The main reason for the hole: for installing flags, rarely used for nowadays, and to avoid a vacuum upon staking them on top of each other... I have even seen them stacked and put on poles mounted on the bumpers of large utility vehicles...

That's where you grab onto when you pull them off a stack.
Something else I found that's interesting.
SPECIFICATIONS FOR BID TRAFFIC CONES ASSORTED SIZES:
MATERIALS: The cone shaped section shall be of a flow-molded polyvinyl chloride. The
outside to be of a fluorescent red/orange and the inner liner to be white. The weighted
base shall also be of a polyvinyl chloride material and shall be fused to the unit. The
fluorescent red/orange to be compounded with ultraviolet absorbing material for longer life.
Top of cone to have a 1-1/4@ diameter hole, 1/16@ plus or minus, to accommodate a flag.
And then I found this unique use for a traffic cone.

Because if it had no hole it would be called a "traffic cylinder" , so the hole classifies it as a "cone". Hey! thats as good as all the other answers, right? LOL!

So when the cones are stacked on each other, the air trapped between the cones has an escape route.

So if when they're stacked they should get stuick together, it's a simple matter to unstick them! It also enables workers to move them without having to hug the whole thing; all they have to do is stick a few fingers into the top and pick them up.
Also, they're easier to manufacture as they are made from flat stock; that enables the manufactuirer to move them easier.

Good thinking about the suction cup part.
Only thing I can add is they're there so you can stick a traffic sign or pole into it.

Usually they are removed from the highway by workers who pick them up from moving platforms or vehicles. Without holes it would be hard to grab them in one motion.

To give them the ability to hold flags or markers, appended from the top, frequently used by road construction or maintenance crew personnel.

I'm sure pylons have holes so they can be used for stabilizing construction signs on poles and don't get stuck together, like a vacuum.

In case someone has to use one as a megaphone in an emergency.
