In order of size of company, i suspect a more realistic list would be: BitFury is 1st, KnCMiner 2nd, Bitmain 3rd, Cointerra 4th, etc.. this size rating probably works regardless of whether you measure by petahash or revenue. I doubt asicminer is even relevant at this time. They're no longer Huge. They were HUGE when the network was less than 1 Petahash - now they're a minnow - and got left behind when the others designed better chips.
Your 'inside information' is either wrong or old.
You do know that BitFury recently raised $20m on a valuation of $250m, and is thus a $270m valuation company - the largest bitcoin company ever..! and that they're considering an IPO early next year!
BitFury also has the largest private mine of any company. Probably more than 20 PH already. And they claim to be currently powering 40% of the bitcoin mining network (140 PH, thus 40% is 56 PH). That includes both chips they've sold, AND their own private mine.
