US investment firm Bain Capital is reportedly preparing to divest the Chinese data centre operations of WinTriX DC Group in a deal that has could exceed US$4 billion.

Reuters said that sources familiar with the matter confirmed the sale value, with advisers having initiated preliminary talks with potential buyers.

WinTriX’s China operations are expected to generate around 4 billion yuan (US$551.92 million) in Ebitda in 2025, sources added.

The potential sale comes after Bain Capital privatised Chindata Group, now WinTriX, in a $3.16 billion deal in 2023, after completing the acquisition in 2019.

Immediately after the acquisition, Chinadata Group merged with Southeast Asian data centre operator Bridge Data Centres, with the privatisation initially combining the two companies. Reuters reported that the businesses were subsequently split again under WinTriX.

The deal comes at a time of growth for the data centre market, driven by the rise of artificial intelligence (AI) and cloud computing, with forecasts indicating the upwards trajectory to continue in China.

According to Technavio, a market research firm, the data centre market in China is expected to grow by $274.39 billion between 2025 and 2029.

The market is estimated to grow at a compound annual growth rate (CAGR) of 38.3 per cent during the forecast period.

The growing demand for hyperconverged data centres is driving market growth, with a trend towards the use of server disaggregation to improve utilisation rates, the company said in its report.
