Alphabet increases planned equity offering to $84.75 billion, up from $80 billion, to fund AI infrastructure and data centers.

Alphabet raised its planned equity offering to $84.75 billion, up from the $80 billion plan announced earlier in the week. The company also received a $10 billion private investment from Berkshire Hathaway.

Alphabet plans to use the money to support data centers, cloud capacity and AI computing power. The company has already raised its annual capital spending forecast to $180 billion to $190 billion.

The larger raise suggests investors are still willing to back Big Tech's expensive AI buildout. Alphabet now has to prove that this spending can turn into stronger growth across Google Cloud, AI tools and search.
