US‑China AI Duopoly Pushes Europe to Build Sovereign Stack

TL;DR: The United States and China dominate frontier AI models, leaving Europe dependent on foreign systems for public‑sector decisions. A new Mistral‑SAP partnership aims to build a sovereign European AI stack, but success will require united investment and the inclusion of smaller states like Malta.

Context Digital sovereignty used to mean where data lives and which laws apply. Now it also covers how information is created, interpreted, and acted on by artificial intelligence. When a public officer uses an AI tool to draft a permit or assess a tax, the model’s training shapes the recommendation. That training happens outside Europe for most leading models, so the state cannot fully inspect or control the logic behind the decision. The shift makes AI a layer of power that is harder to see than traditional infrastructure.

Key Facts The leading AI models are developed and operated in the United States, while a competitive Chinese ecosystem exists, led by DeepSeek. The Mistral‑SAP partnership announced at the November 2025 Berlin summit is the most significant institutional commitment to build a sovereign European AI stack. European leaders say Europe must unite, invest, and include Malta in building European AI capability. The partnership combines Mistral’s model expertise with SAP’s enterprise reach to create a full‑stack alternative.

What It Means Reliance on non‑European AI exposes public administrations to hidden biases and limits democratic oversight. Closing the gap to the US and Chinese frontier requires coordinated funding, shared infrastructure, and a pace the Union has not historically maintained. Including Malta and other smaller states can broaden talent pools and provide testbeds for sovereign models. Without rapid progress, European agencies will continue to outsource core interpretive functions to foreign jurisdictions. The effort also raises questions about data governance, model auditing, and cross‑border trust.

Watch for EU budget allocations in 2026 and pilot deployments in Malta to see whether the sovereign stack moves from commitment to operational use.
