Kalshi Disputes Gambling Label as LaLiga Partners With Polymarket

Kalshi, a US-based prediction market operator, has classified itself as a “gambling” firm in a United States Patent and Trademark Office (USPTO) filing, contradicting its public lobbying to be regulated as a financial asset. This internal admission coincides with competitor Polymarket securing massive partnerships with Major League Baseball (MLB) and LaLiga to expand its US presence.

The collision between financial derivatives and sports betting has reached a critical inflection point. For years, prediction markets have attempted to carve out a niche as sophisticated financial tools, operating under the jurisdiction of the Commodity Futures Trading Commission (CFTC). By framing their contracts as financial assets rather than wagers, these platforms have bypassed the restrictive web of state-by-state gambling laws, allowing them to operate across all 50 states. However, the distinction between a “prediction contract” and a “bet” is becoming an increasingly thin line that the US government is now scrutinizing.

The current friction centers on a strategic misstep in Kalshi’s trademark application. While the company has spent significant resources lobbying against a “gambling” designation, its filing with the USPTO utilized specific betting classifications. This creates a paradox: the company publicly argues it is a financial exchange while privately seeking trademark protection in categories reserved for gambling operators. Kalshi defends the move as “intentionally broad,” claiming the filing was designed to protect the brand from activity in adjacent markets. This defense clashes directly with USPTO guidance, which mandates that any submission failing to reflect the actual nature of the business is unacceptable.

This regulatory vulnerability is a gift to traditional sportsbook operators and a risk for Kalshi’s operational stability. When a company’s internal legal filings contradict its public regulatory stance, it opens the door for aggressive litigation. This is already manifesting in the courts; as of December 29, 2025, Kalshi is embroiled in a nationwide class action lawsuit alleging the platform has been facilitating illegal sports betting. For a company attempting to maintain a “financial” veneer, being labeled a gambling operation in a federal filing provides ammunition for plaintiffs arguing that the service is, in fact, an unlicensed sportsbook.

While Kalshi fights a defensive war on the regulatory front, Polymarket is playing an aggressive offensive game. The shift in momentum is evident in the boardroom, where Polymarket has successfully inked massive deals with global sports powerhouses like LaLiga and MLB. These partnerships signal a shift in how professional leagues view prediction markets—not as rogue financial experiments, but as legitimate engagement tools. As Polymarket embeds itself into the infrastructure of professional sports, it creates a halo effect that attracts more users and further marginalizes Kalshi’s struggle for identity.

The battle for legitimacy extends beyond trademark filings and league partnerships into the realm of information integrity. Both Kalshi and Polymarket have come under fire for their promotional tactics on social media, specifically their reliance on “insider” accounts to drive market activity. Reports from late December 2025 revealed a pattern of partnering with X accounts that claimed credentialed access to sports information. One prominent example, an account under the name Scott Hughes, claimed to be a credentialed men’s basketball reporter while repeatedly disseminating false information. This reliance on “insider” personas suggests a desperation to manufacture volatility and volume, blurring the line between a transparent market and a manipulated betting pool.

The financial implications of this shift are staggering. If prediction markets are forced to move from CFTC oversight to state gambling regulations, the cost of compliance will skyrocket. They would be forced to secure individual licenses in every state, pay state-level gaming taxes, and adhere to strict KYC (Know Your Customer) and AML (Anti-Money Laundering) protocols that are far more rigid than those in the derivatives market. Businesses facing this transition must secure trademark and intellectual property lawyers to clean up conflicting filings and regulatory compliance experts to navigate the pivot from federal to state oversight.

Market Positioning: Kalshi vs. Polymarket

The divergence in strategy between the two leading platforms is highlighted in the table below, illustrating the gap between regulatory aspiration and commercial reality.

The long-term viability of these platforms depends on whether they can survive the transition from the “Wild West” phase of prediction markets to a regulated corporate era. The partnerships secured by Polymarket suggest a blueprint for survival: integrate directly with the leagues to gain institutional legitimacy. Conversely, Kalshi’s trajectory suggests a company caught between two worlds—too “gambling” for the CFTC and too “financial” for the sportsbooks.

As the industry evolves, the ripple effects will be felt beyond the platforms. The integration of prediction markets into leagues like MLB and LaLiga will likely force a rewrite of Collective Bargaining Agreements (CBAs) regarding athlete involvement in betting markets. This creates a massive demand for sports partnership consultants who can bridge the gap between league governance and new-age betting technology.

The “intentionally broad” trademark strategy may have been intended as a shield, but it has instead grow a target. As congressional scrutiny intensifies over state gambling revenues and suspected insider trading, the industry is moving toward a reckoning. The platforms that survive will be those that stop pretending they aren’t gambling and start building the legal and ethical infrastructure to support it. For the professional athlete and the league executive, the era of “prediction markets” is simply a new name for an old game, played with higher stakes and more complex lawyers.

Whether you are a franchise owner navigating these new revenue streams or an athlete managing your personal brand amidst these volatile markets, the need for vetted professional guidance is paramount.
