OpenAI Pursues Massive $100B Funding Round at $830B Valuation Amid Rising Compute Costs

OpenAI is reportedly seeking to raise up to $100 billion in funding that could value the company at $830 billion by the end of Q1 2026, potentially involving sovereign wealth funds. The fundraising effort comes as OpenAI faces escalating compute costs for inference, intensifying competition from rivals like Anthropic and Google, and broader market skepticism about sustained AI investment levels. The company currently generates approximately $20 billion in annual run-rate revenue and holds over $64 billion in existing capital.

OpenAI's o3 Reasoning Model May Cost Ten Times More Than Initially Estimated

The Arc Prize Foundation has revised its estimate of computing costs for OpenAI's o3 reasoning model, suggesting it may cost around $30,000 per task rather than the initially estimated $3,000. This significant cost reflects the massive computational resources required by o3, with its highest-performing configuration using 172 times more computing than its lowest configuration and requiring 1,024 attempts per task to achieve optimal results.

OpenAI Expands GPT-4.5 Access Despite High Operational Costs

OpenAI has begun rolling out its largest AI model, GPT-4.5, to ChatGPT Plus subscribers, with the rollout expected to take 1-3 days. Despite being OpenAI's largest model with deeper world knowledge and higher emotional intelligence, GPT-4.5 is extremely expensive to run, costing 30x more for input and 15x more for output compared to GPT-4o, raising questions about its long-term viability in the API.
