OpenAI presents advertising as the price of keeping AI widely available, while its critics see a test of whether a conversational assistant can sell without compromising the trust that made it useful. India, with its enormous base of lower-cost ChatGPT users, is now central to that wager.

The company had already been building its Indian consumer foothold with the ₹399-per-month ChatGPT Go tier, promotions and sports-marketing campaigns. It says more than 100 million people in India use ChatGPT weekly, with many on Free or Go plans—making the country a natural market for an ad-supported model.¹

OpenAI began rolling ads out internationally before extending the program to India’s Free and Go users. Managed advertising arrived first; self-service buying, which lets marketers bid directly for impressions, is set to follow. The initial Indian campaign involved 50 brands and agency partners WPP and Omnicom, with an ad manager intended to open the market to businesses with daily budgets from ₹725.¹

For OpenAI, the argument is straightforward: advertising is one revenue stream alongside subscriptions, enterprise products and APIs. The company says the platform has reached a $1 billion annualized revenue run rate in under 200 days and now serves more than 1 billion weekly active users through a mix that includes a free, ad-supported tier.² Its pitch to advertisers is that ChatGPT catches people while they are comparing options, planning purchases or making decisions: “Where decisions take shape.”²

That commercial logic comes with an unusually sensitive promise. OpenAI says ads will be labeled, visually separate and placed below responses; “Answer independence is non-negotiable.”³ It also says advertisers will not see private conversations, personalization can be controlled by users, and ads are withheld from people identified—or predicted—to be under 18.²

Skeptics see the pressure behind the assurances. OpenAI is trying to strengthen revenue ahead of a prospective public listing while competing with enterprise-focused Anthropic and cash-rich Google. Anthropic has drawn the clearest line, pledging Claude will remain ad-free and rejecting sponsored links or third-party influence over answers.³ India will show whether OpenAI can turn attention into revenue without turning conversation into inventory.
