Event summary

Microsoft's stock declined by nearly 3% following a letter from a bipartisan group of state attorneys general expressing concerns about AI chatbots. The letter warned major tech companies, including Microsoft, about "sycophantic and delusional outputs" and child safety issues, calling for immediate action and independent auditing. Despite this regulatory pressure, the article suggests Microsoft will likely find a way to operate effectively, as it has with past regulatory challenges.
