// The Problem

Prediction markets have two dirty secrets nobody talks about.

Problem 01

Long-tail markets die from liquidity starvation

Orderbooks need market makers. Market makers need volume. Volume needs liquidity. It's a chicken-and-egg death spiral for any market that isn't "Will Trump win?"

90% of interesting questions → never get created
Problem 02

The platform is your counterparty

When a new market launches, someone seeds it. That someone holds positions. This creates misaligned incentives—the platform profits when you lose.

"Is the house betting against me?" → yes, probably
// The Solution

Pari-mutuel pools solve both problems.

The crowd IS the market. First dollar and last dollar are treated equally. We take a flat fee, never a directional bet.

No market maker required

The crowd provides all liquidity

No platform position

We win when markets resolve, not when you lose

True price discovery

Odds emerge from where money flows

Cold-start friendly

$100 pool works the same as $1M pool

"Orderbooks are for traders. Pools are for believers."

— Different users, different mechanics, same truth-seeking outcome.
