Anthropic Is Winning Enterprise, OpenAI Refocuses, Microsoft Bets on Superintelligence

Today we’re covering the biggest AI stories of March 18th, 2026. OpenAI’s Applications CEO Fidji Simo called Anthropic’s enterprise dominance a “wake-up call” in a company-wide meeting, telling staff they can’t afford to be distracted by side projects while Claude Code and Cowork quietly took over the business market. Mistral launched Forge, a platform that gives enterprises the exact same training infrastructure the French AI lab uses internally — letting companies build custom models on their own data without ever exposing it. Plus, Microsoft overhauled its AI org chart, combining its fragmented Copilot teams under new leadership while freeing CEO Mustafa Suleyman to focus entirely on building superintelligence in-house, and a community workflow from a car owner who built an AI-powered vehicle maintenance logbook using Claude.
