Brewing giant Anheuser-Busch InBev NV is planning to sell roughly $30 billion in bonds Wednesday in a deal that would rank as the second largest on record, underscoring the strength of the corporate-debt market despite turmoil in certain sectors. Some investors and analysts say the company, which is buying rival SABMiller PLC for more than $100 billion, could ultimately sell about $55 billion in new bonds to help pay for the acquisition.
