This ruling is a material procedural loss for Amex — the class action can now proceed in federal court, significantly increasing settlement pressure and litigation costs. Monitor for class certification motions and any settlement discussions; the case is in early stages but the arbitration waiver removes Amex's primary defense. The stock may see modest negative pressure as the market prices in higher litigation risk, but the financial magnitude remains uncertain until discovery progresses.

Executive Summary
The First Circuit affirmed the district court's denial of American Express's motion to stay litigation and compel arbitration, holding that Amex waived its right to arbitrate by refusing to pay AAA filing fees despite repeated warnings, resulting in administrative closure of over 5,000 merchant swipe-fee arbitrations. This ruling allows a putative class action challenging Amex's swipe-fee non-discrimination provisions to proceed in federal court, removing a key procedural barrier for the plaintiffs and exposing Amex to potentially material litigation risk. The decision is a clear loss for Amex and opens the door to class-wide damages exposure, though no damages have been awarded yet.
Court Ruling Details
Key Facts
- First Circuit affirmed district court ruling that Amex waived its right to compel arbitration by refusing to pay $3,150 per case in AAA filing fees for 5,155 merchant arbitrations.
- Amex's nonpayment led AAA to administratively close all 5,155 arbitrations in February 2024 after months of warnings.
- The ruling allows a putative class action challenging Amex's swipe-fee non-discrimination provisions to proceed in federal court.
- The case involves thousands of small merchants alleging Amex's swipe fees (~3% per transaction) and non-discrimination rules force merchants to accept Amex at higher cost.
- No damages have been awarded; the ruling is procedural (waiver of arbitration rights), not a final judgment on the merits.
Financial Impact
No damages awarded yet. The ruling removes Amex's ability to force individual arbitration, exposing it to class-action liability on swipe-fee claims involving thousands of merchants. Swipe fees are ~3% of each Amex transaction; total potential exposure is not stated in the opinion.
Risk Factors
- Class certification would dramatically increase Amex's settlement exposure on swipe-fee claims across thousands of merchants.
- Adverse ruling on merits could force Amex to modify its non-discrimination provisions, potentially reducing swipe-fee revenue.
- Appeal to Supreme Court is possible but unlikely to succeed given the fact-specific waiver finding.
