China's three biggest internet companies do not usually fund the same startup at once, least of all one that competes with their own products. They just did, and the reason is simple. Kling AI makes money.
Kuaishou Technology said a group of investors including Alibaba, Tencent and Baidu will inject more than 19 billion yuan, about $2.8 billion, into its AI video unit. The round values Kling AI at $15 billion before the money goes in, and near $18 billion after.
A rare AI video business with real revenue
Most AI video companies are still burning cash on demo reels. Kling AI has a profit-and-loss statement worth showing.
It generated 650 million yuan, roughly $96 million, in the March quarter. That is more than quadruple the figure a year earlier.
Its annualised revenue run rate reached about $500 million in March, up from $300 million in January, after the launch of its Kling 3.0 model. Growth like that, attached to Kuaishou's distribution, is what pulled in strategic buyers rather than pure financial ones.
Why rivals are writing cheques to a rival
The clearest signal in the round is Tencent's $200 million.
Tencent owns Hunyuan, a video model that competes head-on with Kling AI. Funding a direct competitor is not something a company does on a whim. It does it when commercial traction matters more than owning the technology outright.
Alibaba came in through its cloud arm. Baidu joined too, alongside Abu Dhabi's BlueFive Capital, CITIC Securities and other backers. Citi called the investor lineup "impressive."
The gap Sora left behind
The timing is not an accident.
OpenAI shut down the consumer version of Sora in April, after it burned through roughly $1 million a day in compute against about $2 million in total revenue. Runway, another early leader, has turned toward robotics and gaming.
That retreat left commercial AI video thinner at the top than it was six months ago. Kling AI, with paying customers and more than 60 million creators worldwide, is one of the few players left with revenue behind its valuation.
What the money buys
The raise dilutes Kuaishou's stake in Kling AI to about 68%, from 100%.
It is capped at 20.45 billion yuan, close to $3 billion, and can take in a further investor within two months. Proceeds are pointed at the expensive part of the business, compute and data-centre capacity.
Reports suggest Kuaishou wants to start a Hong Kong listing for Kling AI within 12 months. That would turn a research project it began roughly two years ago into a public company.
A muted market response
The market itself shrugged.
Kuaishou shares jumped as much as 6.9% on Friday before giving almost all of it back to end the day close to flat.
That is a fair reflection of where things stand. Investors like the lineup and the revenue, and they are waiting to see whether Kling AI's next model upgrade justifies an $18 billion price.
The question this round does not answer is whether Kling AI can keep compounding once the novelty fades, or whether it meets the same cost curve that sank Sora's consumer app. China's biggest platforms have decided they would rather own part of the answer than watch from the outside.
