Spain formalises €752M investment in Diamond Foundry for chip manufacturing
What's the deal? The Spanish government has formalised a €752M investment in Diamond Foundry, a US tech company, to manufacture chips in Spain. The deal brings advanced semiconductor production to the country, marking a significant bet on homegrown chip capacity.
Why now? Europe is racing to reduce its dependence on Asian semiconductor supply chains. The EU Chips Act, which aims to double the bloc's share of global chip production to 20% by 2030, has created a policy window for member states to attract major fabrication projects. Spain is positioning itself as a destination for chipmakers looking to set up shop on the continent.
What could go wrong? Semiconductor fabs are notoriously expensive and complex to build. Delays, cost overruns, and shifting market demand have tripped up chip projects elsewhere in Europe and the US. Diamond Foundry, known primarily for lab-grown diamonds used as semiconductor substrates, would need to scale manufacturing capabilities significantly — and Spain would need to develop the skilled workforce to support it.
The signal: Diamond Foundry, classified as a late-growth stage company that built its reputation culturing diamonds with a zero-carbon footprint in California, is making a significant pivot toward semiconductor substrates — and European governments are willing to back that bet with public capital. Spain's €752 million commitment underscores how fiercely EU member states are competing to anchor advanced chip manufacturing on their soil, even when it means bankrolling a company still scaling into the sector.
