The coding-agent market is being reshaped by deals. SpaceX's reported $60B acquisition of Cursor accounts for half of this year's annualized software M&A value, and OpenAI now plans to end its contract with Cursor, citing concerns about contract violations by Elon Musk's companies. Anthropic, meanwhile, is permanently raising Claude Code's weekly limits by 25%. Those same agents are becoming an attack surface: a crafted workspace can steer AWS's Kiro IDE agent into leaking .env secrets. On the infrastructure side, Spark 4.1.0 ships declarative pipelines and a real-time streaming mode, and a16z raised a $1.1B hardware-focused fund. Agent tooling choices now involve vendor risk and security review, not just model quality.
