India Becomes ChatGPT's Largest Market by Weekly Active Users

Infrastructure and enterprise push

OpenAI is also adding local computing capacity. Its partnership with TCS' HyperVault data centre business starts at 100 megawatts and could scale to 1 gigawatt, and Singh said the company would consider more capacity as infrastructure comes online. The build-out is meant to address enterprise data residency and security needs, while privacy and return on investment remain key adoption questions. OpenAI models are also available through Amazon Bedrock on AWS for local inference, which keeps request processing within India.

Singh said enterprises, global capability centres and startups are moving from pilots to production, citing JioHotstar and Cars24. India is also among the largest and fastest-growing markets for Codex, with notable developer use from tier-II cities. OpenAI is working with government agencies, banks and financial institutions on cybersecurity and on protecting critical infrastructure against AI agent misuse, and Singh backed clear AI regulation to build trust.

Ads and payments

OpenAI is expanding advertising on ChatGPT in India, which Singh said will help support free and lower-priced access alongside paid subscriptions. Through a partnership with Razorpay, its growth marketing platform Engage helps brands prepare product catalogues, run campaigns and measure performance. Early brands include Tanishq, Fastrack, Traya, Tata Neu, Rivaah by Tanishq, Shaadi.com, Axis Max Life, Palmonas and NMIMS.

Singh said the immediate priority is widening AI's impact rather than subscriptions, though paid plans are expected to grow. OpenAI is expected to announce UPI and payments-related news in the coming weeks.
