OpenAI’s ChatGPT has extended its lead over the S&P 500 , with an experimental stock portfolio returning 67.42% since launching with $100,000 in late November 2025.
According to the November 7, 2026, update from Rallies Arena , the portfolio is now worth approximately $167,422, compared with a 9% gain for the S&P 500 over the same period.
ChatGPT is also outperforming every other artificial intelligence ( AI ) model participating in the competition.
The experiment gives leading AI models $100,000 each to invest in the stock market, using real-world financial data and research tools to build portfolios capable of beating the benchmark index.
ChatGPT’s return puts it comfortably ahead of xAI’s Grok, which ranks second with a 31.34% gain.
Anthropic’s Claude follows with 23.05%, while Google’s Gemini has returned 20.56%. DeepSeek has recorded a smaller 3% gain, whereas Qwen is the only participating model in negative territory, down approximately 28%.

Stocks driving ChatGPT’s investment returns
ChatGPT’s portfolio spans technology , AI infrastructure, insurance, financial services, healthcare, energy and defense.
Alphabet (NASDAQ: GOOGL ) benefits from Google Cloud growth driven by AI demand, although rising data center spending has raised capital expenditure concerns.
Progressive (NYSE: PGR) adds insurance exposure through data-driven underwriting and an expanding policy base, while Visa (NYSE: V ) and JPMorgan Chase (NYSE: JPM ) provide payments and banking exposure.
Leidos (NYSE: LDOS) benefits from defense technology and cybersecurity demand, reporting third-quarter revenue and earnings growth before raising its full-year guidance.
Amphenol (NYSE: APH) has recorded strong sales amid rising demand for AI data center connectivity products. Credo Technology (NASDAQ: CRDO) adds exposure to high-speed connectivity solutions, including retimers and optical components, although its shares remain volatile despite rapid revenue growth.
Other holdings include Exxon Mobil (NYSE: XOM ), Cigna (NYSE: CI) and Lockheed Martin (NYSE: LMT ), providing additional energy, healthcare and defense exposure.
What’s next for ChatGPT portfolio
Despite its substantial lead, the experiment is still relatively short, and its results do not establish that AI-managed portfolios can consistently outperform the broader market.
The portfolio’s exposure to high-growth technology and semiconductor infrastructure companies also introduces considerable volatility.
Sharp corrections in these sectors could quickly affect its cumulative returns.
