SoftBank Vision Fund records $46 billion gain on OpenAI valuation surge
The investment arm’s annual return was driven almost entirely by the revaluation of its stake in the artificial intelligence developer, according to data released by CNBC.
SoftBank has reported a $46 billion annual gain for its Vision Fund for the fiscal year ending in 2025. The substantial return was primarily attributed to a significant increase in the valuation of the firm’s investment stake in OpenAI.
The figures, reported by CNBC on 13 May 2026, underscore the outsized impact of the artificial intelligence developer on the fund’s performance. While the total gain is confirmed at $46 billion, the source material does not provide a specific breakdown between realised and unrealised gains, nor does it detail the performance of other holdings within the portfolio.
This financial result highlights the heavy reliance of the Vision Fund on its position in OpenAI. The surge in the value of this specific holding was the main driver behind the fund’s strong annual showing, overshadowing other potential market movements or asset performances during the period.
The report comes amid a broader market environment where institutional interest in technology and AI-related assets remains high. However, the SoftBank result specifically isolates the OpenAI stake as the critical factor in the Vision Fund’s profitability for the year.
Investors and analysts will likely scrutinise the sustainability of such concentrated gains in future quarters. The data serves as a clear indicator of how valuation shifts in single high-growth assets can dictate the overall financial health of large-scale investment vehicles.
