FanDuel Co-Founder Warns Kalshi May Follow Juul, Skillz Path

Nigel Eccles says Kalshi’s growth strategy mirrors that of Juul and Skillz, warning that prediction markets could face regulatory backlash.
FanDuel co-founder Nigel Eccles has publicly warned that prediction market platform Kalshi may be “traveling the same road” as companies like Juul and Skillz, suggesting the fast-growing exchange could face regulatory pushback if it continues expanding into sports.
Eccles made the comments in a recent social media post, where he compared Kalshi’s trajectory to companies that experienced explosive growth followed by intense legal and regulatory scrutiny.
It is clear to me that @kalshi is going down the same path as Juul, and if they don’t pull back it is going to have the same conclusion.

The Core Warning
Eccles’ central argument is that Kalshi’s strategy, expanding aggressively into high-profile consumer markets like sports, may trigger the same type of backlash seen in other industries.
He suggested that:
- Rapid consumer adoption can attract regulatory attention
- Blurring lines between finance and gambling increases legal risk
- High-visibility marketing may accelerate scrutiny
Juul, once valued at tens of billions of dollars, faced sweeping regulatory crackdowns over youth vaping concerns. Skillz, a mobile gaming competition platform, experienced market volatility and legal challenges tied to gambling classification debates.
Eccles implied that Kalshi could face similar headwinds if regulators determine sports contracts function more like betting than derivatives.
Why Kalshi Is Under Pressure
Kalshi operates as a federally regulated exchange under oversight from the Commodity Futures Trading Commission. The company allows users to trade contracts on the outcome of real-world events, including political, economic, and, more recently, sports events.
However, several state regulators have argued that:
- Sports event contracts resemble unlicensed gambling
- State gaming laws should apply
- Federal oversight does not eliminate state authority
Recent enforcement actions in Nevada and Massachusetts have intensified the debate over jurisdiction.
The Juul and Skillz Comparison
Eccles’ comparison centers on a common theme:
- Rapid adoption
- Cultural visibility
- Regulatory uncertainty
- Legal battles and reputational risk
Juul’s rapid growth prompted federal intervention and sweeping restrictions. Skillz faced ongoing legal challenges regarding whether its contests constituted gambling in certain jurisdictions.
By drawing parallels, Eccles appears to be cautioning that innovation in gray regulatory zones often invites aggressive enforcement.
Industry Reaction
Eccles’ comments come at a time when prediction markets are experiencing record trading volumes, particularly around marquee events like the Super Bowl.
Kalshi has argued that:
- Its contracts are financial instruments
- It complies fully with federal regulations
- It employs market surveillance safeguards
Supporters of prediction markets contend that comparing derivatives trading to vaping or mobile gaming oversimplifies the regulatory distinctions.
Critics argue that consumer perceptions, rather than legal classifications, ultimately shape political outcomes.
Broader Implications for Prediction Markets
The debate highlights larger questions facing the sector:
- Can sports-based event contracts coexist with state sports betting regimes?
- Will federal preemption withstand state-level legal challenges?
- Could public scrutiny reshape how prediction platforms market themselves?
As state regulators pursue enforcement and courts weigh jurisdictional questions, industry leaders are watching closely.
What This Means for Kalshi
Eccles’ warning does not signal immediate regulatory action but reflects a growing narrative risk.
If courts ultimately side with states over federal regulators:
- Kalshi may face fragmented licensing requirements
- National liquidity pools could be disrupted
- Business models may require structural changes
If federal authority prevails, prediction markets could continue expanding nationwide.
Bottom Line
Nigel Eccles’ comparison of Kalshi to Juul and Skillz underscores the mounting scrutiny surrounding sports-based prediction markets.
As legal battles intensify and trading volumes rise, the industry faces a pivotal question: will prediction markets mature into an accepted financial category, or trigger a regulatory reckoning akin to that of past high-growth disruptors?
