OUTLIER Sports Trading Engine

A Betfair trading engine that refuses to bet real money until it has proven itself.

What we set out to build

To treat sports markets as a trading problem rather than a punting one, with the same discipline the founder applies to financial markets.

What was built

  • A live market feed with four-gate routing before any order is considered
  • An evidence-required attestation layer: the engine cannot claim an edge without the data behind it
  • A paper lock that must be explicitly removed, plus four validation gates that must all pass
  • A fork adding odds aggregation across bookmakers and prediction-market feeds

What it achieves

  • 215 tests
  • Real money is still gated, and deliberately so: the four validation gates have not all been cleared, and the engine says so rather than being quietly switched on
  • Prediction-market integration is data-only by design, because order placement is geoblocked in Australia and pretending otherwise would be a compliance problem
The hard part: The discipline was in refusing to launch. Everything is built and tested; the gate is a judgement about evidence, not a missing feature.

The stack

Python, Betfair API, The Odds API.

Common questions

How was this built?

This was built through Colabs, our sister company. A founder brought the idea and the domain knowledge, Colabs brought the team, the founder funded the build with a monthly subscription, and they hold equity in the company that resulted. We label every case study, because a studio that publishes its prices and argues the other side of its own comparisons has to be equally precise about its own portfolio.

What state is it in?

Live path wired, real money gated. We state that plainly rather than describing everything as production: several things here are deliberately gated, and the reason is usually evidence rather than a missing feature.

Can you build something like this for us?

That is the point of publishing it. The same patterns are in the catalogue at published prices, and you can scope your own version on the plain-English page without contacting us first.

Where to next

If something here is close to what you need, the same patterns are in the catalogue at published prices, or you can describe your version in plain English and get it scoped and priced without talking to anyone.

Want something like this built?

The catalogue prices the patterns behind this work. Describe your version and the engine will scope it, including an allowance for anything nobody has costed.
