The first U.S. bitcoin futures will start trading next week, as dueling Chicago futures exchanges seek to cash in on surging investor interest in the digital currency.

Cboe Global Markets Inc.’s new bitcoin futures will go live at 5 p.m. Central time on Dec. 10, with the first full day of trading set for Dec. 11, the firm said Monday.

That gives Cboe a head start on CME Group Inc., its larger crosstown rival, which plans to launch its own bitcoin futures on Dec. 18. The U.S. Commodity Futures Trading Commission on Friday allowed both exchange operators to go forward with bitcoin futures.

Cboe is working with online brokerages to allow retail investors to start trading its bitcoin futures as soon as possible, a spokeswoman for the company said.

Bitcoin futures would allow traders to bet on rises and falls in the digital currency, similar to the way oil, corn or gold futures work. The emergence of bitcoin futures could make it easier for both Wall Street banks and small investors to trade bitcoin.
