DoubleVerify (NYSE: DV) became the first measurement vendor to earn Media Rating Council (MRC) accreditation for TikTok video viewability reporting, the company said Thursday. The stamp covers direct measurement of impressions, viewable impressions, related viewability metrics, and sophisticated invalid traffic filtration on the TikTok mobile app, reported through DV Pinnacle.
It is the third platform-specific MRC viewability accreditation DoubleVerify has earned first, after YouTube in April 2022 and CTV in April 2024. Integral Ad Science (NASDAQ: IAS), DoubleVerify’s primary competitor in third-party verification, announced on April 20 that it had expanded Total Media Quality coverage to four more TikTok placements, including Search Ad Campaigns, GMV Max U.S., and TikTok Lite U.S. The IAS release did not claim MRC accreditation. The same pattern played out on YouTube, where IAS trailed DoubleVerify by roughly 24 months on the same accreditation, and on CTV, where IAS has not announced one. DoubleVerify CEO Mark Zagorski has built the standardization-as-moat playbook around being there first; the TikTok stamp is its fourth iteration after DV Authentic Attention shipped on TikTok in December. MRC’s own news index has not yet posted a standalone confirmation; the Tier 1 anchor for the accreditation is George Ivie’s quote inside the DoubleVerify release, with the next public MRC quarterly update due after the April 17 roll-up.
The accreditation is the first major third-party measurement investment to clear after TikTok’s U.S. joint venture closed on January 22, with Oracle (NYSE: ORCL), Silver Lake, and MGX holding 50 percent, existing investors 30.1 percent, and ByteDance 19.9 percent. The stamp lands as TikTok’s commercial leadership turns over: Blake Chandlee stepped down in March 2025 and Khartoon Weiss left April 10 for Google (NASDAQ: GOOGL), Bloomberg reported, with Adam Presser running the U.S. JV. For buyers, MRC accreditation is the procurement-grade validation that lets upfront and audit teams treat platform-supplied numbers as currency-adjacent. TikTok has been pitching upfront-grade inventory through Pulse and Pulse Premiere for several upfront cycles on measurement no third party had stamped to that standard. The May–June upfront commitments cycle will be the first in which TikTok can sell against an MRC-accredited third-party viewability spec.
DoubleVerify reports Q1 2026 results on May 6 after market close, with a 4:30 p.m. ET call, the same day as Magnite (NASDAQ: MGNI).
