Qualifying companies are Meta, Apple, Amazon, Netflix, Google, Tesla, and Twitter. The company must announce that one of its major services (not an experimental or gimmick service) will take payment in a crypto token which can be easily exchanged from most major cryptocurrencies on at least one large exchange without an intermediate fiat step. If a company has announced this, they do not need to have implemented the payment system by the resolution date for the question to resolve positive, as long as they are still widely expected to do so. The state of world on 1/1/24 is key, if a company announces but then backtracks before then, it will not qualify. Resolution depends on Scott Alexander's judgment.
