They aren't too big to fail, but they're never going to fail, because the US government would never let it happen.One might argue Intel are too big to fail, they are not, no one is, Nokia used to think that, if this trend doesn't change, drastically Intel will run out of money and rack up debts, they are already $53 billion in debt, if they rack up much more of it they will not be able to service that debt and that's when it all goes wrong.
I don't think Intel are in any peril yet.
The subsidies from western governments are already enormous and dwarf their recent losses. It is possible that some shareholders would lose money in a buyout, especially retail investors, but the big money would be bailed out by taxpayers and a cut price share sale would return any losses and more, the same way it has been done with banks.
