China Blocks SoftBank's $5.4 Billion ABB Robotics Deal: Shares Fall 6.8%

China has blocked SoftBank Group's $5.4 billion acquisition of ABB's robotics division, and SoftBank shares ended Thursday, November 5, 2026 down 6.8% in Tokyo. China's National Development and Reform Commission (NDRC) told the Japanese investor the deal will not be allowed, in a decision first reported by the Financial Times and confirmed in ABB's own response on Thursday.

What happened

SoftBank agreed in October 2025 to buy 100% of the robotics business of Swiss engineering group ABB for about $5.375 billion, with completion planned for mid-to-late 2026. The unit employs more than 7,000 people and supplies industrial robot arms to manufacturers including BMW. On Thursday, Reuters reported that China's state planner had told SoftBank the acquisition will not go ahead, and ABB said the two companies remain in close dialogue and are working on the transaction. SoftBank declined to comment, and the NDRC did not immediately respond to a request for comment.

The decision landed during an already brutal session for SoftBank in Tokyo. The shares were down about 5% before the FT report was published, hit by a wider Asian selloff in AI and chip stocks and a slide in Arm, and they ended the day down 6.8%.

Why China said no

The stated concern is data. According to the FT report cited by Reuters, the NDRC was worried that robotics data could be transferred overseas, where it could be used to train AI models, including models developed by OpenAI, in which SoftBank is a major investor. The NDRC reviews foreign investment that might have national security implications, and factory robots generate exactly the kind of real-world operating data that is valuable for training what SoftBank chief executive Masayoshi Son calls physical AI.

China's weight inside the business made its approval unavoidable. China is ABB's biggest robotics market, representing around 30% of its robot-related business, and ABB's global robotics headquarters and a major research and production base sit in Shanghai. A buyer could not simply carve China out of the deal without gutting much of its value.

Why this is blowing up

This is the second major deal blocked by China this year, after Meta was ordered to unwind its $2-billion-plus acquisition of AI startup Manus, as Beijing tightens scrutiny of foreign investment in frontier technology. The deal had already won unconditional EU approval in March, so the Chinese veto, not competition concerns, is what stopped it. The news also lands against a diplomatic spat between China and Japan following comments by Japanese Prime Minister Sanae Takaichi on Taiwan, which has already prompted China to sharply limit exports of critical minerals to Japan.

For Son, the setback is strategic, not just financial. He has billed robotics as a core component of SoftBank's AI investment strategy, pairing OpenAI models with machines that can act in the physical world. ABB's robotics arm was the largest ready-made platform for that plan, and there is no equivalent asset of the same scale sitting on the market.

Key facts

Deal value: about $5.4 billion (enterprise value of roughly $5.375 billion), agreed in October 2025 for 100% of ABB's robotics division.

Who blocked it: China's National Development and Reform Commission, the state planner that reviews foreign investment with national security implications. SoftBank was told last week, after expecting the deal to go through.

Market reaction: SoftBank shares ended Thursday down 6.8% in Tokyo, extending losses of about 5% from before the report, on a day when Asian AI and chip stocks were already selling off.

What ABB said: ABB and SoftBank are in close dialogue and working on the transaction. SoftBank is assessing what went wrong and whether it can reapply, according to the FT report.

What's next

The immediate question is whether SoftBank tries again with conditions, such as keeping Chinese robotics data inside China, or whether the veto is final. ABB had originally planned, last April, to spin off the robotics division into a separately listed company before SoftBank stepped in with its offer, so a revived spin-off is one fallback if the sale cannot be rescued. Either way, investors now have a clear signal: in the race for physical AI, robotics data has become a national-security asset, and cross-border deals in the sector face a much higher bar in China.
