Pitch Madison, dentsu-e4m and WPP Media each size India's 2026 ad market differently. What they agree on, why the numbers diverge, and how brands should plan.
If you are planning a marketing budget in India, you will quickly find that the market has no single size. Three respected 2026 forecasts disagree by tens of thousands of crores. Understanding why is more useful than picking a number.
The three forecasts
An Exchange4media comparison published in February 2026 lined up the latest projections from the Pitch Madison Advertising Report, the dentsu-e4m Digital Advertising Report, and WPP Media's This Year Next Year (TYNY) report.
| Forecast | Total ad spend, 2026 | Digital ad spend, 2026 |
|---|---|---|
| dentsu-e4m | ₹1,30,416 crore | ₹84,770 crore |
| Pitch Madison | ₹1,74,605 crore | ₹1,11,976 crore |
| WPP Media (TYNY) | ₹2,01,891 crore | ₹1,37,563 crore |
Linear TV estimates differ just as widely, from ₹23,475 crore in the dentsu-e4m view to ₹40,995 crore in WPP Media's.
What they agree on
Despite the spread, the direction is the same. All three treat digital as the growth engine of Indian advertising. The dentsu-e4m report puts structured digital at ₹71,621 crore at the close of 2025, roughly 59% of its total, which means digital was already the largest slice of the market. Dentsu's global report also places India among the markets driving worldwide growth, citing retail media, deeper digital reach beyond the metros, vernacular content and attention-led formats.
Other findings reported from the dentsu-e4m study point to where the money is going: online video is projected to grow about 22% and take a 29% share, and programmatic is expected to reach around 43% of digital spend.
Why the numbers diverge
Exchange4media attributes the digital gap to different inclusions: how each report counts influencer marketing, retail media and performance formats. A report that counts small and medium advertisers buying directly on platforms will show a bigger digital market than one that measures only agency-planned media. Pricing assumptions for TV add to the spread.
None of these is wrong. They answer slightly different questions, and that is the lesson for planners.
What brands should do with this
Use the forecasts for direction, not for targets. They tell you digital keeps gaining, video and retail media are rising, and automation is spreading. They cannot tell you what your next rupee will return.
Plan from your own funnel. Your customer acquisition cost, conversion rate and repeat rate matter more than any industry total. Start with them, then use market data to sense-check ambition.
Shift toward measurable channels, with proof. As digital's share grows, so does the pressure to show incremental results. Build measurement in from the start, with tracking you control and holdout tests for larger bets.
Prepare for AI in media buying. With more spend flowing through programmatic and platform automation, creative quality and clean data signals become your main levers. Our article on AI advertising in 2026 covers the specifics.
Do not ignore smaller cities. Reports repeatedly cite digital growth beyond the metros and in regional languages. Local-language creative and WhatsApp-based journeys are underused by many brands.
A note on reading market reports
Check three things before quoting any figure: the definition (what is included), the year the data covers, and whether a number is an actual or a forecast. Reports revise as the year goes on, and the three above were published early in 2026, so expect updates.
