Back From the Dead: Manus Closes $500M-Plus Round After Beijing Unwound Meta's $2B Deal

Six months ago, Manus looked like a cautionary tale. Today, it is one of the best-funded independent AI agent startups in the world.

On October 8, 2026, Butterfly Effect — the Beijing-founded, Singapore-headquartered parent company of AI agent startup Manus — announced that it has closed a funding round of more than $500 million. The round was co-led by Boyu Capital and IDG Capital, with existing investors Tencent, HSG (formerly Sequoia China), and ZhenFund also participating, according to reports from Reuters, CNBC, and Chinese business outlet Yicai. It is the company’s first fundraise since Beijing forced the unraveling of Meta’s $2 billion-plus acquisition — and, depending on the final valuation, potentially the moment Manus re-establishes itself as China’s most valuable startup in the agentic AI field.

A Deal That Died in a Security Review

To understand why this round matters, you have to rewind to late 2025. Manus, a general-purpose AI agent capable of carrying out research, data analysis, and real-world automation tasks with minimal human input, had become one of the fastest-rising products in the AI boom. After moving its headquarters and key staff from China to Singapore, the company agreed in December 2025 to be acquired by Meta for more than $2 billion — a stunning sum for a startup that had reached roughly $100 million in annual recurring revenue within eight months of launch.

Then came the intervention that stunned the industry. On April 27, 2026, a security review office operating under China’s National Development and Reform Commission (NDRC) — the country’s powerful state planner — banned the acquisition and ordered the parties to cancel it, citing national security concerns over the transfer of Chinese-founded AI technology to a US tech giant. It was one of the clearest signals yet that Beijing intends to treat frontier AI agent technology as strategic assets that cannot simply be sold to American buyers.

What followed was a messy, months-long unwinding. Meta began separating from Manus and in June cut the company off from its internal data systems. Manus’s early investors moved to buy the company back at the $2 billion valuation Meta had originally agreed to. In August, Manus said it would resume operating as an independent company — and, as part of the split, deleted user data created on or after December 29, 2025, the date the Meta purchase was signed.

The Round, and What We Know About It

Today’s announcement confirms what had been rumored since mid-September, when The Wall Street Journal and Bloomberg reported that Manus was in talks to raise about $500 million at a valuation of roughly $4 billion. That figure — double the $2 billion price Meta paid, and double the level at which investors bought the company back — would have been aggressive for a company emerging from a forced divorce with its acquirer. Butterfly Effect did not disclose the post-money valuation in its October 8 announcement, nor did it detail precisely how the new capital will be deployed.

What is confirmed is the investor lineup, and it reads like a who’s-who of Chinese capital: Boyu Capital and IDG Capital co-leading, with Tencent, HSG (the firm formerly known as Sequoia China), and ZhenFund — all existing shareholders — continuing to participate. Tencent’s involvement is particularly notable: as far back as July, reports indicated Tencent was positioned to become Manus’s largest shareholder as the restructuring took shape.

Analysts read the close as evidence that the geopolitical storm around the company has, for now, passed. “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,” Dan Wang, China director at Eurasia Group, told CNBC.

Not everyone is convinced the separation is clean. Matthias Hendrichs, a Singapore-based adviser for global AI firms, cautioned CNBC that the deep technical integration between the two companies during the Meta period “does not disappear when the transaction is reversed” — you can separate companies, he argued, “but you cannot make engineers forget what they learned.” It is a reminder that in AI, unlike most industries, the most valuable assets walk out of the building every evening.

Why It Matters

Three bigger stories sit underneath this announcement.

First, the agent land grab is intensifying. Manus competes in the general-purpose agent space — software that doesn’t just chat but executes multi-step tasks — alongside offerings from OpenAI, Anthropic, and a wave of well-funded startups. A $500 million war chest, backed by Tencent’s ecosystem, positions Manus to keep building while rivals burn capital on the same race. Reports from September also indicated the company has explored a Hong Kong IPO as a future path to public markets, giving investors a plausible exit that does not depend on a Western acquirer.

Second, Beijing’s veto is reshaping deal structures. The Manus case has become the reference point for cross-border AI M&A involving Chinese founders. It demonstrated that even a Singapore-domiciled entity with relocated staff remains subject to Beijing’s review if the underlying technology and team are Chinese. The practical consequence is visible in today’s round: rather than pursuing another foreign buyer, Manus’s cap table is now almost entirely Chinese capital — arguably the exact outcome regulators intended.

Third, it’s a test of whether “unwound” startups can thrive. Manus is the highest-profile company to survive a forced acquisition reversal. Its commercial momentum — reportedly nine figures in annualized revenue even before the Meta deal — suggests the underlying product remained sticky through the turmoil. If the independent path works, it will be a template; if it stalls, expect future founders to think much harder before signing with US buyers at all.

For now, the phoenix imagery writes itself: a company that was bought, blocked, unplugged, and bought back has returned to the funding market — and the market answered with half a billion dollars.
