xAI wins federal Grok OneGov contract and releases Grok Build coding agent

xAI's federal OneGov deal makes Grok 4 and Grok 4 Fast available to all US agencies at a nominal $0.42 per agency through March 2027 — an aggressive, near-loss-leader pricing move to plant Grok across government before rivals lock in. The 18-month term and trivial per-agency cost signal xAI prioritizing footprint and reference customers over near-term revenue.

On the developer side, Grok Build launched in beta as a terminal coding agent supporting headless scripting and the Agent Client Protocol (ACP), with a Skills feature wiring in SharePoint, Outlook, GitHub, and Linear. ACP support is notable — it positions Grok Build to interoperate in the emerging multi-agent tooling ecosystem rather than as a walled garden, directly challenging Claude Code and OpenAI's Codex.

The combination plays to Elon Musk's distribution flywheel: government access plus dev tooling plus the Tesla/X consumer surface (where Grok V9 is rolling in). xAI also tapped a Starlink staffer to run its Grok training team, per Bloomberg, underscoring the org buildout.

Competitive context: the federal contract mirrors moves by OpenAI and Anthropic to win government share, and the near-zero pricing will pressure incumbents' gov deals. Caveats: government procurement at $0.42/agency raises questions about support, security review, and whether the price is sustainable — and Grok's content-moderation track record may draw scrutiny in federal use.
