SIS

What we found

SIS has been supplying betting content since 1986 — a decade before the first online bookmaker existed. The company built its business feeding live racing pictures into British betting shops, and that origin explains what it is today: not a platform vendor, but the source of the events your customers bet on.

Then there is the number almost nobody else in this directory publishes. SIS states margins of 16 to 20 per cent on its racing betting content. Pricing is the field most often missing from these cards, and here it is quantified — which means an operator can model the economics before the first call rather than after the third.

What SIS sells is a continuous stream of things to bet on: horse and greyhound racing, virtual events, and the live pictures that go with them, delivered around the clock so a betting shop or an online sportsbook is never showing an empty screen at three in the morning. The Racing WA agreement signed in November 2025 added Western Australian racing to that supply, extending the content day further into hours when European racing has stopped.

Milton Keynes is home, with offices in London and MediaCityUK. The United Kingdom and Ireland are the core markets, with international distribution beyond them.

One practical caveat sits in the support hours. SIS lists office-hours cover — weekdays to five, or daily to six — rather than the round-the-clock desk most suppliers here advertise. For a content feed that runs through the night, ask what happens at two in the morning when a stream drops mid-race, and get the escalation path in writing before you sign.
