There is a chance your flight would be from Terminal 2, which is one stop sooner. Then through security (queues are long sometimes), and depending on what gate your flight is from, it might be a short walk, or a fairly long walk through an underground tunnel, possibly followed by another moderately long walk through the terminal.
It is possible to make it in 92 minutes, but it is also possible not to
If it is extremely important for you to make the final destination on time, I'd be at least a little worried.
My personal record at ORD is arriving from ARN at 11.58 (22 min ahead of schedule) and being through Terminal 1 security at 12.30, 32 minutes after landing, 12 mintes after scheduled landing. Priority tagged luggage, and seated in C meant that I was first off the plane, and first in immigration lane.
But I would also rebook if at all possible to later flight. If not: check that your travel insurance covers the hotel costs for an extra night in Chicago. Less than two hours is risky for all US INT/DOM connections, and I would feel better with three. YMMV
