The unprecedented scale of the deals has reignited long-simmering fears of a “circular AI” economy, a self-reinforcing but potentially unsustainable cycle that has dominated the global tech sector since 2022. The circular AI framework refers to the current industry dynamic where nearly all capital flowing into the AI sector is ultimately funneled toward purchasing Nvidia’s high-end AI chips, as firms race to build out computing capacity to launch AI products and services. The revenue generated from those AI offerings is then reinvested in additional Nvidia hardware to scale operations, creating a closed loop that has driven Nvidia’s market capitalization to surpass $3 trillion as of mid-2024. Prior to this latest round of deal announcements, multiple Wall Street analysts had warned that the cycle was showing clear signs of overheating. Data from industry research firm PitchBook shows that 68% of generative AI startups still failed to turn a profit as of Q1 2024, even as they commit an average of 70% of their raised venture capital to AI chip purchases. The $750 billion in locked-in purchase commitments have amplified those concerns significantly, as many customers have agreed to fixed annual purchase volumes regardless of future demand for their AI services. Regulators in both the European Union and the U.S. Federal Trade Commission have launched preliminary reviews of the agreements, citing concerns that Nvidia’s locked-in control of both upstream semiconductor capacity (secured via exclusive long-term contracts with TSMC) and downstream customer demand could constitute anti-competitive behavior, shutting out rival chipmakers including AMD, Intel, and smaller AI chip startups from accessing key high-end market share. Nvidia executives have pushed back against the circular AI fears, stating in their latest earnings call that the contracted demand reflects real, unmet need for AI computing power across sectors including healthcare, finance, and manufacturing, rather than speculative investment. The company noted that 82% of the contracted deals are with profitable enterprise and cloud customers, rather than unprofitable startups, reducing the risk of widespread defaults. Still, industry analysts warn that even with a large share of deals with established firms, a 15% shortfall in global AI service revenue growth over the next three years could trigger more than $100 billion in write-downs across the tech sector, as companies are forced to pay for unused chip capacity.
