Sportsbook sign-up offers: types, value and fine print

What types of sign-up offers exist?

Four shapes cover the offers SlateProof can price: bet and get, win and get, first-bet refund and exchange credit. Several are paid out over days. Deposit matches exist too, but SlateProof does not price them.

• Bet and get: place a qualifying bet, win or lose, and receive bonus bets or credit. Some pay a set amount each day for several days.
• Win and get: the bonus arrives only if the qualifying bet wins, so a heavy favorite is the better qualifier.
• First-bet refund: if your first bet loses, it comes back as bonus bets up to a maximum. This is a no-sweat bet in all but name.
• Exchange credit: a trading credit at an exchange after a deposit or a first trade. Whether the credit comes back after a win decides its value.

Which type of sign-up offer is worth the most?

None wins on its headline size. A first-bet refund of up to $1,500 sounds largest, but you collect the maximum only by risking that much cash, and the refund is a bonus bet. A bet-and-get offer pays for a $5 bet, so it can be worth far more per dollar risked.

The conversion c is what a bonus-bet dollar turns into as cash. SlateProof uses 65% as a default, and hedged conversions on the best day were near 78% in offline tests. The estimates use fair chances, which are assumptions: the real value depends on the qualifying bet you can find. The bonus bets guide shows how to convert the bonus.

What are the sign-up offers at each legal venue?

This table lists the offers in SlateProof's catalog that had not passed their end date on October 6, 2026, the date of this page's last update. Each carries the date its terms were checked, and offers change without notice, so an offer whose end date has passed has ended.

The venue's own app has the final say, and offers are for new customers only. A "not stated" end date means the operator published none. The sportsbooks page and the exchanges page compare the venues themselves.

Can I claim more than one sign-up offer?

Yes, one at each venue, as long as you are a new customer there and in a state where it operates. Each book limits its offer to one per person, and venues verify identity. Opening extra accounts or using another person's identity is fraud and is not something SlateProof helps with.

Because each offer is for new customers only, the order in which you open accounts matters less than whether you can afford the qualifying bets and the hedges. Claiming several at once spreads your cash thin, so many people work through them one at a time as the bonuses arrive.

Do sign-up offers differ by state?

Yes. Some offers exclude states and some have a different amount by state. BetMGM's first-bet refund leaves out several states and swaps in a win-and-get offer in four of them, and BetRivers' refund is $500, $250 or $100 depending on the state.

Check the state pages for which venues are available where you are, and confirm the amount in the app before you sign up.

What are the minimum odds and expiry?

Most offers require a qualifying bet at a minimum price, commonly -500 or longer, and the bonus bets expire within days. The terms recorded for each offer are below, verbatim from the catalog.

A term the operator did not publish is marked as assumed in the catalog, and a figure that is not verified is said so. Bonus bets expire, so plan the conversion before you claim.

How do I convert a sign-up bonus to cash?

Bet the bonus on one outcome at the book and the opposite outcome with your own cash at another venue, sized so both results leave you the same profit. SlateProof's default estimate keeps 65% of a bonus bet, and the best hedges have reached about 78%.

The full method, with a worked example and the exchange fee included, is in the bonus bets guide. The bonus bet calculator gives the hedge stake for your prices. Offers that pay over several days repeat the qualifying bet and the conversion each day.

Do exchanges give sign-up offers?

Yes, usually as trading credits after a deposit or a first trade. Minimum ages are 18 at Kalshi, Polymarket US and ProphetX and 21 at Novig, and availability varies by state.

The estimated value uses the credit's form: a credit used up by one trade converts like a bonus bet (65%), and one that stays in your balance after a win is worth about 95% of face. Exchanges are contested in some states (see the prediction markets guide), so check where each is available before you deposit.
