Company profile
researched Aug 2026BetDEX (BetDEX Labs, Inc.) operates a decentralised sports betting exchange built on the public blockchain Solana. The platform is designed around the Monaco Protocol, which the company describes as connecting bettors worldwide in a single decentralised sports betting community. BetDEX markets itself on non-custodial settlement, low fees, competitive odds, and the absence of account restrictions or premium charges for successful bettors.
Wagers on the exchange are settled via smart contracts, so the platform does not hold customer funds, which the company says reduces settlement delay and eliminates counterparty risk. At launch the protocol was intended to be open-source and fully decentralised so third parties could build their own applications on top of it, and the company planned to accept wagers in Tether (USDT), Solana (SOL) and Samoyed coin (SAMO).
The company was founded in 2021 by Varun Sudhakar (CEO and co-founder), Nigel Eccles (chairman and co-founder) and Stuart Tonner (CTO and co-founder), all formerly of FanDuel. By July 2023 BetDEX described itself as a UK-headquartered company with a local presence in Ireland, holding gambling licences from the Isle of Man and Ireland.
Founding story
BetDEX was founded in 2021 by three former FanDuel executives: Nigel Eccles, who co-founded FanDuel in 2009 and took it to become Scotland's first $1bn-valued startup before its 2018 acquisition by Flutter; Varun Sudhakar, who began his career in investment banking in Silicon Valley and worked with Eccles in senior strategy and corporate development roles at FanDuel between 2015 and 2018 before executive roles at other startups in New York; and Stuart Tonner, FanDuel's first engineering hire, who spent more than eight years building and scaling its platform. Eccles took the role of non-executive chairman, Sudhakar CEO and Tonner CTO, with the trio stating they intended to build the business from a base in Scotland.
Business model
BetDEX runs a peer-to-peer betting exchange rather than a traditional sportsbook: bettors trade positions against one another on markets settled by smart contracts on Solana, with the operator not holding customer funds. The underlying protocol is intended to be open-source and decentralised so third parties can build applications on top of it.
Sources describe BetDEX as competing on low fees against incumbent exchanges that charge high fees and impose premium charges; no specific fee levels or revenue figures are disclosed in the available sources.
Traction
The exchange recorded over $1.5m in matched wagers in the six months to July 2023, growth the company attributed to expanded sport coverage across tennis, cricket, UFC and esports and the addition of in-play markets. Planned market launches at that time included the Rugby World Cup in France, the ICC Men's Cricket World Cup in India and cycling.
Latest developments
The most recent developments in the sources are the Irish trading licence and in-play betting launch in July 2023, plus expanded sport coverage; a July 2024 industry newsletter identified BetDEX as a blockchain-based exchange startup of note.

Market position
BetDEX positions itself as the first betting exchange built on decentralised technology, competing against established sports betting incumbents and exchanges on price, product and the absence of restrictions on winning bettors. Trade coverage has grouped it with blockchain-based exchanges and referenced prediction market operator Polymarket in the same context. Sources cite the global sports betting market as valued at $203bn in 2020 and forecast to reach $350bn by 2024.
Non-custodial settlement via smart contracts, low fees, and an explicit policy of not restricting or surcharging successful bettors distinguish BetDEX from incumbent sportsbooks and exchanges, alongside a founding team drawn from FanDuel's earliest employees and executives.
Technology
The exchange is built on the Solana public blockchain and leverages the Monaco Protocol. Bets are settled immediately through smart contracts on a non-custodial basis, which the company says removes counterparty risk and enables fast, low-cost trades. The protocol was described at launch as open-source and extensible by third-party developers, accepting USDT, SOL and SAMO.
Go-to-market
BetDEX pursues regulated market entry through gambling licences (Isle of Man in October 2022, Ireland in July 2023) and expands its addressable audience by adding sports and market types, including in-play betting and side markets. It also publishes content such as previews and analysis via a newsletter to attract bettors.
Retail sports bettors, including high-volume and consistently winning bettors who face account restrictions or premium charges at conventional operators, in licensed markets such as Ireland and the Isle of Man.
Geography
Described in 2023 as UK-headquartered with a local presence in Ireland; the founding team stated it would scale the business from a base in Scotland. Licensed in the Isle of Man and Ireland, with the Irish licence giving access to the EU market.
History
The company was founded in 2021 and announced a $21m seed round in November 2021, describing itself as building the world's first decentralised sports betting protocol, with launch planned for the first half of 2022. It received an online gambling licence from the Isle of Man in October 2022 and a licence to trade in Ireland announced in July 2023, the latter coinciding with the introduction of in-play betting for cricket and tennis on 3 July 2023 and expanded coverage of tennis, cricket, UFC and esports.
Risks & controversies
The seed round was co-led by FTX, whose CEO Sam Bankman-Fried was quoted supporting the investment; the sources do not discuss any consequences of that relationship. The business is dependent on obtaining gambling licences in each jurisdiction and on crypto infrastructure, and no sources address regulatory or financial outcomes after mid-2024.
