From the Boston Globe:

Amazon already has a large and growing presence in Kendall Square, but is eying downtown Boston in part because it has cheaper rents and more available space than in nearby Cambridge. It would also join a string of tech companies that have set up shop downtown, helping to reinvent the traditional business district as a hub for a new industry.

“Downtown Boston already has tremendous street cred in the tech world,” said Brendan Carroll, head of Encompass Real Estate Strategy, which tracks Boston’s office market. “But Amazon moving in would be a really big thing.”
