Paid AI Discovery Is Not One Channel. It's Five Different Bets.

Ask five people whether AI platforms run ads, and you will get five different answers, and all five can be right at once. ChatGPT, Perplexity, Gemini, Copilot, and Claude have made five genuinely different decisions about paid placement inside AI answers, and treating "AI advertising" as a single line item misses what is actually happening on each platform.

ChatGPT went all in

OpenAI moved the fastest and the furthest. It published its advertising principles on January 16, 2026, and launched a pilot on February 9, 2026, limited to the Free and Go tiers; Plus, Pro, Business, and Enterprise subscribers stayed ad-free. The pilot crossed $100 million in annualized revenue within about six weeks.¹

OpenAI then opened a self-serve Ads Manager on May 5, 2026: no minimum spend, CPC bidding, a Conversions API, and pixel-based measurement, reaching roughly 900 million weekly active users.¹ By August 31, 2026, the ad business had reached a $1 billion annualized revenue run rate in under 200 days, and OpenAI opened self-service buying across India, Europe, the Middle East, and North Africa.²

At Egaki, we track this expansion closely, since every new market and ad format changes where a paid placement might sit next to your brand's organic answer, and a model that recommends you for free today can carry a sponsored competitor tomorrow.

Perplexity walked away

Perplexity took the opposite path. It began experimenting with ads in November 2024, then decided to phase the program out by the end of 2025, according to Financial Times reporting. An executive was blunt about the reason: sponsored placements made users "suspicious of everything," undermining the trust the product depends on.³ Perplexity still has more than 100 million users and roughly $200 million in annual revenue, most of it from subscriptions rather than ads.³

That reversal is worth sitting with. A platform with real usage and real revenue concluded that ads were not worth what they cost in user trust, and unwound a program it had already shipped.

Gemini and Copilot split the difference

Google has kept the standalone Gemini app ad-free, a position confirmed publicly by Google Ads VP Dan Taylor in December 2025 and reaffirmed by Demis Hassabis at Davos in January 2026. But AI Mode and AI Overviews, Google's AI-powered search surfaces, already carry ads through the existing Performance Max infrastructure. The company drew a line between the assistant app and the search result page, and put ads only on one side of it.

Microsoft split its own difference differently. Copilot carries chat-based ads, a Copilot Checkout feature, and Brand Agents, all sold through Microsoft Advertising. Anthropic took the clearest position of all: Claude is ad-free by policy, and the company ran a Super Bowl ad this year criticizing OpenAI's approach to advertising directly.

Why this split matters more than any single platform's number

This is exactly the kind of divergence we built Egaki to lead on, because a brand tracking "AI advertising" as one category will miss that ChatGPT, Gemini's search surfaces, and Copilot are building out paid placement at different speeds and in different formats, while Perplexity and Claude have gone the other direction entirely. A media plan built around last quarter's landscape is already wrong, because the platforms are not moving together.

Our agency solution is the sharpest tool available for tracking exactly this kind of platform-level divergence: which surfaces carry sponsored placement, which stay organic-only, and how that changes where your brand needs to show up on its own merits versus where a budget can buy the spot instead.

What to check before committing budget

Before treating any platform's ad product as a fixed line item, it is worth confirming a few things that change faster than most media plans assume:

• Whether the specific surface you are buying into (a chat answer, a search overview, a shopping result) carries ads at all today, since that answer differs by platform and even by tier within a platform
• Whether the audience you are trying to reach is on a paid tier that strips ads out entirely, as ChatGPT's Plus and Pro tiers do
• How a sponsored placement interacts with your brand's organic standing in the same answer, since the two are not purchased the same way
• Whether the program you are planning around has existed for more than a few quarters, given Perplexity's reversal

Our context-aware tracking and the broader case for why this category needs its own measurement, covered in what GEO actually is, both start from the same premise: you cannot plan a budget around a platform's current ad policy without checking it again next quarter.

The landscape will keep moving

Perplexity's about-face is the clearest signal available that today's ad strategy can be next quarter's withdrawn feature. A platform that launched sponsored placements with named brand partners decided, within about a year, that the trust cost outweighed the revenue, and shut the program down. ChatGPT is currently making the opposite bet at considerable scale. Neither bet is settled yet.

Paid AI discovery is not a channel you buy into once. It is five ongoing experiments, running at different speeds, on different philosophies, and the only safe assumption is that the current state will not be the state in six months. We built Egaki to be the system of record for exactly that kind of change: continuous monitoring built for a landscape that will not sit still, not a one-time audit that goes stale the moment a platform changes its mind.
