The Polymarket-Kalshi Rivalry Just Paused for a $35M Infrastructure Play

The financial media loves the ongoing feud between Polymarket CEO Shayne Coplan and Kalshi CEO Tarek Mansour. They are fighting a brutal, zero-sum war over user acquisition, regulatory approval, and trading volume.

But if you sit on a trading desk, you don’t read Twitter beefs; you track wire transfers. And this week, regulatory filings revealed a massive anomaly: both of these rival CEOs quietly backed the exact same venture capital fund.

The vehicle is 5c(c) Capital—a new $35 million fund named after the Commodity Exchange Act section that governs event contracts. Driven by early Kalshi alumni and backed by heavyweights including Marc Andreessen and a Millennium Management portfolio manager, this fund represents a massive shift in how smart money views event-driven trading.

When two founders who despise each other financially align on a single entity, it is not a peace treaty. It is a mathematical realization that their sector’s infrastructure is breaking. Here is our desk’s read on why this fund exists, and what it means for the derivatives market.

They Aren’t Building Exchanges. They Are Building Plumbing.

Kaishi polymarket

Prediction markets have officially transitioned from niche crypto experiments into multi-billion-dollar macro instruments. Kalshi and Polymarket are both pushing valuations near or above the $20 billion mark. Post-election trading volume has exploded, bringing retail giants like Robinhood and Kraken into the fray.

But there is a severe bottleneck: the backend plumbing.

5c(c) Capital is not raising $35 million to build a third prediction market. They are building the picks and shovels. The fund plans to deploy capital into roughly 20 early-stage startups focused entirely on secondary infrastructure. This means:

  • Specialized Market Makers: Traditional crypto market makers don’t fully understand how to price binary event contracts. 5c(c) is funding algorithms built specifically for this liquidity.
  • Decentralized Oracles & Data Layers: Secure systems that can resolve highly complex geopolitical or economic bets without relying on easily manipulated, centralized news sources.
  • Compliance Engines: Tooling required to navigate the aggressive state and federal regulatory landscape.

Coplan and Mansour invested their personal capital into 5c(c) because they desperately need these secondary companies to exist. Without independent market makers and robust liquidity engines, their multi-billion-dollar exchanges will choke on their own institutional order flow. They are funding the infrastructure for their own gold rush.

Attention as a Liquid Asset Class

This move confirms a thesis we have been trading on for months: Attention is now a liquid asset class.

In traditional finance, you trade the reaction to an event. If the Fed cuts rates, you buy equities. Prediction markets allow you to trade the probability of the event itself. By funding the infrastructure layer, Wall Street and Silicon Valley are signaling that event-based trading is not a temporary fad—it is becoming a permanent derivative layer that sits parallel to options and perpetual futures.

The Tapbit Execution Plan

For the active crypto derivatives trader, prediction markets should no longer be viewed as a distraction. They are your ultimate tail-risk hedging tool.

If you are running heavily leveraged crypto perpetuals on the Tapbit Exchange, your portfolio is highly exposed to macro news cycles. Professional traders are increasingly using Polymarket or Kalshi contracts to hedge that exact risk. By allocating a small amount of capital to a “Yes” contract on a specific macro event, you are essentially buying cheap insurance for your core margin positions.

How to play this shift:

  1. Stop looking for the next exchange token: The alpha is no longer in the prediction platforms themselves. Watch the infrastructure plays—the oracle networks, data aggregators, and liquidity protocols that will power these markets on the backend.
  2. Separate your execution: Keep your heavy, high-frequency execution on a high-performance engine designed for crypto volatility. Use prediction markets purely as a supplementary risk-management layer.

Before the next major macroeconomic headline hits the tape, log in to your Tapbit account to audit your margin health and tighten your stop-losses. If you need an institutional-grade platform that doesn’t freeze when volatility spikes, register your free Tapbit account here.
