Elon Musk's xAI signed a $1.25 billion per month GPU compute deal with Anthropic, totaling $45 billion through 2029, making it one of the largest infrastructure contracts in AI history. Simultaneously, SpaceX filed for a $1.75 trillion IPO, the largest ever, with a 30% retail float and a specific insider unlock structure that will make early investor Antonio Gracias extraordinarily wealthy. Anthropic is now projected to turn profitable next month, beating OpenAI despite OpenAI's scale advantage.
The video is worth reading in full not for the headlines but for the structural details: the S1 filing breakdown, how Cursor's $60 billion acquisition by SpaceX positions Michael Truell as potentially the youngest billionaire alive, and how Composer 2.5, built on an open-source Kimi base, is outperforming Anthropic's Opus 4.7 and OpenAI's GPT 5.5 at a fraction of the cost. Claude Mythos also cracked Apple's M5 chip in five days for $35,000, a data point that reframes what AI-assisted security research looks like in 2025.
The episode closes on two items with long-term signal: China's GPU summit failure and its implications for the compute race, and Andrej Karpathy reportedly joining Anthropic. An OpenAI IPO filing is also rumored for this week. The concentration of capital, talent, and compute shifting in a single 48-hour window makes this episode a useful timestamp for where the industry stood.
