# Prediction market infrastructure

> Build + operate prediction markets — onchain or off.

**Sector**: [Web3](https://signals.gitdealflow.com/niche-down/web3)  
**Build cost**: Team-sized build  
**Deal velocity**: Trickle — one deal per quarter

## Why now

Polymarket exposed the demand. The infra layer is open for vertical + niche markets.

## What the signal looks like

Repos with market-creation libraries, oracle integrations, and settlement-engine frameworks.

## Public examples

*Public projects + categories only — we never name founders tracked inside the paid product.*

- Polymarket adjacency
- Kalshi
- Open-source prediction-market libraries

## What this displaces

A Twitter poll + no liquidity.

## Our build-vs-invest call

Speculative. Fund only with crypto + finance team. The moat is the liquidity + the regulatory + the oracle reliability.

## Frequently asked

### Buyer?

Market operators + media + research firms.

### Pricing?

% of volume.

### Compliance?

CFTC + state gambling laws.
