As 2026 approaches, investors are navigating a market shaped by moderating interest rates, persistent geopolitical risk, and an artificial intelligence boom that is evolving from hype into infrastructure.
To identify where long-term capital may be best positioned, we asked ChatGPT to construct a hypothetical $1,000 stock portfolio based on market conditions as of December 26, 2025, focusing on durability, pricing power, and exposure to structural growth trends.
Rather than chasing speculative momentum, OpenAI’s ChatGPT stock portfolio prioritizes companies with recurring revenue, strong balance sheets, and clear demand visibility heading into 2026.
OpenAI’s ChatGPT’s 2026 stock portfolio
At the core of the portfolio is Microsoft (NASDAQ: MSFT), which receives the largest allocation at 25%, or $250. Microsoft’s diversified business model spanning enterprise software, cloud computing, and AI-driven services makes it a natural anchor in an uncertain macro environment. As AI adoption accelerates across corporate workflows,
Azure and Microsoft’s productivity ecosystem provide a direct monetization path while offering downside protection relative to more volatile growth names.
Nvidia remains central to global AI infrastructure
The second-largest position is Nvidia (NASDAQ: NVDA) at 20%, or $200. Nvidia remains central to global AI infrastructure spending, supplying the high-performance chips required for data centers, large language models, and advanced computing workloads.
While the stock can be volatile, the multi-year buildout of AI infrastructure keeps Nvidia firmly positioned as a key beneficiary into 2026.
To complement Nvidia, Broadcom (NASDAQ: AVGO) receives a 15% allocation. Broadcom offers exposure to networking, custom silicon, and AI-related infrastructure while also benefiting from its diversified software and semiconductor businesses. This balance helps smooth returns if AI spending rotates across different parts of the technology stack.
Energy security is another defining theme for 2026, which is why Constellation Energy (NASDAQ: CEG) accounts for 15% of the portfolio. Rising electricity demand from data centers and AI workloads is putting pressure on power grids, and large-scale generation assets stand to benefit from this structural shift.
Geopolitical resilience
Geopolitical uncertainty remains elevated, supporting a 15% allocation to Lockheed Martin (NYSE: LMT). Defense spending tends to stay resilient even during economic slowdowns, providing portfolio stability alongside long-term security demand.
Rounding out the portfolio is Eli Lilly (NYSE: LLY) at 10%. Healthcare offers defensive characteristics, and Lilly’s strong growth outlook helps balance cyclical exposure elsewhere in the portfolio.
Together, this $1,000 portfolio blends growth, defense, energy, and healthcare exposure, aiming to capture opportunity while managing risk as markets head into 2026.
