Microsoft feared OpenAI would defect to Amazon and criticize Azure

Court documents from Musk v. Altman offer a rare, candid look at how one of the most important technology partnerships, between Microsoft and OpenAI, took shape. Microsoft's top executives, it turns out, were literally afraid of losing the young AI startup to competitors, and rushed to commit billions of dollars, driven by fear of missing the future.

Summer 2017: OpenAI's finest hour

July 2017. OpenAI had just achieved something that seemed technologically unthinkable: its neural-network bot beat a professional player at Dota 2, one of the most complex computer games, where machines had hopelessly lost to humans for years. It was a genuine milestone in the history of artificial intelligence, a signal that machines were beginning to grasp strategy and make decisions at a human level.

Satya Nadella, Microsoft's CEO, sent Sam Altman a congratulatory email. But Altman's reply was more surprising than the victory itself: he proposed that Microsoft put serious money into funding the next ambitious phase of OpenAI's AI research. This was not just an interesting contract. It was a strategic alarm bell for competitors, a hint that the stakes had risen.

Microsoft's fears about Amazon

The court documents show that Microsoft's leaders were literally trembling with worry. They feared that OpenAI could defect to Amazon, their main rival in cloud computing and infrastructure. At stake was not just a startup but an entire technological revolution. Their concerns were specific and interlinked:

• OpenAI could publicly criticize the Azure platform in the press and in interviews
• Amazon would get access to cutting-edge AI developments before Microsoft
• Microsoft would lose a strategic prize in the heating-up race for AI leadership
• The startup could diversify its partnerships and become independent of Microsoft

In the executives' internal correspondence, these fears sound sharp and strikingly blunt, which in itself reveals the real dynamics of corporate competition at the start of the AI boom. Nobody knew that ChatGPT would upend the industry five years later. But everyone sensed that something important was being born.

From fear to long-term partnership

In the end, Microsoft made a bold and expensive decision. It invested substantial sums in OpenAI, provided cloud infrastructure on Azure and ultimately became the startup's main investor. It was a desperate bet on the unknown: nobody knew whether abstract AI research would deliver real revenue and scientific breakthroughs within a few years.

But the calculation proved flawless. The partnership let OpenAI scale its research and computing power sharply, while Microsoft gained early access to emerging technologies. When OpenAI launched ChatGPT several years later, Microsoft was its main infrastructure partner and the primary beneficiary of its exponential growth. History has shown the fears were justified.

An investment in the future that paid off many times over

Over the past seven years, the decision has paid off many times over. ChatGPT, GPT-4 and the whole OpenAI ecosystem developed under Microsoft's wing. Today the partnership is one of the most expensive in IT history: Microsoft's investments in OpenAI run to tens of billions of dollars. Integrating ChatGPT into Copilot, Excel and Word gave Microsoft a huge competitive advantage. And this is only the beginning: both companies continue to deepen their cooperation and joint development.

What this means

The disclosure of the court documents shows that ordinary human emotions lie behind high-profile technology partnerships: fear of losing a strategic prize, the thrill of competition, a sense that what is at stake is not just a project but power over a future industry. For business, it is a reminder: when you see a revolutionary technology that could rewrite the rules of the game, you need to act decisively, bet big and believe in its potential, even when it is pure speculation. The story of Microsoft and OpenAI is exactly such a case.
