Today’s episode covers Anthropic’s Claude Sonnet 5.5, Nvidia’s OpenShell agent-security system, new AI infrastructure deals, Meta’s enterprise AI push, SpaceX’s first Starship orbital success, the ETF market’s increasingly specialized products, fuel-economy rules, and workers paying for AI tools themselves.

AI models, agents, and safety

• Workplace AI: Morning Brew cites a Deloitte UK survey finding that about 63% of workers use AI regularly, with some paying for tools themselves or using them without their employers’ knowledge.

Infrastructure, acquisitions, and cost

• Anthropic signed a reported $11.6 billion infrastructure agreement with Akamai, potentially reaching $20 billion.

• Morning Brew reports that the FAA delayed Boeing 737 Max 10 certification while assessing a software issue that could create a landing-safety threat.

Markets and ETFs
