AI Weekly Briefing: Is NVIDIA Finally Getting Real Competition?

Cerebras went public at a $95 billion market cap, the biggest tech IPO since Snowflake and the first pure-play AI hardware listing of this cycle. The reference point for every NVIDIA challenger just got a lot more expensive. Plus, Anthropic's reportedly closing a $30 billion raise at a $900 billion valuation, which puts it level with OpenAI and ends the smaller-alternative framing for good. Cisco posted record AI orders and announced 4,000 layoffs in the same week, which is starting to feel like the new normal.  Notion is pitching itself as an agent hub rather than a documents tool. And Microsoft's M-DASH multi-agent system beat Anthropic on a cybersecurity benchmark using more than 100 coordinated agents, which suggests the winning pattern isn't one giant model. It's a team of smaller ones doing specific jobs well. We'll also touch on Anthropic going downmarket with Claude for Small Business, Boomi's on-prem agent runtime aimed at regulated buyers, and why Mustafa Suleyman's claim that AI will automate most professional work in 12 to 18 months lands awkwardly against Copilot's 3.3% paid seat share.
