Nvidia and Palantir Approach Record Highs: Too Late to Buy?

Nvidia and Palantir continue to lead the AI-driven bull market, with Nvidia recently announcing a landmark $100 billion partnership with OpenAI to deploy 10 gigawatts of AI infrastructure, which has prompted a technical breakout. Both companies, having surged over 1,300% and 2,300% respectively in three years, continue to press toward new record highs, underpinned by strong thematic tailwinds in AI. While their central roles in the AI era suggest further upside for long-term investors and traders, current high valuations underscore the importance of disciplined risk management and timing.

Analysis

Nvidia (NVDA) and Palantir (PLTR) are solidifying their positions as market leaders, both approaching record highs driven by powerful secular trends in artificial intelligence. Over the last three years, Palantir has surged over 2,300% while Nvidia has climbed over 1,300%, with momentum continuing through the first nine months of 2025. A significant catalyst for Nvidia is the newly announced partnership with OpenAI, which involves a progressive investment of up to $100 billion to deploy 10 gigawatts of Nvidia systems for next-generation AI infrastructure, with the first deployment in H2 2026. This news has propelled NVDA's stock out of a technical consolidation into new record territory, with the $180 level cited as a key support for a continued bull run. Palantir is framed as the quintessential thematic AI play, benefiting from a convergence of AI adoption, geopolitical tensions, and increased defense spending, with its chart suggesting a continued climb toward new highs. While the long-term outlook for both companies remains strong due to their entrenched leadership in AI hardware and applied AI solutions, their parabolic gains have resulted in high valuations that leave little margin for error, presenting a timing challenge for new investment.

Key Decisions for Investors

• Given the strong secular tailwinds and leadership positions, long-term investors should consider maintaining exposure to NVDA and PLTR, as they remain central to the ongoing AI theme.
• Tactical traders may find opportunities in the current momentum, particularly NVDA's technical breakout post-OpenAI news, but must utilize disciplined risk management and defined exit levels due to heightened volatility and valuation risk.
• Due to the significant run-up and elevated valuations, investors should prioritize careful position sizing and risk management, as chasing these breakouts increases exposure to sharp corrections despite the positive fundamental narrative.
