Stripe analyzes three fast-growing types of first-party fraud detected across its network from late 2025 to early 2026.
- •Account abuse: 7.4% of AI company sign-ups are implicated in suspected multiaccount abuse, where users create multiple accounts to exploit free tiers and compute resources.
- •Free trial abuse is accelerating, with AI startups offering self-serve free trials seeing 10x more abuse attempts than enterprise AI solutions; Stripe Radar now predicts trial abuse with 90% accuracy.
- •Refund abuse causes an estimated $100 billion in global losses annually, including wardrobing and sophisticated multi-account schemes to bypass refund limits.
- •Traditional prevention methods like blocking virtual cards are no longer effective as legitimate users increasingly rely on them for privacy.
- •Stripe is rolling out new Radar features for account registration screening, free trial abuse detection, and refund abuse prevention.
