Markets are the questions a strategy can use. Polymarket is the supported prediction market venue. Separately, the Stocks category offers tokenized stocks on Base, which are not prediction markets and behave differently (see below). A market action attempts to buy a selected side of a market when you run the strategy; execution and fills are not guaranteed.

​
Use the Market tab

Open Market in the left panel. Market tab with filters and search shown Use the filters to browse:
  • Trending for active markets.
  • Recurring for markets that repeat.
  • Topic categories such as Politics, Sports, Crypto, Finance, Tech, and Weather.
  • Search when you know what you want.

​
Read a market card

A market card with YES and NO outcome buttons shown A market card can show:
  • The market question.
  • One or more outcomes.
  • YES and NO buttons.
  • A displayed price for each side.
  • Volume information.

​
Choose an outcome and side

Some market cards contain several named outcomes. For example, a card may list several teams or people. In that case, make two choices:
  1. Select the named outcome you mean.
  2. Select YES or NO for that outcome.
YES means you choose the side for that named outcome happening. NO means you choose the side for that named outcome not happening. Read the market question and its resolution details before choosing either side.

​
Grouped events and NegRisk markets

Some events group mutually exclusive named outcomes in one card. You may see this called a NegRisk market. It is a convenient way to compare related outcomes, such as several teams, candidates, or award nominees. For example, if you select Team A, YES means Team A wins. NO means Team A does not win; it does not mean Team B wins unless you select Team B separately. Market card where a named outcome is selected before choosing YES or NO Read the event’s resolution details before you add a grouped outcome. A group can contain similar-looking choices with very different meanings.

​
Search for a market

Use the search box to narrow the list. Search by topic, team, asset, person, or event. If you cannot find the right market, do not use a similar-looking one unless you understand how it resolves.

​
Tokenized stocks

The Stocks category in the Market tab lists tokenized stocks on Base: real equities such as Tesla, NVIDIA, and Apple wrapped as tokens (TSLAc, NVDAc, AAPLc). They are not prediction markets, and they behave differently in a strategy:
  • A stock has no YES or NO side. You either hold it or you do not, so a stock action simply buys it.
  • Its price is in dollars per share, not cents or a probability. A price condition on a stock uses a dollar threshold, for example “if TSLA crosses above $400”.
  • It is bought and sold as a token swap on Base rather than as a Polymarket order, so the price you pay is the pool’s price, which sits slightly above the reference share price. The card shows both.
  • A stock never resolves. A resolution condition cannot watch it, and a stock you still hold when the strategy finishes is sold at that point.
  • Tokenized stocks are not offered in every region. If they are unavailable where you are, a strategy that buys one cannot be run live.
Each stock card shows the live pool price and a price history you can switch between one day, one week, one month, and all time. There is no side to pick: click the card to add a Buy action for that stock, or drag it onto the canvas. A card with no price cannot be added until a price is available. The strategy assistant understands stocks too: “buy TSLA if it crosses 400andsellat400 and sell at 450” builds a complete stock strategy.

​
Add a market action to the canvas

For a prediction market, selecting YES or NO prepares the card; a tokenized stock card has no side and is added directly. Click the card to add the selected market action, or drag the card to choose a position on the canvas. When the card appears on the canvas, verify the market, named outcome, selected side, and allocation. The action defaults to 100% when it is the only action in its decision.

​
Before you add a market

  • Make sure the market question matches your idea.
  • Check how and when the market closes or resolves.
  • Confirm the displayed side is the one you intend to buy.
  • Do not substitute a similar-looking market if you do not understand its resolution.
