Palantir's stock is suddenly tumbling after a big upswing to start 2025.
Why it matters: The data software giant had emerged as a self-proclaimed AI "juggernaut" that one analyst said "could be the Oracle and Microsoft of the next decade."
The big picture: The company's shares have gone into reverse for two reasons:
Investors appear skittish about reports that the Trump administration plans to hack away at Defense spending.
The company disclosed in a public filing that CEO Alex Karp can sell nearly 10 million shares over the next six months.
By the numbers: Palantir shares closed down 5.2% today, but they're still up 40% for the year (and more than 350% over the past 12 months).
