The London Stock Exchange has seen off a few suitors lately, including Macquarie Bank, but they just keep coming. Now Nasdaq is offering US$5.1 billion as the international M&A wave sweeps on.

Nasdaq’s offer might not be successful either, but someone will eventually get the LSE after such a steady build up in activity

Of course, a mere $6.7 billion Aussie is hardly anything to get excited about these days, not when Blackstone is paying US$36 billion for Sam Zell’s US property trust, or Freeport-McMoRan bids US$25.9 billion for Phelps Dodge – and that’s just the top couple of takeovers so far this week. It’s only Tuesday.
