👋 Hey there!

Nvidia just wrote OpenAI a $100 billion check—but here's the twist: OpenAI is using that money to buy Nvidia chips. This 'circular financing' deal represents either the smartest partnership ever or a warning sign of AI bubble economics. Plus: why this changes everything about AI infrastructure costs and competition. Let's decode the handshake heard around Silicon Valley.

💡 The $100 Billion Handshake: Nvidia and OpenAI's Circular Investment Deal

Here's the deal that made everyone question if AI partnerships have become too circular: Nvidia announced on September 22 a $100 billion investment in OpenAI to deploy 10 gigawatts of AI infrastructure—equivalent to 4-5 million GPUs—with one catch that has analysts concerned. OpenAI will primarily use this investment to lease Nvidia chips, essentially meaning 'Nvidia invests $100 billion in OpenAI, which then OpenAI turns back and gives it back to Nvidia,' as Requisite Capital's Bryn Talkington told CNBC (CNBC September 2025).

The scale is unprecedented: 10 gigawatts represents the power consumption of 10 nuclear reactors and will support OpenAI's path to 'superintelligence' starting with the first gigawatt deployment in late 2026 using Nvidia's Vera Rubin platform (OpenAI September 2025). Jensen Huang called it 'the biggest AI infrastructure project in history,' but the circular nature has sparked concerns about 'bubble-like behavior' from analysts who worry about Nvidia propping up its own market (Fast Company September 2025). The deal structure involves Nvidia buying non-voting OpenAI shares, then OpenAI using that capital to lease Nvidia hardware—creating a self-reinforcing loop that some compare to the dot-com era.

$100 billion total investment commitment, 10 gigawatts of power (10 nuclear reactors worth), 4-5 million GPUs equivalent to Nvidia's entire 2025 shipment

For developers, this reveals how intertwined the AI infrastructure has become—and how expensive. At $35 billion in Nvidia hardware per gigawatt of capacity, the economics suggest that building competitive AI infrastructure requires partnerships with Nvidia rather than alternatives (CNBC September 2025). The 'circular' nature also highlights a new AI reality: the biggest players are essentially financing their own ecosystem growth. When even OpenAI's president admits '$100 billion is a small dent' in what's needed for superintelligence, it signals that AI development costs are moving beyond what any single company can afford without creative financing arrangements.

Bottom line: Bottom line: When your biggest customer needs $100B to buy your products, investing in them isn't partnership—it's market creation, and that circular logic might define the next phase of AI development.

💰 Cost Watch

Infrastructure reality check: At $35 billion in hardware per gigawatt of AI capacity, building competitive infrastructure now requires nation-state level investments. For startups, this means cloud access becomes even more critical.

🔧 Quick Wins

🔧 Optimize for cloud efficiency: With hardware costs skyrocketing, focus on model efficiency and smart batching to reduce compute needs

🎯 Explore smaller models: While giants chase superintelligence, opportunity exists in specialized, efficient models for specific use cases

⚡ Monitor infrastructure costs: Track the true cost of AI workloads—the circular financing trend suggests prices may not reflect real economics
