Brex hit about $12B in annualized transaction volume at the beginning of 2022. Meanwhile, American Express, in its last earnings conference call, reported receiving $16.2B of transaction volume from SMB customers during Q2’21, for about $65B annualized.


Here’s how American Express’s overall volume mix broke down—SMB was and is typically their biggest customer segment:

  • U.S. Consumer: 28%
  • Intl. Consumer: 14%
  • Corporate Card: 24%
  • Small Business: 34%

American Express also makes money from lending—during the quarter, they lent out $77.8B in total, and about $16.3B to small businesses. That’s $65.2B annualized. Their loan balance, unlike their card mix, skews heavily consumer:

  • U.S. Consumer: 68%
  • Intl. Consumer: 11%
  • Small Business: 21%
