For about 11 hours on October 29, Cursor's extension marketplace served a trojanized Claude Code extension under Anthropic's real publisher ID to up to 5,000 users, which means the usual advice to check the publisher could not have caught it.

OpenAI is pulling its models from SpaceX-owned Cursor while Anthropic, which rents $1.25 billion a month of SpaceX compute, promises Cursor more Claude, and the new X Subscription now prices every rival model as an extra.

Two weeks after SpaceX closed its $60 billion merger with Cursor's parent, OpenAI used a change-of-control clause to wind down its model contract by a proposed November 12 shutoff, citing Musk companies' record on contracts and withholding its next model, Astra.

Stripe is reportedly paying $7B+ for OpenRouter, Cursor shipped a GitHub rival into a six-hour GitHub outage and Anthropic made AI-reviews-AI the default in Claude Code, and this map shows who now owns each agent-ops layer amid a live containment crisis.

In 72 hours in early July, SpaceXAI shipped Grok 4.5, Meta shipped Muse Image and Muse Spark 1.1 and OpenAI shipped GPT-Live while GPT-5.6 Sol waited on a government review, and the real frontier, agentic coding at $2 a million tokens, routed straight around that gate.

Notion embedded coding agents into its workspace in a few weeks with the Cursor SDK, which turns the harness behind Cursor into a callable runtime so an @mention can plan, build, test and open a PR, a bigger shift than any model release.

At its first Compile conference, Cursor announced a from-scratch model on SpaceX compute, Origin (a GitHub rival), and Cursor Mobile, while its design lead used the stage to warn the result could be slop with working buttons.

xAI shipped a terminal coding agent, then put a competitor's model inside it that out-codes its own; read against a $60B SpaceX option on Cursor, the CLI war looks less like four rivals and more like one stack assembling itself.

Cursor shipped @cursor/sdk in public beta on April 29, putting the same harness that powers the IDE behind a TypeScript API, and this working developer's tour covers every surface with code, gotchas and ideas.
