Summary
- Mistral secures $830 million in debt to expand AI infrastructure in Europe
- DeepSeek chatbot faces its longest outage since its 2025 surge
- Developments highlight both growth and reliability challenges in the global AI race
STOCKHOLM/BEIJING, March 30, 2026 — Europe’s push to scale artificial intelligence infrastructure gathered pace as Mistral raised $830 million in debt to fund a major data centre expansion, even as reliability concerns surfaced in Asia following a prolonged outage at DeepSeek’s chatbot platform.
Mistral said the funding will be used to acquire 13,800 AI chips from Nvidia for a new data centre near Paris. The facility, located in Bruyères-le-Châtel, is expected to become operational in the second quarter of 2026.
The debt financing — Mistral’s first — was backed by a consortium of seven banks, including BNP Paribas, Crédit Agricole CIB, HSBC and MUFG, underscoring growing investor confidence in Europe’s AI ecosystem.
The Paris-based startup has positioned itself as a regional alternative to major U.S. technology companies such as Microsoft, Google and Amazon, offering AI models and infrastructure services to governments and enterprises seeking greater technological autonomy.
Chief executive Arthur Mensch said expanding infrastructure within Europe is essential to support customers and sustain innovation capacity in the region. The company is also planning a second data centre in Sweden and aims to secure 200 megawatts of capacity across Europe by 2027.
At the same time, the global AI sector received a reminder of operational vulnerabilities. DeepSeek’s chatbot platform experienced a “major outage” lasting 7 hours and 13 minutes on Monday, marking its longest disruption since its rapid rise in early 2025.
According to the company’s status updates, the outage began in the early hours of the day and was resolved by 10:33 a.m. local time. No cause was disclosed, in line with company protocol, although such incidents can stem from server failures or software-related issues.
The disruption affected both general users and developers relying on DeepSeek’s API services, whereas previous outages had largely been limited to backend systems.
DeepSeek’s chatbot, powered by its R1 and V3 models, gained widespread attention last year and continues to be closely monitored by the industry, particularly as expectations build around its next-generation model. The company has not provided a timeline for its release.
Why this matters
- Highlights accelerating investment in AI infrastructure as regions compete for technological leadership
- Reinforces Europe’s push to reduce reliance on U.S.-based cloud and AI providers
- Underscores operational risks as AI systems scale globally
- Reflects rising demand for both computing power and service reliability
