New AI models are designed to perform well on available, dominant hardware like NVIDIA's GPUs. This creates a self-reinforcing cycle where the incumbent hardware dictates which model architectures succeed, making it difficult for superior but incompatible chip designs to gain traction.

While known for its GPUs, NVIDIA's true competitive moat is CUDA, a free software platform that made its hardware accessible for diverse applications like research and AI. This created a powerful network effect and stickiness that competitors struggled to replicate, making NVIDIA more of a software company than observers realize.

Seemingly strange deals, like NVIDIA investing in companies that then buy its GPUs, serve a deep strategic purpose. It's not just financial engineering; it's a way to forge co-dependent alliances, secure its central role in the ecosystem, and effectively anoint winners in the AI arms race.

If NVIDIA's CEO truly believed AGI was imminent, the most rational action would be to hoard his company's chips to build it himself. His current strategy of selling this critical resource to all players is the strongest evidence that he does not believe in a near-term superintelligence breakthrough.

NVIDIA's vendor financing isn't a sign of bubble dynamics but a calculated strategy to build a controlled ecosystem, similar to Standard Oil. By funding partners who use its chips, NVIDIA prevents them from becoming competitors and counters the full-stack ambitions of rivals like Google, ensuring its central role in the AI supply chain.

NVIDIA funds OpenAI's compute purchases (of NVIDIA chips) with an equity investment. This effectively gives OpenAI a discount without lowering market prices, while NVIDIA gains equity in a key customer and locks in massive sales.

NVIDIA's deal with inference chip maker Grok is not just about acquiring technology. By enabling cheaper, faster inference, NVIDIA stimulates massive demand for AI applications. This, in turn, drives the need for more model training, thereby increasing sales of its own high-margin training GPUs.

Beyond selling chips, NVIDIA strategically directs the industry's focus. By providing tools, open-source models, and setting the narrative around areas like LLMs and now "physical AI" (robotics, autonomous vehicles), it essentially chooses which technology sectors will receive massive investment and development attention.

NVIDIA investing in startups that then buy its chips isn't a sign of a bubble but a rational competitive strategy. With Google bundling its TPUs with labs like Anthropic, NVIDIA must fund its own customer ecosystem to prevent being locked out of key accounts.
