Which CS2 teams have betting sponsors? Valve's two classes

Most top CS2 teams have betting sponsors: Esports Charts’ February 2026 count found betting, casino or poker brands as title partners on nine of ten Americas teams and 12 of the top 20 European teams. Since December 2025, Valve’s rules bar skin-gambling and case-opening sites from jerseys at all events; cash sportsbooks are not named in the requirements file.

The question has two halves now, and the trade press reports one deal at a time without saying which half a brand belongs to. Below: the line, then the teams, then what this desk could and could not read.

Are betting sponsors allowed in CS2?

Yes, in the cash-book sense. Valve’s Tournament Operation Requirements, read by this desk on 14 September 2026, contain no wording about betting or gambling at all. They bind every operator, Ranked or Unranked, to clause 2.4.e of the Limited Game Tournament License, which Dust2.us reported in December 2025 as the mechanism barring case-opening, skin-trading and skin-gambling sites from jerseys and broadcasts.

The exact sentence in Valve’s rules file is that all operators “must abide by 2.4.e of the Limited Game Tournament License, which relates to displaying content that violates Valve IP or the Steam Subscriber Agreement.” The licence page serves Steam chrome to a plain request, so this desk has not read 2.4.e in Valve’s words; the skin-site reading rests on Dust2.us’s quotation of it.

Did Valve ban gambling sponsors from CS2 jerseys?

Not gambling sponsors as a class. Per Dust2.us’s December 2025 report, the update forced Unranked events to match Ranked events in carrying no logos, promotion, activations or advertisements for case-opening, skin-trading or skin-gambling sites. Cash sportsbooks and casinos are not named in the TO requirements this desk read.

So the two classes are: cash sportsbooks, casinos and poker brands, which the TO requirements do not mention; and case-opening, skin-trading and skin-gambling sites, which are out of the jersey slot at every sanctioned event. Compare the Riot picture, where a sponsor category was opened with rules attached. Valve closed one category and said nothing about the other.

How many CS2 teams have betting sponsors?

Esports Charts’ analysis, dated 16 February 2026, is the only roster-wide count this desk found. It sampled the top 20 European and top ten Americas and Asian teams in the Valve Regional Standings and looked at the jersey front. Nine of ten Americas teams carried a betting operator, crypto casino or poker platform there. Twelve of 20 European teams did; only four had a non-gambling title partner, Team Falcons among them. Asia had fewer, with The MongolZ named as one still carrying a betting-related brand.

Two cautions. The count is seven months old as of this writing and carries a correction on Team Spirit’s title sponsor. It also lumps cash books, crypto casinos and poker into one bucket and, in the text this desk read, never mentions the Valve update, so it cannot say how many of those 21 placements are now barred by it.

The team-by-team record, as read on 14 September 2026

The plan was a sponsor table sourced row by row from team and operator pages. It could not be built, so this is a provenance table instead: who is reported with whom, which class, and what this run got back.

CS2 teams and reported betting sponsors — what this desk could read, 14 September 2026

Team Vitality x Tradeit	Skin-trading class. Team's own press page read at 200: dated Paris, 16 October 2023, names Tradeit the Official Skin Trading and Skin Marketplace Partner, jersey slot below player names from IEM Sydney, brokered via Prodigy Agency. Silent on whether the placement survived December 2025.
Team Vitality x Stake	Cash-book class, as reported. Trade headlines describe a multi-year international betting partnership announced at IEM Cologne 2025. Vitality's announcement URL redirected to the shop homepage; Gambling Insider answered 403. Reported, not read.
Ninjas in Pyjamas x Rainbet	Casino class, as reported. A May 2025 trade headline scoped the jersey deal to the remainder of 2025. NiP's partners page opened at 200 but shows logos with no names in the text. Reported, not read, and time-limited by its own wording.
MOUZ x Fonbet; FlyQuest x Leon.bet	Cash-book class, as reported. Named only in an esports.gg headline on IEM Cologne 2025 jerseys; that page answered 403 to this run. Reported, not read.
FaZe Clan x Rollbit	Casino class, as reported. A trade item on a 2026 jersey carrying the Rollbit logo failed to connect. Reported, not read; no deal value printed.

One row is fully sourced, and it is a skin-trading sponsor announced two years before the rule that now keeps that class off the jersey. Everything else is a headline this desk could not open.

Which CS2 teams are sponsored by Stake?

Team Vitality is the pairing the trade press reports, a multi-year international betting partnership announced around IEM Cologne 2025. This desk could not read it: Vitality’s own announcement URL redirected to the shop homepage on 14 September 2026, and Gambling Insider answered 403. Treat it as reported, not confirmed.

Which CS2 teams are sponsored by 1xBet?

None that this desk could source. 1xBet appears in this query’s results only inside SportsBoom’s bookmaker listicle, which names no team sponsorship, and in Esports Charts’ graphic, whose per-team labels the text does not reproduce. No team or operator page read in this run names a 1xBet CS2 deal.

Why do so many CS2 teams have betting sponsors?

Esports Charts’ answer is structural: an open circuit, flagship events with millions of viewers, and jersey fronts as the most visible sponsorship real estate. Add Valve’s rule, which shuts skin sites out of that slot but leaves cash books in it, and the incentive points one way. Nine of ten Americas teams in the February 2026 sample had a gambling title partner.

The rest sits where the circuit’s money does: ESL Pro Tour generates the rights value and the data-rights economy prices the matches. Teams sell the one asset they own outright, the front of the shirt.

Both columns

Valve's jersey rule as a sponsorship regime — the short version

Pros

It draws a real line: case-opening, skin-trading and skin-gambling sites are out of the jersey and broadcast slot at every sanctioned event, per Dust2.us's account of the December 2025 update
It applies uniformly: the TO requirements bind Ranked and Unranked operators alike to clause 2.4.e, so a tier-two LAN cannot become the loophole
Teams had warning: Dust2.us reported skin logos already missing from several jerseys at the StarLadder Budapest Major

Cons

The rule never says the words: the TO requirements name no gambling, betting or skin site; the restriction lives in a licence clause this desk could not read in Valve's own text
Cash sportsbooks and crypto casinos are untouched, so the front of the shirt stays a gambling billboard on most top teams per the February 2026 count
No per-team compliance list exists anywhere this desk could read; which sponsors were dropped at Budapest is one unattributed sentence in one trade report
Team press pages are an unreliable record: Vitality's Stake announcement redirects to a shop and NiP's partners page is logos with no names

Verdict

The roster answer, then: most of the top CS2 teams, per the only count that exists, with one class of sponsor now off the shirt and the other still on it. A book’s logo on a jersey is not a recommendation. 18 and over, licensed sportsbooks only, availability varying by jurisdiction, a limit set before the map loads.
