Thursday, it was rumors of a potential bid for Anadarko (NYSE:APC) by BHP Billiton (NYSE:BHP). BHP Billiton is certainly hungry for acquisitions, particularly large ones that add substantially to its presence in commodities that it is already familiar with. From this point, a potential bid for a mid-tier oil and gas producer like Anadarko might have some merit, particularly after the Australian outfit's recent failed effort to acquire Potash Corp (NYSE:POT) and failed attempt to merge its massive iron ore operations in Western Australia with peer Rio Tinto (NYSE:RIO). Rumors of the bid first surfaced in the UK press, quickly spreading across the globe. The rumor suggests a bid of $90 per share, compared to Anadarko's share price today of almost $77.
