“could you look for recsys competitions in russia and around the world which allows to participate everyone, i'm interested both in already finished, ongoing and planned competetions with prizes”
A multilingual web scan captured nine source rows that consolidate to seven distinct public recommender-systems competitions with prizes — three in Russia (Ozon, VK, Yandex) and four worldwide (RecSys Challenge 2024–2026, Netflix Prize) — spanning 2006 to 2026. Prizes are shown in their original currencies (₽ and $).
Nothing on this list could be confirmed as still accepting submissions on 2026-09-02. Your best lead is the RecSys Challenge 2026 Music-CRS ($2,000 pool) — the only current-year item found — but the captured sources give no submission deadline, so check the official RecSys Challenge 2026 page first. Also note: “open/public” does not always mean everyone worldwide — VK required participants to be 18+ and citizens of Russia or CIS countries. Re-check official rules before investing time.
| Competition | Region | Task | Dates (ISO) | Prize | Organizer | Eligibility | Status | Source |

Method: broad multilingual web scan of official competition pages, rules PDFs, event platforms and reputable announcements, captured as of 2026-09-02. Nine source rows consolidated to seven distinct competitions (two duplicate pairs merged). Prizes are quoted in original currency as stated by each source; blank fields mean the captured page did not state the value (“not recovered”), not that no restriction exists. The list is useful but not guaranteed exhaustive — old and planned contests are fragmented online and some pages omit or remove rules.
