"Real Investing Experiments. Transparent Results."
I Used ChatGPT to Invest for 30 Days
Can I build a winning stock portfolio and make real money ONLY using ChatGPT to invest? I ran a 30 day experiment to find out and the results were shocking. (Hint: it outperformed the market!)
The Setup – Using ChatGPT to Invest
The rules of this experiment were simple, use only the stocks ChatGPT and its Deep Reasearch Feature provides and NO SELLING!
During this experiment I only used ChatGPT’s Deep Research to construct this portfolio, using this one prompt:
“Make me a 5 stock portfolio of your choosing. No parameters, it can be as risky or risk averse as you want. I’m stacking you against Grok and Gemini so pick well. Don’t be boring.”
This prompt was fabricated soley by myself, in hopes of simulating what the average person would ask ChatGPT when making themselves a similar portfolio.
As a result of this prompt ChatGPT took 3 minutes, 19 sources and 49 searches to selecg the following five stocks weighted in the following way using 10 thousand dollars as standardization:
| Stock | Ticker | Price (Approx) | Weight | $ Allocated | Shares (Rounded) |
|---|---|---|---|---|---|
| PDD Holdings | PDD | $119 | 30% | $3,000 | 25 shares |
| IonQ | IONQ | $12.70 | 25% | $2,500 | 197 shares |
| Rocket Lab | RKLB | $6.30 | 20% | $2,000 | 317 shares |
| Beam Tx | BEAM | $21.90 | 15% | $1,500 | 68 shares |
| QuantumScape | QS | $4.20 | 10% | $1,000 | 238 shares |
Here are short summaries on each of the companies selected:
PDD Holdings (PDD) – A Chinese e-commerce giant behind Pinduoduo and Temu, revolutionizing online shopping through ultra-low prices and viral group-buying.
IonQ (IONQ) – A pioneer in quantum computing using trapped-ion technology, aiming to lead the next computing revolution beyond traditional chips.
Rocket Lab (RKLB) – A space tech company providing frequent satellite launches and end-to-end space services, competing just behind SpaceX.
Beam Therapeutics (BEAM) – A biotech innovator using CRISPR base editing to precisely rewrite DNA and cure genetic diseases with one-time treatments.
QuantumScape (QS) – A battery tech company developing solid-state lithium-metal batteries that could dramatically extend EV range and reduce charge times.
The Rationale – Using ChatGPT to Invest
Following the selection of the stocks I prompted ChatGPT to explain the logic behind each stock, this is what it had to say:
PDD (30%): This is the strongest growth engine with real profits, massive scale, and misunderstood upside. It’s the “anchor” with China/Temu exposure but lower tech risk than the others.
IonQ (25%): Big asymmetric bet on quantum computing leadership, now with capital to expand aggressively.
Rocket Lab (20%): Strong momentum, real revenues, and undervalued vs. its long-term space platform potential.
Beam (15%): The most cutting-edge biotech play here. Smaller weight due to binary clinical risks.
QS (10%): Pure speculative optionality. High reward if it commercializes, but capped for risk control.
2 Weeks Later – Using ChatGPT to Invest
This is how the portfolio performed after 2 weeks in the market:
| Ticker | Performance |
| QS | +9% |
| BEAM | +1.37% |
| RKLB | -0.31% |
| PDD | -15.8% |
| IONQ | -17.01% |
| Total Weighted Portfolio Performance | -8.90% |
During the first two weeks, the portfolio significantly underperformed the market, with its second-largest holding plunging by a staggering 17.01%, closely trailed by the largest position, which was down 15.8%.
During this same time most popular stocks like the ones in the Mag 7 were soaring, although this short term volatility is expected with smaller conviction plays such as the ones featured with this portfolio.
1 Month Later – Using ChatGPT to Invest
| Ticker | Performance |
| QS | +60.20% |
| BEAM | +35.05% |
| RKLB | +4.16% |
| PDD | -11.53% |
| IONQ | -12.23% |
| Total Weighted Portfolio Performance | +11.42% |
Despite the slow first two weeks, the portfolio quickly began to take off to the credit of QS and BEAM who rose 60.20% and 35.05% respectively.
Here is a quick glimpse into why each stock moved the way they did:
PDD Holdings
- China tech sell-off intensified as investors reacted to weak macro data and regulatory jitters.
IonQ
- Strong gains from fresh interest in quantum computing, plus momentum from recent quarterly partnership and deployment news.
Rocket Lab
- Share price rose after announcements of new launch contracts and uplisted Neutron readiness updates.
Beam Therapeutics
- Sharp rebound built on encouraging Phase 1/2 BEAM‑101 data, with technical breakout patterns supporting rally.
QuantumScape
- Explosive surge driven by completion of the “Cobra” battery separator integration, followed by a 37% single-day jump after the announcemen
Conclusion + What’s Next – Using ChatGPT to Invest
During the 1 month experiment the ChatGPT Portfolio ended up returning a solid 11.42% which is more than double what the S&P 500 returned (4.5%).
This portfolio will continue to be active and tracked on the leaderboard page (once I get that up and running).
Every 1-2 months I will be asking ChatGPT to review and update the portfolio to reflect current market and company conditions. Stay Tuned for the same experiment with Grok AI and Gemini to see which AI you should trust.
