Anthropic Hits $380B Value as Microsoft Eyes Exit [Model Behavior]

Anthropic has reached a $380 billion valuation following a $30 billion Series G funding round led by GIC and Coatue. This move positions the startup alongside OpenAI and SpaceX as one of the world's most valuable private entities. Concurrently, Anthropic committed $20 million to Public First Action to advocate for AI regulation ahead of the 2026 elections, emphasizing export controls and safeguards for high-risk applications. In a significant industry shift, Microsoft AI lead Mustafa Suleyman confirmed plans for the company to develop its own frontier models to reduce its reliance on OpenAI. Meanwhile, OpenAI released GPT-5.3-Codex-Spark, its first production model running on Cerebras hardware, achieving 2,100 tokens per second. The episode also covers Goldman Sachs' deployment of Claude 4.6 for financial automation, Google's Gemini-focused Super Bowl marketing, and the Motion Picture Association’s legal demand for ByteDance to cease copyright infringement via its new Seedance 2.0 video model.

Anthropic has solidified its position as a dominant force in the AI sector, securing a $30 billion funding round that brings its valuation to $380 billion. This massive capital injection comes as the firm reports $14 billion in annualized revenue and aggressively pivots toward political advocacy with a $20 million donation for AI guardrails. In this episode, we also examine Microsoft's strategic move to build internal foundation models, potentially signaling the end of its exclusive dependence on OpenAI. Technical developments include OpenAI's high-speed Codex-Spark running on Cerebras chips and Goldman Sachs' deployment of autonomous agents to streamline banking operations.
