Key Takeaways
- • SoftBank is in advanced talks to acquire a majority stake in 1X Technologies, an OpenAI-backed humanoid robot developer, at an approximately $6 billion valuation.
- • The transaction would represent a significant expansion of SoftBank's artificial intelligence and robotics exposure, complementing its existing 11% stake in OpenAI (valued at over $60 billion in total OpenAI commitments).
- • 1X previously attempted to raise $1 billion in funding, suggesting the $6 billion valuation reflects substantial growth in the robotics sector's perceived value within AI-driven markets.
- • SoftBank, led by billionaire Masayoshi Son, continues aggressive capital deployment in the AI ecosystem, positioning itself as a dominant institutional player across multiple adjacent technology verticals including chipmaking (Arm) and generative AI.
Summary
SoftBank Group Corporation is negotiating to purchase a majority stake in 1X Technologies, an OpenAI-backed humanoid robotics developer, according to multiple financial sources. The transaction would value the startup at approximately $6 billion, marking a significant strategic investment in the autonomous robotics and artificial intelligence sectors.
1X Technologies represents a key asset in the emerging humanoid robotics market, backed by OpenAI—one of SoftBank's largest portfolio companies. SoftBank's investment stake in OpenAI has grown substantially, reaching 11% ownership following a $22.5 billion investment in December 2025, with total OpenAI commitments exceeding $64 billion. This proposed acquisition of 1X would deepen SoftBank's exposure to AI-adjacent robotics while leveraging its existing relationship with OpenAI.
The $6 billion valuation for 1X represents a substantial increase from the startup's previous fundraising efforts. The company had previously attempted to secure $1 billion in capital, indicating significant investor confidence and market momentum in the humanoid robotics space. The timing of this potential transaction reflects broader institutional appetite for robotics and automation technologies in the context of accelerating AI adoption across industries.
SoftBank's investment strategy, under founder Masayoshi Son's leadership, continues to concentrate capital in transformative technology sectors. Beyond OpenAI and the proposed 1X investment, SoftBank maintains significant exposure through Arm Holdings, which has experienced substantial valuation growth following its artificial intelligence market repositioning. This diversified approach across generative AI, robotics, and semiconductor design positions SoftBank as a concentrated bet on AI infrastructure and applications. The proposed majority stake in 1X would further consolidate this positioning within the automated systems ecosystem.
