The media agency Knowlimits (non-network) remains at the top of the ranking of media agencies in the Czech Republic based on billings (invoiced advertising volumes) for 2025. This is shown by the updated COMvergence ranking. Second place in the ranking of individual agencies is held, as it was last year, by OMD (Omnicom), whilst third place is now held by EssenceMediacom (WPP Media). They are followed by PHD (Omnicom) and Wavemaker (WPP Media). This is according to the updated ranking available to MediaGuru.cz.
The first four agencies listed feature in the top five, just as they did last year, whilst Wavemaker has newly entered the top five, having also recorded the highest year-on-year growth among the top five.
Omnicom Media remains the strongest agency network on the Czech market, ahead of WPP Media and Publicis Media.
COMvergence has granted MediaGuru.cz permission to publish the top five agencies and the top three media agency networks; therefore, we are not publishing the full rankings.
From a network perspective, Omnicom Media (comprising OMD, PHD and Hearts & Science) remains the strongest. Together with the Mediabrands agencies from the Interpublic network, which Omnicom acquired at the end of 2024, the total volume rose to USD 368 million. According to the rankings, WPP Media (Essence Mediacom, Mindshare, Wavemaker, T&P) is the second largest, whilst Publicis Media (Starcom, Zenith, Spark Foundry, Razor, Performics) remains in third place, as it was a year ago.
According to COMvergence, the total billings generated by media agencies on the Czech market reached USD 1.33 billion in 2025, representing a year-on-year increase of 5.8 per cent. The market comprises 19 multinational agencies and three agencies that do not belong to the five largest global networks (Knowlimits, Mindsquared, Mediaplus). The combined market share of all media agencies in the advertising market is 74 per cent. The share of digital media in total billings was expected to account for 30 per cent in 2025.
The rankings are calculated on the basis of billings to clients whose investment in media advertising exceeds USD 100,000 (approx. CZK 2.5 million). This essentially corresponds to the 500 largest advertisers. The shares are calculated across the entire advertising sales market (not just media agencies). The net estimated figures for offline media expenditure are based on Nielsen’s monitoring data for 2025, to which COMvergence applies an 81% reduction across all media. Data on investment in digital media (display, programmatic, online video, search and social) are based on COMvergence’s own research and estimates, which rely on the use of digital shares within each category and client. These percentages are adjusted annually based on information provided by individual agencies.
Media budget shifts announced during the second half of 2025 will affect the billing figures for 2026. The exception is those that came into effect before the end of 2025.
