Palantir's Rule of 40 Surge Signals Strong AI-Driven Performance

Palantir Technologies (PLTR) has posted a dramatic improvement in its Rule of 40 metric, surging from 64% in Q2 2024 to 155% in Q2 2026, according to Zacks Investment Research. The acceleration stems from revenue growth climbing from 27% to 93% over the period, while adjusted operating margins expanded from 37% to 62%.

The dual expansion of growth and profitability marks PLTR as a rare high-quality performer in enterprise software, with AI demand driving the top-line surge. However, the gains come with a valuation premium: PLTR trades at 42.97X forward price-to-sales, more than ten times the industry average of 3.97X.

The Rule of 40—which adds revenue growth rate to operating margin—is a key benchmark for software companies, with scores above 40% considered strong. PLTR's 155% reading places it in elite territory but raises questions about sustainability at current multiples.
