The flood of tiny foreign companies listing on US stock exchanges has basically turned into a trickle. Regulators and the exchanges themselves cracked down hard on pump-and-dump schemes, and the numbers show it worked.
A microcap is just what it sounds like - a very small company, often raising less than $25 million. The largest single IPO in that period raised just $40 million. All microcap IPOs in the first half of 2026 raised less than $300 million, compared to $1.6 billion in all of 2025.
The decline is particularly pronounced among Asian firms. And those two have not done well.
The SEC has also suspended trading for more than a dozen foreign stocks. Among them: Indonesia-based online travel agent NusaTrip Inc., Hong Kong hotpot chain Happy City Holdings, and Singapore-turned-China company Smart Digital Group Ltd.
A wave of pump-and-dump schemes directly prompted the regulatory crackdown. The pattern goes like this: promoters use social media to hype up a tiny stock, often one from Asia with little real business. Retail investors pile in, the price shoots up, and then the promoters dump their shares. The stock collapses, and regular people lose their money.

The SEC, the Financial Industry Regulatory Authority (FINRA), and Nasdaq all tightened the rules. In December, Nasdaq implemented new regulations that expanded its ability to block listings when it suspects irregularities.
Jamie Selway, head of the SEC's trading and markets oversight division, said market participants sent a clear signal that action was required.
"There was a resounding message from market participants that there was a problem here and that something needed to be done," Selway said.
"With the SEC's statements on these matters and the Nasdaq's efforts to tighten its listing program, the writing is on the wall for both the issuers and those trying to manipulate the stocks," said Mark Donohue, a previous SEC policy adviser and founder of Thirty4 Advisory.
Even big financial firms like Charles Schwab Corp. and Citadel Securities had warned about the risks of these microcap stocks.
The crackdown appears to have worked. While stopping fraud is good for everyone, there is a real concern that the new rules are scaring off legitimate small companies too.
Takuma Segawa, the chief financial officer of Micware Co., one of the two Asian companies that did manage to list this year, described the experience as scary for a company new to US markets. "As a Japanese company, we are new to the US stock market. And it can be very scary," Segawa said.
In March, Green Circle informed shareholders that the NYSE had flagged "unusual market activity" and said the company would keep watching trades and share any important updates as necessary.
Increased regulatory attention resulted in trading suspensions for over a dozen companies last year, with several facing potential delisting. Among them was QMMM Holdings Ltd., a Hong Kong company that provides digital advertising and virtual avatar services. Its stock skyrocketed nearly tenfold in under three weeks after it revealed plans to enter the cryptocurrency space.
The SEC halted trading last September, pointing to possible social media manipulation, and Nasdaq subsequently initiated proceedings to delist QMMM. QMMM, which has not been charged with any misconduct or involvement in a stock manipulation plot, intends to contest the delisting process, according to a securities filing.
