TL;DR: Chargeback fraud is rising alongside e-commerce, with Mastercard projecting global chargeback volume above 335 million by 2026, a 42% increase from 2023, while merchants paid an estimated $100 billion in chargebacks in 2023, according to Sift. The real security challenge is not just dispute handling but identity and intent verification at transaction time, where first-party fraud and account takeover blur together.
Editorial analysis by NHI Mgmt Group, based on content published by Sift: “How to Prevent Chargeback Fraud in Online Stores”.
By the numbers:
- Global chargeback volume will exceed 335 million by 2026, a 42% increase from 2023, according to Sift.
- E-commerce sales reached $6 trillion in 2024, expanding the transaction surface for disputes and fraud, according to Sift.
- Nearly half, or 43%, of U.S. consumers admitted to disputing legitimate charges, according to Sift.
Key questions
Q: What breaks when chargeback fraud is not detected at transaction time?
A: When merchants rely on post-dispute handling alone, they lose the best opportunity to stop abuse before delivery.
Q: Why do online merchants face more chargeback abuse than physical retailers?
A: Online merchants have less contextual evidence at the point of purchase.
Q: What are the signs that chargeback controls are not keeping pace with fraud patterns?
A: Warning signs include rising dispute volumes, higher rates in specific industries or issuer bins, repeated disputes from the same consumers, and shifts in behavior such as VPN use, IP anomalies, or multi-account activity.
Practitioner guidance
- Strengthen transaction-time intent checks Use device, velocity, location, and payment-history signals to score intent before fulfilment, especially for high-risk orders and digital goods.
- Separate first-party abuse from true fraud Build decision rules that distinguish disputed legitimate purchases from stolen-card transactions, because the mitigation path and evidence set are different.
- Tighten controls for subscriptions and digital fulfilment Require stronger verification where goods are intangible or recurring, since post-sale evidence is weakest in those models.
Bottom line: Chargeback fraud is increasing because e-commerce gives fraudsters more ways to exploit the gap between purchase approval and dispute resolution.

Chargeback fraud is fundamentally an intent-verification problem, not a payments-only problem. The article shows that merchants are being asked to distinguish legitimate refunds, first-party abuse, and stolen-card fraud from the same transaction record. That pushes the issue into trust and identity governance, because the core question is whether the purchaser is entitled to the transaction outcome. Practitioners should treat intent verification as part of the control plane, not as a back-office dispute function.
A few things that frame the scale:
- Nearly 60% of companies reported that fraud losses were still increasing in 2025.
A question worth separating out:
Q: What happens when merchants treat fraud only as a chargeback problem?
A: When fraud is treated only as a chargeback issue, merchants miss the wider operational cost. They still lose the product, absorb payment and review expenses, and often damage loyalty by declining legitimate customers or failing to detect abuse early. The result is a narrower view of risk that underestimates how fraud affects revenue, operations, and repeat purchase behavior.
