• 💰 Nvidia is reportedly in talks to backstop up to $500 billion for a 10-gigawatt Stargate megasite in Ohio.
• 🏗️ Stargate added a new site in Georgia as of July 22.
• 🤝 Stargate is a roughly $500 billion, 10-gigawatt joint venture among OpenAI, SoftBank, Oracle, and MGX, with about 7GW and over $400 billion already committed over three years.
