Manus Raised $500 Million After China Blocked Its Sale to Meta
The AI agent startup is back as an independent company, freshly funded and building its own technology stack, even as its cautionary tale about cross-border dealmaking lingers.
Key points
- Manus parent Butterfly Effect raised more than $500 million in its first funding round since Chinese regulators blocked Meta's $2 billion acquisition of the company.
- The round was led by Boyu Capital and IDG Capital, with follow-on investment from Tencent and ZhenFund, among existing shareholders.
- Bloomberg reported last month that the deal would value Manus at roughly $4 billion, making it the most valuable AI agent startup in China.
- Since the split, Manus has shipped Manus 2.0 on a new in-house engine called Cascade, plus a standalone personal-agent app named Cue.
- Meta has pressed ahead with its own agent product called Muse, built on the open-source framework OpenClaw.
In early 2025, Manus looked like the template every Chinese AI startup wanted to copy: launch in China, win a marquee Silicon Valley backer (Benchmark), relocate to Singapore, and sell to a US tech giant at a large premium. Meta announced a $2 billion acquisition in December 2025. Then Beijing stepped in.
China's National Development and Reform Commission issued a directive with no clear precedent, one that specifically prohibited foreign investment in the Manus project. Meta, which had already begun weaving Manus engineers and technology into its own systems, had to unwind the deal.
What does a $500 million raise actually signal?
Investors do not think the China block was a death sentence. Butterfly Effect confirmed Thursday that Boyu Capital and IDG Capital led the round, with Tencent, HSG and ZhenFund contributing as existing shareholders. No post-funding valuation was disclosed, though Bloomberg had reported the roughly $4 billion figure.
"The fundraising shows that the short-term fallout of the Meta case has been contained and investors are willing to back Manus as an independent company," said Dan Wang, China director at the political-risk consultancy Eurasia Group.
The raise is also a data point for the wider AI agent market. An AI agent is software that carries out multi-step tasks on its own, such as booking appointments or managing emails. That category has faced questions about commercial durability as underlying AI models get cheaper by the month. A half-billion-dollar bet suggests appetite hasn't died.
This is the 20th funding story AI2Day has covered since 17 July 2026, and the Manus situation stands apart: a company that had its strategic path legislated away and still attracted institutional capital at scale.
What has Manus actually built since the split?
Two products. Manus 2.0 runs on Cascade, a new in-house execution system that replaces the architecture Meta was integrating. The company also launched Cue, a personal-agent app where each AI agent gets its own email address, phone number and mobile wallet, letting it act in the world with real contact details. For ordinary users, that means an AI that can make calls and receive messages on your behalf, not just simulate doing so.
Meta has not stood still. It launched Muse, its own personal AI agent, in early September 2026, built on the open-source framework OpenClaw. Our story on 23 September found that Muse hit 900,000 downloads in its first week, and we followed that with a look at the Muse Charm hardware companion on 27 September.
The honest read: Manus is a direct competitor to the company that tried to buy it. That's the part the headline doesn't fully capture, and it's the part worth watching.
Common questions
Why did China block the Meta deal in the first place?
China's National Development and Reform Commission issued a ruling prohibiting foreign investment specifically in the Manus project. The exact national-security or policy reasoning was not made public, but the effect was immediate: Meta had to stop its integration and return the company.
What does this mean for ordinary users of Manus or Meta AI?
Users of Manus now interact with a fully independent company building its own technology. Meta users get a separate agent product called Muse. The two are competitors, not the same system under different names.
