Meta delivered first-quarter revenue and net profit that beat market expectations, but its shares fell more than 5 percent in after-hours trading after it announced plans to expand investment in AI data centres, The Wall Street Journal reported on April 29 local time.

Meta's first-quarter revenue rose 33 percent from a year earlier to $56.3 billion, the report said. Net profit was $26.8 billion. Both revenue and net profit topped analysts' estimates. Meta forecast second-quarter revenue of $58.0 billion to $61.0 billion, broadly in line with market expectations.

Meta plans capital spending of up to $145.0 billion this year. Most of it is expected to be used to build data centres for training and operating AI models.

Meta unveiled its AI model Muse Spark in early April. It was the first model it released after reorganising its AI team last year and appointing Alexandr Wang (알렉산드르 왕) as chief AI officer.

Muse Spark was assessed as on par with major rival models in both internal and external evaluations, the WSJ reported.

Meta plans to cut about 8,000 jobs, or about 10 percent of its workforce, to fund investment. It is also working to increase AI use among more than 70,000 employees. Last week, a researcher at Meta Superintelligence Labs said in an internal memo that the company would track employees' key inputs, mouse movements and click locations for use in training AI systems, which drew pushback from some employees, the WSJ reported.

Meta Chief Technology Officer Andrew Bosworth (앤드루 보스워스) said in a separate memo that AI agents would in the future take over employees' current tasks and employees would take on roles supervising and improving the agents.
