Kalshi spends over $1m lobbying as prediction market dispute intensifies

Kalshi accused Washington State authorities of selectively enforcing gambling rules against its platform while leaving competitors, including Polymarket, unchallenged, according to a letter sent to the Washington State Gambling Commission. Washington’s attorney general’s office rejected the accusation and said its action was based partly on Kalshi’s size in the state. A King County judge had issued interim restrictions on Kalshi’s event contracts in August, while allowing contracts in several other categories to continue.
