As an Engineer; I wouldn't repair as it would not be as strong and prone to more cracking since an aluminum alloy.
They have to machine all material away from crack and find end where you need to drill hole. then it has to be welded up properly and possibly heat treated and then machined.
In mean time the wheel can warp and get out of round due to adding heat from welding.
Now I am sure peeps and businesses out there say they can repair... but I am more safety prone for rotating structures.

As for who can do it, check with a local tire shop, they usually run into those all the time and can recommend a local shop. Might not be worth it to get it repaired though as a used/refurbished rim on eBay can sometimes be cheaper.

Weld metal is stonger but also more brittle hence prone to more cracking.... then have a NON certified welder do it and not have correct filler metal or gas or procedures or machine setup and even moer prone to cracking.
TO weld properly you would also need to know the exact material wheel is made from... which is hard to find as OEMS keep that info protected.
would not take an impact to make it crack again... any harmonic like out of balance.. flat spot tire....
plenty of rocks in tread....
Just not worth a life IMHO....
A new wheel is not that much money.......

How this happen?
I don't see any mechanical damage, but see deep crack, that appears to be stress crack.
That would indicate whole wheel is having problem with internal stress.
The crack is in tire sealing point. Even if you find good welder, it is going to be hard for the wheel to hold the air.

Agreed. The tire shops tell me it's the local potholes. I am careful to avoid them but at 100+ mph I miss seeing a few. It's weird because I curb rashed both my front wheels after I purchased the vehicle, but this crack isn't opposite or that close to the outside curb rash point. Thanks.

Also you think a pothole would bend this outer part of wheel.
How ever it happend I hope it does not happen again.
Buy new wheel - or use this as excuse to get 4 new wheels of your liking.. and then seel off your other 3 individually to anyone who has severe curb rash or cracked wheel...
OR
Turn this wheel into a nice piece of Clock, artwork or furniture?
Maybe the base of a stool?
Side Table - add post and glass top.
