Following concerns about privacy of its citizens, the European Union enacted the General Data Protection Regulation (GDPR), forcing websites serving European citizens to adhere to certain standards of user consent, data transparency, and user information access and erasure.
Big companies especially have spent a long time and much money preparing for the law, which came into effect in May, 2018. Several large companies have already received claims that they are not in compliance with the regulation.
This question resolves positively only if a European or US company with a market cap of over 50 billion nominal USD is fined at least 1 million nominal USD (cumulatively) for GDPR violations by end-of-day Dec 31, 2021 Eastern Time .
The market cap requirement (as specified by the intraday value on, for example, Yahoo finance) can be met at any point in time by the end date specified above for the company to qualify. "European or US" can be determined using e.g. Forbes' list or comparable data source.
