Finextra’s webinar listing, produced with ACI Worldwide, frames fraud intelligence as a potential commercial differentiator for payment acquirers, not just a fraud-prevention expense. It points to merchant concerns about false declines and chargebacks, alongside a lower Visa Acquirer Monitoring Program threshold described as taking effect in April 2026. The listing promotes a discussion of AI, digital identity and network intelligence, but does not report webinar findings or results.
Finextra has promoted a webinar with ACI Worldwide on how payment acquirers can turn fraud intelligence into a commercial offering, as merchants weigh fraud performance and false-positive rates alongside price when choosing providers. The listing also points to a Visa monitoring threshold change described as an April 2026 update, increasing pressure on acquirers to manage fraud and disputes across their portfolios.
The listing describes a shift in how acquirers compete for merchant business. It says merchants are increasingly evaluating fraud performance metrics during provider selection and that false-positive rates and chargeback handling now feature in requests for proposals alongside price. A false positive occurs when a legitimate transaction is declined by a fraud control, potentially costing a merchant a sale.
Finextra cites the Merchant Risk Council as estimating that 65% of merchants in 2026 place their e-commerce false-positive rates between 2% and 10%. The listing also gives projected global merchant losses of more than $231 billion from false positives in 2026, compared with projected card-fraud losses of $39.6 billion. These are attributed estimates and projections in the source, not independently verified figures in the event listing.
The webinar is presented as a discussion of how AI, digital identity and network intelligence could support real-time fraud prevention across channels and payment types. The listing names Marc Trepanier, director of analytics and optimization for fraud and financial crime at ACI Worldwide, as a speaker, with Finextra researcher Sharon Kimathi as moderator. It does not provide a transcript, findings or a record of what the speakers ultimately said.
Fraud Performance Enters Acquirer Sales
The commercial issue is that fraud controls can affect both sides of a merchant’s economics. Weak detection can leave transactions exposed to fraud and disputes, while overly strict controls can reject legitimate purchases. False declines and chargeback handling therefore matter not only to risk teams, but also to merchants comparing payment partners and seeking to protect sales.
For acquirers, a stronger fraud-intelligence offer could help differentiate services and support merchant retention, while also helping manage portfolio-level exposure. The source frames this as an opportunity to move fraud prevention from a cost centre toward a competitive differentiator; it does not provide evidence that any particular tool has produced improved margins or revenue.
The stated Visa threshold change adds a compliance and monitoring dimension. According to the listing, the VAMP ratio combines fraud and dispute counts and divides them by total settled Visa transactions, with the cited threshold moving from 220 to 150 in April 2026. The source does not specify the ratio’s unit or further operational details, so the figures should be understood as reported in the listing rather than a complete account of the program’s rules.

Merchant Metrics and Visa Monitoring
The source is an event announcement, not a report of a new product launch, acquisition or completed industry study. Its central development is the planned panel discussion about how acquirers might commercialise fraud intelligence as financial crime evolves and merchant expectations change. The questions posed include how regulatory and card-scheme pressures affect acquirer accountability and how AI can be used with explainability and operational efficiency.
The listing places merchant false positives and the Visa Acquirer Monitoring Program in the same commercial picture. It says acquirers may ultimately bear liability when merchants cannot absorb losses, and argues that portfolio-wide fraud and dispute ratios have become more important. It names no specific regulatory action beyond the VAMP update and does not describe particular enforcement outcomes.
Its proposed tools are broad categories rather than specified products or deployment plans. AI, digital ID and network intelligence are presented as ways to improve fraud decisions and customer understanding. The announcement does not define how explainability would be measured, identify which data sources are involved, or compare these approaches with existing systems.
Evidence Behind the Commercial Case
The announcement does not report webinar conclusions, case studies or measured financial outcomes. It is therefore unclear whether the approaches discussed have generated additional revenue, improved margins or reduced fraud for particular acquirers. The listing offers a set of questions and promotional claims, rather than evidence resolving them.
Several details behind the cited numbers are also absent: the Merchant Risk Council survey methodology, how the false-positive loss projection was calculated, and the baseline or comparison period for the VAMP figures. The source states that the threshold changes in April 2026, but does not provide the applicable program documentation or explain any exceptions. It also does not give the webinar date, so its schedule and whether the session has already taken place cannot be established from the material provided.
Webinar Discussion and Scheme Rules
The next item identified by the source is the Finextra webinar, hosted in association with ACI Worldwide, featuring Marc Trepanier and moderator Sharon Kimathi. The listing invites readers to register, but gives no date or link details beyond the event page. Any account of the panel’s conclusions would require the session itself, a transcript or a follow-up report.
For acquirers tracking the stated monitoring change, the relevant next step is to consult current Visa Acquirer Monitoring Program guidance for the threshold’s scope, calculation and effective-date details. The event listing flags the April 2026 update but does not set out operational instructions. Until further information is available, the commercial case for fraud intelligence remains a topic for discussion rather than a confirmed outcome.
Key Questions
What is the development in this story?
Finextra has promoted a webinar with ACI Worldwide about how payment acquirers might commercialise fraud intelligence amid merchant demands and monitoring pressures. The listing is an event announcement, not a report of completed results.
Why are false positives a concern for merchants?
A false positive is a legitimate transaction declined by a fraud system. The listing says merchants consider false-positive rates alongside price and chargeback handling when evaluating acquirers, because declined legitimate orders can mean lost sales.
What does the listing say about the Visa threshold?
It says an April 2026 VAMP update lowers the cited ratio threshold from 220 to 150. The source describes the ratio as fraud and dispute counts divided by total settled Visa transactions, but does not provide full program rules or units.
Which technologies are mentioned?
The announcement names AI, digital identity and network intelligence as possible tools for fraud prevention and customer assessment. It does not identify specific products or document measured results.
Are the financial estimates confirmed outcomes?
No. The listing attributes a 2026 false-positive rate estimate to the Merchant Risk Council and presents projected merchant losses and card-fraud losses. It does not include methodology or establish those projections as realized totals.
