NFT buyers of Ice Cube's BIG3 basketball league have filed a class-action lawsuit in California, accusing the league of fraudulent marketing during its 2022 Ethereum NFT sale. The NFTs, sold in Fire and Gold tiers at $25,000 and $5,000 respectively, promised perpetual rights including team ownership and a share of future sale proceeds. However, these promises were allegedly not fulfilled. In 2024, BIG3 sold four teams for $40 million, with NFT holders claiming they were entitled to a share as early investors. BIG3 argues disputes should be resolved through arbitration, not public lawsuits. The league recently announced plans to go public via a SPAC merger valued at $290 million.
