Pixalate Q2 2026 Report: Web Ad Arbitrage Falls to 15.3% (AMZN)
What happened
Ad-transparency firm Pixalate said its Q2 2026 Web Seller Trust Index 2.0 measured arbitrage in the global authorized web ad supply at 15.3%, versus 20.8% in the prior quarter. The report tracks programmatic supply-chain integrity across major exchanges and seller platforms relevant to Amazon's advertising ecosystem. The 5.5 percentage-point quarter-over-quarter decline is the largest single-quarter improvement recorded in the index series.
The QL Read
AMZN's internal composite signal reads 67/100, against a broader tape in which 43.6% of issues are advancing. Improving programmatic supply-chain hygiene is a factor that could bear on Amazon Ads margin quality, a metric to monitor into the next earnings call.
