Can AI Beat the Market?
Yes, in this paper-trading record. Google's Gemini family finished ahead of both the S&P 500 benchmark and Bitcoin across nine seasons on TradeRank.ai. Compounding its season returns from December 22, 2025 to September 12, 2026 turns a hypothetical $10,000 into $12,765. The S&P 500 benchmark, SPY, reaches $11,653 over the same nine season windows. Bitcoin reaches $7,776. Each competition account reset to $10,000 at the start of a season; these totals reconstruct the returns rather than track one continuously funded account.
Gemini was the only one of 13 model families ahead of the S&P 500 on the full-window table. Five beat it when compared only over the seasons they traded. Gemini's lead came mainly from crypto; US stocks were tradeable in only Seasons 2, 7 and 8. Beating a stock-market benchmark through crypto trades does not establish stock-picking skill, and picking the winner after the results does not show it will win again. The all-time leaderboard adds the live season to this historical record.
TradeRank Arena at a glance (as of 2026-10-10): 69 AI models have traded across 10 seasons since January 2026 — 2,921 trades, $1090K simulated capital, 43.1% of model-seasons profitable. Drawn entirely from completed seasons, this piece weighs whether AI has beaten the market so far; the live leaderboard shows where the current field stands.
This article is for educational and entertainment purposes only. Nothing here is financial advice. Every trade described is from a simulated competition that uses live market prices and simulated capital; no real money is at risk. Past simulated performance does not predict future results.
How the Record Is Kept
Every season, each model starts with $10,000 of simulated capital and trades at live market prices, with a 0.1% fee on every trade. Within a season every model gets the same market data, the same cash and the same rules, though a few models joined a season late. The rules changed between seasons. Season 1 traded five crypto pairs on four-hour cycles. US stocks were tradeable only in Seasons 2, 7 and 8; the other six seasons were crypto only. Season 8 traded 10 crypto pairs and 50 US stocks, with one decision cycle a day at 16:00 UTC. How It Works has the current design.
The all-time table follows one model family per AI lab. It compounds each season's percentage return on a hypothetical starting $10,000, even though the actual paper accounts reset each season. A season with no final standing for a family counts as 0%, as if its money waited in cash. That includes seasons it sat out and the missing Season 2 results explained below. Bitcoin and SPY compound over the same season windows, with no return assigned to gaps between seasons. This is a comparison of those windows, not uninterrupted buy-and-hold from December to September.
SPY is the ETF used as the S&P 500 reference. Its benchmark measures price changes and excludes reinvested dividends; it is not the index's total return. The models' returns include their simulated trading fees, while the benchmark has no simulated entry or exit trading fee.
The table leaves out contrarian agents, which took the opposite side of another model's decisions. It also leaves out user-submitted entrants, the Season 1 house agent Agent GG and Season 8's stealth entrant ox-alpha. The arena banner above covers a broader set of entrants; the tables here cover the 13 model families.

Gemini finished $1,112 ahead of the S&P 500 and $1,402 ahead of Mistral, the next family. Six families finished between the index and their starting $10,000: Mistral, Nemotron, Inkling, Muse, MiniMax and Qwen. Six lost money: Kimi, GLM, Grok, GPT, DeepSeek and Claude. Claude is the only family below Bitcoin.
Ten of the 13 families traded fewer than nine seasons, so this table measures them against benchmarks that compounded through seasons they did not trade. The table of each family's own seasons below corrects for that.
Gemini, Season by Season
| Season | Dates | Gemini | S&P 500 | Bitcoin | Finish |
|---|---|---|---|---|---|
| Season 0 | Dec 22 – Jan 11 | +0.21% | +1.98% | -2.26% | 2nd of 4 |
| Season 1 | Jan 11 – Feb 8 | +5.96% | -0.50% | -22.42% | 2nd of 9 |

Season 0 began on December 22, 2025; every other date is in 2026. Finish is Gemini's place among every entrant that season, contrarian agents and user entrants included.
How Gemini Beat the Index
Gemini's lead came from three big seasons: 5, 8 and 1. It beat the index in only four of nine: Seasons 1, 5, 6 and 8. In Season 3 the S&P 500 rose 10.08% while Gemini lost 2.64%, a gap of 12.72 points. In Season 4 it trailed the index by 0.01 points.
Season 5 was the largest: Gemini won it at +13.76% while the S&P 500 rose 0.15% and Bitcoin fell 15.01%. Season 8 added +8.60% while the index fell 1.20%. Season 1 added +5.96% while Bitcoin fell 22.42%.
Those gains were crypto gains. Seasons 1 and 5 were crypto only. In Season 8 Gemini's closed crypto trades realized +$1,032.57 and its closed stock trades lost $160.69. Its closed stock trades also lost $190.01 in Season 2. These figures come from the archived stock and crypto trade records. They describe realized trade P&L, not the compounded totals above. Season 7 also allowed stocks, but its reconstructed record does not provide the same verified trade split.
Its losses stayed small. Gemini lost money in four seasons, and the worst was -3.46% in Season 2. Its largest drawdown inside any season was 8.84%, in Season 5, the season it won. That is a within-season drawdown, not the drawdown of a continuous nine-season account.
The lead over the index changed hands five times. After Season 7, with one season left, Gemini stood at $11,754 and the S&P 500 at $11,794. Season 8 put Gemini $1,112 ahead.
Most AI Models Did Not Beat the Market
The other twelve families finished behind the S&P 500 on the full-window table. Their participation varied, so the same-seasons comparison below is the better test for late joiners. The average of all 13 families' compounded balances was $9,817, while the index reached $11,653 from the same hypothetical $10,000.
Most of the damage came from one or two deep seasons. Claude lost 20.97% in Season 1. Getting back to even from there takes a 26.53% gain, and over its six later seasons Claude lost 1.46% in total. DeepSeek lost 16.98% in Season 1 and 11.66% in Season 3. Grok lost 15.90% in Season 3. Gemini never lost more than 3.46% in a season.
Bitcoin was the easier benchmark. It fell in seven of the nine seasons, so a family could lose money and still finish ahead of it. Kimi, GLM, Grok, GPT and DeepSeek all did. All five still ended below $10,000.
Each Family Over Its Own Seasons
| Model family | Seasons | $10,000 became | S&P 500, same seasons | Bitcoin, same seasons |
|---|---|---|---|---|
| Gemini | S0–S8 | $12,765 | $11,653 | $7,776 |
| Mistral | S5–S8 | $11,363 | $10,260 | $10,213 |
| Nemotron | S6–S8 | $10,934 | $10,244 | $12,018 |
| Inkling | S7–S8 | $10,765 | $10,292 | $12,025 |
| Muse | S8 | $10,463 | $9,880 | $12,338 |
| MiniMax | S2–S8 | $10,356 | $11,484 | $10,255 |
| Qwen | S1, S3–S8 | $10,011 | $11,736 | $8,434 |
| Kimi | S1, S3–S8 | $9,533 | $11,736 | $8,434 |
| GLM | S3–S8 | $8,749 | $11,795 | $10,872 |
| Grok | S0–S8 | $8,488 | $11,653 | $7,776 |
| GPT | S0–S8 | $8,355 | $11,653 | $7,776 |
| DeepSeek | S1, S3–S8 | $8,287 | $11,736 | $8,434 |
| Claude | S0–S1, S3–S8 | $7,556 | $11,969 | $8,244 |
This table compounds each benchmark only over seasons with a final standing for that family. Mistral, which joined in Season 5, reached $11,363 from a hypothetical $10,000 while the S&P 500 reached $10,260 and Bitcoin $10,213. It is the only family besides Gemini ahead of both. Nemotron, Inkling and Muse finished ahead of the S&P 500 over their seasons but behind Bitcoin, which rose 23.38% in Season 8.
On this basis five of 13 families beat the index. Gemini is the only one that did it over all nine seasons. For Claude, DeepSeek, Kimi and Qwen, both the family and benchmark totals skip Season 2, even though those families traded its first days. Their final standings are missing. This table matches the available standings, not every day each family actually traded.
Can ChatGPT, Claude or Grok Beat the Market?
Not in this record. GPT, the family for OpenAI's models, turned $10,000 into $8,355 over nine seasons. Grok ended at $8,488. Claude ended at $7,556, last of 13. All three finished behind the S&P 500 and below $10,000. GPT and Grok finished ahead of Bitcoin; Claude did not.
Claude's Season 8 was different: +6.75%, ahead of the S&P 500 at -1.20% and behind Bitcoin at +23.38%. One season does not undo a 20.97% loss in Season 1. The current versions are GPT-6 Astra, Claude Fable 5.1 and Grok 4.6, and the live leaderboard shows how they stand in Season 9.
What Real-Money AI Funds Show
AIEQ provides a longer real-money comparison. The Amplify AI Powered Equity ETF launched on October 17, 2017. Its sponsor describes a stock-selection strategy using IBM Watson through EquBot, a different system from the language models tested here.
24/7 Wall St reported on August 26, 2026 that AIEQ had gained 100.2% since inception against roughly 199.7% for the S&P 500 over the same period. Those are the publication's dated figures; it does not specify whether both include reinvested dividends. Treat them as reported context, not a verified comparison of total returns.
AIEQ's record spans nearly nine years of real-money stock investing. Ours covers about nine months of paper trading, mostly in crypto. One fund's result does not establish how all AI strategies perform, and Gemini's result does not predict that fund's returns.
What This Record Does Not Show
It does not show real-money results. Every trade fills at a live market price with a 0.1% fee, but the capital is simulated and no order reaches an exchange.
It does not show that Gemini will beat the market next season. One family out of 13 finished ahead of the index, and nine seasons are too few to rule out luck. Gemini's running total was behind the S&P 500's after four of its nine seasons.
It does not follow one model. Google's family ran four Gemini versions: 3.0 Flash in Seasons 0 to 2, 3.1 Pro in Seasons 3 and 4, 3.5 Flash in Seasons 5 to 7 and 3.7 Flash in Season 8. The prompt, the asset list and the decision schedule changed between seasons too.
Season 7's results are provisional: its records were rebuilt after the machine that ran it was lost.
Claude, DeepSeek, Kimi and Qwen traded the first days of Season 2 but are missing from its final standings. The table counts that season as 0% for them. All four lost money in those days, between 0.76% and 3.39%, so their totals here are slightly better than their full record.
What It Means If You Trade With AI
The average family ended at $9,817, and the worst at $7,556. Claude lost 20.97% in Season 1, which ran four weeks. That loss is an observed result, not a ceiling on what an AI strategy can lose. Gemini leads this archive, but a winner selected after the results is not a strategy chosen and tested in advance.
To assess another AI trading claim, ask whether it uses real or simulated money, compares the same dates and assets, includes fees and dividends, and keeps the same model and rules. A return above a benchmark alone does not establish better returns for the risk taken.
Season 9 runs from September 12 to October 10, 2026, with 18 models, two of which joined mid-season. The all-time leaderboard folds the live season into the table as it trades.
Methodology
Season returns come from each season's final standings, as published on the competition archive. The chained value is $10,000 multiplied by (1 + return) for each season in order. Benchmark returns are buy-and-hold over each season's window. That can differ slightly from the figure in a season's report, which measures from its own seed date. The table covers Seasons 0 to 8, which settled on September 12, 2026. The data behind every season is in the open dataset.
