NYSE Group ( NYX) and Goldman Sachs ( GS) each took 5% stakes in India's biggest stock exchange, the National Stock Exchange.

Private equity firm General Atlantic and the Softbank Asian Infrastructure Fund each took 5% stakes as well, the Indian exchange said Wednesday.

"We are pleased to welcome the NYSE Group and other new stakeholders in NSE," said CEO Ravi Narain. "In a rapidly integrating world of financial markets, this timely partnership brings together the strengths of institutions from North America, Europe and Asia. This alliance marks a significant milestone for NSE in developing a place for itself in the emerging global scenario. The global financial investors are amongst the most pedigreed institutions in the world, and will contribute to building value in the NSE."

The news comes amid a wave of exchange consolidation around the world, with the NYSE and rival Nasdaq ( NDAQ) each looking to make big overseas acquisitions this year.
