Google's $40bn hedge on Anthropic, OpenAI's workspace push, and a quiet Performance Max rule change you can't afford to miss

Send us Fan MailGoogle has committed up to $40bn to Anthropic — $10bn now in cash at a $350bn valuation, with $30bn more tied to performance milestones, plus five gigawatts of compute over five years. The story is not the headline number. It is what it tells us about who actually controls AI capacity, and where enterprise spend is consolidating.Anthropic's revenue run-rate has reportedly jumped from around $9bn at the end of 2025 to over $30bn this month. That growth is being driven primarily by enterprise and developer use of Claude — and it now comes days after Amazon committed up to $25bn. Compute, not models, is the bottleneck.OpenAI has launched Workspace Agents in ChatGPT Business, Enterprise, Edu and Teachers. They plug into Slack, Salesforce, Google Drive, Microsoft, Notion and Atlassian, replacing custom GPTs over time. Free until 6 May, then credit-based. This is the most operator-relevant launch of the week.Google has quietly moved Performance Max to asset-level disapprovals for any campaign created on or after 7 April. Most accounts are still running on muscle memory from the campaign-level era. This will silently degrade performance for anyone not monitoring asset health.Anthropic's Claude Design rolled out a week ago, generating decks, landing pages, prototypes and campaign visuals from prompts. Figma stock dropped 7% on the news. The creative production cost curve continues to bend — but the proof point is still thin.The dominant pattern across the day's news: capital, compute and distribution are concentrating into a tighter group of platforms, while the operational rule changes that actually move money in agencies are being shipped quietly, in the background.
