Google parent Alphabet said Monday it planned to raise to $80 billion from stock sales to support funding a major expansion of its artificial intelligence (AI) infrastructure, with Warren Buffett's Berkshire Hathaway committing $10 billion as part of the deal.

The fundraising comes as Alphabet ramps up investment spending, with capital expenditures expected to reach $180-$190 billion in 2026 and set to rise further in 2027.

The move reflects a broader spending race gripping the technology industry.

Amazon, Microsoft, Alphabet and Meta are collectively on track to pour roughly $700 billion into AI data centers, chips and computing infrastructure this year as each scrambles to keep pace with soaring demand for AI services.

Google chief executive Sundar Pichai told investors last month that the company is "compute constrained in the near term," meaning it cannot build the necessary infrastructure fast enough to meet demand.
