Top iGaming Companies 2026
Last updated 3 August 2026
A guide to the major public companies that shape online gambling, what each one does, and where they sit in the value chain. Track their live numbers on the iGT 25 index.
The online gambling industry is dominated by a relatively small number of large companies that span operating brands, platform technology, game content and data. This guide describes who they are and what they do. For live financials and market values, follow the iGT 25 index and each company's own filings rather than any figure printed here.
How to place a company in the industry
Before profiling individual names, it helps to know the layers they operate in:
- Operators run the consumer brands players bet with.
- Platform and B2B providers supply the technology, payments and back-end that operators run on.
- Game studios create the slots, table games and live-casino content.
- Data and sports-data companies supply the odds, feeds and integrity services betting depends on.
Many of the largest groups span more than one layer, which is exactly why they are large.
The companies that shape the market
The following are among the most significant publicly-traded companies in the sector, several of which are constituents of the iGT 25 index:
- Flutter Entertainment is one of the largest operators globally, with a portfolio of major brands including its leading US sportsbook business.
- DraftKings is a US-focused operator that grew with the American sports-betting market into one of its best-known brands.
- Entain is a multi-brand operator across sports betting and gaming with a broad international footprint and a large US joint venture.
- Evolution is the leading supplier of live-casino content and a major force in online table games.
- MGM Resorts and Caesars Entertainment are US casino groups whose online arms are central players in American iGaming and sports betting.
- Light & Wonder and Aristocrat Leisure are major suppliers of gaming content and technology spanning land-based and online.
Alongside these, large privately-held operators are among the biggest in the world by revenue, which is why any "top companies" view has to look beyond the listed names alone.
How to use this list
- Treat it as a map of the value chain, not a ranking, because operators and suppliers are not competing for the same revenue.
- Check current scale on the iGT 25 index and in company filings, since revenue and market value move constantly.
- Watch for companies that span layers, as owning both operation and supply is where much of the sector's pricing power sits.
For the live picture of who is largest by market value on any given day, the iGT 25 index is the place to look.
Regulation, tax and market figures move quickly, sometimes mid-year. Where this guide gives a number, treat it as a starting point and confirm the current position with the named primary source before you rely on it.
