As top brands like Cafe Coffee Day and IndiGo set to issue initial public offering (IPOs) soon, the market activity is expected to reach a four-year high.

Several companies have already raised Rs 6,600 crore so far this year and many are planning to "garner another Rs 20,000 crore" through IPOs.

Coffee Day Enterprises Ltd (CDEL), the company that owns Cafe Coffee Day (CCD) chain of restaurants, will issue an IPO on 14 October to raise Rs 1,150 crore, taking the total amount garnered through IPOs in the domestic capital markets to nearly 7,800 crore so far in 2015.

Budget carrier Indigo's parent company Interglobe Aviation is also scheduled to issue an IPO later this month to raise nearly Rs 2,500 crore.

Many other firms are expected to issue public offers in the coming festive season from Dussehra to Diwali. One of them is Infibeam, the first e-commerce firm to get regulator's nod to go for an IPO.

The Securities and Exchange Board of India (SEBI) has already given its approval for 15 firms to go public. Another 17 companies are currently waiting to get a "green signal" from the regulator to issue their IPOs.

Overall, these 34 firms are projected to raise over Rs 20,000 crore through IPOs this year.

"Festive season is approaching, so I expect many companies that are holding their IPO plans and companies that have not hit the capital market despite getting Sebi's approval would definitely plan to go ahead with their public issues," NDTV Profit quoted CNI Research Head Kishor Ostwal, as saying.

In contrast, only 6 IPOs were launched last year to raise just Rs 1,261 crore, while 3 IPOs had hit the market in 2013.
