Rumours of a partnership between the two started when Matt Finestone was hired as the head of Blockchain at GameStop from Loopring.
Since then Loopring have confirmed the announcement in Q4 of a NFT marketplace by a premium partner: https://medium.com/loopring-protocol/loopring-quarterly-update-2021-q3-bd083d94ca17
we are working with an established partner who is building atop our newly released L2 NFT functionality. We are very excited to share more on this as soon as we can. This new marketplace is set to launch sometime prior to the end of 2021(Q4).
