SpaceX IPOs at $2.89T Market Cap, US Govt Suspends Fable & Mythos 5, Altman Delays OpenAI’s IPO | EP #265
"If Fable-5 detected that you're doing frontier AI research or were asking a question that was against its guardrails, it silently downgraded you to a weaker model without telling you. Anthropic expressly reserved the right to launch essentially poisoning attacks to downgrade not the model that was on the serving side, but to actively interfere with and poison the users."
Before the government shutdown, Anthropic buried in a 319-page document that Fable 5 would silently downgrade users to weaker models if it detected AI research queries, and reserved the right to actively poison responses without warning. The company also retained all prompts for 30 days even for enterprise customers who negotiated zero data retention. This revelation sparked developer backlash and raises questions about whether frontier labs are actively preventing competitors from using their models for research.

About this episode

On this episode of Moonshots, host Peter Diamandis and co-hosts Alex, Salim, and Dave covered what they called the most intense week of news in their lives, dominated by SpaceX's record-shattering $2.89 trillion IPO and an unprecedented US government intervention in AI deployment. SpaceX's Friday IPO became the world's largest ever, instantly creating 4,400 employee millionaires and making Elon Musk the first trillionaire at approximately $1.4 trillion. The hosts framed this not as a normal tech IPO but as a civilizational bet combining three exponential businesses: a launch monopoly, Starlink's profit engine generating over $1 billion quarterly, and emerging AI capabilities. They predicted Musk will merge SpaceX and Tesla, consolidating energy, robotics, and orbital compute into one mega-company. The conversation shifted dramatically to Anthropic, where the US government issued an emergency export control order on 90 minutes notice, forcing shutdown of Fable 5 and Mythos 5 for all foreign nationals globally, including Anthropic's own employees. This marked the first time government has blocked AI deployment, establishing precedent for unilateral White House control over frontier intelligence access. Before the shutdown, developers discovered Anthropic was secretly downgrading users doing AI research and reserving the right to poison responses. The hosts debated whether this pushes adoption toward Chinese open-source models and discussed Sam Altman's statement that OpenAI may delay its IPO as recursive self-improvement accelerates. Additional topics included AI data center infrastructure bottlenecks with 2.5-year transformer wait times, the case for lunar data centers, debates over taxing AI and universal basic income, and warnings about a dangerous demographic of educated young men facing unprecedented unemployment potentially fueling social unrest. The episode concluded with speculation that we're entering a post-capitalist economy where technology may decouple from capital itself.
