America's largest energy companies by market are in oil and gas, with ExxonMobil being joined by Chevron, ConocoPhillips, and Schlumberger; British oil companies BP and Shell also have significant presence in the United States and trade on both the London Stock Exchange and New York Stock Exchange.

Some of America's largest semiconductor firms and chip companies are Broadcom, Intel, AMD, and Qualcomm. Many of the United States' largest firms by market cap are technology companies. These companies are dominated by the Big Five tech giants (Apple, Amazon, Google, Microsoft, and Meta), though numerous software firms also dominate the American technology industry.
