Summary
Kalshi has signed an exclusive deal with the U.S. Per the report, which cites two sources familiar with the deal, the agreement goes into effect immediately and was not formally finalized until after the tournament's qualifying rounds concluded last week. The US Open, which is owned and operated by the USTA, was planning to consider prediction market partnerships for 2027 and beyond. Per one of the sources, the USTA is reportedly preventing other prediction market platforms from advertising both at the US Open venue and on television, including across ESPN's broadcasts of the tournament, marking an unusual aspect of the deal. Kalshi was not listed among the US Open's official partners as of Sunday afternoon.
