One publisher, three sellers, three prices.

Price gaps are the most common form of money at risk we find, and the least visible. Across the 10 deals we audited, they made up 78% of all money at risk.

All three seats were authorised. Nothing was fraudulent. But in that deal, 30.8% of spend was exposed to the gap, and one publisher accounted for 86% of it.

It isn't a one-off

In another deal, a single publisher reached the buyer through three seats at up to 3.2x the cheapest authorised price. Across that deal, $4.6k was exposed to price gaps.

Why reports miss it

Price differences between sellers of the same inventory don't show up in standard delivery reporting. They only become visible when the whole deal is audited independently.
