A sportsbook stake factor is a number an operator assigns to an account to raise or lower its default maximum bet. A lowered stake factor is the most common kind of betting limit, but not the only one: regulators also count market restrictions, withdrawn betting facilities and account closures, which affect what you can bet in different ways.
What a sportsbook stake factor is
The Massachusetts Gaming Commission defines stake factor as the number an operator assigns to a player to raise or lower the default maximum bet that would apply on the day the account was created.[1] A player on a lowered stake factor can still bet, but only up to a fraction of the normal maximum.
In the Commission's data, about 0.64% of accounts had been limited as of December 10, 2024, and most limited accounts were cut hard:[1]
| Limited to (share of the default maximum) | Share of limited accounts |
|---|---|
| Less than 1% | 12.7% |
| 1–24% | 57.6% |
| 25–49% | 11.9% |
| 50–74% | 14.3% |
| 75–99% | 3.4% |
Other types of sportsbook limits
Great Britain's Gambling Commission asked operators about restrictions on about 14.9 million active accounts in 2024. It counted four types:[2]
| Type of restriction | Share of active accounts | Share of restricted accounts |
|---|---|---|
| Stake factor restrictions | 2.68% | 62.17% |
| Account closures for commercial reasons | 2.23% | 51.69% |
| Withdrawn betting facilities (including a 0.00 stake factor) | 0.83% | 19.15% |
| Market restrictions | 0.25% | 5.72% |
| Any restriction | 4.31% |
The shares of restricted accounts add up to more than 100%, so many restricted accounts had more than one type.
- Stake factor: you can bet, but less.
- Market restriction: you can't bet certain markets, or bet them only at reduced stakes.
- Withdrawn betting facilities: the account stays open but you effectively can't bet.
- Commercial closure: the operator closes the account.
Limits you set yourself are different
All of the above are commercial restrictions, set by the operator. Deposit and wager limits you choose for yourself are a separate system with its own rules. See Commercial limits vs responsible gambling limits at sportsbooks.
What gets an account limited
Both regulators' data point the same way. In Massachusetts, players who consistently beat the closing line were more likely to have a lowered stake factor.[1] In Great Britain, 25.42% of all active customers were in profit, against 46.78% of restricted customers.[2] Beating the closing line is largely about getting better prices than the market settles at; you can measure the gap between your price and a fair one with the no-vig calculator.

Frequently asked questions
What does stake factor mean at a sportsbook?
It's a number a sportsbook assigns to an account to raise or lower the default maximum bet. A lowered stake factor means you can bet only a fraction of what a standard account could on the same market.
What is a 0.00 stake factor?
Effectively no betting at all. Great Britain's Gambling Commission groups a 0.00 stake factor with other ways of withdrawing betting facilities from an account.
How many accounts are limited?
In Great Britain's 2024 data, 4.31% of active accounts were restricted in some way. In Massachusetts, about 0.64% of accounts had a lowered stake factor on December 10, 2024. The two figures measure different things.
Are promotion restrictions a type of limit?
Bettors often describe losing access to promotions as being limited, but neither regulator dataset on this page measures promotion restrictions, so we can't say how common they are.
