Welcome to Markets Desk, here's what's moving the needle today.
Warren Buffett is flashing a familiar warning sign. The S&P five hundred is up roughly nineteen percent over the past six months, the Nasdaq nearly twenty-six. Buffett has seen this movie before — when price gains outrun earnings, the buyers who show up late tend to leave fast, and history has not been kind to that crowd.
Staying with the theme of overconfidence, OpenAI's Sam Altman is raising a different kind of alarm. He posted this week that he's deeply uncomfortable with people treating AI models as a substitute for human judgment — even calling it a real safety issue. When the man building some of the most powerful AI tools on earth says the reverence around them worries him, that is worth taking seriously.
Shifting to Capitol Hill, Vice President Vance has accused Microsoft of replacing laid-off American workers with foreign hires, a claim serious enough that the administration has barred Microsoft and seven other firms from sponsoring green cards. The actual visa data tells a more complicated story, and that gap between the political narrative and the numbers is where the legal and reputational risk lives for these companies.
That's the tape. Markets Desk, signing off the floor.
