Microsoft's $270 Billion OpenAI Windfall Hinges on a Trillion-Dollar IPO
Published on 07/05/2026 at 13:13 | Redaktion boerse-global.de
The software giant finds itself in a peculiar spot: its cloud business is firing on all cylinders, yet its stock is the worst performer among big tech this year, down more than 15%. June was the bleakest month since the dot-com collapse, with shares plunging 18–19% and touching a low of €307.10 on the 25th. A modest recovery has lifted the stock to €342.00 — up 0.25% on the day and 4.30% for the week — but it still languishes 10.35% below its 200-day moving average of €381.48. The annualized volatility has spiked above 40%, underscoring the market's jittery mood.
The main event that could alter this trajectory is brewing outside Redmond. OpenAI, the creator of ChatGPT and Microsoft's premier artificial-intelligence partner, has filed a confidential draft registration with the SEC. Chief executive Sam Altman is reportedly targeting an initial public offering as early as 2027 at a valuation north of $1 trillion. Microsoft currently owns roughly 27% of the start-up, a stake valued at around $135 billion based on prior private transactions. Should the IPO hit that trillion-dollar mark, the holding would be worth approximately $270 billion — nearly 9% of Microsoft's entire market capitalisation. Adding to the strategic heft, OpenAI is contractually committed to spending $250 billion on Azure cloud services over the long term.
The stock's technical picture remains brittle. The 100-day moving average sits at €344.00, and a sustained breakout above that level would help erase memory of the June rout. The relative strength index reads 51.5, leaving room for movement in either direction. One overhang removed recently: the Bill & Melinda Gates Foundation unloaded its remaining 7.7 million shares, a package worth about $3.2 billion, in a sale that had no visible impact on the share price.
Should investors sell immediately? Or is it worth buying Microsoft?
Meanwhile, Microsoft is doubling down on its own AI push. The newly formed "Microsoft Frontier Co." comes with a $2.5 billion budget and more than 6,000 employees tasked with delivering custom enterprise solutions. Adoption of Microsoft 365 Copilot is spreading through thousands of organisations, with notable wins such as a five-year partnership with consumer-health giant Haleon and a plan by NHS England to roll out Copilot to 500,000 staff. All this comes at a heavy cost: capital expenditure for fiscal 2026 is budgeted at roughly $190 billion, a 61% increase from the prior year. Jefferies analysts have cautioned that the broad AI investment cycle could wobble if returns fail to materialise soon.
Azure's momentum, however, gives the bull case some heft. Revenue grew nearly 40% in the most recent quarter, and fresh surveys of US IT chiefs show that 55% now consider Azure their primary cloud provider, versus 29% for AWS. The analyst consensus remains a "Moderate Buy," with the average price target hovering around €518. All eyes will turn to the fourth-quarter earnings release on 28 July, where the market expects revenue of $82.9 billion and earnings per share of $4.27.
For now, the OpenAI IPO narrative is the dominant theme, promising a windfall that could transform Microsoft's balance sheet. But until those gains are real and the capital-spending drag starts to ease, the gap between operational strength and stock-market sentiment is likely to persist.
