Anthropic's $30B Series G at $380B valuation with $14B ARR signals enterprise AI infrastructure consolidation, while WebMCP's structured API standard for agents and Qwen3's free 131K-context model shift competitive advantage from frontier models to orchestration layers and application lock-in. US export restrictions on H200 chips to China tighten semiconductor leverage in the AI supply chain amid ASML's record EUV orders, though AI16Z's unexplained 15.4% decline and KITE's 10.8% surge suggest repositioning within agent-stack valuations.
