News Summary:

On August 6, 2026, Pixalate's Q2 2026 CTV Seller Trust Index 2.0 ranked OpenX among the top "direct" sellers, noting that less than 1% of CTV inventory in the U.S. is resold through arbitrage, which is the lowest across all channels. The index evaluates sellers based on arbitrage and invalid traffic risk across platforms including Roku, Amazon Fire TV, Apple TV, and Samsung TV. This follows OpenX hosting multiple panels at Cannes. On July 31, 2026, OpenX hosted a technology-focused discussion on privacy infrastructure in digital advertising, examining data clean rooms, containers, and interoperable adtech solutions, featuring Joel Meyer, CTO at OpenX.
