Palantir is still trading at a premium multiple, leaving the shares highly sensitive to any shift in confidence around growth and competition.The move comes as the company’s business remains anchored by long-term government work, reinforced by the Pentagon’s decision to make Maven Smart System a program of record, while its commercial business is expected to drive future growth. Investors will be looking to see if Palantir can quickly win new commercial contracts to support the recovery, instead of relying mainly on defense deals and a stock price that already expects ongoing AI leadership.Read NextApr 13, 2026 •By Keithen DruryPalantir's AIP Is Its Secret Growth Weapon.
