The Commodity Futures Trading Commission is reviewing prediction betting platforms' mention markets, and prediction market Kalshi has taken down its sports-related mention exchanges in response.
Imagine a game where people bet on what words a famous person will say in a speech. This game is called a 'mention market.' Some people think it's a good idea, but others think it's too easy to cheat. Now, a group called the CFTC is looking into whether this game is fair and safe.
Analysis
CFTC Review of Mention Markets
The Commodity Futures Trading Commission (CFTC) is conducting an internal review of prediction betting platforms' mention markets, people familiar with the situation told CNBC. Mention markets are made up of contracts where traders speculate on whether specific words will be used in a speech, a corporate earnings call with analysts and investors, or a television broadcast.
The CFTC first alerted platform Kalshi of the review several weeks ago. The platform removed sports-related mention markets around the same time the CFTC alerted the company, the person said. NPR first reported an inquiry into mention markets late Thursday.
It's unclear if the inquiry only applies to sports-related mention markets or all of them regardless of topic. Kalshi and the CFTC declined to comment.
Scrutiny of Prediction Markets
Mention markets are some of prediction markets' most scrutinized offerings. Critics view them as easily manipulable by one individual, and some platforms don't offer them. Mention markets saw about $3.3 million in trading volume on Kalshi last month, according to Dune Analytics, far behind larger markets such as those devoted to cryptocurrencies.
In July, the CFTC said it was investigating a former teleprompter operator for President Donald Trump who allegedly made $90,000 in profits on Kalshi betting on the content of Trump's speeches. Coinbase CEO Brian Armstrong last December rattled off a series of random words at the end of an earnings call to demonstrate how easily prediction market wagers can be manipulated.
Proponents of Mention Markets
Proponents of mention markets argue words by powerful individuals have the power to move billions of dollars of money across traditional markets, making it useful to have predictive power to them. "The suggestion that Mentions Markets create 'new' manipulation incentives is, on close inspection, overstated," Kalshi head of market operations Arjun Sawai wrote in a letter to the CFTC as part of a public comment period last month.
"They merely add a marginal, regulated, transparent, position-limited, surveilled increment to a vastly larger existing incentive structure."
Key points
- The CFTC is reviewing prediction betting platforms' mention markets.
- Kalshi has taken down its sports-related mention exchanges in response.
- Polymarket does not have mention markets on its CFTC-regulated U.S. exchange.
- The CFTC increased scrutiny of prediction market platforms in recent weeks.
- A Washington state judge blocked several of Kalshi's markets from operating there, including mention markets.
If the CFTC review leads to clearer guidelines for prediction markets, it could help the industry grow and become more trustworthy. This could also lead to more innovation in the field, as companies would have a better understanding of what is allowed and what is not.
If the CFTC review leads to overly restrictive regulations, it could stifle innovation in the prediction market industry and make it harder for companies to operate. This could also lead to a loss of trust in the industry, making it harder for companies to attract investors and customers.
