Portfolio Manager - Prediction Markets

Moreton Capital Partners (MCP) is a CFTC regulated systematic, technology-first investment manager trading across various markets. They are seeking a senior Portfolio Manager to lead their prediction markets strategy, overseeing the investment process, building a global team, and collaborating with quant research and engineering to enhance their trading models.

Responsibilities:

• Own the prediction markets P&L. Set strategy, manage risk limits, oversee position sizing, and ensure the portfolio operates within defined drawdown and exposure parameters at all times across all traders
• Lead the full investment process: idea generation, model validation, live execution, post-trade analysis, and systematic improvement cycles
• Build and manage a team of traders and analysts. Set research priorities, review work rigorously, and develop talent
• Define and evolve MCP's edge across strategy types: market making, cross-platform arbitrage, event-driven momentum, statistical modelling on correlated contracts, and alternative data signal development
• Work with engineering to spec and prioritise infrastructure: execution systems, data pipelines, monitoring tools, and low-latency order management
• Contribute to investor reporting and, where relevant, capital raising — articulating the strategy's edge, risk profile, and performance clearly to institutional audiences

Requirements:

• Significant experience managing a live quantitative or event-driven trading portfolio with genuine P&L accountability — not just advisory or model-development roles
• Demonstrated edge in prediction markets, binary event trading, options, or closely related event-resolution domains
• Strong quantitative foundation: probability, Bayesian inference, statistical modelling, and portfolio construction
• Experience managing or mentoring junior trading professionals
• Clear, substantive engagement with the prediction markets ecosystem — platforms, mechanics, recent resolutions, structural inefficiencies. We will probe this in depth
• Undergraduate or postgraduate qualification in a quantitative discipline
• Experience operating on Polymarket, Kalshi, or equivalent platforms at meaningful scale
• Background in systematic commodity, macro, or multi-asset trading — our core competency and an area of genuine cross-pollination with prediction markets
• Familiarity with the analytics and data ecosystems around professional sports and major real-world event categories (politics, macroeconomics, climate)
• Experience with blockchain/DeFi infrastructure relevant to on-chain prediction market platforms
• Prior involvement in fund-level processes: investor relations, risk reporting, or strategy documentation
