China's Big Fund becomes SMIC's third-largest shareholder in $6bn Star Market deal
Synopsis
Key Takeaways
China's National Integrated Circuit Industry Investment Fund, widely known as the Big Fund, has become the third-largest shareholder of Semiconductor Manufacturing International Corporation (SMIC) — the country's largest wafer foundry — after the completion of a landmark 40.6 billion yuan (US$6 billion) acquisition deal on 25 June 2026, marking the biggest merger and acquisition transaction ever recorded on Shanghai's Star Market.
The Deal Structure
SMIC issued 547 million new shares to five shareholders of its subsidiary, Semiconductor Manufacturing North China (Beijing) Corporation (SMNC), in exchange for a 49 per cent stake in the unit. The transaction, first proposed in August 2025, was formally completed this week after months of regulatory and shareholder approvals. The five beneficiary shareholders include the Big Fund, which now ranks among SMIC's top owners.
Why It Matters
The deal consolidates SMIC's grip over a strategically critical manufacturing node. SMNC, founded in 2013, specialises in 12-inch wafer foundry services and has served as SMIC's primary production base in Beijing. In an April 2026 filing, SMIC stated the transaction would 'further improve the company's asset quality, enhance business synergies and promote long-term development.'
Lu Kelin, founder of consultancy Lukedao Tech, offered a pointed read of the move: 'SMIC's acquisition of minority stake in SMNC is essentially aimed at addressing its production capacity shortage and converting the premium from external shareholders into internal strategic benefits.'
The Competitive Backdrop
The transaction arrives as Washington continues to tighten export controls on advanced semiconductor equipment and chips destined for China. Beijing's response has been to deepen state financing of its domestic chip supply chain, with the Big Fund acting as the primary vehicle. By folding SMNC's capacity directly into SMIC's balance sheet, the state effectively converts a partially external asset into a fully integrated national resource.
What's Next
With SMNC's 12-inch wafer capacity now more tightly integrated, SMIC is positioned to accelerate output for domestic chip designers who have been squeezed by both global supply constraints and US-imposed procurement barriers. Analysts and industry observers will be watching whether the expanded capacity translates into meaningful yield improvements at advanced nodes, and whether further consolidation of China's fragmented foundry landscape follows this record-setting precedent on the Star Market.
