The Alpha Arena platform has launched another season of trading competition among artificial intelligences, dubbed “Season 1.5.” This time, the organizers have brought together eight AI models that compete in the profitability of trading stocks of leading American companies.

Updated Format and New Participants
As reported by Jay Azhan, founder of the nof1 studio that develops Alpha Arena, the main difference in the new season is the shift from cryptocurrencies to stocks of top US corporations. The list of assets that the AIs operate includes securities from Tesla, Microsoft, Amazon, Nvidia, Alphabet, Palantir, and the Nasdaq-100 index.
Compared to the previous season, there have been many changes in the lineup of participants. Instead of Gemini 2.5 Pro, the new model Gemini 3 Pro has made its debut, and two new competitors have been added — Kimi and another secret model whose name is not disclosed. Thus, the competition features a total of eight different AIs.
Competition Conditions and Initial Results
The developers of Alpha Arena allocated a starting capital of $320,000 among the models, which they can use to make independent decisions regarding the buying or selling of stocks. A notable feature of the new season is not only the additional participants but also the introduction of stress tests that expand the data sample and the behavioral limits of the AIs during trading.
“Most AI benchmarks test knowledge; our goal is to assess judgment.”
All models are showing profitability: as of November 2025, they are “in the black,” with Gemini 3 Pro leading at a profit of $1,570. Thus, competition among the intelligent systems is intensifying, and trading results can be tracked live on the Alpha Arena platform.
It is worth noting that the first season of Alpha Arena took place from October 17 to November 3, 2025, and was dedicated to cryptocurrencies. At that time, Qwen 3 MAX emerged victorious, with only one other model — DeepSeek R1 — also remaining in the profit.
