ChatGPT-Maker OpenAI Seeks $500B Valuation in Share Sale

OpenAI is reportedly in early talks for a secondary stock sale aiming for a $500 billion valuation, a substantial increase from its recent $300 billion valuation. This potential deal would allow current and former employees to sell shares and further cement its position as a highly valued private company. The move follows strong operational growth, with ChatGPT reaching 700 million weekly users and annual revenue hitting $12 billion, though the company also projects increased expenses of $8 billion in 2025 for infrastructure development.

Analysis

OpenAI is reportedly exploring a secondary stock sale that would value the company at approximately $500 billion, a significant increase of about two-thirds from its recent $300 billion valuation. This sharp appreciation is underpinned by powerful fundamental momentum, including a surge in ChatGPT's weekly active users to 700 million from 500 million in March and a reported annual revenue run-rate of $12 billion, which has more than doubled from $5.5 billion in December 2024. The strong demand from both consumer and enterprise segments is driving this top-line expansion. However, this hyper-growth necessitates substantial capital investment, with projected expenses for 2025 rising to $8 billion—$1 billion more than prior estimates—largely for critical infrastructure like computing chips and data centers. The potential transaction, which would provide liquidity for employees and reportedly involves investors like Thrive Capital, underscores the massive private market appetite for premier AI assets. For prior investors such as SoftBank (SFTBY), this valuation uplift serves as a strong validation of its venture strategy in the AI sector.

Key Decisions for Investors

• As direct investment in OpenAI is unavailable to the public, investors should consider that its projected $8 billion in 2025 infrastructure spending signals sustained, high-margin demand for publicly-traded suppliers in the AI value chain, particularly in semiconductors and data center infrastructure.
• Investors in SoftBank (SFTBY) should view the material valuation uplift of its portfolio company as a positive catalyst, reinforcing the value within its venture holdings and validating its AI investment thesis.
• The proposed $500 billion valuation sets an aggressive new benchmark for the private AI market; while growth metrics are strong, potential investors must weigh this against the escalating capital expenditures and the high execution risk embedded in such a valuation.
