In short: a social sportsbook lets you make sports picks with virtual coins instead of cash, and some of those coins can be redeemed for prizes under sweepstakes rules. Social sportsbooks are not state-licensed sportsbooks, and they are not regulated exchanges either. That puts them in a grey zone that several US states have started to close.
This page explains how the model works, where the legal pressure comes from, and how social sportsbooks compare with prediction markets, where you trade event contracts on a regulated exchange.
How a social sportsbook works
Most social sportsbooks use a two-currency system:
- A play-only coin. You get it free or buy it in packs. It is used for entertainment picks and has no cash value.
- A sweepstakes coin. It usually comes as a "bonus" with coin packs, or through free methods such as daily logins or mail-in requests. Winnings in this currency can sometimes be redeemed for prizes or cash equivalents.
Because a free way to get the sweepstakes coin always exists, operators argue that no purchase is necessary and that the product is a sweepstakes promotion, not gambling. That is why they do not hold a sports betting license from a state gaming regulator.
Why states are pushing back
Regulators and lawmakers in several states see the two-currency model as unlicensed gambling in disguise. In 2025, California, New Jersey and New York passed laws restricting sweepstakes-style gaming, and other states have issued warnings or opened investigations. Platforms often respond by blocking users in those states.
For you, that means:
- Availability can change quickly, sometimes with little notice.
- Consumer protections are weaker than with a licensed operator: there is no state regulator checking payouts or handling complaints.
- Redemptions usually require identity checks and minimum balances, and can be refused if your state is excluded.
Social sportsbook vs licensed sportsbook vs prediction market
| Social sportsbook | Licensed sportsbook | Prediction market | |
|---|---|---|---|
| Legal basis | Sweepstakes rules | State gaming license | CFTC-regulated exchange (Kalshi, Polymarket US) |
| What you use | Virtual coins | US dollars | US dollars |
| Who sets prices | The operator | The house (bookmaker) | Other traders |
| Can you exit early? | No | Sometimes (cash-out) | Yes, sell at market price |
| Payout | Prizes via redemption | Cash | $1 per winning contract |
On a prediction market, a contract priced at 62¢ means traders see roughly a 62% chance of that outcome. You are trading with other people, not betting against the house, and you can sell before the game ends. The Kalshi review explains one regulated option in detail.
Prediction markets are not risk-free and are not available everywhere: some states dispute sports event contracts, and Polymarket's international site is close-only for US users. See where Polymarket is legal for the state-by-state picture.
How to choose (and what to avoid)
If you are comparing "best social sportsbooks" lists, look past the bonus offers and check:
- State eligibility for redemptions, in writing, in the terms.
- Redemption rules: minimums, identity checks and processing times.
- Who regulates the product, if anyone, and where complaints go.
- Whether the price reflects a real probability. Convert odds into implied probability and compare them with a market price; our guide to expected value shows how.
Bottom line
Social sportsbooks are designed as entertainment with a prize mechanic, not as a regulated way to trade on sports. If you want prices set by other traders and clear contract rules, a CFTC-regulated prediction market is the closer fit. Whichever you use, only stake what you can afford to lose and set limits before you start.
