To compile this research, Pixalate’s data science team analyzed over 4 billion global open programmatic advertising transactions across over 6,800 unique CTV apps in Q4 2025. Invalid Traffic rates are calculated at the Bundle ID level using the estimated volume of invalid traffic (inclusive of spoofing) as measured by Pixalate.
Free Ad-Supported TV (FAST) apps allow viewers to access “linear” video content in a channel-based format without subscription fees, unlike streaming platforms that rely on viewer subscriptions. In the context of this report, “linear” refers to content presented in a channel-based format, where the same programming is simultaneously streamed to all viewers tuned into a specific channel.
Pixalate classifies any CTV app meeting the above FAST criteria as a ‘FAST app,’ even if the app provides video-on-demand services or offers paid subscription tiers in addition to the free, linear content.
Pixalate is a global platform for privacy compliance, ad fraud prevention, and data intelligence in the digital ad supply chain.

Per the MRC, “'Fraud' is not intended to represent fraud as defined in various laws, statutes and ordinances or as conventionally used in U.S. Court or other legal proceedings, but rather a custom definition strictly for advertising measurement purposes. Also per the MRC, “‘Invalid Traffic’ is defined generally as traffic that does not meet certain ad serving quality or completeness criteria, or otherwise does not represent legitimate ad traffic that should be included in measurement counts. Among the reasons why ad traffic may be deemed invalid is it is a result of non-human traffic (spiders, bots, etc.), or activity designed to produce fraudulent traffic.”
