AI’s High-Flying Stocks Confront Harsh Reality as Growth Slows and Valuations Stretch

Silicon Valley’s AI balloon is finally losing helium. After months of sky-high expectations, tech’s hottest names are finding that astronomical valuations require equally astronomical growth — a bar that’s getting harder to clear. NvidiaNVDA

just logged its narrowest earnings beat in nine quarters, while PalantirPLTR

still trades at 245x forward earnings, enough to make even seasoned bulls squirm.

• Nvidia posted 56% annual revenue growth — its slowest in two years — as “the law of large numbers dictates that the bigger you get, the more difficult it is to keep getting bigger.”
• Similarly, Palantir would need 50% yearly growth for five straight years at 50% margins just to match the P/E ratios of peers like MicrosoftMSFT
  and AMDAMD
  .

Valuation woes: The valuation gap has become so extreme that analysts are running out of creative ways to justify current prices. Morningstar analyst Mark Giarelli noted Palantir’s valuation “causes heartburn” and creates “a lot of room below the stock chart for it to reprice in a negative way.” Nvidia faces additional structural headwinds like power grid limitations that no amount of financial engineering can fix. With growth trajectories moderating and expectations sky-high, these tech titans may find gravity is an unforgiving force.
