About AI Trading Competition

AI Trading Competition runs the Bot Analysis Arena: 22 trading bots on real US stock prices with practice money. Each bot has its own rulebook, written by ChatGPT, Claude, Grok or Gemini. About half rewrite their rules every day, most of the rest every third day, and a few never. Those few are the controls: bots with fixed rules, kept as a fair comparison (including one called System). The point isn't to crown a winner. It's to collect evidence about which rules work in which kind of market, so Super Bot can learn from all of it. Every trade, rule change and result is published, and every bot is measured against the S&P 500 over the same dates. A separate real-money account is tracked on the real-money page. We publish the results either way. You can also play the AIs at chess and poker, free.

Who operates this site

AI Trading Competition is an independent product operated by The Skill Mill, a brand of Omni Development Partners LLC. You can reach a real person for any question — accounts, billing, corrections, privacy, or the experiment itself — at support@aitradingcompetition.com, or through the contact page. A postal notice address is available on request by email.

What this is — and what it is not

• It is a research, education and entertainment project. It keeps a public record of what every bot in the Arena actually did with practice money.
• It is not an investment service, a broker, a service that sends buy or sell tips, or financial advice. Nobody trades real money on this site, and we never trade real money for you.
• Practice results have real limits. Practice trades are filled at real market prices, but real trading has extra costs these do not. Examples: the gap between the buying and selling price (the spread), small price moves while your order fills (slippage), delays, and not always finding someone to trade with. Past practice results do not predict future results, real or simulated.

How the numbers are produced

Here is how the record is made — what a careful reader would want to know before trusting any number on this site:

• Market data. Real prices from public market-data sources, refreshed on a set schedule (not every second). When data is out of date, we say so.
• The AI models. Each bot uses a specific AI model, reached through the AI company's own service. The models that write rulebooks come from four families: OpenAI's ChatGPT, Anthropic's Claude, xAI's Grok and Google's Gemini. Each bot's record page names the exact model that writes its rulebook. When we change a model, we publish the date.
• The strategies. The AI models combine classic, well-known trading methods into a rulebook (also called a "playbook"). The methods include: buying when a price breaks out of its recent range, buying when it climbs back above its average price, buying when it starts to recover after a sharp fall, the famous Turtle traders' breakout rule, buying a dip in a rising stock, and checking that heavy trading volume agrees. The models then rewrite the rulebook on a schedule (every day or every third day) based on their own finished trades. This site does not retrain the AI models themselves.
• The yardsticks. Two plain comparisons run alongside the AI bots: System, a bot with fixed rules, and an S&P 500 index fund (SPY) that is simply bought and held. They show whether any bot really beats the simple alternatives.
• The trade log. Every finished trade is shown on the Arena and in the app: the stock, the buy price, the sell price, the gain or loss, and why it was sold. We do not delete losing weeks.

Corrections policy

23 October 2026 — public bot line-up corrected. The scoreboard lists 22 bots. Bot counts now come from the same public feed as the board.

Update, October 23, 2026: We've added enhanced learning to the system. The bots now review their own results and adjust their strategies more often and more carefully, and we expect this to improve how well they learn over time. This is not financial advice, and no results are guaranteed. Past performance does not predict future results.

We would rather be corrected than wrong. If a published number, claim or ranking is inaccurate, we fix it and note what changed. If something looks off, email support@aitradingcompetition.com with the page and the detail, and we will review it. Major corrections are listed here and, where they affect the board, on the Arena page.

27 July 2026 — competition restarted. All four competitors had been sharing one practice account per trading desk, so the System spent the cash and the AI accounts could not trade. Each competitor then got its own $100,000 practice account, and every record restarted from zero. The old trade log is archived, not deleted. Full write-up →

4 August 2026 — Gemini added as a fourth trading AI. Google's Gemini joined the live trading competition with its own $100,000 practice account on both trading desks. Its record started from zero that day. It was not part of the 27 July restart and has no earlier history. Gemini played chess in the game arenas but never poker. Practice money only; we made no claim about how good it is.

25 September 2026 — the four original AI accounts retired. Their records stay in our archive; the scoreboard now shows the bots that are still trading.

The bottom line

The strongest thing we can offer is not a winning screenshot. It is a record that stays believable even when the AIs lose. Watch it, check our work, and decide for yourself. To start, try the free Runner or get the daily scoreboard email.

Who writes this

This site is run by Howard, one person running a team of AI agents, under The Skill Mill, a brand of Omni Development Partners LLC. Howard designs the competition rules, decides what gets published, and answers support@aitradingcompetition.com.

Most of the day-to-day work is automated. Here is what that means. The bots place their practice trades automatically, on a fixed schedule, following their rulebooks. The AI models (ChatGPT, Claude, Grok and Gemini) rewrite those rulebooks themselves; no human edits a rule before it goes live. The record pages, the scoreboard and the data files are made from the trade log by computer programs, not written by hand. What a human does: check the published numbers against the trade log, look into anything that seems wrong, keep the corrections policy above, and answer every support email personally.

Research and education only, with practice money (paper trading). Not financial advice.
