WSJ investigation questions $108m of ADI Predictstreet trading volume

A Wall Street Journal investigation has questioned part of the trading volume reported by ADI Predictstreet, the prediction-market platform commercially linked to FIFA. The platform had traded about $167m by the end of September, but the analysis found that roughly $108m may have come from repeated trades between related accounts.

The review identified 795 digital accounts that received money from a single account tied to the platform's commission system. The report describes the suspected pattern as circular trading, in which the same money moves repeatedly between related accounts rather than new money entering the market from independent users.

FIFA selected ADI Predictstreet as its official prediction-markets partner for the 2026 World Cup, giving the platform visibility and allowing it to create markets on matches, national teams and players using official competition data, according to the report. When the agreement was announced, FIFA said there would be controls to detect suspicious transactions and to ensure transparency.

The report says the investigation raises questions about how the platform's activity volume is calculated, and whether the $167m figure reflects trading by thousands of separate users or partly the same money circulating between related accounts. The source gives no response from ADI Predictstreet or FIFA to the investigation, and no appeal or regulatory status.
