Alphabet's (GOOG) $84.75B equity raise, including a $10B investment from Berkshire Hathaway (BRK.A), highlights the unprecedented scale of AI infrastructure spending while also reflecting exceptionally strong cloud demand, supported by a rapidly growing Google Cloud backlog and accelerating AI product adoption, TD Cowen analyst John Blackledge tells investors in a research note. The firm reiterates a Buy rating and $450 price target on the shares.
