In proportion
All public purchasing in Spain — general government spending on goods, services and investment, the measure the OECD and the European Commission use for public procurement — came to €192 billion in 2025, 11.3% of GDP (Eurostat). Award notices on TED cover only the contracts above the EU thresholds, so they show who wins, not the whole of that spending.

Values are the awarded amounts published in the notice (framework ceilings and estimates are never added), converted to euro at the ECB yearly average. Company size is the SME flag of the notice (eForms BT-165). Read the methodology.
