The AI sector drew record capital as Elon Musk's xAI secured a $20 billion round at a $230 billion valuation, joined by Nvidia and others. Robotics firm Skild AI tripled its valuation to $14 billion, while chip startup Etched raised $500 million to challenge Nvidia. This investment frenzy underscores AI's dominance in venture capital.

Simultaneously, political moves reshaped semiconductor markets. President Trump imposed a 25% tariff on advanced chips like the Nvidia H200, while a U.S.-Taiwan deal promised $250 billion in reshoring investments. Memory giants SK Hynix and Samsung saw stocks surge on soaring demand for high-bandwidth memory essential for AI workloads.

Cybersecurity incidents proliferated, from alleged Instagram breaches to exposed WIRED subscriber data. Meanwhile, Anthropic's $10 billion funding at a $350 billion valuation and its new 'Claude Cowork' agent signal a shift from chatbots to proactive AI systems. Regulatory frameworks for crypto and AI are moving from discussion to implementation.
