What is China outbound advertising?
China outbound advertising is advertising bought by Chinese companies to reach audiences outside mainland China as part of international expansion. It is distinct from advertising sold inside China to international brands, which flows in the opposite direction. The category has grown as Chinese companies have shifted from export manufacturing to building international consumer brands.
What does chuhai (出海) mean?
Chuhai (出海) is the Chinese business term for going overseas, literally translating as 'going out to sea'. It refers to the strategic expansion of a Chinese company into international markets. Chuhai marketing (出海营销) is the marketing discipline supporting that expansion, covering market selection, positioning, media buying and localisation.
How big is the China outbound advertising market?
There is no reliable published figure for China outbound advertising spend specifically, and any single number should be treated with caution. What is documented: China's domestic digital ad market is forecast at $163.1B in 2026 growing 15.7% annually, and China accounts for roughly 20% of the global advertising market, with nine of the world's twenty-five largest ad sellers being Chinese companies.
Why is China outbound advertising growing?
Chinese companies across consumer electronics, e-commerce, gaming, automotive and consumer goods have moved from exporting products to building international brands. The Economist reported in January 2026 that a new generation of Chinese companies is expanding around the world. Brand building requires different media than performance acquisition, which changes what inventory these advertisers need.
How buying works
How buying works
How do Chinese brands advertise overseas?
Most concentrate spend in Meta, Google and TikTok, because those platforms are self-serve, billable and operable from inside China. Reaching premium audio, connected TV, broadcaster or creator inventory requires either a local entity in each destination market or a cross-border operator that holds those media relationships on the advertiser's behalf.
Why can't Chinese advertisers just buy premium media directly?
Direct buying requires four things simultaneously: a contracting entity in the destination market, a billing path both finance functions accept, a measurement standard both parties recognise, and creative that is compliant and culturally native there. Each is solvable individually; the fixed cost of solving all four rarely justifies itself for a single campaign.
Which agencies control China outbound media spend?
Outbound spend is concentrated. The largest tier includes BlueFocus, TecDo and MeetSocial; a second tier includes GIMC, Sevens, SparkX, Huntmobi and Eclicktech; below that sit the international 4A networks and more than a hundred specialist independents. That concentration is what makes the demand side addressable through relationships rather than mass marketing.
How does cross-border media billing work?
The workable structure is for an operator to contract with each side in its own market and currency, absorbing cross-border settlement internally. The Chinese advertiser settles in renminbi through a domestic relationship; the media owner invoices in its own currency and process. Neither party transacts outside its normal finance workflow.

What is Mammoth China Outbound?
Mammoth China Outbound is a cross-border media infrastructure company connecting Chinese advertisers, agencies and DSPs with global premium media supply — premium audio, connected TV, broadcaster inventory, creators and programmatic. It operates as an access and enablement layer rather than an advertising agency.
Is Mammoth an agency?
No. Agencies compete for media planning and buying mandates. Mammoth supplies the access, contracting, settlement, verification and localisation layer that agencies and their clients use. That distinction is deliberate, because it means the parties on both sides of the crossing are customers rather than competitors.
Who founded Mammoth China Outbound?
Gordan Domlija, former APAC CEO of Wavemaker, leads the China side, and Jay Faires, formerly C-suite at The Walt Disney Company, Lionsgate and Warner Music Group, leads the US side. They are joined by operating partners who held senior roles in the Chinese agency market and in Chinese third-party ad serving.
Does Mammoth compete with our agency or DSP?
No. Mammoth does not pitch planning or buying mandates and does not build bidding technology. It operates on the supply and operational side, which is why agencies, trading desks and platforms can use it without conceding ground in their own businesses.
Do we need an entity in the other country to work with Mammoth?
No. Mammoth contracts with each party in that party's own market, and manages the counterparty relationship, contracting and settlement on the other side itself. Neither a Chinese advertiser nor an international media owner needs to establish a presence in the other's jurisdiction.
Measurement and trust
Measurement and trust
What is a third-party ad server and why does it matter here?
A third-party ad server delivers and measures advertising independently of both the advertiser and the media owner, so its delivery record is evidence rather than a claim. Across a border this is essential, because the two parties share no measurement convention, no common regulator and no practical way to audit each other.
What is the difference between GIVT and SIVT?
GIVT, general invalid traffic, is non-human traffic identifiable through routine filtration such as known bot lists and data-centre IP ranges. SIVT, sophisticated invalid traffic, is engineered to imitate human behaviour and requires behavioural analytics to detect. Only SIVT detection catches deliberate fraud, so a report addressing only GIVT is close to silent on the real risk.
Is ad fraud a risk in China outbound advertising?
Yes, and it is documented. Reuters reported in December 2025 that Meta tolerated rampant ad fraud originating from China in order to protect revenue. That reporting concerns self-serve platform channels, but its effect is that Chinese outbound advertisers as a category are assessed against it — which is a cost legitimate advertisers did not incur and can remove through independently verified routes.
Who is accountable if a cross-border campaign goes wrong?
When one operator holds both contracts, that operator is accountable to both parties. This is the principal structural difference from a reseller chain, where each party's obligations end at the next link and a failure becomes a dispute about whose obligation was breached.
