Free Dollar Bet Promos

Platforms want new users. New users want free stuff. Occasionally these interests align and someone gives you a dollar to play with. This page tracks the current promotions from prediction markets and sportsbooks where you can start with house money — or at least a modest subsidy.

Kalshi periodically offers sign-up bonuses and referral credits. The specifics change — sometimes it's a deposit match, sometimes it's free contracts, sometimes it's a referral bonus for both parties. Check the current offer through our link, which may include a referral bonus. Other platforms like Polymarket have run similar onboarding incentives at various points.

Major sportsbooks regularly offer new-user promotions: bet $5 get $150 in bonus bets, first-bet insurance, deposit matches. These rotate frequently and vary by state. The catch is always in the terms — bonus bets usually can't be withdrawn directly, and wagering requirements apply. Read the fine print. Then read it again.

No platform is giving you money out of kindness. Free bet promotions are customer acquisition costs — the platform is betting that once you sign up, you'll deposit real money and keep trading. That's fine. That's how business works. Just know the game you're playing before you play it.

Bonus bets typically expire within 7-14 days. They usually can't be combined with other offers. Winnings from bonus bets may exclude the stake amount. Some promos require a minimum deposit before the bonus activates. None of this is hidden — it's just buried in terms pages nobody reads.

If you're getting house money, the mathematically rational move is to use it on the highest-payout longshot available. You're not risking your own cash, so the expected-value calculus shifts. A free $1 on a contract priced at 2 cents has the same downside as not having the dollar — zero — but the upside is $50. This is the one situation where going full degenerate is actually the smart play.

We update this page as offers change. If a promo listed here has expired, let us know. We don't list offers we haven't verified, and we don't inflate the value of promotions to make them sound better than they are. Every link on this page is an affiliate link — we earn a commission if you sign up. That's how we keep the lights on.
