Imagine a friend borrows 95 cents from you and promises to give back a dollar in a couple of days. The friend is reliable and always pays back. You wait a little — and get slightly more than you gave.

High-probability events work much the same way. Polymarket has events whose outcome is almost clear, and the ticket for that outcome costs, say, 95¢. When the event resolves, the ticket becomes $1. You buy such tickets, wait a few days and collect the difference.

In short

  • The strategy buys outcomes that are almost certain to happen and holds them until the event resolves.
  • The return per trade is small, but the trades are calm and clear.
  • What matters is choosing events by topic, timing and price — and that's the bot's job.

Where the return comes from

Why does a nearly certain outcome cost 95¢ and not a dollar? Because until the event resolves, the money in it is "locked". Some people don't want to wait a week and sell the ticket a bit cheaper to free up their money now. The market pays for waiting — and that payment goes to whoever is ready to wait.

Example

The event resolves in 3 days. The "Yes" outcome is almost clear, the ticket costs 96¢. You buy 50 tickets for $48. After 3 days the event resolves → 50 × $1 = $50. The money is free again and can go into the next event.

How to choose events

  • Topic. It's better to take events where the answer depends on clear facts: politics, economy, technology, world news.
  • Timing. The sooner the event resolves, the sooner the money comes back and goes into the next trade.
  • Price. A ticket that's too cheap means the market still has doubts. One that's too expensive leaves almost nothing to earn.
  • Rules. Read exactly how the event resolves and where the answer comes from.

Tip

Don't put all your money into one event. Many small trades on different events are calmer than one big one.

Why doing it by hand is inconvenient

There are hundreds of such events on Polymarket, and new ones appear every day. By hand you'd have to scan markets daily, read the rules, calculate the return per day of waiting and track when money frees up. It's boring, long work — exactly right for a program.

How the Potabo bot does it

Once a day the bot scans the venue and picks suitable outcomes by your topics, timing and price. Then it ranks them by return per day of waiting and enters with small amounts. When an event resolves and money frees up, the bot takes the next one. And so on, until you stop it.

In Potabo

  • Topics of your choice: politics, world, economy and technology by default — add or remove any.
  • Minimum trade — $5, and you set the bot budget.
  • Every trade is visible in the dashboard: what was bought, at what price and when it resolves.

Frequently asked questions

How long does one trade last?

Usually 1 to 6 days, until the event resolves.

Why is the return per trade small?

Because nearly certain outcomes are never cheap: the higher the chance, the higher the price and the smaller the gap to a dollar.

Can I sell the ticket before the event resolves?

Yes, you can sell at any time while the market is open. But usually it's held to the end: that's how the strategy is designed.

What if the event resolves differently than expected?

It happens — "nearly resolved" isn't "resolved" yet. That's why the strategy splits the budget into many small trades across different events.

Can I try it without money?

Yes. On demo the bot picks and buys the same events, only with virtual money.
