What White Swan Data does
White Swan Data is a London-based private technology company operating at the intersection of betting, quantitative research, and software development. It provides institutional-grade liquidity, risk pricing, and execution infrastructure for prediction and event markets, serving exchanges, platforms, data providers, and institutional participants globally. The company's core offering, WSD Predicts, prices and absorbs event risk on demand, resolving large and complex RFQ flow efficiently across supported prediction markets, with the firm quoting more than 10 million RFQs daily across six prediction markets while maintaining 99.9% platform uptime. It is headquartered at 125 Kingsway, WC2B, London, and was founded by Bernard Marantelli.
The firm builds custom quantitative trading and pricing platforms from scratch, combining mathematics, data science, and engineering capabilities with what it claims is 20+ years of combined team experience in exchange trading. Its proprietary infrastructure is purpose-built for institutional-scale execution, enabling counterparties to trade large block sizes with consistency and pricing precision across sports markets (from horse racing to MMA) and event-driven prediction markets. Disclosed strategic partners include Kalshi, Polymarket, Betfair, Crypto.com, Pred, and Matchabook, alongside an additional logo visible on the WSD Predicts page. Technology stack is entirely custom rather than third-party, with risk pricing, RFQ execution, and liquidity provision delivered as integrated infrastructure.
White Swan Data generates revenue primarily through transaction fees earned from liquidity provision and RFQ quoting to exchanges and platforms. Its go-to-market is enterprise-focused B2B institutional sales with direct engagement via a dedicated email ([email protected]) and Calendly-based scheduling for prospective clients. Pricing is not publicly disclosed and is negotiated on a custom basis. The company appears privately held with no disclosed external investment, and operates with 101-250 employees.

White Swan Data competitors and assessment
Company assessmentEmerging players
- Keyrock: Digital asset market maker and liquidity provider focused on crypto venues. Comparable as an institutional-grade liquidity partner to crypto exchanges and DeFi protocols, mirroring White Swan Data's role with Polymarket and Crypto.com.
- Wintermute: Crypto-native algorithmic trading firm and liquidity provider for digital assets. Direct comparable as a tech-forward liquidity partner for crypto venues like Polymarket and Crypto.com where White Swan Data also operates.
Broad incumbents
- Citadel Securities: One of the largest institutional market makers globally across equities, options, and other asset classes. Represents the scaled competitor that could enter prediction-market liquidity provision at scale if the category grows.
- Susquehanna International Group: Global quantitative trading firm and long-standing institutional market maker across asset classes. Comparable as a large, capital-rich liquidity provider with proprietary pricing infrastructure, though much broader in scope than White Swan Data's prediction-market focus.
- Optiver: Global market maker specializing in derivatives and exchange-traded products. Analogous in providing committed, two-sided liquidity on exchanges with proprietary pricing — relevant precedent for institutional event-market market making.
- Akuna Capital: Quantitative trading firm specializing in options market making and liquidity provision. Comparable as a sophisticated derivatives liquidity provider using proprietary technology and quantitative pricing models.
- Hudson River Trading: Quantitative trading firm providing liquidity across global financial markets. Comparable in operating proprietary technology stacks for institutional-scale execution and pricing, with similar quantitative pedigree.
- Jump Trading: High-frequency and quantitative market making firm operating across multiple venues and asset classes. Relevant as a scaled liquidity provider that could credibly enter the prediction/event market space alongside White Swan Data.
- DRW Trading: Diversified quantitative trading firm with subsidiaries in crypto and event-derivative-adjacent markets. Comparable as a multi-asset liquidity provider with a track record of trading in newly-formed asset categories including crypto.
- Flow Traders: Liquidity provider focused on exchange-traded products and derivatives globally. Comparable as a committed institutional liquidity partner to trading venues, with similar revenue model of earning spreads/fees from flow provision.
