We prove that, with high probability, any 2‐edge‐coloring of a random tournament on n vertices contains a monochromatic path of length \Omega(n/ \sqrt{log n}). This resolves a conjecture of Ben‐Eliezer, Krivelevich, and Sudakov and implies a nearly tight upper bound on the oriented size Ramsey number of a directed path
