Fantasy Stock Market Game with Real Market Moves
A fantasy stock market game works like fantasy sports: instead of drafting athletes, you draft real stocks, and your lineup scores when those stocks move in the real market. In StockAlpha's Salary Cap contests you get 50,000 Star Coins to draft 8 stocks, everyone plays with the same budget and prices, and the lineup with the highest average return wins.
It's free during beta and uses practice currency only, so you can learn how stocks behave, and how your own judgment holds up, without risking money.
How the fantasy stock draft works
- Pick a contest with the Salary Cap badge in the Alpha Contests lobby. Contests range from daily sprints to multi-week leagues.
- Fill 8 slots and stay under 50,000 Star Coins (SC). Use the Stars, Value and Contrarian filters to shop the slate. You can take no more than 4 stocks from any one sector, so all-tech lineups are out.
- Lock in. Lineups lock at 3:45 AM ET on contest day, before the premarket opens. Edit freely until then.
- Score on real moves. All 8 picks count equally, and your score is the lineup's average return. Follow along on the leaderboard.
Star Coins are only your draft budget inside a contest. Contest entry uses Alpha Coins, a separate practice currency you get free when you sign up. Neither has any monetary value.
Why stocks cost different amounts
Like a daily fantasy sports slate, the stocks expected to move the most cost the most. StockAlpha's engine prices its roughly 500-stock universe each evening using five signals:
- AI conviction: the Alpha Picks ranking model's expected edge, meaning its score multiplied by its confidence.
- Momentum: how the stock has trended over the last one to three months.
- Volatility: how big its typical daily swings are, weighted up in daily contests.
- Catalysts: upcoming events such as earnings or a Fed decision, also weighted up in daily contests.
- Size: mega-caps carry a star premium, like marquee players.
Prices are matched to the contest's length: daily contests lean on short-horizon signals, while longer contests lean on the model's 5-day and 21-day outlooks. Prices freeze the moment a contest is created, so nothing reprices mid-contest. One caution: the Alpha Picks model behind the "AI conviction" signal is in internal preview and has not shown a statistically significant edge, so a high price is the model's opinion, not a sure thing.
Salary Cap vs. weighted lineups
In many stock contests, everyone piles into the same handful of popular names. A salary cap changes that. Because stars are expensive, nobody can afford the whole hot list, and the edge goes to players who find value the pricing has missed. Everyone gets an identical slate and budget, so there's no head start from a bigger bankroll.
If you'd rather set your own position sizes, contests that don't use Salary Cap mode use weighted lineups, with limits on how much can go into one stock or sector. The lobby's type filter covers Classic, Head-to-Head, Double Up, League, Multiplier, GPP and Sector Showdown contests. See our stock picking contest guide for how scoring, prizes and the Alpha Score work across formats.
Draft strategy for beginners
These are game tactics for a practice contest, not investment advice:
- Stars and scrubs. Two expensive stars plus six value picks is a legitimate build. Evenly balanced lineups rarely top a leaderboard.
- Shop the Value column. It shows signal per 1,000 SC, highlighting stocks the engine likes more than their price suggests.
- Respect the earnings badge. Stocks heading into earnings carry a premium because the move can go either way. Pay it on purpose, not by accident.
- Read before you draft. Check the AI report on a stock's ticker page, for example NVIDIA (NVDA), and note the report date.
To understand why prices swing, read understanding market volatility and how to read an earnings report.
Fantasy stock game vs. paper trading vs. real investing
| Fantasy stock game (Salary Cap) | Paper trading | Real investing | |
|---|---|---|---|
| What you manage | A fixed 8-stock lineup for one contest | A simulated account you trade over time | Your own money |
| Budget | Same 50,000 SC for every player | Usually a set amount of fake cash | Whatever you invest |
| How you win | Beat other players' average return | No winner; you track your own results | Meet your own goals over years |
| What's at risk | Practice coins only | Nothing | Real money |
Our guide to paper trading covers the simulator approach in more detail.
Who it's for
- Fantasy sports fans curious about the stock market who want a familiar draft format.
- Beginners who want to learn how prices react to earnings, news and volatility without risking savings.
- Students and clubs looking for a free, friendly competition. Each person needs their own free account.
Honest limitations
- It's a game. Short contests are heavily influenced by luck, and a winning fantasy lineup is not a sensible real portfolio.
- Practice currency only. Star Coins and Alpha Coins have no monetary value, and there are no cash prizes.
- Model-driven prices can be wrong. Draft prices come from AI signals plus market data; no model predicts a single trading day with certainty.
- Real costs are missing. Taxes, fees and slippage don't exist in the game.
How it compares
Some fantasy stock games focus on cash prizes or trading streaks. StockAlpha's version pairs a DraftKings-style salary cap with free AI research on every stock in the draft pool and a learning library, using practice coins only.

Frequently asked questions
How is a fantasy stock market game different from paper trading?
Paper trading simulates a brokerage account you manage over time with no winner. A fantasy stock game is a contest: you draft a fixed lineup under the same rules and budget as other players, and the best-performing lineup wins.
How many stocks are in a fantasy stock lineup?
In StockAlpha's Salary Cap contests, 8 stocks, bought with a 50,000 Star Coin budget, with no more than 4 from any one sector. Other formats set their own pick limits, shown on each contest.
Why do some stocks cost more Star Coins than others?
Each evening the engine prices every stock using AI conviction, momentum, volatility, upcoming catalysts and company size. Stocks expected to move the most cost the most, like star players in daily fantasy sports.
What's the difference between Star Coins and Alpha Coins?
Star Coins are the draft budget inside a Salary Cap contest (50,000 SC per lineup). Alpha Coins are the practice currency used to enter contests and paid out to winners. Neither has monetary value.
Can draft prices change after I pick my lineup?
No. Star Coin prices freeze when a contest is created and don't move mid-contest. Your picks are final once the lineup locks, at 3:45 AM ET on contest day for Salary Cap contests.
What other contest types can I play besides Salary Cap?
The lobby lists Classic, Head-to-Head, Double Up, League, Multiplier, GPP and Sector Showdown contests. Salary Cap is a draft-style lineup mode that some of these contests use. The rest use weighted lineups, where you choose how much of your lineup goes into each stock within set limits.
