The largest single live poker tournament prize ever won was $18,346,673 by Antonio Esfandiari in the 2012 Big One for One Drop, a high roller event with a $1 million buy-in. This event combined huge stakes with charity support, making it historic. In general, online poker and regular tournaments rarely reach these sums, but multi-million-dollar prizes in super high roller events remain the peak of poker winnings. Such amounts are extreme and highlight both skill and the massive stakes involved.
