OpenAI Misses Growth Targets: OpenAI reportedly fell short of internal ChatGPT user and revenue goals, rattling investors and sending Nvidia, AMD, Oracle, and CoreWeave shares lower in pre-market trading. Anthropic Surpasses $1 Trillion Valuation: Secondary market demand for Anthropic shares has pushed its valuation to $1 trillion on Forge Global, now trading above OpenAI despite OpenAI's larger official valuation of $852 billion. Taylor Swift Trademarks Her Voice and Likeness: Swift filed three U.S. trademark applications covering specific spoken phrases and a stage performance image, aiming to establish legal protection against unauthorized AI-generated deepfakes. Legal experts note Swift's approach of trademarking her voice is unprecedented in court, but could set a new legal standard for how public figures protect their identities in the AI era.
