That Quietly Rewrote the Narrative
The catalyst arrived on July 29, when Microsoft reported fiscal fourth-quarter results that blew past expectations. Revenue hit $90.0 billion — an 18% increase year over year and comfortably ahead of the $87.7 billion consensus. Adjusted earnings per share rose 23% to $4.74, helped in part by a $3.2 billion gain from the company's stake in Anthropic, which contributed $0.27 to the per-share figure.
Azure grew 43%, and Microsoft 365 Copilot reached 30 million paying users — double the previous count. The strength was enough to prompt Citi analyst Tyler Radke to raise his price target from $570 to $600 on August 6, maintaining a buy rating with a nod to Azure's momentum and management's guidance of 45% growth for the coming quarter.
Should investors sell immediately? Or is it worth buying Microsoft?
Between July 29 and August 7, the shares gained roughly 15%. That rally drew in Bill Ackman, whose Pershing Square Capital Management took a fresh $2.1 billion position on August 6 — timing that suggests he bought into relative weakness rather than chasing euphoria.
The Cash Flow Contrast That Sets Microsoft Apart
What distinguishes Microsoft from its hyperscale rivals is not the size of its investment program but what happens around it. On August 7, it emerged that Microsoft was the only major US cloud provider to post positive free cash flow in the fiscal fourth quarter, with a cash balance of $19.6 billion. Alphabet and Amazon, by contrast, reported negative figures for the same period.
That resilience is all the more striking given the scale of spending. Fiscal 2026 capital expenditures totaled $116 billion, up 80% from the prior year. For calendar 2026, Microsoft has guided toward roughly $175 billion in investments, a figure that reflects a balance-sheet reclassification of data center lease agreements. The company is effectively burning through capital at a rate that would strain most peers — yet still generating cash.
India: A Strategic Beachhead
Part of that spending is flowing into one of the world's most dynamic markets. On August 6, Microsoft officially opened its fourth cloud region in India, located in Hyderabad. It represents the largest facility of its kind in the country and forms part of a long-term investment commitment of $20.5 billion for the region.
With over 1,000 megawatts of secured renewable energy and anchor clients including HDFC Bank and Bajaj Finance, Microsoft is locking down infrastructure in one of the fastest-growing economies on the planet. The move underscores a broader transformation: this is no longer a US software company expanding abroad, but a global infrastructure provider building for the AI era.
Counterweights: Insider Sales and a Legal Challenge
The bullish picture is not without its frictions. On August 5, two senior executives sold shares. Commercial chief Judson Althoff disposed of 10,000 shares at an average price of $487.89, trimming his direct holdings by 9.05% to 100,447 shares. Marketing chief Takeshi Numoto sold 4,810 shares worth approximately $2.39 million. Neither transaction is alarming in isolation, but together they suggest some profit-taking at elevated levels.
There is also a legal overhang. The Gross Law Firm and Rosen Law Firm have called for a class action alleging Microsoft made misleading statements about Copilot adoption rates and the circular nature of its AI investments involving OpenAI and Anthropic. August 11 marks the deadline for shareholders to apply as lead plaintiff — a date worth monitoring.

Technicals Point to a Pause, Not a Reversal
At current levels, the stock is technically stretched. The 14-day relative strength index stands at 76.5, firmly in overbought territory — which helps explain Friday's modest pullback of 0.30%. A consolidation phase would be unsurprising.
Yet the medium-term trend remains intact. The shares still sit 9.57% below their 52-week high of €478.10 set in October. With the fundamental momentum behind the company, a retest of that level looks like a question of when, not whether.
One near-term catalyst arrives on August 20, when the stock begins trading ex-dividend. The payout of $0.91 per share follows in September — a modest event that does little to alter the larger picture.
The market capitalization of €3,131 billion now rests on a foundation that is far more tangible than it was six months ago. A $678 billion contracted backlog, accelerating Azure growth, and free cash flow that survives a $175 billion investment cycle — that combination transforms an expensive growth story into something closer to a contractual certainty. The rally may pause, but the underlying argument has never been stronger.
