Alibaba Group Holding Ltd (IPO-BABA.N) plans to increase the size of its U.S. The Chinese e-commerce company launched the IPO last week and had enough investor demand to cover the entire deal within two days, people familiar with the process said last week. Alibaba could set a new record for the world’s biggest IPO if underwriters exercise an option to sell additional shares to meet demand, pushing it as high as $24.3 billion and overtaking Agricultural Bank of China Ltd’s $22.1 billion listing in 2010.
