MSFT Dips Overnight as Nadella Criticizes Anthropic's Fable 5 Guardrails

Microsoft shares fell 1.3% in overnight trading, erasing nearly all of Thursday's gains, while the stock remains up 7.5% in July alongside broader Big Tech strength. CEO Satya Nadella reportedly told employees that Anthropic's Fable 5 AI model is overly "editorially controlled," with guardrails that "don't make sense" for a creation tool.

Why it matters: Fable 5 and its parent model Mythos have faced scrutiny after the U.S. government ordered restrictions on foreign access, prompting a temporary withdrawal before Anthropic restored them with enhanced safeguards.
