ChatGPT India Largest Market: Weekly Users, Voice Push and What OpenAI Plans Next, Explained

India has become ChatGPT's largest market in the world by weekly active users, OpenAI India managing director Prabhjeet Singh said on 3 November 2026, with the local user base doubling since January. The claim, reported by The Economic Times, The Times of India, Inc42 and Elets CIO, moves India ahead of the second-place ranking Sam Altman described on an earlier India visit. Here is what Singh said, what OpenAI is building for Indian users, and what the company still has not disclosed.

The 60-second version

• Claim: India is ChatGPT's largest market by weekly active users (Prabhjeet Singh to The Economic Times, 3 November 2026).
• Growth: Local user base doubled since January 2026, Singh said.
• Earlier marker: OpenAI said in February 2026 that India had more than 100 million weekly ChatGPT users (Inc42).
• Product focus: Voice, Hindi and vernacular languages, Android-first builds for entry-level phones, and UPI payment announcements in the coming weeks.
• Enterprise: Shift from pilots to production; Inc42 cites JioHotstar and Cars24; India is among Codex's largest and fastest-growing markets.
• Ads: ChatGPT advertising expanding in India via Razorpay Engage; Singh says ads do not change answers and advertisers do not get personal data.
• Undisclosed: Exact current weekly user count for India; which government agencies are in the safety talks; firm UPI launch date.

What Singh said, and how the ranking changed

Singh, in what several outlets framed as his first major media interview since taking the India MD role, told The Economic Times that India now leads ChatGPT globally on weekly active users. Elets CIO quoted him saying the base had doubled in less than a year and that the pace showed people finding "relevance and deep use cases."

That upgrades the picture Altman left after visiting India, when he called the country OpenAI's fastest-growing market and already the second largest by users. Market estimates at that time put India's ChatGPT base near 100 million. Inc42 notes OpenAI's February 2026 line that India had crossed 100 million weekly users. Singh's November interview does not republish a new absolute headcount, only the doubling and the new number-one ranking by weekly actives.

Voice, Hindi and phones that are not flagships

The Times of India reported that many Indian users hit the dictation button instead of typing, which is pushing OpenAI toward voice and Indian languages. Singh told TOI: "Most of India actually doesn't use English as a primary. So real big focus is on Hindi and vernacular."

Elets CIO added that work on Hindi and regional-language capabilities through the year is starting to show results, building on ChatGPT's Hindi voices Neer and Leher. Singh also said OpenAI is working so that phones with limited memory can still deliver the full model experience, alongside the lower-priced ChatGPT Go plan previously offered free for a year to Indian users.

Inc42 says OpenAI expects UPI and payments announcements in the coming weeks, and that the company is developing Android-first products to reach users beyond the big metros.

Enterprise, Codex and safety talks

On the business side, Singh told Inc42 that enterprises, GCCs and startups are moving past demos into production. The report names JioHotstar and Cars24. India is also among Codex's largest and fastest-growing markets, with developer use rising from tier-II cities, he said.

OpenAI's India footprint has been building since it announced a Delhi NCR office and local hiring in August 2025, then Mumbai and Bengaluru plans and an OpenAI for India programme at the India AI Impact Summit in February. Inc42 also cites a partnership with TCS HyperVault that starts at 100 MW and could scale toward 1 GW, plus model access through AWS Amazon Bedrock for local inference.

Singh told The Times of India that OpenAI is engaging government agencies, banks and financial institutions on data protection, model safety and cybersecurity so that company and government infrastructure are protected against misuse of AI agents. He did not name the agencies, the models shared, or the contractual form of those talks. He backed clear regulation as a way to build consumer and enterprise confidence while MeitY weighs rules for AI intermediaries.

Ads on ChatGPT in India

Inc42 reported that OpenAI is expanding advertising on ChatGPT in India and has partnered with Razorpay so brands can prepare catalogues, run campaigns and measure results through Razorpay Engage. Early brands named in that report include Tanishq, Fastrack, Traya, Tata Neu, Rivaah by Tanishq, Shaadi.com, Axis Max Life, Palmonas and NMIMS.

Singh said ads help support free and lower-priced access alongside paid plans, that advertisers would not receive users' personal information, and that advertisements would not influence ChatGPT's responses. Those are company statements; independent audits of ad influence were not cited in the coverage read for this piece.

What is still missing

Singh's interviews establish the ranking and the doubling claim. They do not publish the current India weekly active number, a country-by-country league table, or a dated UPI product sheet. The safety conversations with government are described as constructive but not itemised. Treat the doubling and the number-one weekly-user claim as OpenAI's disclosure through its India MD, not as a third-party audited census.

What to watch next

1. UPI and payments announcements Singh flagged for the coming weeks.
2. A public weekly active user figure for India, or a league table that shows how far ahead the market sits.
3. Hindi and vernacular voice rollouts beyond Neer and Leher, and how they perform on low-end Android devices.
4. Ad inventory growth via Razorpay Engage and whether OpenAI publishes India-specific ad policies.
5. MeitY rules for AI intermediaries, and any named government or bank deployments that follow the safety talks Singh described.

India is now OpenAI's headline ChatGPT market by weekly users. The next test is whether voice, vernacular and UPI turn that lead into durable paid and enterprise growth, not just a ranking line in an interview.

Absolute current weekly user counts for India were not republished in those interviews beyond the doubling claim and the earlier February 2026 100 million weekly-user line. Company statements on ads, safety talks and UPI plans are attributed as such.
