Iowa, a Midwestern state in the US, has a rich history behind its gambling industry. The gambling industry includes over 3.2 million people and has 19 retail casinos, legal sports betting, and a state-operated lottery among its features. The industry generates a great deal of revenue for state agencies to fund infrastructure projects and education programs. However, iGaming (online casinos) is still not permitted in Iowa. In January 2025, sports betting alone generated $289.7 million in handle (amount of wagers) and $26.2 million in gross gaming revenue (GGR), making that month the third highest in terms of total gross handle and gross revenue of any month ever, demonstrating growth in the aftermath of the pandemic. In 2026, Iowa will implement a new 3.8% state tax withholding for sports betting winnings, effective January 1, 2026. Additionally, Iowa will be working to suppress unlicensed offshore online sports betting sites through a cease-and-desist process starting in 2026. This report provides regulators, operators, and investors with information about the state of gambling in Iowa, showing that sports betting is the industry leader while iGaming remains excluded.

Regulatory Landscape
Gambling within Iowa is highly governed with an avid focus on retail casinos, sports wagering, and lottery, along with oversight from the Iowa Racing and Gaming Commission (IRGC). There are currently no online casinos (iGaming) allowed, while other states have moved forward with expansions, thus making Iowa one of the states with the most restrictive regulations on the style of gambling.
Overview of Existing Regulations
Under Chapter 99D of the Iowa Code, there are three specific forms of legal gambling available in Iowa:
(1) Parimutuel racing;
(2) Games of skill and chance (also called “sweepstakes”) under Chapter 99E; and
(3) Casino gambling, sports betting, and fantasy sports contests under Chapter 99F.
There are a total of 19 retail casinos in Iowa; they consist of both excursion boats and land-based or tribal casinos. Sports betting was legalized in Iowa in 2019; it can now be conducted in-person at one of the retail casinos or through an affiliated mobile application. The Iowa Lottery Authority operates an independent lottery that is separate from other forms of gambling; however, it does not permit slot machines or table games involving iGaming. There is currently no legal iGaming available in Iowa; offshore iGaming is also illegal.
Licensing Requirements and Regulatory Authorities
Types of Tempest licenses issued: casino ($45,000 initial application fee & background checks), sportsbook (partnering with casino/racetrack), mobile advance deposit wagering operators, vendor, or daily fantasy sports operator. There are currently 11 live sportsbooks (i.e., DraftKings using a casino skin). Other licensing requirements include: minimum capacity to operate financially; good character for all employees; geofencing; and 21 and over verification process.
- Casino license: Tied to facility approval.
- Sports vendor/operator: Casino affiliation mandatory.
- Compliance audits are ongoing.

| License Type | Requirements | Authority |
|---|---|---|
| Casino | $45K fee, background checks, facility | IRGC |
| Sportsbook | Casino partnership, geofencing | IRGC (11 active) |
| Vendors/DFS | Financial integrity, annual renewal | IRGC |
Taxation and Compliance Details
Payouts derived from taxation will follow this basic structure:
- Sports gambling: 6.75% GGR tax (retail/online)
- Casino: tiered 24-36% + local government fee
- Lottery: education funding
In 2026, casinos will withhold 3.8% state tax from any winnings over $5,000 (300X wager), and a flat rate of 24% remains unchanged.
Compliance: Responsible gambling (problem identification, referrals for treatment), anti-fraud, data security, and advertising disclosures. Underlying rules include no prop bets on college players in-state, thereby self-excluding oneself from the ability to engage in gaming activity.

| Tax Type | Rate/Details | Effective Date |

| Sports Betting GGR | 6.75% | Ongoing |
| Casino AGR | 24-36% tiered + local fees | Ongoing |

Upcoming Legislative Changes
In the 2026 session, House Bill (HB) 586 and Senate Bill (SB) 3040 will increase enforcement powers for the Iowa Racing and Gaming Commission (IRGC)—authority to issue a cease-and-desist order to unlicensed or unauthorized gaming (sweepstakes or offshore) and to enact an injunction against the same (e.g., prediction markets). Also includes broadening the application of the lifetime ban on being allowed to participate in sports or advanced deposit wagering on horse races. Senate Bill (SB) 3002 establishes limits on simulcasting dog racing (July 2027). No funding for iGaming; consistent with the sweepstakes crackdown.

Competitive Landscape
Iowa boasts 19 retail casinos, 22+ licensed sportsbooks (through casino skins), and a state lottery that creates a highly competitive atmosphere for gambling, particularly with the introduction of sports betting.

Sportsbooks (22 active, 2026): International giants—DraftKings, FanDuel (Flutter), BetMGM (MGM), Caesars, bet365, Fanatics, BetRivers (Rush St.), Hard Rock Bet, Bally Bet, ESPN BET (Penn), others (Sporttrade, DRF, Circa, ClutchBet, Tipico, Betway, Fubo, theScore, BetFred, Elite, Q).

| DraftKings | 30-40% | $108M Sep 2024 handle leader |
| FanDuel | 20-30% | Strong mobile promo |
| BetMGM/Caesars | 15-20% | Casino-backed |
Partnerships and Strategic Alliances
Every sportsbook has to partner with a casino or racetrack (2 total skins max per license, or 38 total). For example, DraftKings has several skins, including Isle, FanDuel has Betfair via Diamond Jo, Fanatics has its skin through Catfish Bend, Sporttrade had Wild Rose, and Bally has a skin through one of their casinos, and PointsBet was originally through Catfish Bend, but has now evolved. While casinos want to make money off of these skins from revenue share agreements (i.e., Caesars-Horseshoe), tribes are selective about their partnerships (i.e., with the Meskwaki).
- Expands via mergers (Penn-ESPN BET).
- Focus: tech integration, promos.

Table 8: Player Preferences and Methods

| Payments | ACH/debit, Play+, cage cash; 24hr payouts |
| Demographics | Males 21-44 sports; 70% past-year gamblers |
| Tech Trends | Mobile apps (50% bets), live betting |
Payment Methods and Technological Trends
Sportsbooks support debit/ACH (Visa/Mastercard, Iowa-only, no credit), e-wallets (PayPal select states, Skrill NJ), Play+, cash at cages, and online banking (BetRivers fast). Payouts 24hrs.
Trends: Mobile apps boom (50% bets), geofencing; KYC/AML/RG mandatory 2025+. No crypto mainstream.
Social and Cultural Influences on iGaming
The Midwest’s values serve as a filter against excesses: 44% of gamblers fee, on balance, there are more harms than benefits; however, those who gamble in the past year, at least 70% will show some measure of acceptance. So, initially, activities like playing cards with family/friends or lottery games have been mainstreamed; stigma surrounding problem gambling drives individuals to self-exclude. The iGaming market is heavily regulated; consequently, online gambling sites that operate outside US jurisdictions and/or through sweepstakes are attractive to younger, technology-oriented gamblers despite risks.
Opportunities & Challenges
The potential for growing revenue through sports betting expansion (10%+ Year on Year) and through digital lottery products is significant; iGaming may add $100M+ in GGR compared to similar states based on studies, thus attracting operators/investors. New entrants are possible through partnerships and innovations, such as virtual reality betting or esports, which are still significant opportunities.
Challenges: limited the ability of iGaming to pivot online casinos due to its ban; offshore illegally draining revenue (and associated fraud risks). The costs associated with regulatory hurdles (Licensing, 6.75% tax, 2026 withholding) will increase. A highly competitive marketplace (of 11 sportsbooks) will limit profits. Operational challenges exist (e.g., geofencing compliance, responsible gaming requirements).
| Factor | Opportunities | Challenges |
|---|---|---|
| Regulation | Enforcement bills stabilize the market | No iGaming path |
| Tech | Mobile/esports growth | Compliance costs |
| Entry | Casino partnerships | Saturation |
Conclusion & Recommendations
Sports betting ($20+MM/month GGR) & casinos will support IA’s gambling market with tax revenue generated for infrastructure projects in a stable regulatory environment. Lack of iGaming has impacted the total revenue potential. The IRGC will play a crucial role in compliance/enforcement and determining potential tax revenue shifts.
Recommendations for operators include pursuing casino agreements to gain access to sports betting; lobbying for iGaming using statistics (i.e., live/dead, i.e., $39B U.S. iGaming) as the basis of their arguments; and investors targeting new retail developments and providing compliance support and assistance in development.
Outlook: Continued growth; no iGaming anticipated until 2027 due to legislation needed.
