Apple was the first publicly traded US company to close above US$3 trillion in market value.
Apple reached the closing milestone on June 30, 2023, after briefly touching that level during trading in January of the same year. A closing valuation is based on the share price at the end of the trading session, so it differs from an intraday record.
Investor enthusiasm focused on Apple’s large installed base, premium hardware, services revenue, and expectations surrounding new products. The company had already established a pattern of crossing major valuation thresholds before competitors.
Market-cap rankings can change quickly because they depend on share prices. Currency conversions, share buybacks, and stock splits can also affect comparisons, which is why historical claims should specify the date and measurement used.
