ADI Predictstreet's $108 Million in Trading Volume Is Being Questioned

ADI Predictstreet, the official prediction market partner for FIFA's 2026 World Cup, is facing questions about its trading volume. According to an analysis of blockchain records, about $108 million of the $167 million in trading through the end of September came from wallets that appear to be linked to the platform.

Since the end of August, a network of 795 wallets has accounted for 99 percent of trading volume. The accounts were reportedly funded from a single crypto wallet, and the same wallet also collected the platform's trading fees. The wallets traded almost exclusively with one another rather than with independent users. The network was identified by three Harvard University students, and the crypto analytics firm Solidus Labs confirmed the findings. During the World Cup, just two wallets traded more than $81 million across hundreds of markets, after which volume dropped markedly.

This picture raised the possibility of circular trading, in which linked accounts trade with each other to create the appearance of volume and liquidity. The available data, however, does not prove deliberate manipulation, nor does it show who controls the wallets.

The platform holds a Gibraltar license. Gambling Commissioner Andrew Lyman said a preliminary review found no breach of local rules against self-trading and no evidence of consumer harm. ADI Predictstreet did not respond to requests for comment, and FIFA declined to comment. The platform was reported to have paid more than $150 million for exclusive advertising rights.
