Google Chief Executive Officer Sundar Pichai has issued one of the most candid warnings yet regarding the state of the artificial intelligence (AI) market, cautioning that no company—not even Google—would escape the fallout if the current AI investment boom collapses into a bubble.
Speaking from Google’s headquarters in Mountain View, California, Pichai described the rapid growth of AI as a transformational period in technology history, but warned that the pace and scale of investment have created undeniable signs of “irrationality” in the sector.
“We can look back at the internet right now. There was clearly a lot of excess investment, but none of us today would question whether the internet was profound,” Pichai said. “I expect AI to be the same. So I think it’s both rational, and there are elements of irrationality through a moment like this.”
He drew comparisons to the build-up to the dot-com crash of 2000, noting that valuations are rising faster than real-world adoption. Yet, he emphasised that such cycles are typical in periods of revolutionary technological innovation.
When asked whether Alphabet, the world’s second-most valuable tech company, could withstand a potential crash, Pichai was blunt: “I think no company is going to be immune, including us.”
AI Valuations Skyrocket
Alphabet’s valuation has more than doubled in just seven months, hitting $3.5 trillion, as investors place heavy bets on Google’s advancements in AI models and specialised chips that increasingly compete with Nvidia’s dominant hardware. Nvidia recently became the first company in history to reach a $5 trillion valuation, largely driven by global demand for its AI chips, intensifying market fears of overheating.
Analysts have also raised concerns over the $1.4 trillion in layered deals surrounding OpenAI, despite the company’s expected revenue for the year being a fraction of that amount. Experts warn that if OpenAI slows down, misses revenue targets, or faces regulatory hurdles, the broader AI ecosystem could face immediate consequences.
Pichai acknowledged these risks indirectly, highlighting the need for the sector to prepare for “overshoots” and corrections.
Alphabet’s Competitive Advantage
Despite the looming risks, Pichai emphasised that Alphabet is structurally better positioned than many AI startups due to its control of the entire AI stack. From data sources such as YouTube, to chips, model training infrastructure, and frontier research labs, Google has integrated capabilities that give it resilience against turbulence in the market.
“We own the full stack,” Pichai said, framing it as a competitive advantage that reduces dependency on external suppliers and limits exposure to financial shocks. However, he noted that even such an advantage cannot fully shield any company from a market-wide correction.
Global Investments and Strategic Partnerships
Pichai also highlighted Alphabet’s growing commitment to the United Kingdom, which is positioning itself as a global AI hub. Google recently announced a £5 billion investment into the UK’s AI ecosystem, aiming to expand infrastructure, research, and training of large AI models within British borders.
This move, which includes training some of Google’s large models in the UK for the first time, was welcomed by UK ministers seeking to make Britain the world’s third-largest AI “superpower”, behind the US and China.
“We are committed to investing in the UK in a pretty significant way,” Pichai said, describing the country as a long-term strategic partner for Google.
Energy and Sustainability Challenges
Pichai also warned about the global energy demands associated with AI growth. He revealed that AI systems consumed 1.5% of the world’s electricity in 2024, a figure expected to rise sharply as generative AI adoption expands.
“You don’t want to constrain an economy based on energy,” he said, urging governments worldwide to increase power generation and improve grid infrastructure. Pichai admitted that Google’s aggressive AI expansion has affected its progress toward climate and sustainability targets, though the company remains committed to achieving net-zero emissions by 2030.
Impact on Employment and Society
Describing AI as “the most profound technology” humanity has ever built, Pichai explained that it will transform every profession, from teaching and medicine to law and media. While some jobs will evolve or transition, those who embrace AI tools are likely to prosper, while others may face economic disadvantages.
He also predicted the emergence of entirely new classes of jobs, akin to the internet’s creation of industries that did not exist in the 1990s, underscoring the potential for AI to generate opportunities alongside disruption.
Regulatory and Market Scrutiny
Pichai’s remarks come amid unprecedented scrutiny of the AI sector. Regulators in the US, Europe, and Asia are examining everything from training data practices to market concentration, while investors debate whether the AI boom represents sustainable growth or a speculative bubble.
Analysts suggest that Pichai’s candid warning is one of the clearest acknowledgements by a major tech leader that the AI market may indeed be overheating.
Conclusion
The AI sector is entering a critical period, with extraordinary innovation, investment, and societal impact. Yet, as Pichai has noted, irrational valuations, energy concerns, and market dependencies serve as reminders that even the largest and most sophisticated companies, including Google, are not immune to potential corrections.
As AI continues to evolve, the technology promises profound transformations in business, work, and society, but it also demands careful navigation of financial, regulatory, and ethical risks to ensure that the opportunities outweigh the threats.
