Narrative:

On climbout from mci we were given a climb to fl 320. Another opposite direction aircraft (other carrier) was also given the same clearance. Both the first officer (first officer) and I verified each altitude change during the climbout. The last clearance given to us was fl 320. ATC shorty after asked us to expedite through FL330 up to FL410 for opposite direction traffic at the same altitude. We stated we were only cleared to fl 320. ATC then cleared us to fl 410 and to be out of fl 330 in one minute. ATC then gave (other carrier) a heading 40 degrees to the right. We hurried our climb. We never received a TCAS alert. I believe ATC mistakenly gave us both the same clearance.
