Several years ago, AMD spun off their chip manufacturing infrastructure into a company, which was named GlobalFoundries, and became a fabless integrated circuit designer. This transaction meant that AMD would be free to shop around when they needed something printed, and they wouldn't need to pay for the upfront expenses. That burden would be placed on the shoulders of stakeholders in GlobalFoundries, and of course the revenue they acquire from their larger pool of customers.

Speaking of their stakeholders, GlobalFoundries is wholly owned by Advanced Technology Investment Company, which is owned by Mubadala Development Company, which is owned by the government of Abu Dhabi. GlobalFoundries merged with Chartered Semiconductor and was actually paid by IBM to acquire their fab business, at a reward of $1.5 billion USD and binding IBM to a ten-year exclusivity deal for server processors, which helped bolster the company. Oil prices have been fluctuating though, and sources tell Bloomberg that Abu Dhabi is interested in selling some or all of GlobalFoundries at a valuation of around $15-20 billion USD.
The report stops there, without declaring any potential candidates, but speculation doesn't. A lot of it just sounds like listing names who have lots of cash. If the source is even accurate, we don't know who are involved or how serious they are.
