October 2026. Among Qonto's business customers across France, Germany, Spain, and Italy, Claude is now ahead of ChatGPT overall. According to the Qonto AI Adoption Index, as of September 2026, 10.9% had at least one Claude subscription, versus 10.0% for ChatGPT. In total, 16.7% paid for at least one AI tool. Claude overtook ChatGPT in June 2026 and has extended its lead since, led mainly by France and Germany.
The picture varies by market:
- Claude leads clearly in France (10.2% vs 9.3%) and Germany (14.9% vs 13.3%), which also has the highest overall adoption of the four markets, at 21.9%.
- Spain is close to even (14.5% vs 14.8%), after Claude briefly led between June and August.
- Italy is the exception, with ChatGPT remaining ahead (8.9% vs 7.5%), and overall adoption the lowest of the four markets, at 13.0%. Even in Professional & Digital Services, the sector with the highest AI adoption across all four markets, Italy's businesses still favor ChatGPT (15.0% vs 14.8%), while in France and Germany that same sector shows Claude's widest lead.
