Meta Platforms Inc. announced that its social media app Threads has surpassed 400 million monthly active users (MAUs), marking an increase of 50 million since April when it had 350 million MAUs. This milestone highlights Threads' rapid growth and its emerging position as a strong competitor to Elon Musk's social media platform X. Despite Threads' growth, mobile daily active users (DAUs) on Threads were reported at 15.3 million in June, still below X's 22.9 million DAUs. The rise in Threads' user base has contributed to a 3% increase in Meta's stock price, which recently exceeded $800. Meanwhile, Bluesky, another competitor to X, has implemented a comprehensive update to its policies and Community Guidelines to comply with new regulations including the European Union's Digital Services Act (DSA), the United Kingdom's Online Safety Act, and the United States' Take It Down Act.
