Investors can't wait for buzz-worthy Pandora, Groupon IPOs

Interest in Inteet initial public offerings seems to only be heating up as two hotly awaited IPOs edged closer to their debuts.

Web radio provider Pandora boosted the amount it's looking to raise by 43% to $176.2 million in response to high demand. The company will offer 14.7 million shares for $10 to $12, according to a regulatory filing.

The company had previously planned to sell 13.7 million shares for $7 to $9.

Meanwhile, daily deals website Groupon asked six more banks to help underwrite the sale of its shares, Bloomberg News reported, citing two people familiar with the matter.

The banks included Barclays, JPMorgan Chase and Citigroup. Morgan Stanley, the Goldman Sachs Group and the Credit Suisse Group are leading the IPO, a June 2 filing said. Banks are scrambling to cash in on lucrative fees from Inteet IPOs.

Shares of professional networking website LinkedIn doubled in their first day of trading last month, further stoking demand for Web company IPOs.

Things weren't going quite as well, however, for Ally Financial. The auto and home lender put off plans to start marketing its IPO until equity markets improve, major news wire services said, citing people familiar with the plans.

Ally, previously known as GMAC, had been expected to try to raise $5 million to $7 million with an IPO at the end of June.

The money would have helped pay back some of the $17.2 billion the govement poured into the company - General Motors' former financing arm - during the mortgage crisis. The govement still owns about three-quarters of the company.

Ally's IPO is now expected to take place at some point in late summer.
