ADI Predictstreet wallet self-funded near-total FIFA prediction volume since late August

ADI Predictstreet, a platform backed by Abu Dhabi’s royal family, has been identified as the source of nearly all trading volume in its FIFA-partnered prediction market. According to a Wall Street Journal analysis, 795 accounts funded by the company’s own fee-collecting wallet generated 99% of the market’s activity since late August. This concentration involves accounts linked directly to the platform's operational wallet.

Root cause

The volume originated from ADI Predictstreet’s fee-collecting wallet. The Wall Street Journal analysis found that 795 accounts were funded by this specific wallet. This internal funding source drove 99% of the activity in the FIFA-partnered prediction market. The report does not specify the intent behind the funding, only that the wallet provided the capital for these accounts.

Mitigation

• Review internal wallet access controls to prevent self-funding of user accounts.
• Implement real-time monitoring for circular transaction patterns between corporate and user wallets.
• Audit trading volume sources to distinguish between organic user activity and platform-generated volume.
• Establish independent verification protocols for market liquidity claims made to partners.

What it means for organisations

Organisations should assess how they verify partner integrity when relying on third-party platforms for user engagement. Teams usually review financial flows to ensure market activity is genuine and driven by independent participants. Check whether internal wallets can fund user accounts without detection. Compliance and risk teams need to be informed of potential reputational exposure if partner platforms manipulate volume metrics. Suppliers of such platforms should face stricter auditing requirements to prevent artificial inflation of activity data.

What to do and how to stay safe: ADI Predictstreet

• Audit your platform’s wallet architecture to ensure corporate funds cannot flow into user trading accounts without explicit, auditable separation.
• Implement transaction monitoring tools that flag circular flows between internal treasury accounts and external user-facing identifiers.
• Require third-party partners to provide transparent, third-party-verified metrics for user engagement and trading volume.
• Review contractual obligations with partners to include clauses preventing artificial inflation of market activity or user metrics.
