OpenAI vs NVIDIA: The $100B Battle for Custom Chip Supremacy
Quick Navigation
For years, OpenAI and NVIDIA were the “Power Couple” of the AI revolution. ChatGPT runs on thousands of NVIDIA H100s. But recent reports suggest the honeymoon phase is over.
OpenAI is officially moving to design its own Custom AI Chips with Broadcom, aiming to break free from NVIDIA’s pricing stranglehold.
⚔️ The $100B Conflict
The core issue is simple: Cost. NVIDIA enjoys an 85% profit margin on its AI GPUs. For OpenAI, whose goal is AGI, paying “Apple-level” margins on hardware is unsustainable.
“We need more compute than exists on the planet right now.” — Sam Altman
While the companies are still negotiating a massive $100 billion “Stargate” data center project, OpenAI’s side-deal with Broadcom sends a clear signal: “We will build it ourselves if we have to.”
🔧 Project Broadcom: Custom Silicon
Reports confirm that OpenAI has secured manufacturing capacity with TSMC (3nm process) for a custom Inference Chip coming in 2026. Why Inference?
- Training (Teaching the model) still needs NVIDIA’s raw power.
- Inference (Running ChatGPT for users) can be done on cheaper, specialized chips.
By offloading inference to their own chips, OpenAI could slash operational costs by 30-50%.
| Strategy | NVIDIA H100 | OpenAI Custom Chip |
|---|---|---|
| Cost | $30,000+ per unit | Est. $10,000 unit cost |
| Availability | Massive Shortage | Controlled Supply |
| Role | Training & Inference | Inference Focused |
📉 Will NVIDIA Lose Dominance?
Unlikely in the short term. Google (TPU), Amazon (Trainium), and now OpenAI are all building chips, but NVIDIA’s CUDA software interface remains the industry standard moat.
However, if the biggest AI company in the world successfully migrates away, it proves that NVIDIA is not invincible.
