This ChatGPT November portfolio just destroyed the S&P 500
TITLE: OpenAI ChatGPT Portfolio Surges Past S&P 500 In AI Investment Challenge
OpenAI’s ChatGPT has established a massive lead over the S&P 500, with an experimental investment portfolio generating a 67.42% return since its inception in late November 2025. According to a performance update released by Rallies Arena on November 7, 2026, the portfolio has grown from its initial $100,000 investment to a current valuation of approximately $167,422. This performance significantly outpaces the S&P 500, which recorded a 9% increase during the same timeframe.
AI Models and Market Performance
The ongoing experiment allocates $100,000 in virtual capital to several prominent artificial intelligence models. These systems utilize real-world financial data and various research tools to construct stock portfolios designed to beat the market benchmark. In this head-to-head competition, ChatGPT is currently outperforming all other participating AI models. Its nearest competitor is xAI’s Grok, which holds second place with a return of 31.34%.
Other artificial intelligence models in the challenge are trailing further behind. Anthropic’s Claude has achieved a 23.05% gain, while Google’s Gemini has seen a return of 20.56%. DeepSeek has managed a modest 3% increase. In contrast, Qwen is currently the only model in the group to post a loss, with its portfolio down by roughly 28%.
Technology Infrastructure and Financial Holdings
The portfolio managed by ChatGPT is diversified across several sectors, including technology, financial services, insurance, AI infrastructure, healthcare, energy, and defense. Alphabet (NASDAQ: GOOGL) is a primary holding, as the company sees growth in its Google Cloud division fueled by AI requirements. However, the model also accounts for investor concerns regarding high capital expenditures tied to rising data center costs.
In the financial and insurance sectors, the portfolio includes Progressive (NYSE: PGR), which utilizes data-driven underwriting to expand its policyholder base. It also holds Visa (NYSE: V) and JPMorgan Chase (NYSE: JPM) to maintain exposure to the banking and payments industries. Within the technology and connectivity space, Amphenol (NYSE: APH) has contributed to the portfolio’s success due to high demand for products used in AI data center connectivity. Credo Technology (NASDAQ: CRDO) provides additional exposure to high-speed optical components and retimers, though its stock remains subject to volatility despite its fast revenue expansion.
Defense Energy and Healthcare Sectors
The defense sector is another major component of the ChatGPT strategy. Leidos (NYSE: LDOS) is a notable inclusion, benefiting from the current demand for cybersecurity and defense technology. The company recently reported growth in both revenue and earnings for the third quarter and subsequently increased its financial guidance for the full year. Other significant holdings in the portfolio include Lockheed Martin (NYSE: LMT), Exxon Mobil (NYSE: XOM), and Cigna (NYSE: CI), which offer the portfolio broad exposure to the defense, energy, and healthcare markets.
While the current returns are substantial, Rallies Arena notes that the experiment has only been running for a relatively short period. These early results do not guarantee that AI-driven portfolios can maintain such performance over the long term. Furthermore, the heavy concentration in semiconductor infrastructure and high-growth technology stocks means the portfolio is subject to significant market volatility.
