It's getting there... slowly. Single-stock futures already trade in Chicago, but for the time being it's just large caps. There is a chicken/egg problem. You need the volume to justify the listing and the listing isn't worthwhile to the exchange unless there's volume to support it.
There is an outfit that is supposedly trying to put together something in Belize that will let investors trade single-stock futures on any OTCBB or pink sheet. If it ever gets off the ground, you should be able to access it with any broker/dealer that'll let you trade penny stocks.
I think it's years away from reality, though.
