China’s regulatory crackdown has ensnared sectors from technology to education to property, wiping hundreds of billions off the market capitalisations of some of its largest companies and putting investors on alert over who may be next.

Here are some of the largest names that have been affected so far:

Alibaba Group

The woes of China’s biggest e-commerce company began late last year when China abruptly suspended the record US$37 billion stock market debut of its financial affiliate Ant Group and later fined Alibaba $2.75 billion for abusing its market dominance.

The company’s US-listed shares have shed more than $400 billion in value since late October, when its founder Jack Ma made a speech that blasted China’s regulatory system, which is widely regarded as the trigger for the government backlash that followed.

Alibaba’s sprawling empire of businesses has continued to face heat from regulators, over issues ranging from their use of algorithms, to consumer privacy and worker protections.

Tencent Holdings

China’s largest gaming and social media company has lost more than $347.13 billion in market value since its shares reached a peak in mid-February.

The company has been fined for failing to report past deals to anti-trust regulators, its $5.3 billion plan to merge China’s top two videogame streaming sites was blocked and it has been barred from entering music copyright agreements.

Tencent has also been affected by China’s latest efforts to combat gaming addiction among minors. In August under-18-year-olds were banned from playing video games for more than three hours a week.

Didi Global

China’s largest ride-hailing company became the target of a cybersecurity investigation by Chinese authorities days after its New York initial public offering in June, who ordered its app to be removed from Chinese app stores and barred it from registering new users.

Its shares have lost about $37 billion, or more than 40 per cent, of their value since it raised $4.4 billion from its June 30 IPO.

The company has also been criticised by state media over how it pays its drivers. Reuters has reported that Didi is in talks with state-owned Westone Information Industry to handle its data management and monitoring activities.

Meituan

The food delivery company became the target of an antitrust probe in April and experienced a sell off in its shares a month later after its founder and CEO Wang Xing posted an ancient poem on social media that was perceived by some as criticising the government and President Xi Jinping.

Meituan, whose share have lost more than $154.28 billion in value since reaching their peak in February, has also been criticised on other matters, including treatment of its delivery riders and violation of consumer rights.
