Cardi B’s brief Super Bowl halftime appearance triggers a CFTC complaint after prediction markets clash on whether she performed

A brief onstage appearance by Grammy-winning rapper Cardi B during the Super Bowl LVIII halftime show has triggered a formal complaint to the Commodity Futures Trading Commission (CFTC), highlighting disputes in the growing prediction market sector.

The controversy stems from whether Cardi B’s cameo qualified as a “performance,” leaving major platforms Kalshi and Polymarket at odds over how to settle millions of dollars in wagers.

Prediction markets allow users to trade event contracts framed as yes-or-no outcomes, with contract prices reflecting the probability of an event occurring.

Kalshi’s “Who will perform at the Big Game?” market attracted more than $47.3 million in wagers this year, while Polymarket saw over $10 million in volume.

During the halftime show, Cardi B appeared alongside Karol G, Young Miko, Jessica Alba, and Pedro Pascal, dancing amid Ricky Martin and Lady Gaga’s performances.

Her lack of vocal contribution sparked debate over whether her presence constituted a qualifying performance.

Kalshi responded by halting trading and refunding users, citing the “ambiguity over whether or not Cardi B’s attendance…constituted a qualifying ‘performance.’”

Polymarket, in contrast, resolved its contract in favour of “Yes,” prompting challenges from users seeking clarification.

The dispute escalated when a Kalshi trader filed a CFTC complaint, claiming the platform violated the Commodity Exchange Act in its settlement process and seeking $3,700 in damages.

The case was first reported by Event Horizon newsletter and Front Office Sports.

The controversy coincides with a record-setting Super Bowl weekend for Kalshi, which reported over $1 billion in total trading volume on game day, up more than 2,700% from last year.

Season-long trading on Super Bowl winner futures reached $828.6 million, a 2,000% increase from 2025.

Kalshi co-founder Luana Lopes Lara acknowledged deposit-processing issues caused by unprecedented traffic, assuring users that affected accounts were reimbursed.

Other platforms, including Robinhood Markets, have also reported robust growth, with CEO Vlad Tenev describing prediction markets as entering a “super cycle” that could eventually drive trillions in annual volume.
