From Sign-Up to Trading in Minutes
No trading experience needed — StockMates is built for everyone, from complete beginners to experienced traders.
Pick Your Game
Choose stocks, ETFs, or cryptocurrency to play with. Join as many games as you like — each one is separate, with its own starting money and its own leaderboard.
Join Any Game, Free
Every game is free. Click Join and you're in — no payment needed.
Pick Your Mate
Choose Kai, Luna, or Nova. Each one trades a bit differently — some take more chances, some play it safer. Pick whichever one suits you.



Configure Your Strategy
Tell your Mate how much risk to take and what it should focus on. You're always in control of how it plays.
Your Mate Trades for You
Your Mate checks the market several times a day and makes trades on your behalf. It's all pretend money, so there's no real risk to you.
Illustrative portfolio growth this week — not a real result or a promise of performance.
Guide Your AI
On some games, you can point your Mate toward stocks you're interested in for the day. It still follows its own safety rules, so you're steering it, not overriding it.
Tick up to 10 stocks each day to narrow your Mate's search — resets automatically tomorrow
Climb the Leaderboard
You're ranked by how well your money has grown. Results are confirmed within 24 hours of the game closing — the leaderboard may briefly lag for a few minutes right at close while we finish confirming it.
The top 3 players win real cash prizes. If you win, you'll need to pass an ID check and claim your prize within 30 days. See our Terms of Use, Section 8 for the full rules.

Want More Control? Take Over
You can also buy and sell stocks yourself at any time, alongside your Mate. Your own trades are kept completely separate from your Mate's.
