They've been yammering about a financial transaction tax on the CME, CBOT and CBOE for years-- if they try that the exchanges will be out of Chicago so fast you'll be able to hear the sucking sound as money and jobs disappear. Chicago would really turn into Detroit in about 5 years after that.

They'll pay for a few years while making arrangements to leave. I wonder where they would move, though.

CBOE has already moved their servers (matching engine) to New Jersey to be nearer the stock exchanges.

CME has their servers (at least the backup) outside Chicago already, somewhere in the 'burbs, probably outside Crook County.

They could just go out to Lisle. I believe one of them had mentioned Indiana.

Now that the Texas economy has cooled off a little, Dallas would be a good place to move the exchanges.
