The AI infra market just got a $60B wake-up call, coding agents are multiplying fast enough to need their own development environments, and OpenAI’s honeymoon with Apple looks legally over. Let’s get into it.

🔥 Cerebras Hits $60B in Landmark IPO

Cerebras IPO: $60B Market Cap Validates Inference-First Hardware — Cerebras ($CBRS) closed at $280/share, hitting a $60B market cap after years as an ambitious but contentious wafer-scale chip bet. CFO Bob Komin claimed Cerebras is serving trillion-parameter models including internal OpenAI 5.4 and 5.5, reframing the company as a frontier inference platform, not just a niche accelerator. The IPO signals the market repricing AI infrastructure around inference economics rather than training prestige.

🤖 Coding Agents Proliferate

xAI Launches Grok Build — a Terminal-Based Coding Agent — xAI’s Grok Build enters early beta for SuperGrok Heavy subscribers with AGENTS.md, plugins, hooks, skills, MCP servers, subagents, and worktree integrations out of the box.
