US domestic initial public offerings raised $6.27bn during the second quarter, according to a report issued by IPO Monitor. The number of companies launching IPOs during the quarter slipped to 110, down from a record 250 a year ago, including a significant drop-off for internet firms. Although fewer IPOs were launched in Q2, IPO Monitor notes a trend toward larger offerings with the $6.27bn raised easily eclipsing the total of $5.66bn from last year’s record quarter. Rambus Inc, Mountain View, California developer of high-speed memory chip interface technology, took top honors for the most successful IPO of the quarter (CI No 3,161), climbing 288% from the offering price of $12 to $46.50 on June 30.

Peapod Inc, the online grocery store, dropped 30% after a brief surge on the offering (CI No 3,181).
