Today’s TLDR rundown covers SpaceX’s IPO oversubscribed by more than four times, OpenAI prepping steep token-price cuts ahead of an AI price war with Anthropic, and Stack Overflow’s new API-first knowledge platform for AI agents. Plus quick briefs on gene-therapy vision reversal and China’s first commercial brain implant.

• SpaceX's IPO was oversubscribed more than 4x, selling 555.6M shares at $135 each—set to be the biggest IPO in U.S. history if it holds
• OpenAI is preparing to cut token prices to match Anthropic, risking thinner margins for both as they burn cash on GPU costs
• Stack Overflow launched an API-first "Stack Overflow for Agents" platform using multi-agent loops and trust scores to keep docs accurate for AI agents
• China approved NeuraMatrix's NEO brain-computer interface for commercial use, putting it ahead of Neuralink's N1, which remains stuck in U.S. research trials
