Strong demand for the sale, the biggest by an Asian borrower so far this year, allowed Alibaba to significantly tighten the prices it offered. Orders for the bonds totalled about $40 billion, bankers said.
The five-tranche deal involved bonds maturing at points from 5.5 years to 40 years. The range allows China's biggest e-commerce company to develop a yield curve which peers could use to determine the attractiveness of maturities when issuing their own debt, analysts said.
"The tech sector (for bonds) is small in Asia and this sets a precedent for others to follow," said CreditSights analyst Sandra Chow.
She said Alibaba, Baidu Inc and Tencent Holdings Ltd are trailblazers in Asia, where investors were generally less familiar with tech industry bonds than in the United States. Alibaba's latest sale is its second, whereas Baidu and Tencent are seasoned issuers.
"It does help build up the market and the range of maturities will create better trading liquidity across the curve," said Chow.
The tranches for the 5.5-, 10-, 20-, 30- and 40-year maturities were priced at 73, 108, 118, 138 and 158 basis points (bps) over U.S. Treasuries. In the secondary market the bonds were trading at 63-62, 106-105,106-103, 125-122 and 144-141 bps, respectively.
The deal pricing was already far tighter than initial indications of about 100, 125-130, 140, 160 and 180 bps respectively.
"Alibaba is a fundamentally sound company with a dominant market position and solid positive cash flows," said Alaa Bushehri, portfolio manager for emerging market debt at BNP Paribas Asset Management.
Alibaba holds 68.1 billion yuan (£7.66 billion) in net cash, meaning its total cash exceeds its total debt. Analysts said however that it was wise of the company to borrow.
"Raising debt when they can is smart - they could use the money for more investments and acquisitions in future. They have talked about FMCG (fast-moving consumer goods), food or logistics, so we could see purchases there," said Chow.
The company sold $700 million in 2.800 percent bonds due 2023, $2.55 billion in 3.400 percent bonds due 2027, $1 billion in 4.000 percent bonds due 2037, $1.75 billion in 4.200 percent bonds due 2047.
It also sold $1 billion in 4.400 percent bonds due 2057 - a time frame more than twice as long as the company, founded in 1999, has been in existence.
Alibaba has invested upwards of $9.3 billion in brick-and-mortar stores since 2015. Earlier this month it said it would invest $2.87 billion for a major stake in China's top hypermart operator, Sun Art Retail Group Ltd, as part of a wider push into offline retail.
Morgan Stanley, Citigroup, Credit Suisse, Goldman Sachs and JPMorgan are the bookrunners for the bond, which is rated A1/A+/A+ (Moody's/S&P/Fitch), the same ratings as the issuer.
