summary
Cambridge Analytica was a British political-consulting firm — owned by U.S. hedge-fund billionaire Robert Mercer and led operationally by Steve Bannon as VP — that harvested the Facebook profile data of approximately 87 million users via a personality-quiz app run by Cambridge University researcher Aleksandr Kogan. The harvested data was used to build psychographic targeting models deployed in the 2016 Trump presidential campaign, the 2016 U.K. Brexit "Leave" campaigns (Vote Leave, Leave.EU), and other political operations globally.
the receipts
- The harvest. Kogan's app, "thisisyourdigitallife," was downloaded by ~270,000 Facebook users for academic research (per its disclosed terms). Facebook's API at the time also pulled in data on each user's friends — without those friends' consent. Total reach: ~87 million profiles, including detailed psychographic, demographic, and behavioral data.
- The transfer. Kogan transferred the data to Cambridge Analytica's parent SCL Group, in violation of Facebook's terms of service. Facebook discovered the transfer in 2015, asked SCL to delete the data, and accepted SCL's word that they had. They had not.
- The exposure. Whistleblower Christopher Wylie, formerly Cambridge Analytica's research director, went public via The Observer (UK) and The New York Times on March 17, 2018. The story produced months of global coverage and a UK parliamentary inquiry.
- The bankruptcy. Cambridge Analytica filed for insolvency May 2, 2018 — six weeks after the disclosures.
- Facebook's settlement. The U.S. Federal Trade Commission fined Facebook $5 billion in July 2019 — at the time, the largest privacy-related fine in U.S. history. Facebook also paid £500,000 to the UK Information Commissioner's Office. Facebook's market cap rose roughly $30 billion the day the FTC fine was announced. Investors had priced in worse.
- The principals. Mercer faced no charges. Bannon faced no charges related to Cambridge Analytica. CEO Alexander Nix was banned from being a UK company director for seven years in 2020. Wylie suffered ongoing legal harassment from associated parties.
why this matters to PRIOR
Cambridge Analytica is the foundational case in data-as-weapon. The 2016 elections — U.S. presidential and U.K. Brexit — were each won by margins narrower than the addressable population the firm's targeting models claimed to influence. Whether the targeting actually decided either outcome is empirically debated. What is not debated: a private firm built sophisticated psychographic targeting from non-consensually harvested data, deployed it in the most consequential elections of the era, faced corporate dissolution but no criminal liability for the principals, and left a settled regulatory regime — Facebook's $5B fine — that the market priced as cheaper than expected. The architecture is fully intact.
