## Questions

### Who runs investment decisions at IMC?

IMC does not have a traditional CIO allocating to fund managers. All trading decisions are made by teams of traders and quantitative researchers operating within risk frameworks. The co-founders, Rob Defares and Willem Geusens, oversee the firm's strategic direction, but day-to-day risk-taking is decentralized across asset-class desks in Amsterdam, Chicago, and Sydney.

### Does IMC manage outside capital?

No. IMC deploys exclusively proprietary capital accumulated from the firm's own trading profits since 1989. There are no limited partners, no external fundraising rounds, and no managed accounts. This separates it structurally from both hedge funds and family offices that commingle outside assets.

### Which markets and instruments does IMC trade?

IMC makes markets in cash equities, equity options, index futures, ETFs, government bonds, foreign exchange, and digital assets. The firm is an active liquidity provider on over 100 trading venues across the Americas, EMEA, and Asia-Pacific. In crypto, IMC has operated on centralized exchanges since 2017 and helped seed liquidity for the first US Bitcoin futures ETFs.

### How does IMC's structure differ from Optiver or Citadel Securities?

All three are Dutch-descended proprietary market makers focused on technology and low-latency execution. Optiver remains Amsterdam-headquartered with a partnership structure; Citadel Securities is US-headquartered with significant external growth. IMC is privately held by its founders, operates as a single corporate group under IMC Holding Ltd., and has never taken outside investment — making it the most structurally insulated of the three.

### What is IMC's posture on digital assets?

IMC is an active, long-tenured liquidity provider in digital assets. It began quoting on cryptocurrency exchanges in 2017 and later supported regulated futures products. The firm views digital assets as a natural extension of its exchange-traded market-making model, not as a discretionary directional bet on token prices.
