## Summary

The 15th edition of the BigData & AI Paris trade show, with around 15,000 visitors expected, took place on 15 and 16 September 2026, with agentic AI as the dominant theme. Mistral AI presented its three-year, €100 million partnership with TotalÉnergies, aimed at customising an AI model using the group's proprietary data. According to Guillaume Bour, VP Revenue Europe South at Mistral AI, 9 out of 10 POCs fail to scale up, for technical reasons, as well as change management and operational integration issues. He cites the reporting line of the AI project, whether to the Comex or lower down, as an indicator of its chances of success. The show's director, Emilie Pierre-Desmonde, built the programme around sovereignty, broken down into infrastructure, architecture and business, while some visitors regret that the case studies still feel too marketed.
