AI Weekly Briefing: A Mega Round for OpenAI What It Signals for the Whole Market

This week I'm unpacking OpenAI's record-breaking $110 billion raise and what Amazon and NVIDIA's involvement tells us about a partner landscape that's shifting faster than most people realise. I also dig into Anthropic's $30 billion Series G, and why it's time to take that one seriously as a strategic bet. Then there's Apple quietly admitting it can't build AI fast enough, handing Siri's core logic to Google Gemini. Also, the hyperscaler spending numbers are extraordinary, and I explain why the energy and infrastructure story is just as important as what's happening at the model layer. Plus: a reality check on Microsoft Copilot's 3.3% penetration, the Snowflake and OpenAI data gravity play, Samsung's push to put Gemini on 800 million devices, and what a protest march through London's tech hub on a Saturday morning tells us about where the regulatory conversation is heading.
