Ohio Sportsbook Minimum Deposit Requirements: What You Need to Trigger Each Welcome Offer
Most Ohio sportsbooks require just $5–$10 to unlock a welcome bonus. See how minimums compare across all major licensed Ohio books.
The verdict is simple: a $5–$10 deposit is enough to unlock the welcome offer at every major licensed Ohio sportsbook. Depositing more than that minimum will not increase a capped bonus — so there is no financial reason to overshoot the threshold. What matters is hitting it exactly, because depositing even one dollar below the qualifying minimum means the offer is never triggered at all.
Ohio sports betting has been live since January 1, 2023, regulated by the Ohio Casino Control Commission (OCCC). With roughly 19 licensed books now active in the state, minimum deposit requirements and bonus structures vary enough that a side-by-side look is worth your time before you commit to any one operator.

How do minimum deposit requirements actually work at Ohio sportsbooks?
Every Ohio welcome offer sets a floor — the smallest deposit amount that activates the promotion. At most books that floor sits between $5 and $10. Miss it and the bonus simply does not activate; there is no retroactive fix once the first deposit clears. Hit it and the offer is live, regardless of whether you deposited $10 or $500. Bonus caps are set by the operator, not by how much you deposit above the minimum.
One common mistake is confusing the deposit minimum with a first-bet minimum. Some books, like DraftKings, frame the trigger around the first wager placed rather than the deposit itself — DraftKings requires a first-time bet of $5 or more to receive up to $100 in non-withdrawable bonus bets (offer valid through 5/31/26). The deposit still needs to fund that bet, but the qualifying action is the wager. Understanding which step triggers the bonus matters more than the dollar amount involved.
It is also worth knowing that Ohio Sportsbook Bonus Bets vs Deposit Match: What's the Real Difference? can affect how useful your welcome credit actually is — a deposit match and a bonus-bet offer both have minimums, but they work very differently once the funds land.
Which Ohio sportsbooks have the lowest minimum deposit requirements?
| Sportsbook | Minimum Deposit to Trigger Offer | Welcome Offer Summary | Key Restriction | Bonus Expiry |
|---|---|---|---|---|
| DraftKings Ohio | Enough to place a $5 first bet | Up to $100 in bonus bets | Bonus bets non-withdrawable; stake deducted from winning payout | 7 days (168 hours) |
| bet365 Ohio | $10 | Bet $5, get $150 in bonus bets if first bet wins | First bet must carry odds of -500 or greater | Per operator terms |
| BetRivers Ohio | $10 | Bonus credit applied to first wager if it loses | Triggered only on a losing first wager | 30 days from issuance |
| BetMGM Ohio | $10 | First Bet Offer up to $1,500 in bonus bets | Refund issued as five equal bonus bets; only if first bet loses | 7 days |
BetMGM's offer carries the highest cap in the table. For a full breakdown of that promotion, including current promo codes, visit BetMGM Ohio Promo Code: $1,500 First Bet Insurance Offer. Note that the refund arrives as five separate bonus bets, not a single credit — a detail that affects how you plan your follow-up wagers.
Does a higher deposit unlock a bigger bonus?
No. Every offer reviewed here sets a fixed cap. A bettor depositing $500 at BetRivers receives exactly the same welcome credit as one depositing the $10 minimum — provided both clear the qualifying first-wager step. The cap is the cap. Depositing extra only puts more of your own cash at risk on that first bet.
Why does the expiry window matter as much as the minimum?
A low minimum deposit gets you into the offer. A short expiry window determines whether you actually use it. DraftKings and BetMGM both expire bonus bets in seven days; BetRivers gives you 30 days. If you travel, forget, or simply do not have a game to bet within that window, the credit disappears with no recourse.
