Which sentence is correct, or I should use?
The verb "to expand" has a transitive definition meaning "to make larger". "To expand" also has an intransitive definition meaning "to become larger".
Your examples are one of each. The first sentence is the transitive verb's passive form, which implies conscious action -- someone will make the markets grow. The second sentence is transitive and simply means the markets will grow, but does not imply this is a result of any conscious effort.
Other examples:
This constant noise must be stopped! (transitive passive)
The noise will stop (intransitive) after we are finished.
If you don't stop it (transitive active), I will!
Ok, since you want it to stop (intransitive) we will stop it (transitive).
