Here's something you don't see every day: a billionaire founder posting receipts from his teenage years to prove success isn't instant. Shayne Coplan, who created blockchain prediction market Polymarket, recently shared a pretty extraordinary piece of his origin story on social media.
"What people call an 'overnight success' takes a decade," Coplan wrote on Dec. 2 on X, before dropping a screenshot of an email he sent to the Securities and Exchange Commission back in October 2013. The kicker? He was 14 years old.
The Email That Started It All
"My name is Shayne Coplan. I'm a high school sophomore here in Manhattan," the email began. "I'm creating an ECN based stock exchange, and my first line of task is to make sure my idea is totally legal, and can comply with SEC regulations."
The teenage Coplan continued: "I plan for this to be a registered National Securities Exchange, where mainly upcoming tech companies can enlist on the exchange, and be a traded security. I have a couple of specifics about the exchange that will set it apart from the other main exchanges, but I won't get into that now."
That's the kind of hustle that either lands you in the principal's office or on Forbes' billionaire list. Coplan ended up on the latter, but it took a while.
The Long Road From Intern To Founder
Two years after that SEC email, Coplan scored an internship at internet startup Genius through sheer persistence. He literally showed up uninvited at the company's office after his emails went unanswered. People there remembered his "wild curls" and "encyclopedic knowledge of billionaire tech entrepreneurs." Say what you will about the approach, but it worked.
Coplan then enrolled at New York University to study computer science, but dropped out in 2017 to chase cryptocurrency projects. Here's where the story gets less glamorous: those projects failed. All of them.
It wasn't until 2020 that Coplan founded Polymarket, the blockchain-based prediction market platform that would eventually make his name. And even then, success didn't come immediately. The platform gained real traction in 2024 when its U.S. presidential election market attracted billions in trading volume and correctly predicted the outcome, outperforming traditional polling methods.
From Controversy To Validation
The momentum caught the attention of serious institutional money. In October, Intercontinental Exchange (ICE), the parent company of the New York Stock Exchange, announced a $2 billion investment in Polymarket. The deal valued the platform at $9 billion post-money and pushed Coplan's net worth to $1 billion, according to Forbes. At 27, he briefly became the world's youngest self-made billionaire.
But Polymarket's path hasn't been smooth. In 2022, the U.S. Commodities Futures Trading Commission hit the platform with allegations that it was operating an "illegal unregistered or non-designated facility." Polymarket settled for $1.4 million and blocked U.S. users from accessing the platform.
The regulatory troubles continued in 2024 when both the Department of Justice and CFTC launched investigations into whether Polymarket was still allowing U.S. users despite the ban. Those probes closed in July, helped along by the pro-cryptocurrency stance of the incoming Trump administration.
Last week, Polymarket officially reopened to U.S. users. The company pulled this off by acquiring a CFTC-licensed exchange earlier in the year, giving it the regulatory approval it needed to operate legally in American markets.
So yeah, Coplan's right. What looks like overnight success usually has a much longer backstory. In his case, it involved a decade-plus journey from cold-emailing regulators as a high schooler to running a multi-billion dollar platform. The overnight part just happened to be very, very well documented on the blockchain.
