ADI Predictstreet is facing scrutiny after blockchain analysis linked approximately $108 million of its $167 million in trading through late September to connected cryptocurrency wallets. The analysis showed a network of 795 wallets accounted for almost 100% of the platform's trading volume registered as of the end of August 2022; it does not, however, prove manipulation.
What the blockchain analysis found
Analysts report a single cryptocurrency address funded the 795 wallets, which were also recipients of a small number of transaction fees. The wallets traded with each other, and during the World Cup two wallets were involved in trading for more than $80 million across hundreds of markets before those transactions began to decline. The network was discovered by three students from Harvard University and the findings were confirmed by companies involved in blockchain analysis.
Commercial and regulatory context
FIFA named ADI Predictstreet its official prediction market partner for the 2026 World Cup, and the platform reportedly paid more than $150 million for exclusive advertising rights associated with the tournament. The blockchain findings have raised questions about ADI Predictstreet's trading activity and the effectiveness of its monitoring safeguards, but the analysis stopped short of establishing wrongdoing.
Remaining questions
Investigations will need to determine whether connected-wallet trading reflected an internal liquidity mechanism, coordinated market activity, or activity that breached platform rules. The blockchain analysis provides transaction links and volumes but not definitive proof of intent or manipulation.
