Shares of Zip Co plunged as much as 50.5% intraday on October 23 before settling at A$1.46, a 29.5% single-day collapse, after the Australian buy-now-pay-later lender disclosed a coordinated fraud attack on its US operations that disrupted growth and drained millions in emergency costs. The selloff erased roughly A$700 million in market value and raises a pointed question: if a fintech cannot police who's borrowing on its platform, what is the platform worth? Zip's US Fraud Attack Wipes A$1.3 Billion Off Its Market Cap — Is the Buy-Now-Pay-Later Turnaround Story Over?
Shares of Australian buy-now-pay-later lender Zip Co cratered 29.5% to A$1.46 on October 23, hitting an intraday low of A$1.025 — a two-and-a-half-year trough — after the company revealed a coordinated fraud scheme had punched a hole in its first-quarter numbers. The selloff erased about A$1.30 billion ($912 million) from Zip's market value , and it lands on a stock already down 57% year-to-date, threatening to undo a turnaround narrative that drove shares up 352% in 2024.
• Fake Accounts, Real Losses: What Happened in the US
Zip said it found and contained a fraud incident involving coordinated individuals who created new accounts using legitimate credentials to execute unpaid transactions in the US.
The attack resulted in US$7.2 million (A$10.1 million) in cash operating expenses.
Zip has not disclosed the number of compromised accounts, the gross value of fraudulent transactions, or expected insurance recoveries — a silence that leaves the full damage open to speculation.
• The Numbers Looked Fine Until You Subtract the Fraud
Total transaction volume grew 18% year-on-year to A$4.6 billion, total income rose 17% to A$376.1 million, and adjusted earnings rose nearly 20% to A$75.1 million. But that adjusted figure strips out the fraud expense. Including the A$10.1 million hit, reported cash EBTDA rose just 3.4% to A$65 million. Meanwhile, net bad debts — loans unlikely to be repaid — jumped to 1.97% of transaction volume, up from 1.65% a year ago , a metric that worried analysts even more than the headline fraud cost.
• Analysts Want Answers on Whether the Front Door Was Left Open
Citi said the incident "raises concerns on Zip's onboarding controls," while Jefferies said investors need clarity on whether the higher expenses will persist and how Zip will prevent repeats.
UBS flagged the bad-debt miss as sharper than expected , partly because fraud slowed volume growth that would have diluted the ratio.
• September Rebound Offers a Lifeline — If Investors Believe It
Zip said US transaction volume growth accelerated to 41% year-on-year in September as fraud-related disruption eased , and its US customer base stood at 4.7 million as of September 30, up 1.7% from June.
The company has notified authorities and lodged an insurance claim. But credibility is the currency at stake: a lender that cannot verify who is borrowing faces existential questions about risk management — and the market just priced that doubt into the stock at 30 cents on the dollar.
