Don't think so, his current market value is way lower, probably not over 100 mil.
He will be a free agent in 6 months.
Since his contract is almost over, I agree that his market value even below €100m. Real Madrid must prefer to wait for 6 months, until the end of his contract. If Real Madrid tries to sign him in January, probably there is another drama with Mbappe. It is better to be patience, 6 months isn't a very long time to wait for Mbappe.
Well, being more patient until you actually get Mbappe as free agent is the best thing to do because Real Madrid can get him without needing lot of drama or lot of haggling with PSG who are still trying to keep him.
Mbappe might actually leave PSG and until now there has been no clearer update regarding his contract.

Mbappe gets difficulty to succeed like in 2018/19 season, he isn't in a lucky condition lately. He lost some good teammates in PSG, Messi and some great players are leaving PSG. There is also no big competition yet, Mbappe only focus on domestic competition. Sure, Mbappe probably can win the Ligue 1 trophy only. We can't see something interesting in Mbappe's career recently. So, it is very reasonable to see the market price of Mbappe is decreasing a lot during this year.
That what happened, and the departure of Messi and Neymar caused the PSG squad to experience significant decline. Even though Neymar didn't really contribute much because he was often injured, Messi was still one of the important players in PSG attack line last season.
Now Mbappe has to fight alone, he has to be able to play very well to bring PSG success and this is one of the reasons for the setback that occurred.
Plus, in 2022 France will also fail in the World Cup so Mbappe can't achieve anything except the Ligue 1 title.
