An analyst predicts that Microsoft, Amazon, and Taiwan Semiconductor Manufacturing will all reach $4 trillion market valuations by 2028, expanding a club currently occupied only by Nvidia, Apple, and Alphabet.
Microsoft, valued at $3.6 trillion, could reach the milestone as soon as the end of 2026 if its price-to-earnings multiple normalizes from its current 24× to a prior level near 30×.
Amazon and Taiwan Semiconductor face different paths: Amazon needs its valuation multiple to rise from 21× to 30× forward earnings, which would generate the 44% growth required to cross $4 trillion, while Taiwan Semiconductor must grow revenue at roughly 28% annually—slightly below Wall Street's 43% and 34% forecasts for this year and next—to reach the target by 2028.
What happened
Three companies—Microsoft ($3.6 trillion), Amazon ($2.8 trillion), and Taiwan Semiconductor Manufacturing ($2.2 trillion)—are positioned to reach $4 trillion valuations by 2028, according to analyst Keithen Drury. Microsoft could reach that threshold by the end of 2026 if its valuation multiple rises to 30 times forward earnings, a move that would represent 23% growth.
Why it matters
Currently only Nvidia, Apple, and Alphabet have reached $4 trillion valuations. Microsoft and Amazon are trading well below their historical valuation multiples (Microsoft at 24× forward earnings vs. its prior 30s range; Amazon at 21× vs. its typical 30×), suggesting room for near-term re-rating without requiring dramatic earnings growth. For Taiwan Semiconductor, which trades at 25.5× forward earnings, the milestone depends on business growth; Wall Street expects 43% revenue growth for the remainder of this year and 34% next year—above the roughly 28% compound annual growth rate needed to reach $4 trillion by 2028.
What to watch
Microsoft could potentially reach $4 trillion by the end of 2026 if valuation multiples normalize. Amazon is likely to enter the club before 2026 ends or by 2027, as its stock historically does not remain undervalued long. Taiwan Semiconductor's timeline extends to the end of 2028, contingent on delivering the revenue growth Wall Street forecasts.

The $4 trillion valuation threshold has historically been a rare milestone—only Nvidia, Apple, and Alphabet currently hold it. This prediction suggests that milestone is about to become less exclusive, driven by a combination of valuation normalization and fundamental growth. Microsoft and Amazon represent the most immediate candidates, not because their underlying businesses have fundamentally changed, but because their price-to-earnings multiples have compressed to historically low levels. Microsoft trading at 24× forward earnings compared to its prior 30s range, and Amazon at 21× versus its typical 30×, create what the analyst frames as an opportunity for multiple expansion—a reversion to historical norms rather than exceptional growth. For investors, this implies that the three companies are relatively inexpensive by their own historical standards, which typically supports stock price recovery over time. Taiwan Semiconductor presents a different narrative: its current 25.5× forward earnings multiple is not unusually cheap, so reaching $4 trillion depends on actual business growth. Wall Street consensus—forecasting 43% revenue growth for the current year and 34% for next year—aligns with the roughly 28% compound annual growth rate required to cross the $4 trillion threshold by 2028, giving Taiwan Semiconductor a path grounded in operational execution rather than sentiment-driven valuation shifts.
