In my opinion these are not completely valid comparisons, because how much of free advertisment Polymarket received during the presidential campaign for the presidency of the United States and how even political commentators give importance on the odds which were being shown on Polymarket.
Both offer similar style of markets which is why it is a valid comparison. Main difference is that Polymarket offers many popular short term markets when compared to Futuur where there are few in comparison.
With the order book, many people will be able to leave their bet programmed and at the moment the desired price/share is obtained, the operation is concluded.
This is a good development, but I wish the liquidities on sports markets were a lot higher since 80-90 bucks is way too low.
