Fun Secures $72 Million to Power Global Digital Asset Movement

Fun raised $72 million in a Series A funding round to expand its payments infrastructure that powers Polymarket and other internet-native capital markets.

The company was founded in 2022, has operated in stealth, and now processes over $18 billion in transaction volume per year, delivering a 99.999% success rate and supporting millions of users across 100 countries, it said in a Friday (May 1) press release.

With the new capital, Fun plans to continue investing in engineering, expand into the Asia-Pacific region with a new office in Singapore, and make acquisitions to deepen its infrastructure stack, according to the release.

Fun Founder and CEO Alex Fine said in the release that the company is building a system for use behind financial markets that moves money instantly, globally and without friction.

“Financial markets have driven global prosperity for decades, but the systems behind them have not kept pace,” Fine said.

Polymarket Vice President of Engineering Josh Stevens said in the release that Fun builds around real user behavior, catches edge cases that others miss, and is 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,” Stevens said. “Fun has built the highest-converting, most reliable deposit flow we’ve ever had.”

It was reported April 16 that Polymarket and rival prediction market platform Kalshi had seen combined year-to-date volumes of $60 billion. Overall, prediction market volumes are on track to come to around $240 billion this year and hit $1 trillion by 2030.

Fun’s Series A round was co-led by Multicoin Capital and SignalFire, according to the company’s Friday press release release.

SignalFire said in a Friday post on LinkedIn that most payment infrastructure can’t keep up with modern capital and that Fun is rebuilding the system from the ground up rather than trying to put a better user interface on top of old rails.

“At the scale that global applications operate, payment performance isn’t just a boring back-office thing; it makes or breaks user retention,” SignalFire said in its post. “Fun engineered a custom, highly technical orchestration layer to handle that exact challenge.”
