IBM CEO Arvind Krishna was skeptical of the "belief" that data center spending could be profitable. Riccardo Savi/Getty Images for Concordia Annual Summit 2025-12-02T10:30:10.362Z Share Facebook Email X LinkedIn Reddit Bluesky WhatsApp Copy link lighning bolt icon Impact Link Add us on
This story is available exclusively to Business Insider IBM's CEO walked through some napkin math on data centers— and said that there's "no way" to turn a profit at current costs. AI companies are spending billions on data centers in the race to AGI. IBM CEO Arvind Krishna has some thoughts on the math behind those bets. Data center spending is on the rise. During Meta's recent earnings call, words like "capacity" and AI "infrastructure" were frequently used. Google just announced that it wants to eventually build them in space. The question remains: will the revenue generated from data centers ever justify all the capital expenditure?On the "Decoder" podcast, Krishna concluded that there was likely "no way" these companies would make a return on their capex spending on data centers. Couching that his napkin math was based on today's costs, "because anything in the future is speculative," Kirshna said that it takes about $80 billion to fill up a one-gigawatt data center."Okay, that's today's number. So, if you are going to commit 20 to 30 gigawatts, that's one company, that's $1.5 trillion of capex," he said. Krishna also referenced the depreciation of the AI chips inside data centers as another factor: "You've got to use it all in five years because at that point, you've got to throw it away and refill it," he said. Investor Michael Burry has recently taken aim at Nvidia over depreciating concerns, leading to a downturn in AI stocks. "If I look at the total commits in the world in this space, in chasing AGI, it seems to be like 100 gigawatts with these announcements," Krishna said.At $80 billion each for 100 gigawatts, that sets Krishna's price tag for computing commitments at roughly $8 trillion. "It's my view that there's no way you're going to get a return on that, because $8 trillion of capex means you need roughly $800 billion of profit just to pay for the interest," he said.Reaching that number of gigawatts has required massive spending from AI companies — and pushes for outside help. In an October letter to the White House's Office of Science and Technology Policy, OpenAI CEO Sam Altman recommended that the US add 100 gigawatts in energy capacity every year. "Decoder" host Nilay Patel pointed out that Altman believed OpenAI could generate a return on its capital expenditures. OpenAI has committed to spending some $1.4 trillion in a variety of deals. Here, Krishna said he diverged from Altman."That's a belief," Krishna said. "That's what some people like to chase. I understand that from their perspective, but that's different from agreeing with them." Krishna clarified that he wasn't convinced that the current set of technologies would get us to AGI, a yet to be reached technological breakthrough generally agreed to be when AI is capable of completing complex tasks better than humans. He pegged the chances of achieving it without a further technological breakthrough at 0-1%.Several other high-profile leaders have been skeptical of the acceleration to AGI. Marc Benioff said that he was "extremely suspect" of the AGI push, analogizing it to hypnosis. Google Brain founder Andrew Ng said that AGI was "overhyped," and Mistral CEO Arthur Mensch said that AGI was a "marketing move." Even if AGI is the goal, scaling compute may not be the enough. OpenAI cofounder Ilya Sutskever said in November that the age of scaling was over, and that even 100x scaling of LLMs would not be completely transformative. "It's back to the age of research again, just with big computers," he said.Krishna, who began his career at IBM in 1990 before rising to eventually be named CEO in 2020 and chairman in 2021, did praise the current set of AI tools. "I think it's going to unlock trillions of dollars of productivity in the enterprise, just to be absolutely clear," he said.But AGI will require "more technologies than the current LLM path," Krisha said. He proposed fusing hard knowledge with LLMs as a possible future path. How likely is that to reach AGI? "Even then, I'm a 'maybe,'" he said.

IBM CEO Arvind Krishna has expressed significant skepticism regarding the projected profitability of the current massive investment in artificial intelligence infrastructure, specifically data center development. His assessment, detailed during a conversation with “Decoder” podcast host Nilay Patel, centers on a rather stark calculation of capital expenditure (CapEx) and the likely inability of current AI companies to generate sufficient returns. Krishna’s argument revolves around a “napkin math” exercise, estimating that approximately $8 trillion in CapEx is currently being committed to building and operating data centers aimed at supporting the pursuit of Artificial General Intelligence (AGI). To simply cover the interest on this investment—estimated at $800 billion—would require a staggering $8 trillion in profit. This highlights the immense financial burden associated with the current trajectory of AI development. The CEO’s concerns are further underscored by his assessment of the likelihood of AGI being achieved through current technological approaches. He places the probability of realizing AGI without a significant technological breakthrough at a remarkably low 0-1%. This assessment is supported by a growing chorus of prominent figures in the AI field, including Marc Benioff, who views the AGI push with skepticism, Andrew Ng, who describes it as “overhyped,” and Arthur Mensch, who frames it as a “marketing move.” Furthermore, Ilya Sutskever, a co-founder of OpenAI, has suggested that simply scaling Large Language Models (LLMs) 100 times over won’t deliver transformative results, returning the field to an era of focused research. Krishna’s calculation isn’t just theoretical. The scale of investment is driven by ambitious goals, exemplified by OpenAI’s recommendation to the White House’s Office of Science and Technology Policy to add 100 gigawatts of energy capacity annually. This highlights the level of commitment—and perceived need— surrounding AGI development. Despite this skepticism, Krishna acknowledges the potential productivity gains unlocked by current AI tools, anticipating trillions of dollars in enterprise productivity. However, he believes that reaching AGI will necessitate “more technologies than the current LLM path,” advocating for a fusion of hard knowledge with LLMs as a potential future direction. While suggesting a cautious, measured approach, he concedes “it’s back to the age of research again, just with big computers”. Ultimately, Krishna’s viewpoint paints a picture of significant financial risk, coupled with a recognition of the evolving nature of the technology, demanding a more nuanced strategy than simply massive infrastructure investment. |
