Coinbase launched its NFT Marketplace 5/4 and did $75,000 in volume (~25 ETH). GameStop's Marketplace is live less than a day and individual creator's projects have more volume than Coinbase did for the whole day!

on-chain data showing a maximum of 150 total transactions on the day and a $75,000 volume.
ETH was ~2943.42 that day, so Coinbase did a little over 25 ETH in volume.
You can see a GameStopNFT project's total volume when you open them up. One creator I was looking at has project(s) that have done more volume than that already.
Check it out yourself but it is night and day different in terms of launches!
