Bill Gates Doubted Satya Nadella’s $1 Billion OpenAI Bet – Now Worth $135B to Microsoft

When Microsoft made a billion-dollar bet on OpenAI in 2019, not everyone was convinced it was money well spent. In fact, the company’s own co-founder and then-chairman, Bill Gates, reportedly cautioned CEO Satya Nadella that the investment could easily amount to “setting $1 billion on fire.”

Nadella revealed the early skepticism during a recent interview on the tech-focused YouTube channel TBPN, offering a rare glimpse into the internal deliberations surrounding one of the most transformative partnerships in tech history. At the time, OpenAI was a non-profit organization, and the sheer scale of the investment – coupled with the nascent stage of artificial intelligence – raised eyebrows even within Microsoft’s leadership.

“Remember this was a nonprofit, and I think Bill [Gates] even said, ‘Yeah, you’re going to burn this billion dollars,’” Nadella recalled. Despite the warning, Nadella and his team pressed forward, recognizing the potential of OpenAI’s work in transformers and large language models. He emphasized that while board approval was necessary given the investment’s size, convincing stakeholders wasn’t as difficult as one might expect. “It was not that hard to convince anyone that this is an important area,” he said.

The initial motivation for Microsoft wasn’t simply about chasing the next big thing in AI, though that was certainly a factor. The company saw the partnership as a strategic move to establish a foothold in the rapidly evolving field and, crucially, to bolster the capabilities of its Azure cloud platform. “We kind of had a little bit of high risk tolerance, and we said, ‘We want to go and give this a shot,’” Nadella explained.

Looking back, Nadella admits that even he couldn’t have foreseen the magnitude of the success that would follow. “In retrospect, who would have thought? I didn’t put in a billion dollars saying, ‘Oh yeah, this is going to be a hundred bagger,’” he said. The “hundred bagger” has, in fact, materialized. As of October 2025, Microsoft’s 27% stake in OpenAI, secured through subsequent investments totaling over $13 billion, was valued at approximately $135 billion following a company restructuring.

The relationship has evolved significantly since that initial $1 billion investment. While Microsoft initially held cloud exclusivity with OpenAI, that arrangement has been adjusted. OpenAI now has the freedom to source compute power from other providers, but remains committed to purchasing $250 billion worth of Azure services over time. This revised agreement, reported by The Information, reflects OpenAI’s growing independence and the competitive landscape of cloud computing.

The financial benefits for Microsoft are already becoming apparent. In January 2026, the company reported a $7.6 billion boost to its net income directly attributable to its partnership with OpenAI. This underscores the transformative impact of the investment, turning what some considered a risky gamble into a major revenue driver.

The story of Microsoft’s investment in OpenAI also highlights the role of internal champions within large organizations. According to a LinkedIn post by Guillermo Flor, Microsoft’s current CTO, Kevin Scott – a former Google engineer – was instrumental in advocating for the deal. Scott’s conviction, even in the face of skepticism from others on the board, proved pivotal in securing the investment and setting Microsoft on a path to AI leadership.

The success of the OpenAI partnership stands in stark contrast to Microsoft’s earlier misses in key tech sectors like search and mobile. Nadella, having “caught the last train out of town” to secure Microsoft’s position in the cloud, was determined not to repeat those mistakes. Bringing Scott on board, with his Silicon Valley perspective, was a deliberate strategy to ensure Microsoft remained attuned to emerging technologies.

The narrative surrounding AI isn’t without its complexities. While Microsoft and OpenAI are experiencing significant success, other players in the field, like Anthropic, are grappling with the challenges of balancing safety and commercial pressures. Recent reports also suggest that the widespread adoption of AI in the workforce isn’t necessarily leading to increased productivity, but rather to burnout among white-collar employees, as highlighted by research from UC Berkeley.

the competitive dynamics within the AI space are intensifying. The recent Super Bowl ad war between OpenAI and Anthropic, and the reported refusal of their CEOs, Sam Altman and Dario Amodei, to participate in a symbolic gesture of unity, underscores the growing tensions between these industry leaders.

Bill Gates himself has evolved in his perspective on AI. While initially wary of the OpenAI investment, he has since expressed a more optimistic view of the technology’s potential, even suggesting that AI will eventually automate many tasks currently performed by humans. “There will be some things we reserve for ourselves,” he told Jimmy Fallon on The Tonight Show last year, “But in terms of making things and moving things and growing food, over time those will be basically solved problems.”

The Microsoft-OpenAI story serves as a compelling case study in risk-taking, strategic foresight, and the unpredictable nature of technological innovation. It’s a reminder that even the most cautious voices can be proven wrong, and that sometimes, the biggest rewards come from betting on the seemingly impossible.
