OpenAI is aggressively expanding its advertising strategy for ChatGPT, aiming to generate $2.5 billion in ad revenue this year and a staggering $100 billion by 2030. The company announced plans to introduce ads in Brazil and Mexico in the coming weeks, with India to follow, as part of a broader push to monetize its massive user base and bolster its case for a potential initial public offering (IPO) that could value the company at up to $1 trillion.
David Dugan, OpenAI's advertising lead, revealed the expansion at the Cannes Lions festival on Monday, emphasizing that ad revenue will help fund and broaden access to information. The move comes just two weeks after OpenAI filed a confidential draft S-1 with U.S. regulators, marking a key step toward a public listing. While no timeline has been set, CEO Sam Altman has indicated the company aims to go public within the next year, though timing may shift based on market conditions.
OpenAI's IPO ambitions are fueled by its rapid user growth. The company told advertisers that ChatGPT now boasts over 920 million weekly active users, with approximately 20% of queries being commercial in nature, such as travel research or product comparisons. Ads are currently displayed for users on the free or Go tiers, positioned below ChatGPT's unpaid responses, with a clear separation to maintain user trust.
"A very clearly labeled ad, two separate models, and a clear separation from the organic results," Dugan said, outlining the company's approach to safeguarding trust. This strategy distinguishes OpenAI from rival Anthropic, which has positioned its Claude chatbot as ad-free and filed its own confidential IPO paperwork ahead of OpenAI. Michael Ashley Schulman, a partner at Cerity Partners, noted that OpenAI is "keeping options open as Anthropic edged ahead with its filing."
Despite the ambitious revenue projections, OpenAI faces significant cost pressures. The company spent $34 billion in 2025, with around $19 billion allocated to research and development, according to the Financial Times. In the first quarter of 2026, spending reached $3.7 billion on revenue of $5.7 billion, as reported by The Information. These figures underscore the high costs of maintaining and advancing AI infrastructure.
Industry analysts caution that advertising revenue from AI chatbots may not ramp up as quickly as OpenAI projects. EMARKETER forecasts ad revenue from AI chatbots to remain under $1 billion industry-wide in 2026. Additionally, an Ipsos survey found that 63% of U.S. adults say ads in AI search results would lower their trust. Weak advertiser interest or user pushback could make it harder for OpenAI to manage its computing expenses and potentially impact its IPO valuation or timing.
OpenAI's advertising push is already attracting major partners. Amazon is running ChatGPT ads that direct users to its storefront, as reported by Business Insider. E-commerce analyst Juozas Kaziukėnas described the move as "symbolic," suggesting OpenAI could "have an easier time monetizing shopping intent through ads" rather than automated shopping services.
For context, Google generated roughly $295 billion in ad revenue in 2025, while Meta brought in about $196 billion. OpenAI's projections, while ambitious, highlight the company's confidence in capturing a significant share of the digital advertising market. The Cannes Lions event is serving as both a sales push and a test run for the market, as OpenAI seeks to demonstrate that ChatGPT can monetize user intent without compromising its core product.
As OpenAI navigates the path to its IPO, the company must balance its growth ambitions with financial discipline. The success of its advertising strategy will be a critical factor in determining whether it can achieve the $1 trillion valuation that investors are eyeing, or whether high costs and market skepticism will force a reassessment.
