On February 10th, the CEO of Kalshi went on CNBC to celebrate a milestone: over $1 billion in Super Bowl betting volume.
What happened next turned a victory lap into one of the most revealing interviews a prediction market CEO has ever given and raised serious questions about insider trading in prediction markets.
Let’s break down what happened and why it matters.
Key Takeaways
- The regulated prediction market platform reported over $1 billion in Super Bowl trading volume, including $500 million on the game outcome and $100 million on halftime show props.
- Unlike corporate executives in stock markets, entertainers and production teams have no legal obligation to keep information private, creating gray areas around what qualifies as material nonpublic information.
- Blockchain analysis of 1.7 million Polymarket addresses found that 70 percent of users lost money, while just 0.04 percent captured 70 percent of total profits, suggesting significant concentration among a small group of traders.
- Although Kalshi is regulated by the CFTC, state regulators have challenged prediction markets, creating legal uncertainty about how these platforms should be classified and monitored.
What Are Prediction Markets?
Prediction markets are platforms where users trade contracts based on the outcome of real-world events. Instead of betting against a sportsbook, participants trade based on probabilities.
In the United States, Kalshi is one of the largest regulated prediction market platforms. For the Super Bowl, the numbers were staggering:
Kalshi CEO Tarek Mansour proudly declared the company the biggest brand of the Super Bowl without running a Super Bowl ad.
Then CNBC started asking uncomfortable questions.
The Big Question: Is Insider Trading Possible on Prediction Markets?
One CNBC host posed a simple hypothetical:
If you were a dancer in Bad Bunny’s halftime show and knew the opening song ahead of time, and then placed a bet, wouldn’t that be insider trading?
That question strikes at the core issue surrounding prediction markets.
How Insider Trading Works in the Stock Market
In traditional financial markets:
- Corporate executives are legally required to keep material nonpublic information private
- Trading on that information is illegal
- The SEC monitors and enforces violations aggressively
Kalshi is regulated by the Commodity Futures Trading Commission, or CFTC, and Mansour argued they have the same enforcement mechanisms as major exchanges like the NYSE or Nasdaq.
But here is where things get complicated.
The Problem: What Counts as Material Nonpublic Information?
In stock markets, insider trading laws apply because executives have a legal obligation to protect confidential information.
In entertainment, the situation is very different.
- A halftime performer’s setlist is not legally protected
- A dancer can post it on Instagram without breaking the law
- There is no statutory obligation to keep it confidential
So when Kalshi creates a $100 million market around that information, does it suddenly become material?
CNBC host Becky Quick challenged the CEO’s logic directly, arguing that the responsibility is not on performers to keep information secret simply because a betting platform creates a market around it.
That is the key distinction. Kalshi did not create the information. They created a market around it.
Were There Signs of Insider Trading?
While there is no confirmed wrongdoing, several reports raised eyebrows:
- A brand new account created less than 24 hours before the Super Bowl allegedly bet exclusively on halftime props and reportedly hit every single one
- Accounts wagered hundreds of thousands of dollars on Lady Gaga appearing before it was publicly announced
- Betting influencers claimed they had inside sources, and betting odds shifted immediately after their posts
It is important to note that many of these reports center around Polymarket, which has offshore operations allowing anonymous participation. Kalshi requires identity verification under United States regulations. Still, the optics are difficult to ignore.
The Giannis Antetokounmpo Deal and Timing Concerns
Just days after the NBA trade deadline, two-time MVP Giannis Antetokounmpo announced he had become a shareholder in Kalshi.
Shortly before the announcement, Kalshi hosted a market on whether Giannis would be traded. That market generated $23 million in volume.5
There is no evidence of wrongdoing. Kalshi says Giannis is prohibited from trading NBA markets. But in an era where multiple NBA players have faced betting suspensions, the timing raised concerns.
ESPN’s Dan Wetzel wrote that the deal does the NBA no favors.
The Data Raises More Questions
A blockchain analysis of 1.7 million Polymarket addresses revealed:
Are those 700 accounts simply better researchers? Or do some participants have information advantages? That is the uncomfortable question that prediction markets cannot fully answer.
Are Prediction Markets Properly Regulated?
Kalshi is regulated by the CFTC, which traditionally oversees commodities like oil, wheat, and soybeans.
Entertainment integrity, celebrity appearances, and halftime show setlists are new territory.
At the same time:
- Nevada and New Jersey issued cease and desist letters against Kalshi
- Legal battles have resulted in mixed outcomes
- Even DraftKings and FanDuel prediction style markets are not available in all 50 states
Prediction markets exist in a gray zone. They are not quite stock exchanges and not quite sportsbooks. Regulatory gray zones often create enforcement gaps.
Are Prediction Markets Designed to Encourage Insider Information?
Prediction markets were built to aggregate information. The best information often comes from people closest to the event. Some economists argue that insider participation makes markets more accurate.
But there is a difference between informational efficiency and fairness.
When betting on a halftime show song, a celebrity appearance, or an NBA trade, are you competing against other fans or someone who was literally at rehearsal?
That is what the CNBC interview exposed. Even the CEO struggled to clearly define the line.
Should Retail Users Be Concerned?
Prediction markets can feel empowering. They create the impression that research and awareness can provide an edge. But if a small fraction of users capture the majority of profits, it raises a critical question.
Is the edge coming from analysis or access?
Until regulators clarify how insider information is defined in non-traditional markets, the controversy is unlikely to disappear.
Final Thoughts
The Super Bowl interview revealed something bigger than record betting volume.
It exposed a structural tension at the heart of prediction markets:
- They rely on information
- The best information is not always public
- The rules around that information remain unclear
Are prediction markets the future of forecasting or a platform that rewards informational advantages? The answer remains uncertain.
