Catenaa, Friday, March 27, 2026-Executives from leading prediction market platforms and major venture investors have launched a $35 million fund to back startups building infrastructure for the fast-growing sector, according to details shared this week.
The fund, called 5c(c) Capital, is supported by Tarek Mansour of Kalshi and Shayne Coplan of Polymarket, alongside investor Marc Andreessen and others. The fund plans to invest in about 20 companies over two years, focusing on trading infrastructure, data tools and compliance systems.
The initiative comes as prediction markets record rapid growth. Combined trading volumes reached $127.5 billion by early 2026, with Kalshi and Polymarket accounting for most activity. The expansion has drawn attention from investors seeking exposure to alternative data markets tied to elections, economic events and global trends.
Fund managers say the goal is to build the underlying systems needed to support long-term adoption. Planned investments include market-making technology, pricing indices, developer tools and regulatory compliance software. These areas are seen as critical for scaling platforms while meeting oversight requirements.
Regulatory developments in the United States have added momentum. The Commodity Futures Trading Commission recently outlined expectations for event-based contracts, signaling federal oversight of prediction markets. Officials have emphasized the need for safeguards around market manipulation and retail participation.
At the same time, legal uncertainty remains. Several states have challenged federal authority over prediction markets, raising questions about jurisdiction. Proposed legislation in Congress could also limit certain types of contracts, particularly those linked to sports events.
Despite competition between platforms, collaboration on the fund reflects a shared interest in expanding the broader ecosystem. Kalshi operates as a regulated exchange within the US, while Polymarket serves global users through crypto-based systems. Industry participants say both models require stronger infrastructure to support growth.
Investor interest has surged alongside rising valuations. Kalshi recently secured funding at a reported $22 billion valuation, while Polymarket is exploring a potential raise near $20 billion. These figures highlight growing confidence in prediction markets as a distinct financial sector.
Startups in the space are also gaining traction. New entrants are building tools for data aggregation, liquidity provision and application development. Some platforms are experimenting with integrating prediction markets into social media and decentralized finance systems.
Backers of the fund argue that prediction markets can improve forecasting by aggregating crowd insights more efficiently than traditional polling methods. Increased liquidity and better tooling are expected to enhance accuracy and participation over time.
However, risks remain. Regulatory actions could restrict market access or limit product offerings. Liquidity fragmentation and concerns about insider activity also pose challenges for operators seeking mainstream adoption.
The launch of 5c(c) Capital signals a shift toward infrastructure investment as the sector matures. Rather than focusing solely on consumer platforms, investors are targeting the underlying systems that enable trading, compliance and scalability.
Market participants expect continued growth through 2026, particularly around major political and economic events. Analysts say the success of the fund will depend on how quickly startups can address regulatory demands while improving user experience and market efficiency.
