【三家公司5.2兆美元,超過45年科技股上市總和】🏷️
SpaceX、Anthropic 與 OpenAI 三家公司的估值合計約 5.2 兆美元,比 1980 到 2025 年之間 3,365 家美國科技公司掛牌時的市值總和 4.1 兆美元還要多。
這個對比之所以看起來驚人,是因為它比的是起跑線。4.1 兆是那 3,365 家公司上市第一天的市值,不是它們後來長成的樣子。微軟 1986 年掛牌當天市值 7.77 億美元,亞馬遜 1997 年是 4.38 億美元,兩家今天的規模都是當年的幾千倍,而這些後來的成長完全沒有被算進 4.1 兆裡面。
還有兩件事值得一起記住。歷史數字沒有做通膨調整,1980 年代的一美元和現在的一美元被直接相加。而 5.2 兆這一邊,Anthropic 用的是市場預期它掛牌時的價格,OpenAI 用的是私募市場正在談的估值,兩者都還沒有經過公開市場成交。

Three Companies Worth More Than 45 Years of Tech Listings
SpaceX, Anthropic and OpenAI are together valued at about $5.2 trillion, more than the $4.1 trillion combined market value of all 3,365 US technology companies that went public between 1980 and 2025.
The comparison looks startling because it measures starting lines. That $4.1 trillion is what those 3,365 companies were worth on their first day of trading, not what they grew into. Microsoft was worth $777 million the day it listed in 1986 and Amazon $438 million in 1997. Both are thousands of times bigger today, and none of that later growth is inside the $4.1 trillion.
Two other things belong in the picture. The historical figure is not adjusted for inflation, so a 1980s dollar is being added straight to a 2026 dollar. And on the $5.2 trillion side, Anthropic is counted at the valuation investors expect when it lists and OpenAI at the private valuation currently under discussion. Neither has cleared a public market yet.
