Pixalate's Q2 2026 mobile seller trust index shows arbitrage decline

Pixalate's web Seller Trust Index showed global resold authorized inventory falling to 15.3% in Q2, while earlier updates had already pointed to lower arbitrage in mobile apps and U.S. CTV.

Fact Check
Both primary Pixalate press releases (via GlobeNewswire) directly confirm every element of the claim. The CTV release states 0.7% of ranked US CTV inventory was resold through arbitrage, the lowest of any channel. The Mobile release confirms resold (arbitraged) inventory dropped to 15.2% from 16.2% in Q1 and that primary arbitrage sellers declined (globally 31.7% to 29.5%; U.S. 22% to 16%). No conflicting evidence found.

Summary

Pixalate's Q2 2026 Seller Trust Index 2.0 updates showed lower arbitrage across web, mobile apps and Connected TV. In web traffic, the quarterly public rankings covered more than 150 open programmatic sellers across more than 40 markets and found 15.3% of authorized inventory was resold globally in Q2 2026, down from 20.8% in Q1, the largest quarter-over-quarter improvement of any channel and roughly in line with mobile's 15.2%. The share of ranked web SSPs that were primarily arbitrageurs fell in France, Germany and Italy, rose in the United Kingdom and Mexico, and was flat in the United States. Earlier Pixalate updates said mobile rankings covered more than 290 open programmatic sellers across more than 125 markets, with 15.2% of authorized inventory resold globally in Q2, down from 16.2% in Q1, while U.S. CTV inventory resold via arbitrage fell to 0.7% and only 2 of 195 ranked seller listings, about 1%, were classified as primarily arbitrageurs, down from 8% in Q1.
