The expansion of Pax Silica into Europe this week reshapes the global AI supply chain map, and the effects will ripple through industries far beyond the semiconductor fabs and rare-earth processing plants. The US-led initiative, now including Germany, Greece, and the Netherlands alongside a raft of other nations from Argentina to Kazakhstan, is purpose-built to manage an AI economy that is “revolutionising the shape of the global economy,” according to its architect Jacob Helberg. But the real story lies in what this means for the countries left outside the confederation.
China’s dominance over rare earths and other critical supply-chain components has long been a lever of political influence. The Pax Silica response is blunt: build a parallel system.
The grouping’s expansion into Europe suggests the US administration believes the G7 and G20 are not fit for the task. Those forums, designed for an earlier era of trade and diplomacy, cannot move fast enough to secure the materials and manufacturing capacity that AI demands. Helberg called Pax Silica “not a treaty among the few, but a confederation of the capable.” The capable, in this framing, are the makers, the shippers, and the builders of this century’s foundations.
For the new European members, the consequences are immediate and concrete. Germany, Greece, and the Netherlands now sit at a table where supply-chain security is the primary currency.
They gain access to a framework that Helberg says will “shape” an American alternative to initiatives like the UN Global Digital Compact, which he has criticised. That compact, backed by many developing nations, pursues a different vision of digital governance. Pax Silica’s members are opting out of that vision in favor of a leaner, more targeted arrangement.
The trade-off is clear: deeper integration with US-led technology policy, and a sharper break from Chinese supply chains. The timing matters. AI is not a future concern; it is reshaping global trade and production right now.
The initiative’s expansion this week, with Argentina, Chile, Costa Rica, Kazakhstan, and Panama also set to join, signals that the US is building a network that spans the Americas, Central Asia, and now Europe. These are not the usual suspects.
Kazakhstan, sitting on significant rare-earth deposits, becomes a player in a game that was previously dominated by China. Argentina and Chile, rich in lithium essential for batteries and AI hardware, gain a direct line into a governance structure that prioritises their resources. For the countries not invited, the fallout is starker.
The Pax Silica members are likely to coordinate investment, technology sharing, and export controls among themselves. Non-members face the prospect of being locked out of critical supply chains or forced to accept terms set by the confederation.
Helberg’s language of “makers” and “shippers” draws a line between those who build the AI economy and those who merely use it. That distinction will have real economic weight. The European expansion also shifts the political calculus within the EU.
Germany and the Netherlands are industrial powerhouses with deep ties to both US and Chinese markets. Greece, a smaller economy, brings a strategic maritime position. Their joint membership suggests a coordinated European move, but one that bypasses the EU’s own cumbersome decision-making machinery.
The bloc has struggled to forge a unified AI policy. Pax Silica offers a faster route, but one that ties European supply chains more tightly to American strategy.
What happens next is uncertain but consequential. The initiative’s members must now translate the confederation into concrete supply-chain projects. Rare-earth processing, chip fabrication, and data-center construction all require years of investment.
China will not cede its position quietly. The real test of Pax Silica will be whether it can deliver the hardware and materials that its members need, or whether it remains a diplomatic club with limited practical reach.
For now, the map has been redrawn. The capable have chosen their side.
