Nvidia Shares Face Pressure Amid OpenAI Partnership Concerns

Nvidia US67066G1040

Nvidia's stock experienced volatility this week as reports surfaced regarding tensions with OpenAI, a key partner in the artificial intelligence sector. The chipmaker's shares fell approximately 3% on Monday before staging a modest recovery on Tuesday, gaining 0.75% to close at €158.12.

The reported friction with OpenAI highlights a significant structural challenge for Nvidia: its largest customers are increasingly becoming competitors. Major technology firms, including Microsoft, Amazon, and Google, are actively developing their own in-house semiconductor solutions to reduce reliance on external suppliers like Nvidia. OpenAI's exploration of alternative hardware aligns with this industry-wide trend.

Despite these partner-specific challenges, overall demand for AI infrastructure components remains robust. This strength was evidenced in Asian trading on Tuesday, where memory chip manufacturers Samsung Electronics and SK Hynix saw substantial gains of 11% and 9%, respectively. These advances were fueled by sustained, high demand for hardware essential to AI development.

Details of the OpenAI Dispute and a Scaled-Back Investment

According to information from Reuters, OpenAI has expressed dissatisfaction with the performance of Nvidia's graphics processing units (GPUs) for certain inference-related tasks. The developer behind ChatGPT has reportedly been actively seeking hardware alternatives since 2025.

A separate, potentially more significant development involves a planned major investment by Nvidia into OpenAI. Speculation had suggested this investment could reach up to $100 billion. However, reports indicate this deal has now been put on hold. Instead, Nvidia has directed $2 billion toward the cloud provider CoreWeave.

Nvidia CEO Jensen Huang has publicly dismissed narratives of a severed relationship with OpenAI as "nonsense." He did, however, acknowledge that any eventual investment figure would be substantially lower than the rumored $100 billion threshold.

Long-Term Strategic Outlook

The central question for investors is no longer whether demand for AI technology will persist—it clearly will—but rather how long Nvidia can maintain its current market dominance. The concerted efforts by hyperscale cloud companies to diversify their supply chains and develop proprietary technology signal that competition in the advanced chip sector is intensifying.

The coming quarters will reveal whether Nvidia can navigate these evolving partner dynamics while continuing to capitalize on the broader AI infrastructure boom.
