A trailing price-to-earnings ratio of 168 is the number investors in Palantir Technologies (NASDAQ: PLTR) must weigh before committing capital through the rest of the decade.
That stretched valuation stands in sharp contrast to RTX Corporation (NYSE: RTX), which reported Raytheon division sales of $8.3 billion in the second quarter of 2026, an 18% increase year over year.
Rising defense budgets across the globe have sharpened investor appetite for both companies, yet they represent fundamentally different bets on how modern militaries will spend their money.
RTX derives its strength from hardware that governments cannot easily substitute, including air and missile defense systems, precision weapons, radars, and naval equipment.
Those systems are not discretionary purchases that defense ministries can defer; they require continuous maintenance, replenishment, and capability upgrades to remain effective.
The U.S. and allied nations are actively rebuilding stockpiles depleted by recent conflicts, while simultaneously expanding production capacity and upgrading aging platforms, all areas where RTX holds established positions.
Raytheon’s second-quarter growth was broad-based, with air and space defense, naval programs, and land and air defense systems all contributing to the revenue increase.
Palantir’s case rests on an entirely different foundation, one built on software that helps defense and intelligence agencies synthesize data from multiple sources to support battlefield decisions and operational coordination.
Its Artificial Intelligence Platform, known as AIP, allows government and commercial clients to deploy artificial intelligence against their own internal data and operational systems, a capability that has found rapid adoption as militaries lean harder on drones, satellite imagery, and real-time intelligence feeds.
The growth numbers Palantir posted in its most recent quarter are difficult to ignore, with total revenue rising 93% year over year, U.S. government revenue up 90%, and U.S. commercial revenue surging 149%.
Management responded to that momentum by raising full-year guidance, signaling confidence that AI adoption across both public and private sectors has further room to accelerate.
The core tension for investors is whether Palantir’s explosive growth justifies a valuation that leaves almost no room for execution stumbles, slower AI adoption, or competitive pressure from larger technology firms.
RTX, by contrast, benefits from a record order backlog and a valuation that reflects the steadier, if less dramatic, rhythm of long-cycle defense contracting rather than software hypergrowth.
Northrop Grumman occupies similar terrain to RTX, with both companies offering investors direct exposure to the hardware programs that form the backbone of allied defense infrastructure.
For investors prioritizing capital preservation alongside upside through 2030, the mission-critical, contract-backed revenue streams of established defense hardware makers present a lower-risk path through an undeniably strong spending cycle.
