Why 4C

Built for the bettor,
not one sportsbook.

A sportsbook wants your action locked to its platform and its number. 4C is built around the whole market, so the price you see has to stand up against every other one on screen.

Priced against everything

4C watches the whole market and prices against it, so its number has to hold up. Not just be the first one you saw.

Stop checking five apps

Everything worth seeing in one interface, instead of five apps and a spreadsheet.

Books and markets together

Sportsbooks, exchanges and prediction markets. One view, one app.

Market-quality filtering

Thin and unreliable markets are filtered out, so what you see is worth your attention.

One account, not twelve

No chasing signups, deposits or logins across a dozen venues, and no added fee to port your plays.

The whole market, seen

Reference prices from across the industry, on screen, so you always know what your price is worth.

See the whole market.

Best price every time.

FAQ

Questions, answered.

What is 4C?
One app for sports betting and prediction markets. You get one account, and 4C's prices are set against the whole market: sportsbooks, exchanges and prediction markets.
Who am I transacting with?
You are transacting directly with 4C to purchase legally made sports predictions. Prices from other venues may be shown for comparison and do not imply a partnership with those venues.
How does 4C find better prices?
4C watches sportsbooks, exchanges and prediction markets continuously and prices against them. Displayed prices are indicative until confirmed.
Is 4C a sportsbook?
No. 4C doesn't set its own line and take the other side of you. It's one app pulling prices from across the market, so you're always trading against the best of it. The exact products available depend on your location.
How do orders work?
Get your order out to every venue in the market with one click. 4C confirms what it can fill and at what price.
