Welcome to the first AI Mastery Hub weekly update. If you only read one thing this week, make it the Anthropic funding story — it changes the competitive landscape entirely.
Top Stories
1. Anthropic Raises $65 Billion at $965 Billion Valuation
The largest private AI funding round in history. Anthropic's $65B equity raise at a $965B post-money valuation surpasses OpenAI's $852B private valuation for the first time.
What matters: Anthropic is now projecting $10.9B in Q2 2026 revenue (up 130% quarter-over-quarter) and their first operating profit of ~$559M. They also secured a $36B credit facility — backed by Apollo and Blackstone — to buy Google TPU chips for massive data center builds.
What this means for you: When companies are spending $100B+ on compute in a single quarter, the tools you use today will be radically more capable within 12 months. Bet on the ecosystem, not individual products.
2. GPT-5.5 Instant Becomes Default ChatGPT Model
OpenAI quietly shipped GPT-5.5 Instant as the default ChatGPT model. The update brings sharper accuracy, more natural conversation flow, and fewer overly long responses.
Try this: Ask GPT-5.5 to explain a concept you understand well. Notice the difference in tone.
3. GitHub Copilot's Token Billing Backlash
GitHub switched from flat-rate ($29/month) to token-based billing. One user reported a projected $750/month cost. The takeaway: Efficient prompting is now directly tied to your monthly bill.
