- Prevent 2.0, Chargeflow’s new AI model, catches 10 times more fraud and abuse than the previous generation, scanning every order for fraud and abuse, not just stolen cards.
- Chargeflow also launched the Chargeflow Data Lab, whose first reports draw on about 3 million disputes to show how chargebacks change over Black Friday and when they arrive.
- Prevent 2.0 is now live for Shopify merchants ahead of Black Friday, with the first 1,000 scanned transactions free for merchants new to Prevent.
NEW YORK, Oct. 22, 2026 /PRNewswire/ — Chargeflow, the AI chargeback platform used by more than 20,000 merchants, today announced Prevent 2.0, the new AI model behind Chargeflow Prevent, its fraud scanning for Shopify merchants. Prevent 2.0 catches 10 times more fraud and abuse than the previous generation.
Most disputes don’t claim fraud at all. The buyer says it never arrived, wasn’t as described, or that they didn’t mean to renew. Prevent 2.0 scans for those too. Those claims grow over Black Friday. Of about three million disputes analyzed, one in three chargebacks over Black Friday weekend 2025 said the order never arrived, up from one in five in a normal week, according to early reports from the newly launched Chargeflow Data Lab.
Prevent scans every order for fraud and abuse after checkout and blocks risky orders before fulfillment. Nothing changes at checkout. Every merchant already running Prevent automatically moves to the upgraded protection of Prevent 2.0, with nothing to switch on.
What’s new in Prevent 2.0
- A new AI model. Every decision now comes from the new model, made after checkout and before the order ships.
- Stolen cards, now covered. Prevent scans for third-party fraud in the same decision as friendly fraud.
- Suspect delivery patterns. It spots signs such as different names shipping to the same address.
- Sharper on abuse. Prevent is better at spotting known repeat disputers: buyers with a history of disputing orders they received, even on their first order with a store.
Every decision draws on Chargeflow Network Intelligence, the dispute data Chargeflow sees across more than 20,000 merchants. That lets Prevent flag a buyer with a history of disputes at other stores, even on their first order with a new one.
“We built Chargeflow so that when merchants deliver, the revenue they’ve earned stays theirs,” said Avia Chen, co-founder, chief product officer and chief marketing officer of Chargeflow. “We believe every merchant should have this protection, and that it should come switched on rather than as a project. Prevent 2.0 is how we deliver on that for Black Friday 2026.”
Black Friday changes what customers dispute
The Data Lab’s first reports draw on a study of about three million disputes across the last three peak seasons. Over the 2025 Black Friday to Cyber Monday weekend, 34.7% of chargebacks said the order never arrived, the claim card networks call “item not received.” In a normal week, it was 19.9%. The same shift appeared in 2023, 2024 and 2025.
Fraud claims moved the other way. Their share of chargebacks fell to 27.2% over the weekend, from 37.8% in a normal week. On the busiest weekend of the season, “never arrived” claims outnumbered fraud claims.
“Never arrived” is a claim merchants can answer: those disputes that went to a decision were won about 1.5 times as often when backed by strong evidence, such as proof of delivery.
“Every merchant sees only its own chargebacks. Chargeflow sees them across more than 20,000 merchants. Starting today, the Chargeflow Data Lab publishes what that view shows us,” said Chen. “When everyone works from the same facts, the bad actors lose their edge.”
Pricing and availability
Prevent 2.0 is now live for Shopify merchants. Merchants new to Prevent get the first 1,000 scanned transactions free through Dec. 31, 2026. After that, Prevent costs $0.10 per scanned transaction for each order or subscription renewal it scans.
Merchants new to Chargeflow can install Chargeflow from the Shopify App Store and activate Prevent. Existing Chargeflow merchants can activate Prevent in their account.
