About Big Sumo

The latest round of changes, announced on Wednesday, includes 15 existing roles being terminating, and 17 new positions established. These will impact several of its units, including the Data & AI department, two business units and finance teams.

Negotiations around terminations and the newly established roles are expected to last approximately three weeks.

These internal changes form part of wider organisational shifts following Veikkaus’ May 2026 decision to establish two subsidiaries: one dedicated to exclusive operations and another for the newly competitive, licence-based market.

What is Big Sumo?

Catalist initially received a list of fewer than 10 potential market makers from Kalshi. It has since completed agreements with close to 20 and is engaging with approximately another 20.

That growth reflects the expanding number and variety of sports contracts. ITF tennis is particularly dependent on official data because its more than 60,000 annual matches are not generally televised. Unofficially monitoring a tour moving between locations such as Bogotá and Bali would be difficult, Monk noted.

Streaming is also becoming part of the product. Monk said prediction market interfaces had moved beyond their earlier trading-led presentation to incorporate streams, player propositions and combinations resembling sportsbook bet builders.

How to play Big Sumo

The Streak Spins round awards eight spins in which every spin lands a paying result, with wilds extending the round. The second feature is a Fiery Jackpots bonus. It collects scatter activity in a treasure chest that can trigger a coin-based round revealing one of four fixed prizes, topping out at a 1,000x Mega.

Push Gaming is targeting players who value pace and predictability

That Mega sits close to the game’s overall ceiling. Flaming Streaks caps out at 1,150x the bet on a low-volatility math model, with the top RTP configuration reaching 96.35%. Those figures place the game firmly in low-risk, frequent-return territory rather than the volatile, big-multiplier design that defines much of the modern slots market.
