I doubt this is unusual, and presume JP Morgan is big enough to handle the change of status, either by managing security releases in-house or relying on third-party releases (say, Anaconda). When I retired from Citadel recently, most Python was still 2.7 (though the group I worked in was well on the way to converting to 3.x, and no new applications were written against 2.7). Bank of America has an enterprise-wide system called Quartz. I wouldn't be surprised if it was still running Python 2.7 (though I don't know for sure).
