Not all faster routes are about shipping, in fact IRL much shipping is done very slowly (on giant boats) in order to save money.
Or consider FedEx: People will pay 15 USD to ship a contract overnight, or 200 USD to ship a machine part overnight, instead of 50c in postage that might take three days. (or maybe 2 USD in postage for a machine part). Ten years before FedEx very few laymen would have believed that kind of multiplier, but people managing businesses, even relatively small ones, understand the value of time very well and would have paid even then.
One of the big advantages of a faster route is transporting very SMALL things, including immaterial things like information, sound and video. Also in the SMALL category can be people; and the smuggling of illicit things.
I would use the best of the new wormholes to provide a FedEx type of service for shipping everything from information to people. We can get it there faster, and more securely, guaranteed. If it fits in our cargo hold, we charge you by the cubic foot about 25 times as much as the normal routes.
Then you just have to find a way to keep them secret, keep from being followed, and keep somebody from shipping something that can report your route.
Another alternative would be to prove you HAVE such a route, and auction off the location to the highest bidder. Let giant corporations bid on it, set the minimum to something like a hundred million USD in modern day currency. It would be like (IRL) auctioning off an oil field to big oil. But you have many of them, and some may be worth billions to them, ones you could not exploit as well or protect as well as they could.
But of course, you don't have to auction off ALL of them, you can save the best of them, and use auction proceeds from the other to start your own big corporation that CAN protect your best routes, so you can compete against them.
