If you’re looking to invest in the booming artificial intelligence (AI) sector, you may want to steer clear of Palantir Technologies ([PLTR] 1.06%) and instead consider these two rising stars in the space. While Palantir has built an impressive AI-powered data analytics platform, its sky-high valuation makes it a risky bet at current levels. What this really means is that there are better opportunities to capitalize on the AI megatrend without overpaying.

Nvidia: Powering the AI Revolution

One stock that looks like a much safer AI play is Nvidia ([NVDA] 0.11%). As Reuters reports, the chipmaker is well-positioned to continue benefiting from surging demand for its powerful graphics processing units (GPUs) that are essential for training and running AI models. Nvidia’s forward price-to-earnings ratio of 24.5 is much more reasonable than Palantir’s astronomical 128x multiple.

The bigger picture here is that Nvidia’s Rubin platform, set to launch in the second half of 2026, could be a game-changer. Rubin will enable inference – the process of using trained AI models to make predictions – at a fraction of the cost of Nvidia’s current Blackwell GPUs. This could unlock new use cases and drive even greater adoption of Nvidia’s technology in the AI ecosystem.

AMD: Challenging Nvidia’s GPU Dominance

Another AI stock worth considering is Advanced Micro Devices ([AMD] 2.15%). While Nvidia has long dominated the GPU market, AMD is emerging as a credible challenger with its MI400 series of chips designed specifically for AI workloads. As TechRadar reports, these chips offer impressive performance and could help AMD capture more share in the rapidly growing AI hardware market.

The key advantage of investing in AMD over Palantir is the former’s more reasonable valuation. At a forward price-to-sales ratio of just 5.5x, AMD offers much more upside potential than Palantir’s frothy 42x multiple. And with the company’s strong track record of innovation, AMD could very well emerge as a long-term winner in the AI arms race.

So while Palantir may have a great product and a strong underlying business, the current valuation simply doesn’t justify the risk. Investors would be better off focusing on Nvidia and AMD – two AI stocks that offer better value and promising growth prospects.
