The prediction market business has recently begun to enter the sponsorship landscape of major sports events. According to The Block, Kalshi has become the exclusive prediction market partner of the US Open.
The report pointed out that the agreement comes with an exclusivity clause: rival prediction market platforms are prohibited from advertising at the event and in ESPN broadcasts. In other words, as long as the audience watches the US Open broadcast in front of the TV or enters the event venue, the only prediction market brand that can be seen is Kalshi.
The signing amount, term and other details of the current agreement have not yet been made public.
