- Record China mobility transaction volumes and 26.9% international transaction growth lifted Q2 2026 revenue.
- Core China mobility produced RMB4.2 billion adjusted EBITA in Q2 2026, funding expansion.
What critics are saying
- The $740 million U.S. class settlement approved June 16, 2026 drains cash and resets scrutiny.

↑ 0%Didi Global returned to profitability in Q2 with a net income of $128 million. The Chinese ride-hailing giant holds over 70% of China's domestic market despite facing competition from Alibaba's Amap and at least 339 other platforms offering discounted fares 10% to 40% below regular prices. The company delisted from the New York Stock Exchange in 2022 following a cybersecurity probe by Chinese regulators, which resulted in an 8 billion yuan ($1.19 billion) fine in July 2022. Didi is pursuing international expansion and now operates in 14 countries, including Hong Kong, as it diversifies beyond mainland China.
DiDi Global has raised investor interest despite mixed performance, with shares down 34% year-to-date but gaining over the past three months. The company reported revenue of CN¥232.2 billion and a net loss of CN¥2.6 billion, whilst achieving 8.9% annual revenue growth. The stock trades at a price-to-sales ratio of 0.5x, significantly below the transportation sector average of 1.9x and an estimated fair ratio of 1.2x. Simply Wall St's DCF model suggests a fair value of $20.83 compared to the current price of $3.66, indicating substantial undervaluation. However, ongoing losses and a 24.5% decline in one-year shareholder returns highlight persistent profitability challenges. The steep discount may reflect market concerns about the company's path to profitability despite revenue growth.
DiDi Global shares have declined 27% over the past three months, with the stock trading at $3.42. Despite revenue of CN¥226.7 billion and net income of CN¥992.6 million, the company's price-to-earnings ratio stands at 105.7x, significantly above the US Transportation industry average of 39.7x and peer average of 26.5x. Analysts forecast earnings growth of 49.7% annually over the next three years, with return on equity projected at 12.3%. However, the current P/E multiple exceeds the estimated fair value of 46.1x, suggesting the market has priced in substantial optimism. The company operates mobility platforms across China and international markets through its China Mobility, International and Other Initiatives segments. The valuation premium could narrow if market sentiment shifts.
Xiaoyubot, China's leading industrial embodied AI company, has raised a new funding round worth several hundred million yuan.

The company specialises in industrial embodied AI solutions. No further details about valuation or specific use of funds were disclosed.
Beijing XiaoYu Intelligent Technology has completed hundreds of millions of yuan in Series B+ funding, with investment from BAIC Capital, Fosun RZ Capital and C&D Emerging Industry Equity Investment. Existing shareholders Huaye Tiancheng and Guizhou Science and Technology Innovation Angel Fund co-invested, whilst Didi Chuxing and Xiaomi co-founder Li Wanqiang made additional investments. Founded in 2023 by former Xiaomi MIUI R&D head Qiao Zhongliang, XiaoYu Intelligence develops general-purpose embodied intelligence technology using a "One Brain, Multiple Forms" architecture that enables a single AI system to control different robot types. The company has focused initially on industrial welding, deploying its intelligent agent in production lines since Q4 2025. It recently signed a strategic cooperation with China Construction Science and Industry to deploy 1,000 embodied intelligent welding robots in construction steel structures within the next year.
