Cheap Chinese AI, agentic coding, and giant infrastructure deals
Reasoning models became the industry’s center of gravity. DeepSeek’s low-cost, open-weight R1 arrived in January and took $589 billion off Nvidia’s market value within a week, days after OpenAI, SoftBank, and Oracle announced a $500 billion American data-center venture. Coding agents such as Claude Code, Codex CLI, and Cursor turned into daily tools. Washington rescinded the Biden administration’s AI safety order while Brussels began applying the AI Act to general-purpose models. Two federal judges held that training on lawfully acquired books was fair use, and Anthropic paid about $1.5 billion to settle piracy claims. OpenAI reached a $500 billion valuation, Anthropic $183 billion, and Amazon cut 14,000 jobs with AI among the reasons given.
