Bharti Airtel is planning a significant expansion of its data centre business, targeting a 25% market share over the medium term, while indicating that radio network spending has moderated after the peak phase of the 5G rollout, the company management said during a post-earnings call with analysts. Airtel’s data centre arm Nxtra is targeting a capacity of around 1 gigawatt over the next three to four years, a sharp increase from the current 120–130 megawatts. At present levels, Nxtra has an estimated market share of about 12% in a fragmented domestic data centre market.
