Microsoft, Meta CEOs defend hefty AI spending after DeepSeek stuns tech world

Days after Chinese upstart DeepSeek revealed a breakthrough in cheap AI computing that shook the US technology industry, the chief executives of Microsoft and Meta defended massive spending that they said was key to staying competitive in the new field.

DeepSeek’s quick progress has stirred doubts about the lead America has in AI with models that it claims can match or even outperform Western rivals at a fraction of the cost, but the U.S. executives said on Wednesday that building huge computer networks was necessary to serve growing corporate needs.

“Investing ‘very heavily’ in capital expenditure and infrastructure is going to be a strategic advantage over time,” Meta (META.O), opens new tab CEO Mark Zuckerberg said on a post-earnings call.

Satya Nadella, CEO of Microsoft (MSFT.O), opens new tab, said the spending was needed to overcome the capacity constraints that have hampered the technology giant’s ability to capitalize on AI.

“As AI becomes more efficient and accessible, we will see exponentially more demand,” he said on a call with analysts.

Microsoft has earmarked $80 billion for AI in its current fiscal year, while Meta has pledged as much as $65 billion towards the technology.

That is a far cry from the roughly $6 million DeepSeek said it has spent to develop its AI model. U.S. tech executives and Wall Street analysts say that reflects the amount spent on computing power, rather than all development costs.

Still, some investors seem to be losing patience with the hefty spending and lack of big payoffs.

Shares of Microsoft — widely seen as a front runner in the AI race because of its tie to industry leader OpenAI – were down 5% in extended trading after the company said that growth in its Azure cloud business in the current quarter would fall short of estimates.

“We really want to start to see a clear road map to what that monetization model looks like for all of the capital that’s been invested,” said Brian Mulberry, portfolio manager at Zacks Investment Management, which holds shares in Microsoft.

Meta, meanwhile, sent mixed signals about how its bets on AI-powered tools were paying off with a strong fourth quarter but a lackluster sales forecast for the current period.

“With these huge expenses, they need to turn the spigot on in terms of revenue generated, but I think this week was a wake-up call for the U.S.” said Futurum Group analyst Daniel Newman.

“For AI right now, there’s too much capital expenditure, not enough consumption.”
There are some signs though that executives are moving to change that.

Microsoft CFO Amy Hood said the company’s capital spending in the current quarter and the next would remain around the $22.6 billion level seen in the second quarter.

“In fiscal 2026, we expect to continue to invest against strong demand signals. However, the growth rate will be lower than fiscal 2025 (which ends in June),” she said.
