Shein’s app runs on the tricks the FTC calls ‘dark patterns.’ Now the FTC is investigating.

Shein wanted its Hong Kong listing to be about growth. Instead, the filing meant to sell that story revealed a US regulator is investigating the company, and Shein will not say why.

The disclosure sits in the draft prospectus for Shein’s planned IPO, Reuters reported. Its US business, the filing said, is under investigation by the Federal Trade Commission. An FTC spokesperson confirmed a consumer-protection inquiry. This appears to be the probe’s first public disclosure.

A probe with no stated target

Shein did not say what the FTC is looking at. It said only that it is cooperating, and that it cannot predict the outcome or the timing. The warning it gave investors was blunter. Any resolution, it wrote, could force “significant monetary payments” with “a material adverse effect on our financial condition.”

The FTC polices unfair and deceptive business practices. It has taken on other marketplaces and platforms, from Amazon to Coupang, over how they treat their customers. It has also pressed firms over how their products lock people in. Its cases have covered hidden fees, misleading prices, awkward cancellations and the mishandling of data. None of that reveals what the FTC alleges here. It does map the territory the agency works in.

The dark-pattern problem

One corner of that territory is hard to ignore. The FTC has spent years going after “dark patterns,” CNBC noted. These are the design tricks that nudge people into spending or handing over data. In a 2022 report, the agency named the countdown timer as a classic example.

Shein’s app runs on exactly these mechanics. It uses countdown timers, gamified discounts and limited-time flash sales. Each is designed to turn browsing into buying before the shopper stops to think.

The FTC has not said its probe concerns any of this. But it is an uncomfortable overlap for a company about to ask public investors for money.

The worst possible timing

The disclosure lands at the end of a long, bruising road to market. Shein tried to list in New York, then London, and only reached Hong Kong after Beijing’s regulator cleared it this month. Its target valuation of $40bn to $50bn is a fraction of the roughly $100bn it commanded in 2022. Some investors have reportedly pushed for closer to $30bn.

The business underneath has weakened too. Shein swung to a $99m loss in the first quarter, from a $395m profit a year earlier. The reversal followed the US scrapping the “de minimis” exemption that let cheap parcels enter duty-free.

US revenue fell about 14% to $2bn. The EU has since added its own charge on low-value parcels, Forbes reported. A consumer-protection probe from its largest market is the last thing Shein needed as it finally tries to sell the story.
