Wow. Crazy. Google is starting to leverage their position. They now selling 12.8x this buy in corporate bonds. I think this is the beginning of many plays by Google/Alphabet.
Alphabet is selling some record amount of corporate bonds, which OP states they're using to finance this purchase (and that they raised 12.8 times this amount so there's plenty left to make more acquisitions).
Probably the implication is that with really cheap funding (bonds) they can swash buckle across corporate america and buy stuff? It's most likely a coincidence. Google had $120B of cash on its balance sheet at 12/31/19.
