VCs Place Bets on Betting: Polymarket and Kalshi CEOs Launch '5c(c)' Fund to Back Prediction Market Degens

A new venture capital firm, 5c(c) Capital, is launching to invest specifically in companies built around prediction markets—because nothing says “serious finance” like betting on whether a celebrity will get a tattoo of a crypto mascot. The fund is backed by the CEOs of Polymarket and Kalshi, two platforms that turned political polls into crypto poker tables and somehow didn’t get shut down by the SEC… yet.

The fund aims to raise up to $35 million and back about 20 early-stage startups over two years. Its focus? Infrastructure and services like data tools, liquidity provision, and compliance systems—not the exchanges themselves, because even degens need someone to clean up after them when the market goes full “Elon tweets ‘dogecoin to the moon’ at 3 AM.” Think of it as building the plumbing for a casino where everyone’s betting on whether the next Fed chair will wear socks with sandals.

The launch comes amid rapid growth in prediction markets, marked by rising trading volumes, new users, and interest from major crypto and retail trading platforms. It has already attracted more than 20 early investors, including a Millennium Management portfolio manager and other prediction market founders—people who clearly prefer to hedge their bets on a presidential debate outcome rather than just watching C-SPAN on mute.

5c(c) Capital is named after a section of the Commodity Exchange Act that governs prediction markets. Its founders state they want to 'capitalize on the second-, third-, and fourth-order effects of what we built ourselves.' Translation: We made the casino. Now we’re selling the chips, the napkins, and the emergency PTSD therapy for people who lost their life savings on “Will Taylor Swift release a song about a blockchain dev by 2025?”

Prediction markets are shifting from a niche corner of finance into a more visible part of how people track events. Since the U.S. presidential election, trading volumes have climbed and new users have entered the space—many of whom thought they were signing up for a fantasy football app but ended up shorting the probability of the moon landing happening before 2030.

Platforms like Polymarket and Kalshi now host contracts tied to politics, economic data, and cultural events, turning public opinion into tradable signals. Polymarket's trades run on the blockchain—because if you’re going to bet on whether a politician will resign, at least make it immutable, trustless, and slightly chaotic. It’s Wall Street meets Twitter thread, with gas fees.

Many crypto-native companies, including Coinbase and Kraken, as well as Robinhood, have also entered the space in recent months. This growth has created new business opportunities beyond the platforms themselves, with startups beginning to build supporting data tools, liquidity services, and compliance systems. In other words, someone’s now making a living selling API endpoints that tell you the odds of a cat becoming president—because why not?

Polymarket declined to comment. Kalshi did not respond in time for publication. Either they’re busy hedging their own bets… or they’re still recovering from last week’s “Will Dogecoin hit $0.10 before my rent is due?” market closed.
