Alphabet, Google’s parent company, has announced plans to sell $80bn worth of shares to fund its rollout of artificial intelligence.

Alphabet said on Monday that the equity offerings would finance the rollout of AI infrastructure needed to meet “unprecedented customer demand”.

The US tech giant said the fundraising drive included a deal to sell $10bn of stock to Berkshire Hathaway, the conglomerate led for six decades by legendary investor Warren Buffett.

The remaining $70bn will come from $30bn in underwritten offerings – a type of share issuance where a financial institution buys stock to sell on to investors – and $40bn in staggered sales on the open market.

“The company is experiencing strong demand for its AI solutions and services from enterprises and consumers, at levels that are exceeding the company’s available supply,” Alphabet said in a statement.

“By scaling its investments, the company seeks to expand its foundational infrastructure to support the significant growth opportunity ahead.”

Shares of Alphabet, which has a market capitalisation of more than $4.5 trillion, were down about 1 percent in after-hours trading following the announcement.

Like other Silicon Valley giants, Alphabet, whose AI business spans the Gemini family of assistants, data centres and cloud services, has committed eye-watering sums to AI-related infrastructure.

The company said in its most recent earnings call that it expected its capital expenditures to reach $180-190bn this year, and rise “significantly” in 2027.

US tech behemoths, such as Alphabet, Microsoft, Amazon and Meta, are expected to spend some $800bn on AI-related capital investment in 2026, according to an analysis by Goldman Sachs.

Troy Hooper, co-head of equity capital markets for the Americas at the financial intelligence provider Mergermarket, said Alphabet’s funding plans underscored the intensity of the race to lead the AI buildout.

“For hyperscalers, compute capacity is a direct driver of future revenue,” Hooper told Al Jazeera.

“By leaning into equity, Alphabet is bringing in permanent capital rather than burdening a balance sheet already absorbing record capex,” Hooper said, using the shorthand for capital expenditure.

Hooper said US tech giants have come to view underinvestment in AI as an “existential risk” and over-investment as “merely expensive”.

“The logic is simple: under-investing is an existential risk; over-investing is merely expensive. Microsoft, Amazon, and Meta are following the same calculus,” Hooper said.

“Ownership at scale lowers the marginal cost of training advanced models, building a moat smaller competitors will struggle to match. The message is clear: The winners of the AI era will be decided not just by algorithms, but by who owns the largest and most efficient compute platforms.” (Al Jazeera)
