Other Investments [Abstract]
Investments in Debt and Marketable Equity Securities (and Certain Trading Assets) Disclosure	OTHER INVESTMENTS We have investments in entities not accounted for under the equity method for which fair values are not readily available. We record these investments at cost (less impairment, if any), adjusted for observable price changes in orderly transactions for the identical or a similar investment of the same issuer. We report the carrying value of these investments in Other assets in the non-current assets section of our consolidated balance sheets. These investments were $1.7 billion and $2.9 billion at December 31, 2020 and June 30, 2021, respectively. The increase from December 31, 2020 primarily reflects an observable event of $902 million (measured using an option pricing model) for our investment in Rivian, reported in Other income/(loss), net on our consolidated income statements. The cumulative net unrealized gain from adjustments related to Other Investments held at June 30, 2021 is $1.2 billion. In July 2021, we purchased $415 million of Rivian’s unsecured senior convertible notes, which will be reflected in our Quarterly Report on Form 10-Q for the quarter ending September 30, 2021.
