TLDR: Investors are increasingly scrutinizing the extent to which Nvidia’s own balance sheet and strategic investments are underpinning the current artificial intelligence boom. Concerns are rising about the sustainability of this growth, with some drawing parallels to past tech bubbles. Nvidia has made significant investments, including $100 billion in OpenAI and $5 billion in Intel, to bolster the AI ecosystem and secure its supply chain, while its market capitalization has soared past $4 trillion.
The unprecedented surge in the artificial intelligence sector has prompted a critical question among investors: how much of this boom is genuinely organic, and how much is being propped up by Nvidia’s own formidable balance sheet? This growing inquiry, highlighted by Fortune, suggests a rising apprehension about the sustainability of current AI valuations and the potential for ‘circular deals’ reminiscent of previous technology bubbles.
Nvidia, a bellwether for the AI era, has seen its stock performance described as nothing short of spectacular. In 2024, its shares reportedly surged by an astonishing 171.2% by year-end, crossing the $3 trillion market capitalization mark in June 2024 and briefly surpassing $4 trillion by August 2025, making it the largest listed U.S. company by market capitalization. The company’s consistent outperformance, with four consecutive quarters in calendar year 2024 beating analyst expectations in revenue and earnings, has further cemented investor confidence. For the third quarter of fiscal year 2025, Nvidia reported a record revenue of $35.1 billion, a 94% year-over-year increase, with its pivotal data center segment contributing a record $30.8 billion, up 112% year-over-year.
However, this meteoric rise is not without its complexities. Nvidia has strategically deployed its financial strength to cultivate and secure the broader AI ecosystem. Notable investments include a reported $100 billion in OpenAI to finance a historic data center build-out and a $5 billion investment in rival chip designer Intel. This approach, described as a ‘familiar play’ by CEO Jensen Huang, aims to leverage investor confidence to strengthen supply chain partners and keep the AI boom humming through deals, partnerships, and investments in key customers like cloud-computing provider CoreWeave and xAI.
Despite these impressive figures and strategic maneuvers, the market has experienced jitters. Nvidia’s stock has seen occasional pullbacks, including a 5% decline after its Q2 2024 earnings report and a roughly 1.5% decrease year-to-date in 2025. These fluctuations are attributed to broader macroeconomic pressures and geopolitical risks, particularly U.S. trade restrictions on advanced semiconductor exports to China, a historically significant market for Nvidia’s data center sales.
The euphoria surrounding AI has also ignited a fierce debate about the sustainability of current investment levels. A growing number of analysts and investors are voicing concerns, drawing parallels to previous market bubbles. The perceived ‘AI bubble’ is a significant worry, with critics arguing that soaring valuations are driven more by speculative excitement and lofty expectations than by proven revenues and robust business models. Even prominent figures like Sam Altman, CEO of OpenAI, have acknowledged that some company valuations appear ‘insane.’ An MIT report highlighted that a staggering 95% of companies investing in generative AI have yet to see measurable financial returns, and an equally high percentage of generative AI pilots fail to deliver anticipated ROI, suggesting that many organizations might be ‘scaling inefficiency.’

Corporate AI investment reached a staggering $252.3 billion in 2024, with global venture capital funding exceeding $100 billion. Global AI spending is projected to surge to nearly $1.5 trillion by 2025 and surpass $2 trillion by 2026, with estimates suggesting AI could contribute over $15 trillion to the global economy by 2030. While the long-term economic advantages of AI are vast, the immediate financial underpinnings and the role of key players like Nvidia in sustaining this growth remain a central point of investor discussion.
