"Snap stock" is trending primarily due to two significant developments: its recent financial performance and a major strategic partnership involving artificial intelligence (AI).

First, Snap Inc., the company that owns the popular app Snapchat, recently announced its earnings for the third quarter of 2025. These results were better than what financial experts had expected, showing that the company's revenue increased and its losses were smaller than before. This positive financial news often makes investors more confident, leading to increased interest and activity around the company's stock. Snap also reported an increase in the number of people using its app daily and monthly, and they announced a plan to buy back some of their own stock, which can also signal financial strength and boost investor confidence.

Second, and adding significantly to the trend, Snap Inc. revealed a substantial partnership with an AI company called Perplexity AI. As part of this $400 million deal, Perplexity's AI-powered search engine will be built directly into Snapchat's chat feature starting in early 2026. This news, announced alongside the strong earnings report, caused a considerable jump in Snap's stock price after regular trading hours. This partnership highlights Snap's commitment to integrating advanced AI into its platform, a move that is highly valued by the tech and financial markets.

More broadly, there's significant excitement and investment in AI technologies across the entire tech industry. Companies are using AI to improve everything from user experience and advertising effectiveness to market analysis. Perplexity AI is a company recognized for its innovative AI-driven search capabilities, and its collaboration with a major platform like Snapchat signals a growing trend of AI integration in popular consumer applications. This broader interest in AI and its potential impact on tech companies further contributes to why "snap stock" is a trending topic.
