● The Brief

Good morning. OpenAI's release of its long-awaited GPT-6 Astra model didn't just make headlines in AI circles — it moved the market. CoreWeave jumped nearly 15%, and a broad swath of chipmakers, photonics firms, and cloud providers rallied Tuesday on the theory that a more capable model means more compute demand, not less. Nvidia's Jensen Huang added fuel by noting Astra was trained on 100,000 Blackwell GPUs, with 400,000 more coming online, a reminder of just how much physical infrastructure sits behind every model release now. Lumentum, Coherent, Corning, and Nebius all posted double-digit gains, which tells you this rally was about the whole AI supply chain, not just OpenAI itself. It's worth remembering that stock moves like this are bets on future demand holding up, not confirmation that it will. Below: today's five recent stories across markets, AI, policy, and security.
