Linked wallets reportedly accounted for 99% of FIFA partner ADI Predictstreet’s activity since late August

The Wall Street Journal reports that an analysis of public blockchain data by three Harvard students found a network of 795 wallets accounted for 99% of ADI Predictstreet’s activity since late August. The wallets were funded by an account collecting the platform’s fees and traded almost exclusively with one another. Gibraltar’s gambling commissioner said a preliminary review found the platform complied with local rules prohibiting self-trading. ADI Predictstreet did not respond to the Journal’s request for comment.
