March 23, 2026 230 views

Shayne Coplan and Tarek Mansour, founders of competing prediction market platforms Polymarket and Kalshi respectively, have joined together as backers of a new venture capital fund focused on the sector. The fund, named 5c(c) Capital, draws its name from the specific provision in the Commodity Exchange Act that grants the CFTC regulatory authority over event contracts.

Unlikely Partnership Between Market Competitors

The collaboration marks a notable development in the prediction markets space, bringing together two executives whose platforms have competed directly for market share. Coplan's Polymarket operates on blockchain infrastructure and gained significant attention during the 2024 election cycle, while Mansour's Kalshi functions as a CFTC-regulated exchange for event contracts in traditional finance.

According to Fortune, which first reported the news, both founders will serve as limited partners in the fund. The exact size of the fund and the specific investment thesis beyond prediction markets have not been disclosed. The fund's naming choice signals a clear focus on the regulatory framework governing prediction markets and event contracts in the United States.

Implications for the Prediction Markets Sector

The establishment of 5c(c) Capital suggests growing investor confidence in prediction markets as a viable and expanding industry segment. For professionals working in blockchain, fintech, and regulatory compliance, this development indicates potential growth in opportunities within the prediction markets ecosystem.

The fund's formation comes at a time when prediction markets face ongoing regulatory scrutiny and evolving frameworks. Professionals with expertise in CFTC regulations, smart contract development, and market infrastructure may find increasing demand for their skills as the sector attracts more capital and institutional interest.

The involvement of both crypto-native and traditional finance founders in the same investment vehicle also highlights the convergence happening within prediction markets. This could create new career pathways for professionals seeking to bridge blockchain technology and regulated financial markets, particularly those with backgrounds in compliance, product development, and market operations.

As 5c(c) Capital begins deploying capital, the broader prediction markets industry may see accelerated hiring and expansion among portfolio companies.
