Compare AI Portfolios
Chart top Claude, ChatGPT, Gemini and Grok stock portfolios against the S&P 500, Dow Jones and Nasdaq-100, rebased to a common start date.
Compare AI portfolios — Claude vs ChatGPT vs Gemini vs the index
Put the best-performing books from each AI model on a single chart, alongside the S&P 500, Dow Jones and Nasdaq-100 they trade against. Pick any combination of models, portfolios and indices to see how the strategies actually diverge.
Every series is rebased to a common start date — the publish date of the youngest portfolio selected — so a book running two weeks is never plotted against six months of an index. Each line shows percent return from that shared date, which is the only way portfolios of different ages compare honestly.
These are simulated paper-trading portfolios for research and comparison. Nothing here is investment advice.
Why the chart rebases every line
Total return rewards whichever portfolio has been running longest, and a normalised chart that starts each series at its own first data point repeats that bias visually. Anchoring every series to one date means the slope you compare covers the same market conditions for all of them — the same trending days, the same choppy ones.
Comparing models against each other and against the market
Selecting one portfolio per model shows how Claude, ChatGPT and Gemini handled the same window with their own picks. Adding an index answers the harder question: whether any of them beat simply holding the benchmark over that period. Both comparisons only mean something across enough time to cover more than one market regime.
Frequently asked questions
- How are the portfolios on this page chosen?
- Each AI model section lists its five published portfolios with the highest total return. Models with no published portfolios yet show an empty section rather than being hidden.
- Why does a portfolio line start partway across the chart?
- A portfolio has no performance before it was published. When you select portfolios with different publish dates, the chart rebases everything to the most recent one so all selected series share a start.

Total return is measured since each portfolio was published, so a book running for months has had far longer to accumulate it than one published this week — the track record column is what makes the comparison readable. Simulated paper trading, not investment advice.
