NEW YORK: Fun, the payments infrastructure company powering some of the largest internet-native capital markets, including Polymarket, today announced a $72 million Series A funding round. Co-led by Multicoin Capital and SignalFire, the funding comes as demand surges for faster, more reliable global money movement across fintech and digital markets.

Founded in 2022, Fun has operated in stealth, building its proprietary technology to become the payments backbone for platforms operating at a global scale. Today, Fun powers deposits, withdrawals, and settlement flows for platforms including Polymarket, Lighter, and Aave, where payment performance directly impacts user behavior and platform growth. Fun processes over $18 billion in transaction volume per year, supporting millions of users across more than 100 countries.

“Fun is focused on a simple but foundational problem: removing the technological barrier of value exchange,” said Founder and CEO Alex Fine. “The infrastructure for moving money has not kept up with how the world actually works. We are building a system where value moves instantly, globally, and without friction”.

Fun's deliberately small, engineering-led team has built a unified payments layer that delivers the highest-converting deposit flow for global money applications.

"Polymarket runs at a scale that breaks most payments infrastructure,” said Josh Stevens, VP of Engineering at Polymarket. “We've evaluated every major payments company, and Fun is in a different category. They operate like an extension of our team, building around real user behavior and catching edge cases others miss. They are meticulous about every detail. At our size, every percentage point of conversion is millions of dollars and millions of users, and every reliability failure becomes a public conversation. Fun has built the highest-converting, most reliable deposit flow we've ever had."

The raise will support continued investment in engineering, expansion into Asia-Pacific with a new Singapore office, and selective acquisitions to deepen the company’s infrastructure stack.

“Financial markets have driven global prosperity for decades, but the systems behind them have not kept pace,” continued Fine. “They were built for a slower, more fragmented world. Different rails, different currencies, different systems that do not interoperate. That fragmentation shows up as friction, which is the enemy of conversion. Fun has solved that problem.”

As demand accelerates across fintech, trading platforms, and digital asset applications, Fun is realizing its vision as the payments layer behind a new generation of financial services, handling the complexity of moving money so platforms can focus on building their core products.
