Sam Altman Brings ChatGPT Ads to Cannes, Pitching Marketers Before the IPO Lights Dim

OpenAI made its debut at the Cannes Lions advertising festival, pitching ChatGPT advertising and its Codex coding assistant to brand marketers as the company seeks to build a multibillion-dollar ad business ahead of an anticipated initial public offering, the Financial Times reported on June 23. Chief Revenue Officer Denise Dresser and Vice President of Global Ads Solutions David Dugan led the presentations, which included demos of Codex, OpenAI's AI-powered coding tool, and outlined plans for contextual advertising within ChatGPT.

The Cannes Lions appearance marks OpenAI's first formal outreach to the global advertising industry, positioning the AI company alongside other major platforms courting marketing budgets. Executives detailed how brands can integrate OpenAI's AI tools into their workflows, while showing how Codex can help marketers rapidly build custom applications for creating and managing advertising campaigns. The company is seeking to diversify revenue streams ahead of going public, with advertising positioned as a core pillar of that strategy.

"We have been very clear that this is our intention to be in this space ongoing," Dugan said, noting that revenue generated from the ads offering will be reinvested into the company's compute infrastructure. OpenAI has not yet announced specific launch dates or pricing structures for advertising within ChatGPT, and the Financial Times reported that marketers attending the event were being given an early look at product roadmaps still under development.

The Cannes push comes as OpenAI's valuation has climbed past $300 billion in private markets, according to recent funding reports, with investors watching closely for signals on the company's path to public markets. Competitors including Google and Meta already operate large-scale advertising businesses built on user data, while OpenAI's pitch emphasizes brand safety and AI-driven context matching. No ticker is associated with the company, which remains privately held.
