The company picked up over 64.51 lakh shares at a market price of Rs 38 per share, company officials said.
Asked whether it was a part of Bharti's diversification into the financial sector, the officials declined to comment.
Earlier last year, Bharti had formed a joint venture with a UK-based company to export fruits and vegetables.
Bharti is also a strong contender for taking a project for modernisation of Delhi and Mumbai airports in association with Changi airport of Singapore.
