Kuaishou Technologyās AI spinoff unveils Kling 4.0 video model ahead of Hong Kong listing
The generative AI video unit has hit $500 million in annualized revenue and is gunning for a standalone IPO as competition with ByteDance heats up
Kuaishou Technology just gave its AI video spinoff a serious upgrade. Kling, the generative video unit the Chinese tech company has been grooming for a standalone Hong Kong listing, dropped its 4.0 model on September 28, doubling its maximum video clip length to 30 seconds and adding a suite of creative controls designed to keep it ahead of ByteDance’s competing Seedance product.
The timing is deliberate. With an IPO potentially targeting 2027, every product milestone doubles as a pitch to investors.
What Kling 4.0 actually does
The new model supports more than a dozen reference inputs, meaning creators can feed the system multiple visual cues to guide generation. It also allows for up to 10 keyframes, giving users granular control over how a video unfolds frame by frame.
The previous Kling 3.0 series, released in February 2026, had already introduced native 4K output, so this update builds on an already competitive technical foundation.
A “lite” version of the model is expected in October 2026, aimed at annual subscribers who want capable but less resource-intensive generation.
The money tells the story
Kling’s revenue trajectory has been steep enough to justify the spinoff thesis. The unit hit approximately $500 million in annualized recurring revenue by March 2026, more than doubling from roughly $240 million in December 2025. Q2 2026 revenue exceeded RMB 850 million, a 200% year-over-year increase.

Kling still accounts for less than 3% of Kuaishou’s total revenue.
Kuaishou raised approximately 20.45 billion yuan, roughly $2.8 to $3 billion, in a July 2026 financing round that valued Kling at around $18 billion. That round reportedly drew participation from Tencent, Alibaba, and Baidu.
The company filed plans in May 2026 to spin off Kling as a standalone entity, with a Hong Kong IPO as the end goal.
The ByteDance problem
Kling’s primary rival is Seedance, ByteDance’s own AI video generation tool. Kling has maintained leadership in several industry benchmarks and, crucially, in commercialization. Going from launch in June 2024 to $500 million ARR in under two years is the kind of trajectory that makes product managers at rival companies quietly update their resumes.
What the IPO means for the market
Kuaishou’s decision to spin off Kling rather than keep it as an internal division reflects a broader trend in Chinese tech. Companies are carving out their AI units as standalone businesses to capture valuations that the parent company’s stock price doesn’t fully reflect. An $18 billion valuation for Kling is notable when you consider Kuaishou’s own market cap has fluctuated in a range that doesn’t always reward its AI investments.
A standalone Kling can raise its own funds, recruit with equity compensation tied directly to AI performance, and avoid being dragged down by the cyclical pressures of Kuaishou’s core advertising and live-streaming business.
