The Greymyst Open Quant Challenge

Greymyst OÜ operates with zero outside capital. We build and execute our own mathematical models on our own proprietary capital. We invite elite mathematicians, theoretical physicists, and low-latency C++20/Rust architects to solve open problems.

HONORARIUM: RESEARCH GRANT / CO-AUTHOR

PROBLEM STATEMENT: HAMILTON-JACOBI-BELLMAN STOCHASTIC CONTROL[STOCH-OPT-01]

Consider a market maker on CME WTI Crude options quoting bid/ask spreads under jump diffusion:

dS_t = μ dt + σ dW_t + J_t dN_t,    N_t ~ Poisson(λ),   J ~ N(μ_J, σ_J^2)

Formulate the terminal value function V(x, q, s, t) with quadratic inventory penalty γ q^2 and derive the asymptotic reservation spread as t → T under asymmetric order arrival intensities.
