What Is StarTrader? A Beginner's Guide to Fantasy Stock Trading

Patrick Mahomes has a share price. So does the rookie running back who just got handed the job, and the closer riding a nine-game save streak.

StarTrader is a simulated trading game built on the sports you already follow. You trade player shares, a virtual fractional stake in what real athletes do across the NFL, NBA and MLB. This guide covers what that means in practice, how the pieces fit together, and where it parts ways with the fantasy sports you already know.

The core idea: a market for athletes

When a player performs, whether that's a breakout game, a record night or a deep playoff run, demand for his shares rises and the price climbs. When he slumps, gets hurt or loses a starting role, it falls. The market comparison fantasy writers already use turns out to hold up, pointed at people you already watch on Sundays.

Nothing here hands out points on a fixed formula. Prices move the way real markets move, through performance, news, and supply and demand. Your job is to read that market better than the other nine people in your league. Buy low, hold smart, sell at the right time.

StarCoins: the currency that runs everything

Every action on StarTrader is denominated in StarCoins (SC), the game's virtual currency. You spend them on player shares and ETFs, and to fund league accounts. You earn them several ways:

• Daily login streaks. The longer your consecutive run, the bigger the bonus (Pro earns 1.5x, Elite 2x).
• Monthly stipends for subscribers: 200 SC/month on Plus, 500 SC/month on Pro, 2,000 SC/month on Elite.
• League performance, with StarCoins moving between members' accounts at the end of a season based on the standings.
• Referrals when friends sign up and make their first trade.

Three things that set StarTrader apart

1. The price is the scoreboard

Traditional fantasy locks you into a weekly lineup and a points formula, then makes you wait until Tuesday to do anything about it. StarTrader runs continuously. A player's value reflects live performance, breaking news, and how badly people want the shares right this minute. You can act on a report the moment it lands.

2. Strategy runs deeper than picking winners

Holding periods, tax rates, order types, float size and diversification all matter here. The single most valuable habit is patience: the longer you hold a winning position, the less tax you pay when you finally sell.

Flipping fast feels productive and quietly eats your returns.

3. Leagues are genuinely competitive

A league is a private group trading against each other over a season. When it ends, the final standings decide how members' virtual holdings, meaning their player positions and their StarCoins, transfer between accounts. All of it is in-platform virtual currency with no cash value. The commissioner sets the tax rules, which shape the entire economy of the competition.

Where to go next

That's the whole loop: earn StarCoins, build a portfolio, trade the market, manage your tax exposure, compete in leagues. If you want to go deeper, the market guide breaks down exactly what moves a player's price, and the tax guide shows how holding periods can cut your rate in half.
