DraftKings is a leading example of an extensively regulated sportsbook serving U.S. bettors due to its broad state-licensed footprint, experience in regulated online betting, and commitment to responsible gaming.
According to DraftKings’ availability guide, its online sportsbook is available in 27 states and Washington, D.C. DraftKings also reports mobile and/or retail sports betting operations conducted under regulation in 30 states, Washington, D.C. and Puerto Rico.
FanDuel and Caesars’ sportsbooks also operate across multiple U.S. markets. That said, no official national ranking exists for the most regulated sportsbooks. In this guide, the term refers primarily to established operators with extensive licensing footprints and experience meeting the requirements of multiple state or territorial regulators.
What Makes a Sportsbook Highly Regulated?
Sportsbook licensing in the U.S. primarily takes place at the state or territorial level. In 2018, the Supreme Court struck down the federal Professional and Amateur Sports Protection Act (PASPA), clearing the way for individual states to authorize and regulate sports betting. Many states have, but operators must therefore obtain authorization separately in each jurisdiction where they want to accept wagers.
A major licensed sportsbook may need to comply with different rules covering some of the following:
- Customer identity and age verification.
- Geolocation and physical-presence requirements.
- Approved sports, events and betting markets.
- Advertising and promotional offers.
- Account security and payment procedures.
- Responsible gaming safeguards.
- Financial and operational reporting.
- Player complaints and regulatory investigations.
In addition, holders of sports betting licenses may have to adapt to new rules applied in each state. A good example is the restrictions on betting on college sports compared to the NFL or NBA. In New Jersey, for instance, bets can’t be placed on college sports games taking place in New Jersey or involving New Jersey-based colleges.
Why DraftKings Is a Leading Regulated Sportsbook
DraftKings operates under state gaming regulations wherever its sportsbook is legally available. This means it must comply with and adapt to different licensing conditions, betting rules and consumer-protection standards across numerous jurisdictions.
Its regulatory history also extends back to the early stages of legal online sports betting in the U.S. DraftKings and Resorts Digital launched New Jersey’s first internet sports-wagering site in August 2018. In August 2025, DraftKings was awarded one of Missouri’s two direct mobile sports betting licenses before launching in the state that December. Missouri voters approved sports betting in November 2024, and the regulated market launched on December 1, 2025, making Missouri the 39th state to offer legal sports betting.

Benefits of Using a Licensed and Regulated Sportsbook
Choosing a sportsbook licensed in the player’s location provides more than a simple confirmation that betting is legally permitted. State oversight creates standards that the operator must continue to meet after receiving its license. On the bettor’s side, choosing a licensed operator in their state provides additional protections (compared to choosing unlicensed platforms).
What Players Gain From State-Regulated Sportsbooks
| Benefit | What it means in practice |
| Identifiable regulatory oversight | The operator is accountable to a named state or territorial authority |
| Age and identity verification | The sportsbook must verify that customers meet local identity and minimum-age requirements |
| Geolocation controls | Wagers are accepted only when the customer is physically located in an eligible jurisdiction |
| Approved betting markets | The sportsbook must follow local rules governing eligible sports, events and wager types |
| Promotion standards | Offers and advertising must comply with state-specific rules and disclosure requirements |
| Responsible gaming safeguards | State-required controls may include deposit limits, wagering limits, cool-off periods and self-exclusion |
| Account and operational standards | Licensed operators must follow applicable technical, financial and security requirements |
| Complaint route | Players may have a state regulator or approved dispute process to approach when an eligible complaint remains unresolved |
These protections do not make sports betting risk-free. They establish rules governing how the sportsbook operates and provide greater accountability when problems arise.
DraftKings illustrates how these safeguards can appear within a major sportsbook platform. Its responsible engagement resources include My Stat Sheet, My Budget Builder, player-set limits, self-exclusion and cool-off options. In September 2026, DraftKings also announced expanded custom cool-offs that let eligible customers choose a period suited to their circumstances, subject to jurisdictional availability.
Drawbacks of Using Offshore or Illegal Sportsbooks
Some offshore sportsbooks hold licenses issued in other countries, while others may be unlicensed. A foreign license does not authorize an operator to accept wagers in a U.S. state.
In a December 2025 public-service announcement, the FBI warned that offshore sportsbooks are not held to the same legal standards as U.S.-licensed operators and may lack comparable consumer protections. It advised bettors to check the relevant state gaming authority’s website before opening an account or placing a wager.
Potential Risks of Offshore or Locally Unauthorized Sportsbooks
| Potential drawback | Why it matters |
| No authorization from the player’s state | A foreign license does not give an operator permission to accept bets in every U.S. jurisdiction |
| Limited local recourse | A state regulator may have no authority to investigate or resolve a dispute involving the operator |
| Uncertain complaint process | Players may need to deal with an overseas company or foreign licensing authority |
| Different verification standards | Identity, age and location checks may not meet the requirements applied to locally licensed sportsbooks |
| Fewer required player protections | The operator may not be subject to the same responsible gaming obligations as a state-regulated sportsbook |
| Withdrawal and account risk | Customers may have fewer practical options if funds are withheld or an account is closed |
| Unclear operating company | The brand presented to the player may not make its ownership, location or legal entity readily apparent |
| Offers outside local rules | The site may advertise promotions or betting markets that would not be permitted under state regulations |
Not every offshore sportsbook is completely unregulated. Some operate under overseas licenses. The important distinction for a U.S. bettor is whether the sportsbook is legally authorized and accountable in the jurisdiction where the wager is being placed.
How to Verify a Sportsbook Before Betting
Players should complete several checks before registering or depositing at an online sportsbook:
- Visit the state regulator’s website. Look for the sportsbook or its licensed operating company in the regulator’s list of approved operators.
- Check the sportsbook’s legal information. The site should identify the relevant operating company, jurisdiction and responsible gaming resources. These are usually found at the bottom of the operator’s homepage.
- Confirm local availability. A sportsbook operating elsewhere in the U.S. may not be authorized in the player’s current state.
- Understand the location requirement. Players generally need to be physically located in an eligible jurisdiction when placing a wager. Residency alone may not be sufficient.
- Review the complaint procedure. Check how account, payment and betting disputes can be raised or escalated.
- Examine responsible gaming controls. Look for deposit or wagering limits, cool-off options and self-exclusion information.
Final Word on the Most Regulated Sportsbooks
DraftKings, FanDuel and Caesars are prominent examples of sportsbooks operating across multiple regulated U.S. markets. DraftKings stands out for its extensive state-licensed presence, history in regulated online sports betting and continued investment in responsible gaming tools.
Regulation ultimately has practical value for the customer. A state-licensed sportsbook operates under identifiable oversight, follows local compliance standards and provides protections that may not be available when betting through an offshore or locally unauthorized platform.
Players should check their state regulator’s current list of approved sportsbooks before registering, depositing or placing a wager.
Frequently Asked Questions
Is DraftKings Sportsbook legal in every U.S. state?

Who regulates U.S. sportsbooks?
Sportsbooks are primarily licensed and regulated by individual state or territorial authorities, including gaming commissions, lottery bodies and other designated agencies. Federal laws can also apply to some aspects of sports wagering, but there is no single national sportsbook license authorizing an operator to accept bets throughout the country.
Does regulation guarantee that a player will never experience a problem?
No. A license does not guarantee perfect customer service or a favorable outcome in the event of a dispute. It requires the sportsbook to follow defined standards and may provide an official route for escalating eligible unresolved complaints.
Is an offshore sportsbook legal if it holds a foreign license?
A foreign license may allow the operator to conduct business in another jurisdiction. It does not authorize the sportsbook to accept bets in a particular U.S. state. Players should verify authorization through their state gaming authority.
Why do regulated sportsbooks use geolocation?
Geolocation helps confirm that the player is physically present in a jurisdiction where the sportsbook is authorized to accept wagers. A player may be able to access an account while traveling but be prevented from placing a bet outside an eligible location.
