Reports indicate Meta Platforms ($META) is building a cloud business to sell excess AI compute, a move that could justify heavy capex and diversify revenue beyond advertising. While a potential shift toward a full cloud model to compete with GOOGL, MSFT, and AMZN could increase capex and benefit semis, a bearish view suggests selling idle compute might signal lower future demand for CRWV, IREN, and the broader semiconductor sector. $META shares were recently seen trading at $604.93, up 7.52% in pre-market activity.
