Agencies are moving ad budgets into ChatGPT even though the platform still offers limited measurement, Ad Age reports. The pull is simple: brands want placement inside AI-generated answers before competitors lock up early inventory.

The report highlights a familiar trade-off. Marketers gain access to a fast-growing conversational surface — and accept, for now, weak reporting on whether those placements actually drive outcomes.

What do buyers actually get?

ChatGPT ads place brands inside a channel where users ask direct questions. That context is attractive to agencies chasing high-intent audiences. The catch, per the report, is measurement: standard performance signals remain thin, so buyers are pricing in uncertainty.

Early movers appear willing to treat the spend partly as an experiment — learning the format, testing creative, and securing position while the auction is young.

Why now?

Speed matters more than certainty for some buyers. Agencies racing in suggest they fear missing a new inventory class more than they fear unattributed spend. The Ad Age reporting frames the rush as a land-grab, not a mature media buy.

Whether the bet pays off depends on measurement tools catching up with placement demand. Until then, agencies buying ChatGPT ads are working with limited visibility into performance.
