Palantir (PLTR) Drops Nearly 7%, Erasing About $25 Billion in a Day

Palantir spent the entire session in retreat, settling near $155.26 by the close, a loss of roughly 6.9% that ranks as a notably severe single-day move for a stock that does not give back ground easily.
The scale of the decline matters because of how richly valued the company already was heading into the session. A drop of this size strips approximately $25 billion from its market capitalization, which is a meaningful reset even for a name accustomed to outsized swings in either direction.

The selling was sharpest in the opening hour and the afternoon brought a brief stabilization but no meaningful recovery, with the stock unable to reclaim the $157 level for any sustained period.
For investors already in the position, the next several closes will be telling. A stock that opens sharply lower and fails to recover by the end of the session often carries that pressure into subsequent days, making the near-term price action worth monitoring closely.
