The wider picture
SoftBank’s ongoing commitment to AI development reaffirms its long-term strategy. On February 27, 2026, SoftBank entered into a definitive agreement with OpenAI Group PBC to make follow-on investments totaling USD 30 billion. This agreement comes as SoftBank secured a US$40 billion loan to support its investment in OpenAI, which is expected to bolster the company’s growth in the rapidly evolving AI landscape.
In addition to the financial backing, OpenAI has recently crossed a significant milestone, achieving over $100 million in annual recurring revenue from its advertising initiative within just two months of its introduction. The advertising pilot, which was rolled out in January 2026, is currently limited to free-tier users and ChatGPT Go subscribers in the United States. More than 600 brands are participating in this initiative, indicating a strong interest from the market.
OpenAI has implemented category restrictions on advertisements, ensuring that ads do not appear alongside politically sensitive or health-related queries. This approach aims to maintain user trust and ensure a positive experience. The format of the ads positions them beneath the model’s responses, clearly labeled and visually separated from the output, which has been designed to enhance user experience.
In the context of competition, Anthropic has announced that it will throttle usage of its model, Claude, during peak hours to manage growing demand. This move highlights the competitive pressures within the AI sector as companies strive to optimize their services. In contrast, OpenAI has removed caps for access to its Codex platform, allowing for unlimited usage, which may attract more developers and users to its ecosystem.
SoftBank’s investment strategy is not new; the company previously announced plans to invest $100 billion in AI and related infrastructure in the US over four years in December 2024. This ambitious plan aligns with the launch of the Stargate Project, a collaboration between SoftBank and OpenAI aimed at building AI infrastructure in the US with a budget of up to US$500 billion over four years.
OpenAI’s spokesperson commented on the advertising initiative, stating, “We’re in the early testing phase of ads in ChatGPT, and the goal right now is to learn and refine the experience for consumers before expanding it more broadly.” This statement reflects OpenAI’s cautious approach as it navigates the complexities of integrating advertising into its platform.
As the landscape of AI continues to evolve, the implications of these developments are significant. Observers note that the combination of substantial investments and innovative advertising strategies could position OpenAI as a leading player in the AI market. The next steps for OpenAI and SoftBank will likely focus on scaling these initiatives and further refining their offerings to meet growing consumer demand.
With the bridge loan set to mature in March 2027, the timeline for these investments and initiatives will be closely monitored by industry analysts. The outcomes of these strategies may set a precedent for future collaborations in the AI sector, shaping the direction of technology and investment in the years to come.
