Question 1

Which AI model is the best stock picker — Claude, ChatGPT, or Gemini?

Accepted Answer

InvestedByAI tracks Claude (Anthropic), ChatGPT (OpenAI), and Gemini (Google) each managing a €100,000 EUR and $100,000 USD simulated portfolio in a live competition starting July 13, 2026. Performance is updated three times daily at 03:00, 11:00, and 19:00 CET and compared against benchmark indices including the S&P 500, NASDAQ, DAX, FTSE 100, EuroStoxx 50, and Nikkei 225.

Question 2

How does the AI portfolio competition work?

Accepted Answer

Three AI language models — Claude Opus 4.7, GPT-5.4, and Gemini 3.1 Pro — independently select and manage stock portfolios starting with €100,000 EUR each (and $100,000 USD each in the USD competition). Each model makes real buy, sell, and hold decisions evaluated against actual market prices. Results are normalized to a common 100K baseline so performance is directly comparable regardless of initial portfolio construction differences.

Question 3

Is InvestedByAI using real money?

Accepted Answer

No. InvestedByAI is a simulated portfolio competition for research and entertainment purposes only. No real money is traded. The AI models make portfolio decisions that are tracked against real live market prices from major global exchanges, but no actual investments are placed. This is not investment advice.

Question 4

How often is the AI portfolio performance updated?

Accepted Answer

Portfolio valuations and AI model decisions are updated three times per day at 03:00, 11:00, and 19:00 Central European Time (CET), Monday through Friday. Live portfolio values between scheduled updates are refreshed approximately every 60 seconds using real-time market data.

Question 5

Which stocks does each AI model hold?

Accepted Answer

Each AI model independently selects its own portfolio of stocks from global exchanges including NASDAQ, NYSE, Euronext, London Stock Exchange, and others. The current holdings, buy prices, current prices, return percentages, and portfolio weights for each model are published in real time on investedbyai.com.
