The largest class action settlement in history is the 1998 Tobacco Master Settlement Agreement — worth approximately $246 billion paid by major tobacco companies (Philip Morris, RJ Reynolds, Lorillard, and Brown & Williamson) to 46 US states. This multi-decade payout dwarfs every other settlement in history.

What These Settlements Paid Per Person
Large settlement totals don't necessarily mean large individual payouts. The T-Mobile data breach settlement ($350 per person for some claimants) paid significantly more per person than many larger aggregate settlements. Individual payouts depend on how many people file claims and the settlement structure.
The Equifax settlement is a notable example: despite a $700 million total, the $125 cash payment option for affected individuals was reduced to approximately $5.21 because 147 million people filed claims. Most individuals instead opted for the extended free credit monitoring.
