Frequently asked questions.

Poly Portfolio is a platform that lets you buy curated portfolios of prediction market contracts in a single click, using your own connected Polymarket account. Instead of placing individual bets on separate event markets, you purchase a themed basket — such as the 2028 Democratic field or the Fed's rate path — and hold a position across every market inside it. Poly Portfolio is non-custodial: trades execute through your own account and we never hold your funds.

A prediction market portfolio is a basket of related event contracts grouped around a single theme, bought and tracked as one position. For example, a 2028 Democratic nomination portfolio might hold YES contracts on seven candidates at an average price of around 14¢, giving you exposure to the whole field instead of a single outcome. It works like an index fund for event markets: one purchase, diversified exposure, one performance number to track.

Buying a portfolio on Poly Portfolio takes three steps: connect your Polymarket account via API, choose a themed portfolio, and confirm the purchase. The platform then places the underlying orders across every market in the basket through your own account. Each portfolio displays its full contents before you buy — every market, current price, weight, and risk level — so you know exactly what you're holding.

No. Polymarket is a prediction market exchange where individual event contracts are traded; Poly Portfolio is an independent tool built on top of it that bundles those contracts into themed portfolios. You still trade on Polymarket through your own account — Poly Portfolio organizes the markets, constructs the baskets, and executes the basket purchase for you. We are not affiliated with Polymarket.

No. Poly Portfolio is non-custodial — your funds stay in your own Polymarket account at all times. When you buy a portfolio, the trades are executed through your account via an API connection you authorize. You can revoke that API access at any time from your Polymarket settings.

A prediction market price is the market's implied probability of an event happening, expressed in cents. A contract trading at 25¢ implies roughly a 25% chance the event resolves YES; if it does, the contract pays out $1.00, a gain of 75¢ per contract. If the event resolves NO, the contract expires worthless. This is why a portfolio's average price matters: a basket averaging 14¢ per contract is a portfolio of long-shot positions where a single correct call can outweigh several losses.

A basket spreads your risk across multiple outcomes while still expressing one thesis. In a 7-candidate nomination portfolio, you don't need to pick the exact winner — you need the winner to be inside your basket. Single-market bets are binary: right or wrong. A portfolio lets you be approximately right and still profit, the same logic that makes index funds attractive versus picking individual stocks.

The risk level summarizes how volatile and binary a portfolio's outcomes are. A "High" risk portfolio typically holds low-priced contracts (long shots) on events far in the future, where prices can swing sharply on news and most positions may expire worthless. Lower-risk portfolios hold contracts closer to resolution or priced nearer to certainty, where moves are smaller. Risk level is shown on every portfolio before you buy.

The key difference is that event contracts resolve to a fixed value — $1.00 or $0 — on a known question, while stocks have open-ended value. A stock portfolio's return depends on company performance over time; an event portfolio's return depends on whether specific real-world outcomes occur. Event portfolios also have defined endpoints: when the underlying events resolve (an election, a Fed meeting), the position pays out and closes.

Yes — every Poly Portfolio basket displays its complete holdings before purchase: each market, its current price, its implied probability, the YES/NO direction, and the basket's average price. There are no hidden positions. For example, a 2028 Democratic Field portfolio might show 7 YES positions ranging from 3¢ to 25¢ with a 14.32¢ average.

Poly Portfolio does not charge any fees.

Access to Polymarket depends on your jurisdiction, and Poly Portfolio requires a funded Polymarket account, so the same regional restrictions apply. Nothing on Poly Portfolio is financial advice, and event markets carry real risk of loss.

You can start in under five minutes: create a Polymarket account if you don't have one, generate an API key, connect it to Poly Portfolio, and browse portfolios by theme. Your first purchase can be a single basket — each one shows its holdings, average price, holders, and historical performance so you can compare before committing funds.
