President Donald Trump did one thing no sitting president has publicly carried out — he appeared to endorse a publicly traded firm by its inventory ticker image, praising protection tech agency Palantir Applied sciences (NASDAQ:PLTR) on Fact Social on Friday in a put up that reversed the inventory’s slide inside minutes.
“Palantir Applied sciences (PLTR) has confirmed to have nice conflict combating capabilities and gear. Simply ask our enemies!!! President DJT,” Trump wrote (1).
The put up got here on the finish of a brutal week for the inventory. Palantir shares had fallen 14–16% over the prior 5 days and have been down as a lot as 6% on Friday alone earlier than Trump’s endorsement hit. Inside minutes, the share worth ticked up roughly 3% from round $123 (2). Shares nonetheless closed decrease on the day at $128.06.
Sen. Mark Warner (D-Virginia) was among the many first to flag the put up, asking on X: “Is that this one other blatant instance of Trump manipulating markets?” (3). Warner’s put up included a screenshot of Trump’s Fact Social message.
The selloff had much less to do with Trump than with Anthropic — and a broader rout throughout the software program sector.
On April 7, Anthropic launched Claude Mythos Preview, a frontier AI mannequin constructed for its Venture Glasswing cybersecurity initiative. The mannequin was not made typically out there — Anthropic shared it with roughly 52 organizations — however the launch spooked traders who had been pricing enterprise software program corporations like Palantir as AI beneficiaries resistant to disruption (4). Individually, Anthropic’s annual recurring income had surged from $9 billion on the finish of 2025 to $30 billion by early April (5), elevating pressing questions on whether or not Palantir’s premium valuation might maintain.
The Pentagon blacklisted Anthropic in March after the AI lab refused to elevate security guardrails on its Claude fashions for autonomous weapons and mass surveillance. That pressured Palantir to start eradicating Claude from its Maven Sensible Techniques platform — the spine of its army AI work — and rebuilding elements of its software program, in keeping with Reuters (6). The pressured rebuild uncovered how dependent Palantir’s protection enterprise had grow to be on a single AI supplier.
