OpenAI’s ChatGPT Search, a feature that integrates real-time web information into ChatGPT’s responses, has seen a significant surge in European usage. According to a recent report from OpenAI Ireland Limited, the average monthly active users in Europe reached approximately 41.3 million for the six-month period ending March 31, 2025. This marks a substantial increase from the 11.2 million average monthly active users reported in the previous six-month period ending October 31, 2024.
This growth trajectory suggests that ChatGPT Search is on the verge of being classified as a very large online platform under the European Union’s Digital Services Act (DSA). The DSA imposes specific obligations on platforms exceeding 45 million average monthly users, including providing users with options to opt out of recommendation systems, sharing certain data with researchers and authorities, and undergoing external audits. Non-compliance with these regulations can result in fines up to 6% of a company’s global turnover, and persistent violations may lead to temporary suspension within the EU.
The rapid adoption of ChatGPT Search in Europe reflects a broader trend of increasing reliance on AI-driven tools for information retrieval. Since its launch, ChatGPT has evolved from a novel AI chatbot to a multifaceted platform offering real-time, web-based information. This evolution has been marked by significant milestones, including reaching 100 million monthly active users within two months of its November 2022 debut and achieving 400 million weekly active users by February 2025.
Several factors have contributed to this accelerated growth. The introduction of advanced models like GPT-4o and features such as Advanced Voice Mode have enhanced user engagement. Additionally, the expansion of ChatGPT Search to all users, both free and premium, has broadened its accessibility and appeal.
Europe’s leading role in the adoption of AI chat applications is noteworthy. Research indicates that European developers have been at the forefront of creating AI chat apps, with the continent accounting for 34% of the global market in this sector. Countries like Turkey have emerged as significant players, contributing substantially to the app download figures.
OpenAI’s strategic expansion into Europe underscores its commitment to the region. The establishment of an office in Dublin, Ireland, aims to strengthen operations, trust and safety measures, and legal frameworks to better serve the European market. This move aligns with OpenAI’s proactive approach to navigating the complex regulatory landscape of the EU, particularly in anticipation of the forthcoming EU AI Act, which seeks to regulate AI applications based on their perceived risks.
Despite the impressive growth, challenges remain. Studies have highlighted instances where AI-powered search tools like ChatGPT Search have provided inaccurate information. Ensuring the reliability and accuracy of AI-generated content is paramount, especially as these tools become more integrated into daily information-seeking behaviors.
In conclusion, the rapid growth of ChatGPT Search in Europe signifies a transformative shift in how users access and interact with information online. As OpenAI continues to expand its presence and refine its offerings, it will be essential to balance innovation with compliance and accuracy to maintain user trust and meet regulatory standards.
