MOUNTAIN VIEW, California: Alphabet has increased the size of its planned equity offerings to US$84.75 billion, underscoring strong investor demand as major technology companies pour billions of dollars into artificial intelligence infrastructure.

The Google parent had announced earlier this week that it planned to raise $80 billion to expand data centers and computing capacity in the intensifying race to develop advanced AI systems.

According to a regulatory filing dated June 2, Alphabet now plans to raise $18 billion through sales of Class A and Class C shares, along with $16.75 billion through depositary shares.

The company had previously expected to raise $30 billion through concurrent public offerings, split evenly between the two offerings, each backed by investment banks.

Alphabet's plans to secure an additional $10 billion through a private share placement to Berkshire Hathaway and another $40 billion through an at-the-market stock offering program later in the third quarter remain unchanged.

The company said the stock offerings are expected to close on June 4, while the depositary share sale is scheduled to be completed a day later.

The expanded fundraising effort comes as technology giants accelerate spending on AI infrastructure, including data centers, chips, and computing networks needed to support increasingly powerful AI models.

In April, Alphabet raised its annual capital expenditure forecast by $5 billion, bringing planned spending for the year to between $180 billion and $190 billion.

The company is among a growing number of technology firms turning to capital markets to fund AI investments. Historically, Silicon Valley's largest companies relied heavily on cash reserves to finance expansion, but the scale of current AI spending has prompted many to seek additional funding through both debt and equity offerings.

Industry-wide spending continues to surge as companies compete to build the computing infrastructure needed for the next generation of AI products and services.

Combined spending by major technology firms is now expected to exceed $700 billion this year, up from previous estimates of about $600 billion.

The increase highlights the growing financial commitment behind what many executives have described as a once-in-a-generation technological race, with companies investing heavily to secure leadership positions in artificial intelligence.
