π The latest Pixalate report is out, and it's a crucial read for anyone in programmatic advertising.
The Q2 2026 Mobile Seller Trust Index 2.0 reveals that 15.2% of global authorized mobile app inventory is now resold through arbitrage, down from 16.2% in Q1. This indicates a continued push toward supply chain transparency, but the data shows it's a mixed bag across different regions.
Key Findings: The Global Picture
- Global Arbitrage Rate: Decreased from 16.2% (Q1) to 15.2% (Q2).
- US SSPs: The share of primarily arbitrage-focused sellers dropped significantly from 22% to 16%.
- Regional Divergence: While the US, Canada, Australia, Germany, and the UK saw improvements, Brazil (+13 pp) and Singapore (+8 pp) saw a worrying increase in arbitrage-focused SSPs.
This data suggests that while the broader ecosystem is cleaning up, certain emerging markets are still struggling with supply path optimization.

The Bottom Line
The decline in arbitrage is a positive signal for advertisers seeking brand safety and transparency. However, the report highlights that significant challenges remain, especially in regions like Brazil and Singapore. For publishers, this data underscores the importance of clearly declaring direct relationships in app-ads.txt to build trust with buyers. For advertisers, it's a reminder that even top-tier sellers like Google AdExchange carry inherent invalid traffic risks, making third-party verification an essential part of any mobile strategy. π
