BroadChain, April 27 - There is a classic signal on Wall Street: when competitors start betting on the same infrastructure, the industry has entered a new phase. The prediction market is witnessing this scenario. Polymarket and Kalshi—the former being the most influential event trading platform in the crypto world, and the latter one of the few event contract exchanges in the US to receive regulatory approval—follow vastly different paths: one takes a global, on-chain, decentralized route, while the other follows a compliant, CFTC, traditional finance track. Yet, the CEOs of both companies, Shayne Coplan and Tarek Mansour, have simultaneously invested in the same fund: 5(c) Capital.
5(c) Capital is a small fund targeting approximately $35 million in fundraising, established by two former Kalshi employees, Adhi Rajaprabhakaran and Noah Zingler-Sternig. The former was a Kalshi trader, and the latter served as Kalshi's head of operations. This fund is not a traditional thematic fund but rather a capital vehicle organized by industry insiders. Its investment direction is not about betting on "the next Polymarket" or "the next Kalshi," but focuses on market makers, index design, and prediction market infrastructure—who provides liquidity? Who designs event indices? Who handles cross-platform data? Who is responsible for risk control and monitoring? Who transforms prediction markets from retail gambling into an institutional asset class?
Platforms can compete, but infrastructure can be shared. Polymarket needs depth, and so does Kalshi; Polymarket needs more credible pricing, and so does Kalshi; Polymarket needs institutional participation, and Kalshi needs it even more. 5(c) is betting on the entire prediction market ecosystem, not a single entry point.
Why are Kalshi-affiliated individuals doing this? Kalshi's path is entirely different from Polymarket's: Polymarket is a crypto-native growth machine, rapidly expanding through globalization, on-chain assets, and event narratives; Kalshi, on the other hand, has chosen the US regulatory path, dealing long-term with the CFTC, state regulations, and the boundaries of event contracts. Therefore, those from Kalshi naturally focus on: which events can be designed as contracts? Which markets are prone to manipulation? Why are market makers reluctant to join? How can traders exploit non-public information? Where will regulation ultimately tighten? Typical crypto funds see growth curves, while the Kalshi camp sees market structure.
The biggest issue with prediction markets has never been "whether people want to gamble," but rather: can this gambling behavior be packaged as a financial market and withstand regulation, liquidity, manipulation, settlement disputes, and institutional scrutiny? 5(c)'s choice to invest in infrastructure is precisely an answer to this question.
Will prediction markets be monopolized by a few giants? It's highly likely. Because only a very few markets can generate effective trading; the more concentrated the liquidity, the more credible the price; the more credible the price, the more concentrated the users; the more concentrated the users, the more willing market makers are to participate; the more market makers participate, the more concentrated the liquidity—this is a typical exchange network effect. Ultimately, the market will not be evenly distributed across 100 platforms but will be concentrated in the hands of a few exchanges, clearing houses, market makers, and data terminals.
