Better Artificial Intelligence (AI) Stock: Palantir vs. SoundHound AI

Palantir (PLTR) and SoundHound AI (SOUN), two AI stocks that saw extraordinary gains in 2024, exhibit distinct financial profiles and significant valuation challenges heading into 2025. Palantir, a larger and profitable company with a 20% profit margin, reported 30% Q3 revenue growth and is projected for 24% growth next year. In contrast, SoundHound AI, while unprofitable with an 87% negative margin, posted 89% Q3 revenue growth and is forecast for 96% in 2025, aiming for adjusted EBITDA profitability by year-end. Both companies trade at extremely high price-to-sales multiples (PLTR 75x, SOUN 92x), indicating that substantial future growth is already factored into their stock prices, making their current valuations difficult to justify without sustained, exceptional performance.

Analysis

Palantir Technologies (PLTR) and SoundHound AI (SOUN) represent two distinct profiles within the AI sector, both characterized by extreme valuations following substantial stock price appreciation in 2024. Palantir, the more mature entity, demonstrates proven profitability with a 20% profit margin on $725 million in Q3 revenue, which grew 30% year-over-year. However, its growth is projected to decelerate to 24% next year, raising questions about its ability to sustain its 75x price-to-sales multiple. In contrast, SoundHound AI is a hypergrowth, pre-profitability company, with Q3 revenue surging 89% to $25 million and a forecast for 96% growth next year. This growth comes at the cost of a significant -87% profit margin, though management targets adjusted EBITDA profitability by the end of 2025. The core challenge for investors is that both companies' valuations—with SOUN trading at 92x sales—have priced in several years of flawless execution, leaving minimal room for error and making them highly sensitive to any shifts in growth trajectory or market sentiment.

Key Decisions for Investors

• Given the extreme price-to-sales multiples of 75x for Palantir and 92x for SoundHound AI, investors should recognize that substantial future growth is already priced in, exposing both stocks to significant downside risk on any execution shortfalls.
• Investors in Palantir should closely monitor revenue growth to see if it can defy the forecasted deceleration to 24%, as a failure to maintain a high growth rate challenges the justification for its premium valuation.
• For SoundHound AI, the critical milestones are its progress toward its guided adjusted EBITDA profitability by year-end 2025 and its ability to sustain near-triple-digit revenue growth to begin justifying its market capitalization.
• Investors must weigh Palantir's established profitability against its slowing growth versus SoundHound AI's explosive growth potential weighed down by its current unprofitability and higher valuation risk.
