Palantir stock rose 5.01% to close at $195.35 on Monday, October 19, 2026, according to MoneyCheck, after Palantir and Knox Systems announced a partnership to get commercial software running faster for US federal customers; 24/7 Wall St also reported a gain of about 5%. The announcement reached the MoveSurge news feed at 07:32:23 ET, before the market opened. Palantir traded at $185.98 just before it and at $186.07 ten minutes later, a change of 0.05% in thin premarket trading, so almost all of the gain came after the opening bell.
Knox runs a managed cloud for federal and Department of War customers and says it can take software through FedRAMP, the government's security approval for cloud services, in 90 days or less. The partnership pairs Palantir's already-accredited infrastructure with Knox's managed cloud for customers working in FedRAMP and Impact Level 5 (IL5) environments, the Defense Department level for sensitive unclassified data. The companies did not disclose financial terms.
Palantir's dated catalysts in 2026
- August 3, 2026: second-quarter results. Revenue rose 93% to $1.935 billion and net income was $1.07 billion, or $0.41 a share. US commercial revenue grew 149% to $764 million and US government revenue grew 90% to $809 million. Palantir raised its full-year revenue guidance to $8.150 billion to $8.158 billion from $7.650 billion to $7.662 billion and guided third-quarter revenue to $2.160 billion to $2.164 billion.
- August 4, 2026: the stock rose 29.455% in the first full session after the report, against an earnings move of about 10.1% priced by options beforehand.
- September 1, 2026: the US Army awarded $192 million of production orders for TITAN, a mobile targeting ground station, of which $127 million went to Palantir and $65 million to Anduril.
- October 19, 2026: the Knox partnership, and the 5.01% gain to $195.35.
What the Knox deal adds
Government buyers can only run cloud software that has cleared FedRAMP and, for defense work, the right impact level, and that approval process can take a long time. Knox sells a shortcut for software makers, and Palantir is pairing its accredited platform with that service, so more commercial software can reach the same federal customers that make up a large part of Palantir's revenue. The deal adds no disclosed revenue. The stock's 5.01% gain on the day was much smaller than the 29.455% move after the August results.
