Palantir Rises 5% on Knox Partnership for Federal Cloud Software; Leidos Edges Higher, Booz Allen Hamilton Slips

A new federal cloud alliance is putting Palantir Technologies (NASDAQ:PLTR | PLTR Price Prediction) well ahead of the government contractors it competes with for agency software work. Palantir stock is up 5% to $195.36 in early trade, a rebound fueled by a new partnership with Knox Systems.

Meanwhile, Leidos (NYSE:LDOS) stock is up 1% to $126.38, a gain that trails the advance in Palantir shares by a wide margin. Booz Allen Hamilton (NYSE:BAH) shares are down 1% to $73.41, moving in the opposite direction from Palantir stock.

Two funds help show how specific the rally in Palantir shares is. The SPDR S&P 500 ETF Trust (NYSEARCA:SPY) is up 0.8%, so the broad market is stronger as well. However, the iShares U.S. Aerospace & Defense ETF (CBOE:ITA) is down 0.3%, leaving Palantir stock ahead of both funds and of Leidos and Booz Allen Hamilton shares, a gap that ties the move to the Knox partnership.

Knox Partnership Opens a Faster Federal Cloud Path

Palantir and privately held Knox Systems announced the deal, aiming it at customers working in Federal Risk and Authorization Management Program (FedRAMP) and high-security Department of War cloud environments. Knox runs a large managed federal cloud and offers an accelerated path to FedRAMP authorization. On the other side of the deal, Palantir has helped software companies deploy to the federal government on its own accredited infrastructure.

Kevin Kawasaki, Palantir’s global head of business development, stated, “The mission can’t wait for technology to catch up.” Combining Knox’s authorization path with Palantir’s accredited infrastructure is designed to shorten the road for commercial software makers trying to reach defense customers.

Federal Revenue Momentum Gives the Deal Weight

In Q2 2026, Palantir’s U.S. Government revenue rose 90% year over year to $809 million, while total revenue grew 92.8% to $1.94 billion. Chief Executive Alex Karp tied that growth to sovereign AI, declaring in the Q2 earnings release, “Demand for AI sovereignty has now been unleashed.”

Gotham for federal work, Foundry for business clients and the Artificial Intelligence Platform (AIP) ground the data and AI software Palantir sells to government and commercial customers. Leidos and Booz Allen Hamilton run a different model, earning most of their revenue from government services and IT contracts.

Palantir’s U.S. Commercial revenue grew 149% year over year to $764 million in Q2. Palantir’s total contract value reached $3.37 billion.

AI Valuation Debate Hangs Over the Rebound

The advance in Palantir shares comes after the stock fell sharply in the prior session during a broad technology selloff. Shares of Palantir trade at a P/E ratio of 263x, a premium multiple that magnifies reactions to federal contract news (we also pulled together seven companies driving the AI expansion beyond the chipmakers in a free report here).

Risk factors in Palantir’s Q2 materials include long and unpredictable sales cycles and customer contracts subject to termination-for-convenience provisions. Its reliance on stock-based compensation, which reached $265 million in Q2, adds another point of contention for Palantir shareholders. The company also flags revenue concentration in the U.S. market, which ties its fortunes closely to domestic federal and commercial spending.

Knox Adoption Becomes Palantir’s Next Proof Point

Now investors can watch for whether Knox brings more software makers onto Palantir’s federal infrastructure. Federal growth backs bulls and the premium valuation backs bears, so caution fits: investors may keep their positions modestly sized.

Palantir’s management expects Q3 2026 revenue of $2.16 billion to $2.164 billion. Palantir’s next quarterly report could show whether federal momentum holds after the Knox announcement.
