China Begins Anti-monopoly Probe of Alibaba Agence France-Presse BEIJING - China has launched an anti-monopoly investigation into Alibaba, regulators said Thursday, heaping further pressure on the e-commerce giant and sending its share price tumbling. Regulators will also hold "supervisory and guidance" talks with Alibaba's gigantic financial services subsidiary Ant Group, state media reported, just weeks after Beijing halted its record-breaking IPO at the last minute. The moves demonstrate mounting state pressure on one of the country's most influential companies, whose success revolutionized the e-commerce landscape and made its founder Jack Ma China's richest man. Investigators are looking into Alibaba for "suspected monopolistic practices," the State Administration for Market Regulation said in a statement. Alibaba shares tumbled 5.48% on the news shortly after the Hong Kong Stock Exchange opened Thursday morning. Its financial services subsidiary Ant Group said in a statement that it would "diligently study and strictly comply with regulatory departments' requests." Ant Group made its name via its main product Alipay, the online payments platform and super-app that is now deeply embedded in China's economy. But the company has also expanded into offering loans, credit, investments and insurance to hundreds of millions of consumers and small businesses, spurring fear and jealousy in a wider banking system geared more for supporting state policy and large corporations. As global demand for the dual Hong Kong-Shanghai listing pushed the IPO toward record valuations -- potentially handing Ma and Ant Group even more funding, legitimacy and clout -- Chinese regulators acted. .
