Berkshire Hathaway agreed to purchase a $10bn stake in Alphabet, anchoring the tech giant’s $80bn equity programme disclosed Monday. Goldman Sachs will place the private deal, while a broader suite of public offerings follows Alphabet’s SEC filing. The investment splits evenly between Class A shares at $351.81 and Class C shares at $348.20 per share, expanding Berkshire’s position built since late 2025.

Alphabet plans to underwrite $30bn of new shares, with Goldman Sachs, J.P. Morgan and Morgan Stanley acting as joint book‑runners. A separate $40bn at‑the‑market programme will be managed by the same trio. The combined offerings could dilute existing shareholders but provide capital for the company’s accelerated AI investments and competitive positioning.

By locking in a marquee investor, Alphabet signals confidence in its AI roadmap and secures a low‑cost funding source. The deal gives Berkshire Hathaway a sizable foothold in the sector while granting the Google parent flexibility to meet its multi‑year cash needs without over‑relying on market timing.

Investors will watch the pricing spread between the two classes, as the modest discount on Class C shares reflects Alphabet’s dual‑class structure. The infusion bolsters the balance sheet ahead of anticipated spending on generative AI chips and cloud services, reinforcing the company’s ability to compete with Microsoft and Amazon in the fast‑growing market.
