Amazon.com Inc. shares rose again Tuesday, extending a record-setting run that has brought the e-commerce and cloud giant to the doorstep of a $3 trillion market capitalization.

MarketWatch reported the stock was up about 0.7% in afternoon trading at roughly $274, marking a fourth consecutive record close in progress. By MarketWatch’s calculations, the shares would need to gain about 1.7% to roughly $278.89 to lift Amazon’s market cap above $3 trillion.

The move underscores continued investor appetite for mega-cap technology leaders, with valuation milestones increasingly acting as psychological levels watched by traders and index investors. While a $3 trillion threshold does not change fundamentals, it can amplify attention from market participants tracking index weights, momentum and liquidity in the largest U.S. stocks.

Investors will be watching whether the rally holds into upcoming catalysts, including corporate results across the tech sector and broader macro data that can influence risk appetite and equity valuations.
