The Gambling Wire: Kalshi Enters Tribal Prediction Markets as Polymarket, DraftKings Face Scrutiny
Overview: A Week of High-Stakes Developments in Prediction Markets and Sports Betting
The world of prediction markets and sports betting saw a whirlwind of activity over the past week, with landmark legal rulings, explosive investigative reports, and a first-of-its-kind tribal partnership reshaping the landscape. From a Native American tribe launching a Kalshi-powered prediction market to federal probes into Polymarket and DraftKings, the industry is facing unprecedented scrutiny and opportunity. This guide breaks down the key events, their implications, and what they mean for operators, regulators, and bettors alike.
The Big Story: Tunica-Biloxi Tribe Launches First Tribal Prediction Market
A Historic Move in Tribal Gaming
The Tunica-Biloxi Tribe of Louisiana has become the first sovereign Tribal nation to launch a prediction-market app, marking a significant shift in how Native American communities engage with this emerging sector. The Tribe launched SaltTrade Derivatives, a platform that will use Kalshi’s exchange and infrastructure to offer event contracts. Under the partnership:
- SaltTrade will manage the app, branding, marketing, and customer experience.
- Kalshi will provide matching, clearing, custody, and surveillance services.
This move stands in stark contrast to the approach taken by many other Tribal governments and organizations, which have actively challenged sports event contracts in court.
Context: The Legal Battle Behind the Launch
The Tunica-Biloxi announcement came just two days after a landmark ruling from the Ninth Circuit Court of Appeals. The court sided with the Blue Lake Rancheria and Chicken Ranch Rancheria, finding that these tribes were likely to succeed on their claim that sports-event contracts constitute Class III gaming under the Indian Gaming Regulatory Act (IGRA) when entered from Tribal lands. This ruling was a significant victory for tribes seeking to classify prediction markets as regulated gambling rather than unregulated financial products.
Earlier that same week, leaders from 17 Tribal organizations sent a letter to CFTC Chairman Michael S. Selig, arguing that the agency’s rulemaking threatens Tribal gaming and sovereignty. The letter warned that allowing prediction markets to operate without tribal oversight could undermine the regulatory framework established by IGRA.
Why Tunica-Biloxi Went a Different Route
Rather than fighting Kalshi in court, the Tunica-Biloxi Tribe has positioned prediction markets as an economic development opportunity. In announcing the partnership, Kalshi CEO Tarek Mansour argued that “prediction markets and Tribal economic development don’t have to be at odds.” He emphasized that the structure gives the Tribal-owned business access to a federally regulated exchange with nationwide liquidity—a resource that could be particularly meaningful for tribes that “haven’t benefited equally from the existing gaming economy.”
Related Legal Developments
- Novig v. New York: A day before the Tunica-Biloxi announcement, Tribal organizations were granted permission to file an amicus brief supporting New York regulators in this case. Novig is seeking a preliminary injunction against state enforcement of gambling laws targeting prediction markets.
- Tribal Unity vs. Division: The contrasting approaches highlight a growing rift within Tribal gaming communities. While some tribes see prediction markets as a threat to their sovereignty and revenue, others view them as a new frontier for economic growth.
Investigation Spotlight: Polymarket’s Fraud and Compliance Crisis
The Wall Street Journal Report
A damning investigation by The Wall Street Journal revealed that Polymarket’s U.S. operations struggled with significant fraud, compliance, and product-control problems as the company pushed for rapid growth. Key findings include:
- Fraudulent deposits: In February, one of the company’s payment processors flagged more than 80% of the deposits it handled as fraudulent. Fraudsters allegedly linked stolen debit cards to Polymarket accounts and attempted to move at least $10 million.
- Second security breach: In July, an engineering flaw allowed attackers to use stolen personal information to access nearly 500 user accounts and their linked payment methods. Polymarket said it would cover customer losses.
- Internal warnings ignored: Current and former employees told the Journal that they raised concerns with CEO Shayne Coplan, but he pushed the company to keep growing and address potential regulatory penalties later.
- CFTC investigation: The Commodity Futures Trading Commission (CFTC) is investigating Polymarket, and the regulator has instructed employees to preserve records related to the fraud attack and other matters.
What This Means for Users and Regulators
The Polymarket case underscores the risks of unregulated or loosely regulated prediction markets. For users, the security breaches highlight the importance of:
- Using strong, unique passwords and enabling two-factor authentication.
- Monitoring account activity for unauthorized transactions.
- Avoiding platforms with a history of fraud or compliance failures.
For regulators, the report provides ammunition for stricter oversight. The CFTC’s investigation could lead to fines, operational restrictions, or even a shutdown of Polymarket’s U.S. operations.
Investigation Spotlight: DraftKings and the Ethics of AI-Driven Marketing
The New York Times Report
An investigation by The New York Times found that DraftKings used machine-learning models to identify customers likely to lose more after receiving promotions—but declined to deploy similar tools to identify users at risk of problem gambling. Key details:
- Casino model: One online casino AI model scored customers based on how much they were likely to lose per promotion.
- Sportsbook expansion: DraftKings later developed similar techniques for its sportsbook users.
- Abandoned risk model: Employees built a model designed to identify gambling-related risk before customers reached an intervention threshold, but the project was shelved.
DraftKings’ Response
Lori Kalani, DraftKings’ Chief Responsible Gaming Officer, said the company determined that predictive risk scoring was “insufficiently evidence-based” and that its existing monitoring system was more appropriate. DraftKings also disputed that promotions target customers based on losses, saying they are directed toward “sustained, engaged users.”
Ethical Implications
The Times report raises serious questions about the ethics of using AI to maximize revenue from vulnerable customers while ignoring tools that could protect them. For the industry, the fallout could include:
- Increased regulatory scrutiny: States may require operators to implement responsible gaming tools before deploying profit-maximizing AI.
- Reputational damage: DraftKings may face backlash from customers, investors, and lawmakers.
- Potential lawsuits: The findings could fuel litigation from affected customers or advocacy groups.
U.S. Legal Developments: Kalshi Faces Setbacks and Delays
Washington State: Kalshi Loses Reconsideration Bid
King County Superior Court Judge John McHale denied Kalshi’s motion to reconsider an amended preliminary injunction restricting its event-contract business in Washington state. Kalshi had argued, in part, that other prediction-market operators continued to operate in the state while its Ninth Circuit appeal remained pending. The injunction remains in place as the appeal continues.
This is a significant setback for Kalshi, which seeks to operate in all 50 states. The ruling signals that Washington courts are taking a firm stance against prediction markets that may violate state gambling laws.
New Jersey: Kalshi Seeks More Time for Supreme Court Response
Kalshi has asked the U.S. Supreme Court for an additional 30 days to respond to New Jersey regulators’ petition for review. Its brief in opposition is currently due Oct. 8, with Kalshi seeking an extension through Nov. 9.
New Jersey filed its petition on Sept. 2, after the Third Circuit ruled in April that Kalshi’s sports contracts qualify as swaps and that federal commodities law preempts New Jersey’s gambling rules. The Supreme Court’s decision to hear (or not hear) the case could have sweeping implications for the entire prediction-markets industry.
Sports Betting Update: Clase Gambling Case and State Developments
Former MLB Pitcher Emmanuel Clase Accused of Betting Scheme
Federal prosecutors identified 18 pitches they allege former Cleveland Guardians closer Emmanuel Clase manipulated as part of a sports-betting scheme, including one during the 2024 postseason, according to ESPN. Clase and fellow pitcher Luis Ortiz are accused of:
- Providing advance information to bettors.
- Intentionally throwing certain pitches outside the strike zone.
Both have denied wrongdoing. The case highlights the ongoing challenge of preventing insider information from influencing sports betting markets.
iGaming Legalization Push: iDEA Roundtable
Lawmakers from Ohio, Virginia, and Massachusetts discussed online casino legalization during an iDevelopment and Economic Association (iDEA) roundtable focused on revenue, cannibalization, and consumer protections.
- Ohio Rep. Brian Stewart: Projections suggest iGaming could eventually generate up to $400 million annually for Ohio. He discussed limiting licenses to existing casinos and racinos while steering promotional benefits toward retail properties.
- Virginia Sen. Jeremy McPike: Cautioned against aggressive revenue assumptions and cited concerns about cannibalization of retail gambling.
- Massachusetts Rep. David Muradian: Argued that regulation could move consumers away from offshore or unregulated sites and generate tax revenue.
Key takeaways for the industry:
- iGaming legalization is gaining bipartisan support but faces hurdles from brick-and-mortar interests.
- States are watching each other’s models to determine the best regulatory approach.
Stories to Watch This Week
Prediction-Market Litigation
Several key hearings are scheduled:
- Sept. 23: Four tribes in New Mexico will ask a federal judge to preliminarily block Kalshi while the court also considers Kalshi’s motion to dismiss.
- Sept. 24: A California district court will hold a status conference and hear two tribes’ pending motion to amend their complaint and add another party. The preliminary-injunction dispute returns to the lower court after the Ninth Circuit’s remand.
- Sept. 24: Novig’s reply in support of its preliminary-injunction request against New York regulators is due.
States to Watch: Missouri, Kentucky, Connecticut, New York
- Missouri: Attorney General Catherine Hanaway told a local outlet that her office is preparing to issue cease-and-desist letters to prediction-market companies.
- Kentucky: Hanaway also said Kentucky regulators were close to some form of settlement with prediction-market operators. In June, Kentucky sued Kalshi and Polymarket, after which the CFTC sued the state. No public details of any settlement have emerged.
- Connecticut: Reports suggest that some prediction markets have complied with Connecticut’s cease-and-desist letters, while Underdog sued the state.
- New York: Developments could emerge at any point as regulators continue to monitor the sector.
Other Key Events
- Sept. 24: The Indiana Gaming Commission meets and is scheduled to consider the NCAA’s request to prohibit college-athlete proposition bets. The commission had been expected to take up the issue in June but postponed the discussion.
- August sports betting figures: Expect more state-by-state data releases this week. Massachusetts, Tennessee, Connecticut, Louisiana, and North Carolina released their July figures between Aug. 20 and 28.
What This Means for the Future
The past week’s events signal a turning point for prediction markets and sports betting. Key trends to watch:
- Tribal gaming sovereignty vs. innovation: The Tunica-Biloxi partnership shows that some tribes are embracing prediction markets, but legal battles will determine whether they can do so without federal or state interference.
- Regulatory crackdowns: The Polymarket and DraftKings investigations suggest that regulators are taking a harder look at operator practices, from fraud prevention to responsible gaming.
- State-by-state patchwork: With some states issuing cease-and-desist letters and others exploring iGaming legalization, the legal landscape remains fragmented and unpredictable.
- Supreme Court involvement: The New Jersey case could set a national precedent for whether prediction markets are commodities or gambling, reshaping the industry for years to come.
For operators, staying ahead of these developments will require robust compliance systems, transparent marketing practices, and engagement with tribal and state regulators. For consumers, the message is clear: proceed with caution, and always verify the legality and security of any platform you use.
