OpenAI's ChatGPT Search has experienced a remarkable surge in monthly active users within the European Union, soaring from 11.2 million at the close of 2024 to 41.3 million by early 2025. This robust growth trajectory indicates that ChatGPT Search is poised to cross the 45 million user threshold, which would classify it as a "very large" platform under the EU's Digital Services Act (DSA). As such, the platform could face heightened regulatory scrutiny and potentially stringent penalties, including fines of up to 6% of its global turnover or even the suspension of operations for non-compliance. Despite these looming challenges, ChatGPT Search has secured a notable share in the search engine market since its inception. However, recent research has highlighted concerns regarding the reliability of its search results, notably a high error rate in article identification and challenges in accurately processing news content.
