Valkyrie Trading Interview Questions
A representative practice mix for Valkyrie's Quant Trader loop: fast probability and EV mental math, fair-value and bid-ask quoting, Kelly bet sizing, options payoffs, and classic brain-teasers.
Inside the Valkyrie Trading interview
Valkyrie Trading is a small Chicago-based options market maker and proprietary trading firm. Its Quant Trader interview leans on quick probability and expected-value reasoning, fair-value and quoting intuition, and disciplined bet sizing — the math you actually use while making markets.
What they test
The core is fast probability and expectation done in your head — card and dice odds, coin-flip races, and conditional EV under a payout structure (the tagged questions here are exactly this flavor). Around it sit fair-value and market-making problems (quote a two-sided market, read value off the book, price a simple option payoff) and bet sizing via the Kelly criterion.
The recurring shapes
Expect EV with optimal stopping (re-roll a die, when to take a wait), quoting against adverse selection (Glosten-Milgrom-style bid/ask), fair value before an event (a binary outcome you must price), and de-biasing a coin / simulating fairness. These mirror the daily job: estimate an edge, size it, and quote it without getting picked off.
How to approach
Anchor every answer in a clean expected value and a number you can defend out loud, then say which way you'd skew or widen a quote when information is one-sided. Keep arithmetic tight and state assumptions — at a small MM, the signal is how cleanly you reason under time pressure, not how exotic the model is.
The mix is mostly medium with a handful of easy warm-ups and one hard curveball, matched to how an options market maker actually interviews.
