The economic size of tech giants and multinationals has grown rapidly in recent years. Nvidia hit a $5.7 trillion market capitalisation in mid-May. The company now exceeds the entire economy of Germany — the world’s third largest and Europe’s biggest — which stands at $5.45 trillion in gross domestic product (GDP).
So, how do the market capitalisations of tech giants and multinationals compare to the world’s largest economies? And where does Europe stand?
Nvidia, the US-based semiconductor firm whose chips power everything from video games to AI systems, is the world’s most valuable company. After becoming the first company to pass $5 trillion (€4.38tn) in market capitalisation in October 2025, its value reached $5.7 trillion (€4.89tn) in mid-May 2026.
Having already surpassed Japan and the UK in economic size, it now overtakes Germany’s projected 2026 GDP as well, according to the IMF. Market capitalisation data is sourced from CompaniesMarketCap as of 14 May 2026.
The IMF predicts that Germany’s 2026 GDP would be $5.45 trillion (€4.67tn). The US remains the world’s largest economy at $32.38tn (€27.75tn), followed by China at $20.58tn (€17.87tn).
As Germany is Europe’s largest economy, Nvidia’s market cap surpassing it means the company is now larger than every European economy, including the UK $4.26tn (€3.65tn), France $3.6tn (€3.08tn), Italy $2.74tn (€2.35tn) and Spain $2.09tn (€1.79tn).
Nvidia exceeds the combined GDP of 19 EU countries
Alphabet (€4.12tn) and Apple (€3.75tn) are also larger than every European economy except Germany. France (€3.08tn) surpasses Microsoft (€2.61tn) and Amazon (€2.46tn) in economic size. However, both companies still exceed Italy’s GDP (€2.35tn), the continent’s fourth largest economy.
The combined GDP of the 19 smallest EU economies totals $5.02tn (€4.3tn), still short of Nvidia’s $5.7tn (€4.88tn) market capitalisation.
Nvidia CEO Jensen Huang joined Donald Trump’s high-profile visit to China this week. In March, Huang said surging demand for artificial intelligence could drive Nvidia’s sales towards $1tn within two years.
Top 5 US companies vs Europe’s five largest economies
The combined market capitalisation of the five largest US companies — Nvidia, Alphabet, Apple, Microsoft and Amazon — stands at $20.81tn (€17.84tn). That exceeds the total GDP of Europe’s five largest economies — Germany, the UK, France, Italy and Spain — which amounts to $18.14tn (€15.55tn).
No European company comes close to US tech giants
Dutch chipmaker ASML is the highest-ranked European company on the list, appearing at 21st with a market capitalisation of $610.69bn (€523.66bn). Europe has no company of comparable scale to the US tech giants.
Swiss pharmaceutical giant Roche has a market capitalisation of $335.1bn (€287.44bn), while UK-based AstraZeneca stands at $286.84bn (€246bn).
Market capitalisation and GDP measure different things. GDP reflects the total value of goods and services produced by an economy in a year, while market capitalisation represents the market value of a company’s equity and reflects investors’ expectations about its future earnings and growth prospects.
Still, the comparison offers a striking illustration of the scale these companies have reached.
