I think it's good for crypto space since polymarket uses crypto and it's re-entering the US space, so it's natural that NYSE it any other company takes a bite of the cake while it's still hot. NYSE jumped into polymarket to make profits too on a personal orientation since they'll be monetizing it's data. It's a win win situation both for the polymarket and NYSE and other data driven industries might follow suit with time.
And the long and short of this is that it's a positive news for the entire crypto currency ecosystem, like I said in my previous post, when traditional companies are starting to bring their money into cryptocurrency oriented businesses and companies, its a true indication that cryptocurrency is gradually achieving mainstream adoption, and I look forward to the day when it's becomes absolutely hard to differentiate between a crypto business and a traditional business due to its mix.
And yeah, NYSE possibly have done their thorough research and investigation and saw a huge profit opportunity/potentials in investing in polymarket, because I personally know or atleast, have an idea of what it takes for a company with such high level of reputation to find a smaller up and coming company worthy of their investment.
