Markets your app can’t list today.
Today a sports market offers one kind of ticket: over or under a published number. functionSPACE is the market layer that lets that same number carry many different tickets. We ran it live through the World Cup with partners you know; here is what happened, and what we could run together next season.
- Over / under
- Range
- Precision call
- Head-to-head duel
- …any shape
Over/under is one shape of many.
Every ticket is really a payoff shape drawn over a number. Over/under is the simplest one: it pays a flat amount if the number lands on your side of the line. Change the shape and you have a genuinely different bet on exactly the same market, priced by the same engine.

Demonstrated live during the World Cup.
Three weeks of knockout football, traded on fantasy points rather than results: not who wins, but how each player performs. Three partner apps ran on one shared market layer, each with its own interface and its own audience: Polysights, Trepa and Kelvon.
| Window | Round of 32 → Final |

| Stakes | Play-money · off-chain engine |
| Surfaces | Four apps on one market layer |

Read the full case study for the campaign in detail: the architecture, the partner integrations, and every figure quoted on this page.
129 markets settled, 8,800+ positions, four apps on one book. A real audience trading shapes no sportsbook lists today.
Two new trades from what’s already familiar.
The whole interface uses modes a sports trader already knows: take a line, or pick a range, and makes these dynamic choices. What comes back is a ticket no sportsbook currently lists, a payoff exactly as the user wants.

Figure 2. The ticket is a payoff shape. Move the line here or in the app; the screen and the curve are one market. Switch to in / out and the same number becomes a range bet, priced by the same engine.
Advanced modes, made easily.
Trepa built a mode neither other app offered: a precision call, where a trader names the number they expect and says how confident they are. Underneath, that buys a triangle payoff peaked on their call. It runs on the same markets as all other positions.

Figure 3. A call plus a confidence band is a triangle payoff. Tighter band, sharper triangle, richer payout. And precision paid: point estimates returned −44.9% against −76.8% for range bets, about 32 points better per unit staked.
Numerical flexibility, user simplicity.
You choose what the market measures. Settle it on the difference between two players’ fantasy points and a head-to-head becomes one ordinary number line, so “who has the better game” is simply a ticket on it. Choose the unit well and a complicated proposition turns into a one-tap decision.
Messi has the better game: more fantasy points tonight.

Different venues, different games.
Identical markets underneath, three completely different trading signatures on top. Each venue’s interface drew its own kind of trader, and all of that flow met in one book.
Users took to it.
Across 129 settled markets and more than 8,800 positions, what traders valued was the part we most wanted to test: each shape made plain sense to them. Their own words, from the post-campaign survey.
“Easy to understand.”
The over/under is the door everyone walks in through, and nothing about it had to be taught. Of those surveyed after the Final, 16 of 17 said they would trade these markets for real money.

“Range is quite specific and better reflects how we view the odds.”
Given a shape with more room in it, traders used the room. 41% of propSPACE range picks were two buckets or narrower, a deliberately tight call rather than a safe wide one.

“Easier to predict.”
A head-to-head asks who beats whom rather than how much, and that turned out to be the easier question. It drew 72% of Trepa’s final-round traders.

Build unique trades for your users
Four shapes, four different things they unlock. These are the same four categories the chart at the top of this page is built on, so whatever you pick here is something you have already seen priced.
- You ship
- The over/under you already post, priced as a payoff instead of a fixed quote.
- It gets you
- The entry every user already recognises, and the door to the other three.
- You ship
- A band between two numbers, cut into as many buckets as the market deserves.
- It gets you
- A specific read becomes a specific ticket, at odds one line cannot express.
- You ship
- A position that pays in proportion, worth more the further the number runs their way.
- It gets you
- Conviction without a cliff, so a result never turns on one point either side.
- You ship
- Any payoff you can draw, over any stat you already publish.
- It gets you
- A listing surface that is not a fixed menu, so anything worth a price can have one.
Let’s run one of these together.
