Optiver Compared With IMC for Trading Roles

Optiver runs a concentrated options floor while IMC has built out systematic trading, and floor risk versus coded strategy work should drive the choice.

Optiver and IMC are both options market makers with roots in Amsterdam and large trading floors in Chicago, and both hire heavily from graduates who excel at fast mental arithmetic under pressure. The practical difference for a new trader is that Optiver runs a concentrated options market making business built around floor style risk taking on a smaller number of products per trader, while IMC has diversified further into systematic and algorithmic trading, giving a junior trader more exposure to code driven strategy work earlier in their career.

Optiver's core business is quoting options and their underlyings on public exchanges, and the firm treats a trader's job as managing risk on a book in real time rather than building a long research thesis. The arithmetic testing inside the Optiver interview process exists because the desk genuinely requires repricing a position correctly within seconds during fast markets.

IMC covers a similar options market making core but has built out systematic and quantitative trading arms that run more like a research shop, developing and coding strategies that trade with less manual intervention. A junior joining IMC through the systematic path will spend more early time writing and testing code than a junior on a classical options floor, even though both firms sit under the same market making label.

Optiver measures a junior primarily on the profit and loss of the book they are given responsibility for, and that responsibility is handed over earlier than at many peers, sometimes within the first year. The feedback loop is fast and numeric, and a trader who is not producing tends to know it well before an annual review.

IMC measures a junior on a similar profit and loss basis on its market making desks, but on the systematic side the measurement shifts toward the quality and robustness of the strategies a junior contributes to, judged over a longer horizon because a systematic strategy's edge takes longer to prove out than a single day's options quoting.
