How do I make a trade on SI Predict?

Trading on SI Predict is straightforward and user-friendly. Here’s how it typically works, step by step:

  • Select a Market: First, choose an event market you want to participate in. For example, let’s say the market is “Will Player A be the league MVP this season?”.
  • Choose Your Outcome (Yes or No): Inside the market, you’ll see two options corresponding to the possible outcomes (Yes and No). Each option shows a current price. Let’s say “Yes” is priced at $0.30 (30¢) and “No” at $0.70 (70¢). If you believe Player A will indeed win MVP, you would look to buy Yes shares.
  • Enter Your Trade Amount: Decide how much money (USDC) you want to put behind your prediction. Suppose you want to spend 100 USDC on your trade. If “Yes” costs $0.30 per share, 100 USDC would buy you roughly 333 shares of “Yes” (minus any small fees). The interface will calculate and show the number of shares you’ll get and the potential payout if you’re correct.
  • Review the Trade: The platform will usually display an order summary. For instance: “Buying 333 shares of ‘Yes’ at $0.30 for a total of 100 USDC. Max payout if ‘Yes’ wins: 333 USDC.” You’ll also see any fee (if applicable) and the price impact if your trade is large (large orders can move the price).
  • Execute the Trade: Confirm the transaction. If you have sufficient USDC in your wallet, the trade will be executed immediately (market order). In an AMM-style system, your trade is instant; in an order book system, it might wait for a matching order, but SI Predict abstracts most complexity so typically it feels instantaneous.
  • See Your Position: After trading, your position will appear in your portfolio or the market page, showing how many shares of each outcome you hold. You’ll also see an updated average buy price for your shares and unrealized profit/loss based on the current market price. Note that exact positions may vary slightly from what is expected based on slippage. Slippage refers to the difference between the expected price of a trade and the price at which the trade is executed due to market factors.
  • Managing the Trade: You can hold the shares until the market resolves (if you’re confident in the outcome), or you can sell them at any time before resolution to either take profit or cut losses. Using the above example, if Player A starts performing well and the price of “Yes” rises to $0.60 later in the season, you might choose to sell some or all of your 333 shares at the higher price. You’d get 0.60 * 333 ≈ 199.8 USDC, turning a profit (since you originally paid 100 USDC). Conversely, if he performs poorly and “Yes” drops to $0.15, you could sell to salvage some funds (0.15 * 333 ≈ 50 USDC), or hold and hope for a turnaround.
  • Await Outcome: If you hold until resolution, the outcome will be decided (Yes or No). If you held shares in the correct outcome, you’ll receive 1 USDC per share. If you held the wrong side, those shares end up worthless and you lose the amount you spent on them. The platform will handle the payout automatically, crediting your wallet with any winnings.

That’s the trading process in a nutshell: pick a side, name your stake, and confirm. The key is that you can always trade in and out of positions – you’re never locked in until the end unless you choose to be.
