Pick a question. Watch where Europe holds -- and where the stack snaps.
Europe can build a sovereign workplace and cloud today -- and every AI and compute goal snaps at the same two rungs: the AI accelerator and the leading-edge fab. Click any box for the sourced detail.
This map shows where Europe holds. Its companion, Where the sovereign euro goes, follows the money instead: who receives European public funding for AI and compute, and which definition of sovereign it is measured against.
Green ring = a credible European option at that layer · red = no European answer · click any box for the sourced detail.
Build & break is the quickest way in: pick a goal and the map fades, then lights every European option it has at each layer the goal needs. A layer turns green when Europe can field at least one option, red when it has none. The soft goals -- a sovereign workplace, a sovereign cloud -- come up all green. The AI and compute goals snap red at the same two rungs every time: the AI accelerator and the leading-edge fab. That repeat is the whole argument. A lit ring marks a credible European option, not a packaged sovereign product you can buy off a shelf -- the map names the contenders at each layer, it doesn't crown a winner.
Full landscape shows every contender and every dependency across the eight layers. The score dots are a sovereignty read across ownership, jurisdiction, operations, supply chain, substitutability and exit -- a low score is not a disqualification, it tells you where the risk lives. The partnership overlay wires up the named deals between players, coloured by deal type (see the key). "European-owned" spans the EU plus EEA/EFTA, Switzerland and the UK by ownership and control -- but ownership and jurisdiction are different axes: a Swiss or UK firm (Proton, Arm) is European yet sits outside the EU legal perimeter, so it scores lower on jurisdiction even when the cap table is European. Each card's detail panel now carries a four-axis read -- capability, jurisdiction, operational control, substitutability -- the why underneath its tier, and the axis lens recolours the whole board by any one of those axes (see CONTRIBUTING.md for the rubric).
This is a public market map built from public material -- Commission and EuroHPC releases, company announcements and credible trade press, as of July 2026. Vendors are named as public contenders, not as participants in any confidential process. Tie each claim to a public source before publishing.
