Why Meta’s $2 Billion AI Agent Acquisition of Manus Was Completely Reversed

Background and Deal Announcement

In December 2025 Meta announced a $2 billion acquisition of Manus, an AI‑agent platform developed by Beijing startup Butterfly Effect. Manus, launched on 6 March 2025, could autonomously screen resumes, find apartments within a budget, and analyze stock correlations among Nvidia, Marvell Technology and TSMC. The product was praised as the next DeepSeek and attracted hundreds of thousands of users, leading to a $75 million Series B round led by Benchmark that valued Manus at $500 million, with participation from Tencent, Hongshan Capital and ZhenFund.

Performance Claims and Strategic Rationale

Manus claimed superior results in direct comparisons with OpenAI’s Deep Research on agent tasks, and by December 2025 its annualized revenue had exceeded $125 million. These capabilities convinced Meta to acquire Manus to fill gaps in its AI‑agent roadmap and accelerate entry into AI hardware and next‑generation computing interfaces.

The “Singapore Strategy” and Its Failure

After the Series B round, Manus moved its headquarters and most staff from Beijing to Singapore in June 2025, a move described in the venture‑capital community as the “Singapore strategy”: Chinese AI firms register abroad to access Western capital, acquisitions and models unavailable in mainland China. The strategy assumes that relocating outside China removes governmental control.

Regulatory Intervention and Deal Collapse

In December 2025 Meta finalized the acquisition, but the Chinese Ministry of Commerce launched a foreign investment security review (FISR) on 8 January 2026. By March 2026 Chinese authorities summoned Manus co‑founders for questioning and prohibited them from leaving the country. On 27 April 2026 the National Development and Reform Commission’s foreign investment security review office issued a notice banning foreign investment in the Manus project and ordering the reversal of the acquisition. This marked the first public denial of a large‑scale AI‑related foreign‑investment deal in China.

Post‑Deal Separation Measures

Following the ban, Meta instituted a two‑way firewall: Manus employees lost access to Meta’s internal systems, code and user data, and Meta prohibited the use of Manus‑related tools in ongoing projects, requiring migration to Meta‑owned infrastructure. Internal memos confirmed a phased shutdown of Manus‑dependent services and a complete asset divestiture.

Manus’ Rescue Plan

With the deal aborted, Manus’s three founders launched a $10 billion buy‑back of all shares from Meta to regain full control. The company plans to establish a compliant Sino‑foreign joint‑venture structure, clarify ownership of technology and equity, and pursue a Hong Kong IPO, with early investors such as Tencent, Sequoia China and ZhenFund cooperating in the restructuring.

Industry Implications

The collapse signals that high‑price cross‑border AI acquisitions are no longer viable shortcuts; future deals must address data security, core AI‑technology sovereignty and stringent foreign‑investment reviews. The episode sets a new regulatory red line for AI‑related M&A, emphasizing that offshore registration alone cannot evade compliance requirements.
