Given musk’s history (“funding secured” to take Tesla private; trying to back out of buying twitter), OpenAI can make a reasonable case that he’s full of shit and it’s not a real offer.
He tried to claw back Twitter because tech stocks tanked, but he did have the funding to make the purchase (obviously). I don't think this is a good example. Besides, this is a real consortium, not a oneoff Tweet.
Considering an offer in relation to a valuation includes how likely the deal is to go through. That Elon has tried to pull out of a major purchase in bad faith definitely factors in.
That doesn’t make the offer worth $0, but it’s not $97.4bn
