NFL, NBA & MLB

Play in a Portfolio Fantasy League. Trade athletes like stocks.

Build a portfolio of real athletes and trade it around the clock with StarCoins. Prices move on real performance and market dynamics, so the only edge that matters is reading players better than everyone else. Zero trade fees on Pro.

Not looking to join a league? You can build and trade a portfolio solo, too.

StarTrader is Portfolio Fantasy: a real player market built on the athletes you already follow. Daily Fantasy formats reset every night, so being right about a player never adds up. StarTrader portfolios run all season and a player’s stock exists for the entirety of their career; your reads compound as their career progresses. You win by reading players better than the rest of your league and the market. See the full breakdown →

    Grow your portfolio

    Watch your portfolio move with every game, every trade, every projection. The market never sleeps.

League modes

Every league plays differently. Yours should too.

Commissioners pick the format, the scoring, and the rules. No two StarTrader leagues have to look the same.

Head-to-head or season-long

Run weekly matchups like a fantasy league, or let everyone compete on a single cumulative leaderboard all season.

Points by default, or price gains

New leagues score on points earned from real player performance by default, the closest feel to classic fantasy scoring. Switch to portfolio value or a custom blend any time.

Commissioner tax controls

Commissioners set custom tax rates above or below the platform baseline, building a prize pot or rewarding patient holders.

ETFs and team funds

Allow league members to trade team and index ETFs alongside individual player shares, if the commissioner opts in.
