Nasdaq Inc. will temporarily move some operations to Chicago, escalating a dispute with New Jersey over proposed taxes that would generate billions of dollars from high-speed trading at the stock exchange and its rival firms.

Nasdaq’s PSX exchange will move to Chicago the week of Oct. 26, according to a memo to traders to be released on Thursday. The move “will allow firms to gain additional confidence that they can react quickly in the event that Nasdaq decides to move the operation of all its market centers to its Chicago data center,” the company said.

New Jersey Governor Phil Murphy is considering a tax on stocks, options, futures and swaps trading that would go into effect for the 2022 budget year and could drum up $10 billion for the state. Wall Street giants, including the New York Stock Exchange, Citadel Securities and Virtu Financial Inc., have threatened to move operations from New Jersey if the tax is enacted.

Nasdaq is considering the move but wants it to be made in concert with other parts of the market such as broker-dealers, Tal Cohen, executive vice president for North American marketing, said in an interview on Bloomberg Television.
