Sam Altman, CEO of OpenAI, reportedly holds approximately 12.2 million shares in the social media platform Reddit through his affiliated entities, currently valued at nearly $2 billion, making him the company's third-largest individual shareholder. Altman began investing in Reddit as early as its Series B funding round in 2014 and made an additional $60 million investment in 2021. Although Altman has repeatedly stated that he does not directly hold equity in OpenAI, his stake in Reddit highlights his views on the value of data owners in the age of AI. Reddit's AI data licensing business has become a significant source of revenue for the company, with an annual data agreement of approximately $60 million reached with Alphabet in 2024, and OpenAI reportedly paying Reddit about $70 million annually. AI licensing revenue is expected to contribute approximately 10% to Reddit's total revenue in 2024.
