In December 2025, CNN and CNBC struck landmark deals with Kalshi, a leading prediction market. Since then, both networks have promoted Kalshi to viewers extensively, frequently vouching for its accuracy. The existence of a financial relationship between the networks and Kalshi, however, is disclosed to viewers inconsistently.
Since December CNBC has published 58 articles that do little more than advertise the existence of a Kalshi market related to a news event. The headlines include “Traders predict Michael Jackson hits top Spotify after biopic,” “Kalshi traders don’t see Hormuz traffic normal until July,” and “Traders say Karen Bass and Spencer Pratt will advance to runoff in high-profile LA mayoral race.” (Pratt did not advance.)
Since April, CNBC has employed a dedicated reporter to produce these articles. CNBC also maintains a page on its website featuring Kalshi prediction markets selected by CNBC editors, along with its web coverage.
Some of CNBC’s reporting about Kalshi includes the disclosure, “CNBC and Kalshi have a commercial relationship that includes customer acquisition and a minority investment.” This means CNBC is paid every time it can convert a viewer to a Kalshi user. As an investor, the network also benefits if Kalshi’s overall valuation increases. CNBC is also paid directly by Kalshi for using its data, according to The Wrap.
In at least 22 cases, however, CNBC has written about Kalshi and not disclosed its financial conflict. In recent weeks CNBC has more frequently failed to include its Kalshi disclosure, including two pieces on June 10, one each on June 11, June 15, June 16, and June 23, three pieces on June 26, and one each on July 1, and July 2.
On air, where CNBC promotes Kalshi nearly every day, disclosure is also spotty.
On June 26, during a Squawk Box interview with California Republican gubernatorial candidate Steve Hilton, host Andrew Ross Sorkin brought up the fact that Kalshi gives Hilton a 9.5% chance of winning the election. Producers then cut to a Kalshi graphic depicting those odds while a Kalshi QR code was displayed on the screen. The hosts never acknowledged CNBC’s financial relationship with Kalshi during the segment.
Similarly, during a news rundown on June 23, CNBC correspondent Contessa Brewer claimed that “prediction markets are hot, hot, hot” and mentioned that in recent days Kalshi and Polymarket “handled billions of dollars in trading volume” without disclosing CNBC’s business relationship with Kalshi.
CNBC’s Fast Money and Squawk Box each recently hosted Kalshi co-founder and CEO Tarek Mansour for extended soft-focus interviews. On June 24, for example, Squawk Box host Joe Kernen gave Mansour an open mic to portray Kalshi as a “pro-regulation company” that has kept its hands clean as “our competitors” have been mired in insider trading scandals.
