Meta's Q3 2026 headcount will reflect the impact of its May 2026 restructuring, which targeted approximately 8,000 roles—about 10% of the workforce—as the company reallocates resources toward artificial intelligence infrastructure and efficiency initiatives. Official filings show 75,472 employees as of June 30, 2026, with the note that most of those impacted by the reduction would exit the reported headcount by quarter-end. This follows earlier workforce optimization efforts amid heavy AI spending. Traders are watching for the Q3 earnings release, expected around October 21, which will disclose the final figure and clarify any additional adjustments or hiring trends in engineering and product teams.
