I'm not sure if you consider Coinbase a major bitcoin company yourself, but I think they qualify.
If I was to make a prediction, everyone will be running segwit2x or another client faking segwit2x support, to get segwit passed by Aug 1st. Then once October comes along we'll have another fight over the actual blocksize hardfork.
That doesn't look like a very good proof. If coinbase plans to adopt segwit2x, why haven't they released an announcement? I wouldn't trust that wiki list very much.

And don't trust the wiki, no need to. Trust the hash power. The NYA signal was just a promise, so don't trust that one. But the BIP91 signals are coming in already. Just need to get that over 80% for just over 2 days. Then we'll see the original segwit signals jump to the 95%+ it needs.
But the truth is, you don't have to worry about finding any support proof or anything. We'll know what happens over the next week or two for sure. I don't care whatever direction it goes in, I just want it to go smoothly.

90% are signalling the NYA intent to support Segwit2x. Since the software release 20% have signalled with segwit2x blocks.
