Twitter has raised $1.3bn from the debt markets, less than a year after its flotation, raising speculation that it is amassing a war chest for acquisitions. So far, its
acquisitions have been on a relatively small scale. In May, it paid $134m for Gnip -- a company that provides data about social media -- and shortly before its market debut, mobile publishing
platform MoPub, for $350m.
Wednesday's move stoked expectations that it will step up the pace of its acquisitions, and also continue hiring top-flight engineers.
