Big Brain
Capital
A private trading firm in daily fantasy, sportsbook and prediction markets.
All original
Everything in house. We trade our own capital on it first.
Our models
Top-of-the-line models, simulations and projections, all built in house.
Our money
Any outside money is traded on top of our own. Same positions, same terms, same returns.
Our people
We don’t stake outside operations. You trade our bankroll with our models behind you, and keep a share of what you make.
The numbers
Net of entry fees and rake, across all accounts, 2018–2026. Capital is deployed roughly seven months a year.
Return on capital is measured against a bankroll inferred from position sizing — 1.5% of bankroll in play per slate. Past performance does not guarantee future results.
Reach out
No open roles or active raise currently, but neither stays true forever. When that changes, the first calls go to people already on this list.
Join the team
You want to trade a serious bankroll without spending years building one first. You would join the desk, trade our book, and help build the research behind it.

Get in touch →Partnerships
We build and trade everything ourselves today, but we may expand into other markets in the future. If you have a real edge and want to do business, let us know.
