Microsoft and OpenAI: when a "marriage of convenience" turns into a toxic relationship

Just yesterday, the Microsoft-OpenAI alliance seemed like the smartest investment in Silicon Valley history. Satya Nadella looked like a chess grandmaster who delivered checkmate with a single move against the sluggish Google, simply by writing a check for several billion dollars. In return, Microsoft gained exclusive access to the world's most powerful language models and transformed its boring office software into futuristic Copilots. But in the world of big technology, the honeymoon doesn't last long, and today the same analysts who sang praises for this deal are frantically recalculating the risks. What began as ideal symbiosis increasingly resembles a codependent relationship, where each party secretly looks for an exit in case of a painful divorce.

The problem is that Microsoft bet too much without securing full control. Having invested over 13 billion dollars in total, the corporation essentially transplanted all its key products onto the GPT engine. But events last fall, when Sam Altman left the OpenAI CEO post for a couple of days due to internal turmoil, exposed a frightening reality. It turned out that the well-being of a trillion-dollar corporation directly depends on the mood of the board of a non-profit organization that Microsoft doesn't even fully control. This is not a partnership of equals and not even a classic acquisition—it's a strategic vulnerability that can no longer be ignored by either shareholders or management.

Regulators on both sides of the ocean have also woken up and started asking uncomfortable questions. The U.S. Federal Trade Commission and the antitrust authorities of Europe and Britain are carefully examining whether this partnership is a "hidden merger." Officials are concerned that Microsoft is using its Azure cloud power as a lever to limit competition in the AI market. If regulators decide that Microsoft has too much influence over OpenAI, the deal could be forcibly restricted or even terminated. For investors, this is a nightmare scenario: losing the exclusivity of technologies already paid for with billions, and being left with a pile of software that no one is updating.

OpenAI itself has no plans to remain permanently in the shadow of its "cloud godfather." Sam Altman is actively negotiating the attraction of colossal investments—we're talking about trillions of dollars—to create its own infrastructure for chip production and data centers. His goal is clear: reduce dependence on Azure capacity and become a completely autonomous player.

When your main partner starts building his own factory for what he used to buy from you, it's a telltale sign that loyalty has an expiration date. Microsoft understands this and has already begun a "quiet evacuation," hiring almost the entire core of the Inflection AI startup together with Mustafa Suleiman. This looks like taking out an insurance policy in case OpenAI completely goes its own way.

Now we are witnessing a classic stage of cooling feelings. Microsoft is no longer simply "giving money and cloud"—it's trying to diversify its AI assets by implementing models from Mistral and developing its own small language models in the Phi series. The market has finally realized that OpenAI is no longer Microsoft's secret weapon that guarantees automatic victory over competitors. Now it's a complex, expensive, and politically toxic asset that requires delicate management and constant readiness for the worst. Investors who once applauded every partnership announcement now anxiously watch to see if OpenAI will become the very anchor that drags Microsoft down in case of legal or technical collapse.

The bottom line: The era of unconditional trust in the Microsoft-OpenAI alliance has ended. Will Satya Nadella be able to maintain this fragile balance, or will we witness the most expensive and spectacular technology breakup of the decade?
