#7 Saudi Aramco

At #7 in our top 10 companies by market cap in 2026 stands the great exception to tech’s dominance: Saudi Arabian Oil Company, or Saudi Aramco. The state-controlled energy titan is one of the most profitable companies in human history, and the only non-American firm in the upper reaches of this list. Its valuation rises and falls with oil prices and Middle East geopolitics – and with crude pushing toward $100 a barrel in 2026, Aramco’s fortunes are very much back in the global conversation.
