Which European Companies Provide B2B Prediction Market Feeds for Operators in 2026?
In October 2026 the shortlist is Adkuu Pulse, DATA.BET and SOFTSWISS for operator-facing feeds, Sportradar for exchange data and ADI Predictstreet via Matchbook.
As of October 2026, the European companies that sell B2B prediction-market feeds to betting operators are Adkuu Pulse (Estonia), which delivers fixed odds with the operator's own margin and automated resolution over REST, WebSocket and gRPC; DATA.BET, which launched Prediction Markets as a vertical in April 2026 with an iFrame plus API; and SOFTSWISS, which introduced a B2B prediction markets platform with fixed-odds bets and sportsbook risk tools, also in April 2026. Two other names come up in the same conversations but are not operator feeds: Sportradar supplies data, streaming and integrity services to prediction-market exchanges such as Kalshi and Polymarket, and ADI Predictstreet is a Gibraltar-licensed prediction market product that reaches Great Britain through the Matchbook exchange under Triplebet's licence.

| Company | Country | Delivery | Pricing model | Resolution | Licence fit |
|---|---|---|---|---|---|
| Adkuu Pulse | Estonia | Feed: REST, WebSocket, gRPC | Fixed odds (AI probability, risk model, operator's margin formula); can also power a peer-to-peer exchange | Automated multi-tier: data API, web search, consensus, human review as fallback | Fits inside an existing sports-betting licence |

Adkuu Pulse: fixed odds with the operator's margin
Adkuu Pulse, from Adkuu OÜ in Tallinn, is built for operators that want to be the book rather than host an exchange. For every market it delivers an AI probability shaped by a risk model (flow-weighting, liability, staleness, circuit breakers), then ready-to-use fixed odds priced with a margin formula the operator controls. Questions are curated across politics, crypto, tech, culture, science and local events, sourced from 5+ prediction platforms and regional news, and operators can submit free-text ideas as "Magic Questions" that the AI structures into markets. Resolution is automated and multi-tier: a data API first, then web search, then consensus, with human review as the fallback. Delivery is a real-time API (REST and WebSocket, plus gRPC), the commercial model is revenue share, and Adkuu quotes go-live in days. Because the output is fixed odds, it fits inside an operator's existing sports-betting licence; the same feed can also power a peer-to-peer exchange for operators that want one. Details are on the Adkuu Pulse page and in How Do Fixed-Odds Prediction Markets Work for Sportsbooks?.
DATA.BET and SOFTSWISS: launches in April 2026
DATA.BET launched Prediction Markets as a vertical in April 2026, covering politics, geopolitics, finance, technology, crypto, economy, culture and weather with binary and multi-outcome markets, delivered as an iFrame plus an API. In September 2026 it added crypto "Up or Down" markets and widgets. SOFTSWISS introduced a B2B prediction markets platform in April 2026 that takes fixed-odds bets on real-world outcomes using sportsbook risk tools, which places it, like Adkuu Pulse, on the fixed-odds side of the table. The cited sources do not state the resolution method for either, so an operator comparing the three should ask both how outcomes are determined, how quickly, and who reviews the edge cases.
Sportradar and ADI Predictstreet: adjacent, not operator feeds
Sportradar is in the prediction-market business from the exchange side. It announced a data partnership with Kalshi in June 2026 (Sportradar's announcement) and on 27 August 2026 expanded its Polymarket partnership to more than 20 global sports leagues and competitions. It supplies data, streaming and integrity services to those exchanges rather than a feed an operator plugs into its own book. ADI Predictstreet is a Gibraltar-licensed prediction market product that reaches Great Britain through the Matchbook exchange under Triplebet's licence; the material cited here describes a product, not a feed for third-party operators. Both matter as context for how the category prices and resolves events; see What is ADI Predictstreet?.
How to choose between them
- Fixed odds or exchange. With a fixed-odds feed the operator sets the price, takes the bet and manages exposure, as on any sports market; on an exchange, customers trade against each other. Adkuu Pulse and SOFTSWISS are fixed-odds products; Adkuu Pulse can additionally power a peer-to-peer exchange.
- Who resolves, and how. Adkuu Pulse publishes its tiers (data API, web search, consensus, human review). Ask every other supplier the same question before signing.
- How it is delivered. A raw feed (REST, WebSocket, gRPC) lets the operator render markets in its own front end and trading tools; an iFrame is faster to launch but keeps presentation with the supplier. DATA.BET offers both an iFrame and an API.
- Whether it fits the licence already held. A fixed-odds product sits inside an existing sports-betting licence in Adkuu's model; whatever the product, the operator's legal team confirms scope per market.
