Quick answer: An AI deepfake of Bombay Stock Exchange CEO Sundararaman Ramamurthy circulated on WhatsApp and Telegram starting January 2026, promising viewers extraordinary profits and Rs 8 million by 2027. BSE issued two public advisories confirming the video was fabricated. The same executive-impersonation playbook is appearing in stock-pump scams globally.
A WhatsApp message lands in a group chat. The video at the top of the message shows the CEO of a major stock exchange, speaking directly to camera, sharing exclusive stock tips and promising viewers they will accumulate Rs 8 million by 2027.
He did not record that video. Nobody at the stock exchange authorized it. The face, voice, and script were generated by AI from a real interview, then repackaged for retail investors who would never get a real CEO to speak to them directly.
This is what happened to the Bombay Stock Exchange (BSE) in January 2026, and it happened again two months later when the same video resurfaced after the platform takedown.
What Happened
A fabricated AI deepfake video falsely depicting Sundararaman Ramamurthy, BSE's Managing Director and CEO, began circulating on WhatsApp, Telegram, and social media platforms in early January 2026. The video shows Ramamurthy offering exclusive stock tips and promising "extraordinary or super-normal profits," including specific claims that viewers could become multi-millionaires and accumulate Rs 8 million by 2027.
BSE issued an urgent public advisory on January 12, 2026, confirming the video was completely fabricated and created using deepfake technology to mislead investors. The advisory clarified that neither Ramamurthy nor any BSE official operates investment groups on messaging platforms.
The takedown worked initially. The video resurfaced in March 2026, forcing BSE to issue a second advisory on March 8. The pattern of takedown plus re-emergence is now the default for high-impact deepfake content. Removing a video from one platform or one group chat does not remove it from the operator's distribution infrastructure.
The mechanism behind the scam is well-documented in 2026. Scammers take an existing public interview of the CEO, run the visual through a face-and-voice cloning pipeline, and substitute a new script that pumps specific stocks or solicits investment into a fake group. The distribution layer is WhatsApp and Telegram, where forwarding feels like a tip from a trusted contact rather than a paid ad.

of adults in India have been targeted by or know someone targeted by an AI voice or deepfake scam, roughly twice the 25 percent global average. The figure reflects how quickly the playbook scales once distribution infrastructure (WhatsApp, Telegram) reaches a market.

Why the BSE Scam Pattern Works
The executive-impersonation stock-pump variant works because it stacks three trust signals retail investors usually treat as proof.
The first is recognition. The CEO of a major exchange is a public figure whose face appears in real news coverage. A viewer who has seen Ramamurthy in legitimate interviews has no reason to doubt the face on the screen. AI generators only need a few minutes of public footage to produce a convincing clone.
The second is institutional context. A stock exchange is an authority. The fake premise (the CEO sharing tips inside a private group) plays on the assumption that institutional insiders have access to information the public does not. Real exchanges do not work that way, but the assumption is durable.
The third is platform of delivery. WhatsApp messages and Telegram channels feel personal. A forwarded video from a contact reads as a tip, not as an advertisement. The fraud bypasses the skepticism most investors apply to traditional financial ads, because the medium is not the ad medium.
The combination is what produces the volume. Retail investors get a face they recognize, an institutional frame they trust, and a delivery channel that feels like a personal recommendation, all in a 60-second clip on a phone.
The Same Playbook Is Going Global
The BSE case is the most recent and best-documented example, but the pattern is not unique to India. In the same January-to-April window, AI-generated investment-scheme ads featuring India's Finance Minister Nirmala Sitharaman circulated promising fraudulent high-return investment opportunities. In the US and UK, celebrity crypto endorsement deepfakes using fabricated videos of Elon Musk, Warren Buffett, and Mr Beast have been documented across TikTok and Facebook through 2026. In Hong Kong, the Arup $25 million deepfake CFO case was the wire-transfer variant of the same executive-impersonation trick, performed on a live Zoom call instead of a pre-recorded clip.
The technical layer is identical across these cases. The variation is who the executive is, what the false promise is, and which distribution channel the fraud uses. The detection lessons transfer in both directions.

What This Means for Anyone Receiving a Forwarded "Insider Tip" Video
Three rules that hold across the BSE case and every similar incident in 2026.
Real executives do not give stock tips in private group chats. If a CEO is genuinely speaking to retail investors, it happens through press conferences, official social media accounts, regulatory filings, and earnings calls. A forwarded clip with a specific promise of returns is, by structural definition, not an authorized communication.
Search the claim against the official channel. If a video shows a CEO endorsing a specific stock or investment scheme, search the exchange's official website, verified social media accounts, and press releases for the same claim. If the only place the claim exists is a forwarded message, the message is the fraud.
Forward the warning, not the video. When you encounter one of these clips in a group chat, sending the takedown notice or the official advisory to the group does more than sending a rebuttal of your own. The BSE advisory is public; sharing it inside the group where the deepfake was first sent is the highest-leverage response.

The Bigger Pattern
The BSE case is one variant in a fraud cluster that is consolidating fast. Executive impersonation, celebrity endorsement, and institutional-authority framing are converging on the same generation tools and the same distribution surfaces. Two years ago, producing this kind of clip required studio resources and a coordinated operation. In 2026, the cost has collapsed to a few hours of work on a consumer GPU and a free messaging platform.
The defense for retail investors is the one that has always worked: a real public figure with a real recommendation appears in more than one place. A claim that lives only in a forwarded video, only in a private group, only on a messaging platform that nobody at the institution has endorsed, has not been made by the person you think made it.
