Valve's ban on skin trading and case-opening site sponsorships for Counter-Strike 2 tournament broadcasts will take effect at Tier 1 events beginning with BLAST
Thank you for being a Ghacks reader. The post Valve's CS2 Skin Sponsorship Ban Takes Effect at Tier 1 Tournaments With BLAST Bounty Season 2 appeared first on gHacks.
Valve's ban on skin trading and case-opening site sponsorships for Counter-Strike 2 tournament broadcasts will take effect at Tier 1 events beginning with BLAST Bounty Season 2 2026, according to Dot Esports.
Although introduced in a December 2025 update to Valve's Tournament Operation Requirements, the rule is only now being enforced at the highest level.
It prohibits case-opening and skin trading site logos on player jerseys and broadcasts, but teams may retain these sponsorships outside of broadcasts.
The rule does not ban gambling or prediction market sponsors unconnected to Valve's game economy.
What Valve’s CS2 Sponsorship Ban CoversThe Tournament Operation Requirements (TOR) is the standardized rule set every organizer must follow to run a licensed CS2 event. The December 2025 update added a provision enforcing Section 2.4.e of the Limited Game Tournament License.
That section requires that organizers not distribute or display any content that violates Valve IP or the Steam Subscriber Agreement, giving game case opening sites and skin trading sites as examples.
It also states that organizers must not accept sponsorships from companies that generate revenue through activities relying on Valve's game economies, including key resellers or companies that interact with players' Valve game inventories.
In practice, this clause imposes two requirements on tournament organizers: it prohibits sponsorships from skin trading and case-opening sites, and it mandates that all related content, including logos on player jerseys, be excluded from broadcasts.
The restrictions target tournament broadcasts, not teams directly. Dot Esports notes that Valve does not explicitly ban skin sponsorships for teams, allowing them to promote these sponsors on their own social media. Compliance primarily involves removing skin site logos from player jerseys.
This change is evident at the BLAST Bounty Season 2 2026 online stage. During Team Vitality's match against Liquid, players wore Major-edition jerseys without the Skin.Club logo in its usual collarbone position. Skin.Club remains a Vitality partner and continues to appear on the team's social media during the event.
Dot Esports compares this situation to tobacco sponsorship bans in motorsport, where Ferrari used Mission Winnow branding as a surrogate for Marlboro.
Similar surrogate branding could appear in CS2 if brands seek to remain on player jerseys at high-profile events such as the IEM Cologne 2026 Major, which attracted over 2.75 million peak concurrent viewers.
Why Valve Is Enforcing the CS2 Sponsorship Ban NowAlthough Valve updated the TOR in December 2025, Tier 1 tournaments are implementing it only as of July 2026. Dot Esports attributes this delay to a TOR provision requiring Tier 1 tournaments to publish full "Additional Information" at least 10 months before the main event.
Tier 1 events announced after the December 2025 update are the first to meet the 10-month disclosure deadline and thus the first to be subject to the revised rule.
Tier 2 tournaments, with shorter announcement deadlines of two weeks to three months, implemented the rule earlier in the year. BLAST Bounty Season 2 is the first Tier 1 event to follow the new ruleset.
For teams and organizers, the practical effects are:
Dot Esports notes that traditional sports betting and prediction market sponsors unconnected to Valve's game economy are unaffected and may still appear on jerseys and broadcasts.
It remains unclear whether Valve will address the social media and surrogate branding loopholes used by teams like Vitality, or how strictly organizers will enforce borderline cases.
The future of CS2 sponsorships will depend on whether Valve further tightens the rules, which could encourage teams to pursue more betting and prediction market deals.
