Summary Yes, under the proposed Cloud and AI Development Act (CADA), a project designated as a "frontier AI priority project" must be cross-border. Article 8(b) explicitly mandates that such a project "involves the participation of at least three Member States." This is not a suggestion but a cumulative eligibility criterion. The proposal is designed to address the "unprecedented scale of resources" required for frontier AI by forcing Union-level collaboration and resource pooling, thereby excluding purely national initiatives from this specific designation and its associated Union-matched computing benefits.

Detail

The Cloud and AI Development Act (CADA), as proposed in COM(2026) 502 final, establishes a targeted mechanism to accelerate the development of "frontier AI." Defined in Article 2(4) as AI models or systems that "approach, reach or exceed the current state of the art," frontier AI is recognized as a strategic asset requiring massive investment. To ensure these projects serve the Union's collective interests rather than fragmented national agendas, the proposal imposes a strict multi-state requirement.

The Mandatory Cross-Border Threshold: Article 8(b)

The core of the cross-border requirement is found in Article 8, titled "Criteria for frontier AI priority projects." This article sets out the conditions under which the Commission may, by decision, recognize a project as a priority. The criteria are cumulative; failure to meet any one of them disqualifies the project.

Article 8(b) states that the project must be:

"undertaken by a European digital infrastructure consortium established pursuant Decision (EU) 2022/2481 or another legal entity eligible for funding under Union law and it involves the participation of at least three Member States."

This provision creates a hard floor for geographic diversity. A project led by a single Member State, even if it involves multiple companies or research institutes within that state, cannot be recognized as a frontier AI priority project. The involvement of "at least three Member States" ensures that the project has a genuine European dimension, fostering integration and reducing the risk of market fragmentation.

The legal structure requirement in Article 8(b) further reinforces this. The project must be undertaken by:

  1. A European digital infrastructure consortium (EDIC) established under Decision (EU) 2022/2481; or
  2. Another legal entity eligible for funding under Union law.

This ensures that the cross-border collaboration is formalized through governance structures capable of managing Union funds and accountability, rather than relying on informal or ad-hoc agreements.

Rationale: Union-Level Collaboration and Resource Pooling

The insistence on a multi-state requirement is not arbitrary; it is driven by the specific economic and strategic challenges of frontier AI development. Recital 34 of the proposal provides the legislative context, noting that "given the unprecedented scale of resources required for frontier AI development," these projects "require a collaborative approach at Union level."

The recital highlights two key factors necessitating this approach:

  1. Technical Complexity and Capital Intensity: Frontier AI projects are described as having a "technical complexity and capital-intensive nature" that exceeds the capacity of individual Member States to support effectively on their own.
  2. Resource Pooling: To make these projects viable, the proposal mandates that participating Member States "pool computing time and other relevant resources to support the implementation of the designated project" (Article 8(c)).

This pooling mechanism is inherently cross-border. It relies on the contribution of resources from multiple jurisdictions to create a critical mass of computing power and expertise. By requiring at least three Member States, the proposal ensures that:

  • Risk is Distributed: The high financial and technical risks are shared across multiple public budgets.
  • Sovereignty is Strengthened: The Union avoids reliance on single-national champions that may lack global scale, instead building a collective European capability.
  • Benefits are Shared: The resulting technologies and infrastructure are designed to serve the wider Union, preventing the "hoarding" of strategic assets by a single Member State.

Contrast with National-Only Projects

It is crucial to distinguish between "frontier AI priority projects" under CADA and other national AI initiatives. The proposal does not ban national AI projects. Article 7 requires Member States to adopt "national cloud and AI strategies," which can include domestic support for AI development.

However, a project that is strictly national (involving only one Member State) cannot be designated as a "frontier AI priority project" under CADA. This distinction has significant practical consequences regarding access to Union resources.

Under Article 9, titled "Computing support for AI projects," the Union and Member States are obligated to allocate sufficient AI computing resources to support designated frontier AI priority projects. Specifically, Article 9(2) states:

"The Union shall at least match the AI computing resources contributed by Member States to frontier AI priority projects to the extent that sufficient AI computing capacity is available within the Union's share of European high performance computing access time."

If a project is national-only, it fails the Article 8(b) criterion and cannot be designated. Consequently, it cannot trigger the Union's matching obligation under Article 9(2). While a Member State may still fund a national project using its own budget, it cannot leverage the additional, matched computing time from the Union's EuroHPC capacity that is reserved exclusively for cross-border priority projects. This creates a powerful financial and strategic incentive for national actors to seek cross-border partners to reach the three-Member-State threshold.

The "Grand Challenge" Context

The cross-border requirement also aligns with the broader "Grand Challenges" outlined in Annex I of the proposal. Grand Challenge 3 focuses on "Frontier AI," aiming to develop "next generation of multimodal frontier AI models and systems." The proposal envisions these challenges as "large-scale, cross-sectoral initiatives" (Article 6(2)) that address "major technological and industrial challenges of strategic relevance for the Union."

The multi-state requirement ensures that these initiatives are truly Union-wide, leveraging the diverse strengths of different Member States to tackle challenges that no single country could solve alone. This approach is consistent with the proposal's general objective to "improve the functioning of the single market" and increase "strategic autonomy" (Article 1(3)).

What this means for you

For legal counsel, compliance officers, and project managers in technology firms, research institutions, or public bodies, the cross-border requirement has immediate strategic implications:

  1. Consortium Building is Mandatory: If your organization aims to access Union-matched AI computing resources via the frontier AI priority project mechanism, you must form a consortium that includes partners from at least two other Member States. A domestic-only consortium is ineligible.
  2. Legal Structure Verification: Ensure your project is undertaken by an EDIC (under Decision (EU) 2022/2481) or another entity explicitly eligible for Union funding. Verify that the statutes of your legal entity allow for the pooling of resources across borders as required by Article 8(c).
  3. Resource Pooling Documentation: Your application must demonstrate concrete commitments from the participating Member States to pool computing time and resources. Vague intentions are insufficient; the Article 8(c) requirement for "pooling" must be substantiated by binding agreements or formal commitments.
  4. Strategic Pivot for National Projects: If your project is strictly national, do not attempt to apply for the "frontier AI priority project" designation. Instead, focus on national funding streams and ensure your project aligns with your Member State's national cloud and AI strategy (Article 7). Recognize that you will not have access to the Union-matched EuroHPC capacity reserved for cross-border projects.
  5. Timing and Eligibility: The criteria in Article 8 must be met at the time of the application. You cannot apply first and "find partners later." The participation of the three Member States must be documented and verified during the selection process.

Common misconceptions

Misconception 1: "We just need partners from other countries, not necessarily Member States." Correction: Article 8(b) specifically requires the participation of "at least three Member States." Partnerships with entities from third countries (non-EU) or even other European countries that are not EU Member States do not satisfy this criterion. The focus is strictly on strengthening the internal market and Union sovereignty.

Misconception 2: "We can apply first and find partners later." Correction: The criteria in Article 8 are cumulative and must be fulfilled at the time of application and selection. The Commission will not designate a project that lacks the required multi-state participation. The "participation" must be substantive, documented, and legally binding in the application.

Misconception 3: "National projects are banned under CADA." Correction: National AI projects are not banned. They are simply excluded from the specific "frontier AI priority project" designation and its associated Union-matched compute benefits. Member States are encouraged to support national AI development through their national strategies (Article 7), but these remain distinct from the cross-border priority projects designed for Union-level strategic assets.

Misconception 4: "Two Member States are enough if the project is large." Correction: The threshold is absolute. Article 8(b) requires "at least three Member States." A project involving only two Member States, regardless of its size or technical merit, does not meet the statutory definition of a frontier AI priority project.
