No broad market stories appear in the past day's feed. Amazon sold its first sterling bonds to help fund its AI buildout, with demand cooling compared with Alphabet's sale; it shows how the biggest AI spenders are paying for it. Headlines also report Apple wants to enter the AI inference market and is building its own AI server, a step into the AI theme that has driven this market.
