About Poly Portfolio.
Prediction markets tell you what the world actually thinks will happen. We make that something you can invest in — by theme, in a single click.
What we do
Poly Portfolio turns scattered event contracts into curated portfolios. Instead of hunting down individual markets and placing bet after bet, you buy one basket built around a theme — the 2028 Democratic field, the Fed's rate path, AI regulation, climate policy — and hold a coherent position across every market inside it.
Think of it as index investing for prediction markets. You bring the view; we handle the assembly.
The problem we set out to solve
Prediction markets are some of the most honest signals we have about the future. When real money is on the line, prices get sharper than polls or pundits. But actually using them is a grind: dozens of related markets, each bought one at a time, with no clean way to express a single idea like "the incumbents are in trouble" or "rate cuts are coming." Building that position by hand — and rebalancing it as the world moves — is tedious enough that most people give up before they start.
We built Poly Portfolio so you can act on a thesis, not assemble it manually.
How it works

A single action gives you a position across all the markets in that portfolio.
Track it like a portfolio, not a pile of bets
Composition, performance, and holdings live in one view.
What makes us different
You stay in control
Non-custodial by design — your account, your funds, your trades. We're the lens, not the vault.
Radical transparency
Every holding, price, and weight is visible before you buy. No black boxes, no mystery baskets.
Built for a thesis, not a gamble
Portfolios are organized around ideas about the world, so you can back a view instead of chasing single outcomes.
Education first
We explain how prices become probabilities and how to read your edge before you risk a cent.
Why we're building this
We think event markets are quietly becoming a real asset class — a way to put money behind your read on the world, the way an index fund lets you back your read on the economy. The signal is already there. The tools to invest in it like a portfolio haven't caught up. That's the gap we're closing.
Event markets carry real risk, and prices can move against you. Everything we publish is educational and is not financial advice.
