Nvidia Circular Investment Model Draws Scrutiny

Nvidia's dominance in AI chips has spawned a potential valuation trap: the company is directly funding or investing in the infrastructure companies that buy its products. CoreWeave, backed by Nvidia capex deals worth hundreds of millions, has become a major Nvidia customer. IREN (Iren Holdings), a compute infrastructure startup, announced a strategic partnership with Nvidia under which Jensen Huang stated: 'If we didn't support Iren exist, they would not exist. If we didn't help CoreWeave exist, they would not exist.' This circular dependency is now the focus of bear cases.

The structural issue is that Nvidia's near-term revenue growth depends on its own funded customers scaling. If Nvidia cuts funding, these startups' cash burn accelerates and capex orders crater. Conversely, if the broader generative AI training cycle moderates or if competition from AMD on inference accelerates, the entire ecosystem stalls. Goldman Sachs reiterated its bullish stance but highlighted five catalysts to watch at Nvidia's earnings call, hinting that management clarity on customer sustainability is critical.

Infrastructure plays like IREN, AVGO (Broadcom), and SMCI have traded on the assumption that AI capex is a decade-long supercycle. However, if Nvidia's own balance sheet constraints force it to reduce vendor financing or capex support, these companies face sudden demand destruction. The risk is asymmetric: upside remains if Azure, AWS, and Meta sustain spending; downside is severe if growth slows and circular financing dries up.

Investors are torn. Jim Cramer notes that Nvidia is 'tough to beat' and GOOGL, AMZN still have opportunities in full-stack deployments. However, portfolio managers are also trimming semis exposure and rotating into broader mega-cap tech, signalling caution on the infrastructure bubble narrative.
