TLDR: Reddit’s stock experienced a significant drop on October 1, 2025, following reports that OpenAI’s ChatGPT is substantially reducing its dependency on user-generated content from the platform. Data from AI search engine tracker Promptwatch indicated a sharp decline in Reddit content citations by ChatGPT, raising concerns about Reddit’s future data licensing revenue and strategic value in the AI landscape.
Reddit (NYSE: RDDT) witnessed a substantial downturn in its stock market performance on October 1, 2025, with shares tumbling over 9% in pre-market trading and as much as 12% during the day, closing at $208.20.
This sharp decline has drawn considerable investor attention and sparked questions regarding the platform’s long-term strategic value, particularly within the rapidly evolving artificial intelligence sector.
The precipitous drop in Reddit’s stock is primarily attributed to growing concerns that OpenAI’s widely used ChatGPT is increasingly reducing its reliance on Reddit as a primary source for generating responses.
Marketing strategist Andrea Bosoni highlighted this critical shift, noting a discernible decrease in ChatGPT’s traffic directed towards Reddit.
Further corroborating this trend, data from AI search engine tracker Promptwatch revealed a significant change in ChatGPT’s content sourcing.
On October 1, 2025, ChatGPT reportedly cited content from Reddit in less than 2% of its responses. This marks a substantial decline from a peak of 14% recorded in September, and a notable drop from 9.7% on August 31. This shift suggests a potential strategic pivot by OpenAI towards more curated and reliable datasets, moving away from Reddit’s often ‘messy’ or AI bot-laden user-generated content, which some critics describe as ‘poor at best and downright cringeworthy due to safety concerns.’
This development places Reddit, a key player in the social media and content aggregation space, at a critical juncture. While Reddit has successfully secured lucrative data licensing agreements, including a reported $60 million contract with Google (NASDAQ: GOOGL) and ongoing preliminary discussions with Alphabet Inc. for content licensing, the perceived reduction in its utility for major AI models like ChatGPT could significantly impact future revenue streams and its strategic importance within the broader AI economy.
The company’s exceptionally high price-to-earnings ratio further amplifies investor scrutiny in light of these developments.
Trading volume for Reddit shares was notably high, with over 9.79 million RDDT shares changing hands by 12:30 pm ET, representing 1.5 times its three-month average trading volume of 6.67 million.
Short interest on the stock stood at 14.60%.
While Reddit has seen its citation frequency lowered, it remains one of the top sources for ChatGPT citations. However, the study also indicated that Wikipedia, ChatGPT’s primary knowledge source, also saw a decline in citations, from 9% on August 31 to 2.7% on September 30.
Some analysts speculate that Reddit may be seeking a more favorable AI content deal with Google, and OpenAI’s reduced reliance could be a response to such negotiations or a move to diversify its data sources.
OpenAI’s ChatGPT-4o is currently the most adopted AI model, accounting for 44.72% of AI model usage.
