SoftBank's Vision Fund 2 has proposed to purchase shares valued at $1.5 billion from OpenAI employees at a price of $210 per share, aligning with OpenAI's $157 billion valuation. Employees are required to make a decision by December 24th.

This deal is significant as SoftBank intends to deepen its investment in OpenAI, while simultaneously offering employees a rare liquidity opportunity amid the currently sluggish IPO market.

A closer analysis reveals that this transaction underscores SoftBank CEO Masayoshi Son's aggressive expansion strategy within the artificial intelligence sector. It is reported that since the initial $500 million investment, Son has "consistently sought to secure a larger stake."

Regarding specific figures, OpenAI anticipates generating $3.7 billion in revenue this year, although it simultaneously expects a $5 billion loss. The company has raised approximately $13 billion from Microsoft, with the latest funding round bringing in an additional $6.6 billion. Notably, OpenAI now permits both current and former employees to uniformly participate in annual stock sales, addressing prior concerns related to liquidity.

Broadly speaking, SoftBank's move is part of its recent investment surge in AI startups, including companies like Glean and Perplexity. Artificial intelligence has become a central focus in the technology sector, with commercial spending on generative AI skyrocketing by 500% this year and the market revenue projected to exceed $1 trillion within the next decade.

Moving forward, OpenAI expects to facilitate additional secondary market transactions and may tap into private market financing once again, given investor demand and the capital-intensive nature of AI development.
