Meta's stock rose more than 3% after news surfaced that Mark Zuckerberg's company is planning to cut over 20% of its workforce to offset increased spending on artificial intelligence. The layoffs could affect around 15,000 workers and mark the largest job cuts since Meta cut more than 20,000 jobs in 2022 and early 2023 as part of its "year of efficiency" push. The company has not specified a date for the layoffs, but the magnitude of the round could change. The proposed cuts could generate about $6 billion in cost savings and a 5% boost to Meta's adjusted core earnings. The tech giant expects to spend as much as $135 billion in 2026, twice as much of what it did a year ago.
