Anyone can create a prediction market on Worm. There’s no approval process, no listing fee, and no minimum. You describe what you want to predict, and Worm’s AI helps you turn it into a well-formed, tradeable market.

​
It’s free

Creating a market on Worm costs nothing. This is a deliberate differentiator. Other platforms charge significant fees per market, which limits who can create them and what gets created. Worm is designed to be open. In return, markets you create earn you a share of all trading fees, automatically.

​
The creation flow

Market creation on Worm is conversational. You describe your idea in natural language, and the AI works with you to shape it into a valid market. The AI has access to a wide range of data sources, including X (Twitter), web search, sports data, and financial data, which it uses to:
  • Understand the event you’re describing
  • Draft resolution criteria that are objective and verifiable
  • Set an appropriate resolution deadline
  • Find an image for your market based on your description
You can edit the draft before publishing. If the AI’s rules aren’t quite right, you can refine them, within the bounds of what the platform allows.

​
What the AI can create

The AI creates markets it can also resolve. This means the event needs to have a reliable, publicly verifiable outcome that the AI can check at resolution time. Good examples:
  • Sports match results
  • Election outcomes
  • Price milestones (“Will ETH reach $5,000 by June?”)
  • Public metrics (“Will this video reach 1M views by date X?”)
  • Public announcements and decisions from verifiable sources
If the AI declines to create your market, it usually means it couldn’t find a reliable source to resolve it. Try rephrasing the event with a more specific, verifiable outcome, or a more established source to check against.

​
After publishing

Once your market is live, it appears in the feed and is discoverable by category (Politics, Sports, Crypto, Tech, Finance, WTF) and by filters like Trending and Ending soon. Worm’s AI also actively monitors live markets and posts relevant news updates as comments, giving traders on your market real-time context without leaving the page. Your market exists on Worm’s order book. The first traders to find it will place the initial bids and asks, setting the starting price. Sharing your market in relevant communities is the most effective way to attract early liquidity. You earn half of every trading fee collected on your market, paid out immediately as trades happen.
