StockX, which calls itself ?the world?s first stock market for things,? has told Business Insider that PlayStation 5 consoles are outselling Xbox One X/S nearly 2-to-1 in the resale market.
A quick search on the website shows about 30 results for the PS5, with prices going up to $900. However, buyers are allowed to bid so $900 is the absolute minimum that the seller expects to receive. Xbox One X seems to be going for slightly less, with the lowest asking price of $729.
