For an overview of open market pricing, you might look at https://ipv4marketgroup.com/ipv4-pricing/.

You may also find this talk interesting in context:
Mythic Beasts, which is a data center operator in London, gave a talk to the IPv6 Operations Working Group in the IETF 
two years ago, and used these slides: 
https://www.ietf.org/proceedings/101/slides/slides-101-v6ops-ipv6-only-hosting-00. If you look through them, you'll 
find a discussion of the address shortage and what impact it has on pricing from them.

In short, Mythic Beasts find that IPv6 service is virtually free, and don't charge for it. They find that when a 
customer pushes them to also give IPv4 addressing, they have to charge, as it costs them, and they find that making the 
customer engineer explain to his/her bean counters why the need it often has the effect of convincing the company to 
use IPv6 externally.

In short, yes, there is a shortage of IPv4 addresses, and the net result is both an increase in price and an increase 
in network complexity.
