Industry

What this industry sells

The Chinese social-media platform industry sells attention. Users pay nothing; they arrive for content, and the platform rents the resulting audience to businesses that want to be seen. Weibo describes itself as "a leading social media platform in China for people to create, discover and distribute content," and reports 567 million monthly active users and 252 million average daily active users in December 2025 [1]. The economic organizing principle follows from that: content is contributed largely for free by the audience itself and by influencers who want reach, the platform packages the attention into advertising inventory, and third-party agencies broker most of the money.

Three definitions carry the rest of this page. MAU and DAU are monthly and daily active users — the raw supply of attention. KOL means key opinion leader, the Chinese term for an influencer with a monetizable following; MCN means multi-channel network, the agency that manages KOLs at scale. Brand advertising buys awareness and is priced on exposure; performance advertising buys a measurable action and is priced on it. Weibo's filings describe the two as having converged, with demand from both large and small customers "shifting towards branding-plus-performance" [2].

Advertising and marketing revenues were $1,501.6 million of Weibo's $1,757.2 million total in 2025 — roughly 85 cents of every dollar. Value-added services, mainly membership and game-related services, supplied the remaining $255.6 million [5].

The value chain and where the money stops

Five stages sit between a post and a paid invoice. The unusual feature of this industry is that the largest cost input in adjacent media businesses — content — is largely donated at the top of the chain, because the people supplying it are paid in audience rather than cash.

Where the profit pool sits is visible in the cost line each player carries. Weibo's cost of revenues was $421.8 million in 2025, 24% of revenue [14]. iQIYI, which buys long-form video, spent RMB15,449.6 million on content alone, 57% of its revenue [15]. Bilibili's revenue-sharing costs, paid to distribution channels, game developers and creators, reached RMB12.1 billion, about 40% of revenue [16]. Hello Group paid RMB5,459.1 million in revenue sharing to broadcasters and talent agencies, 53% of revenue [17]. The distance between a platform whose content arrives free and one that buys or rents it is the largest single determinant of operating margin in this group.

How big the market is, and what the record supports

The corpus contains exactly one third-party sizing of the Chinese advertising market, and it is twelve years old. Weibo's 2014 IPO prospectus cited ZenithOptimedia's Advertising Expenditure Forecasts of September 2013: China was the world's third-largest advertising market at $37.2 billion in 2012, equal to 0.5% of GDP, against $161.2 billion and 1.0% of GDP in the United States. Online marketing had grown from $2.7 billion in 2008 to $7.0 billion in 2012 — 13.1% and 18.8% of total advertising spend — and was forecast to reach $15.9 billion, or 31.6% of the market, by 2015, a three-year compound rate of 31.4% [18].

Source: ZenithOptimedia Advertising Expenditure Forecasts dated September 2013, reproduced in Weibo's April 2014 IPO prospectus; 2012 is actual and 2013 to 2015 are forecasts made in 2013, stated in US dollars [19].

That series is a historical artifact, not a current market size. It establishes the shape of the industry's formative decade — online spend taking share from television at roughly three times the growth rate of total advertising — and nothing about 2026. No annual report, results release or transcript in this corpus contains a current market-size estimate, a market-share figure, or a third-party ranking of Chinese social platforms by advertising revenue. Any statement about Weibo's share of Chinese digital advertising would therefore have to come from outside the primary record, and this page does not make one. What the record does support is a comparison of what the individual listed players report.

The players that matter

Weibo names its competitors directly. As a media business it says major Chinese internet companies such as Tencent and ByteDance "compete directly with us for user traffic and user engagement, content talent and marketing resources." As a social platform it lists three cohorts: messengers such as Weixin/WeChat; multimedia apps "such as Douyin/TikTok, Kuaishou, Bilibili, Xiaohongshu (also known as RedNote), iQiyi, Tencent Video and Youku"; and news apps operated by Tencent and ByteDance [20]. In its advertising risk factor it names one vertical rival outright: "internet companies that offer digital media tailored to specific vertical, such as Autohome" [21].

A limitation sits at the top of that list. The two players Weibo names first — Tencent and ByteDance — have no filings in this corpus, and ByteDance is unlisted. The four peers whose annual reports are indexed are the second tier: Bilibili, iQIYI, Autohome and Hello Group. Each is a genuine competitor for Chinese attention and Chinese marketing budgets, and each monetizes that attention through a different mechanism, so the table below sets them side by side on that basis rather than as like-for-like comparables.

Sources: Weibo FY2025 Form 20-F income statement [22] and Business Overview [23]; Bilibili FY2025 Form 20-F income statement [24], revenue detail [25] and user metrics [26]; iQIYI FY2025 Form 20-F results of operations [27] and revenue detail [28]; Hello Group FY2025 Form 20-F results table [29]; Autohome FY2025 Form 20-F results of operations [30], net revenues [31] and mobile users [32]. Peer figures are translated from RMB at the convenience rate of RMB6.9931 to US$1.00 printed in each peer's own Form 20-F; Bilibili's advertising figure and Hello Group's non-VAS figure are derived from the RMB amounts at that rate.

Four observations follow, none of them a judgment on any share price. Operating margins in this group span 0.8% to 26.5%, and the ranking tracks content cost almost exactly. Revenue direction diverged sharply in 2025: Bilibili grew 13.1% while three of the five shrank. Advertising is not the primary business for two of the five — iQIYI sells subscriptions and Hello Group sells virtual gifts and memberships — so "competitor" there means competitor for user hours, and for advertising budgets only at the margin. And Autohome shows how a vertical specialist absorbs a category shock that a general platform feels only in part: its media services revenue fell 24.3% in 2025 "primarily due to reduced advertising spending by ICE automakers amid shrinking sales volumes in the ICE segment" [33].

Who pays, and who holds the purchasing power

The buyer side has restructured twice over. Until 2020 Weibo split its advertising customers into key accounts, which bought brand exposure, and small and midsize enterprises, which bought performance, and ran two sales forces to serve them. It merged the teams at the end of 2020 and stopped tracking the two groups separately from 2021, because the distinction between their needs "became less obvious" and demand from both had shifted towards branding-plus-performance [34]. The final year on the old basis showed the split plainly: key accounts $741.5 million and SMEs $592.7 million in 2020 [35].

The second restructuring is still running. The number of advertisers has fallen every year since 2019, while the average spend of those who remain has risen more than fivefold.

Sources: FY2021 Form 20-F for 2019 and 2020 [36]; FY2022 Form 20-F for 2021 and 2022 [37]; FY2023 Form 20-F for 2023 [38]; FY2025 Form 20-F for 2024 and 2025 [39].

Weibo attributes the shrinking count to "the churn of advertisers with relatively lower advertising budgets" [40]. The arithmetic is that the long tail of small self-serve advertisers that once defined social monetization in China has largely left this platform, and revenue now rests on a smaller set of larger buyers.

Purchasing power is exercised through agencies. Weibo treats an agency that signs the contract as its customer even though the advertiser is the beneficiary, pays those agencies rebates accounted for as variable consideration, and recognises revenue net of them [41]. The agency share of billings has fallen for three consecutive years.

Sources: FY2022 Form 20-F revenue disaggregation note [42]; FY2025 Form 20-F revenue disaggregation note [43].

Agencies billed 77.7% of advertising revenue in 2022 and 62.8% in 2025. Direct billings have risen every year since 2022 in both share and absolute dollars.

One buyer stands apart. Alibaba is both a related party and Weibo's largest single advertiser; its spend rose 49% to $173.8 million in 2025, 11.6% of advertising revenue, "driven by deeper collaboration between Alibaba and us during key e-commerce marketing windows," and Weibo notes that this spending "highly correlates to its own business operation, especially its marketing strategies, which fluctuates from time to time" [44]. Adding SINA and other related parties, $212.3 million of the 2025 advertising line, or 14.1%, came from related parties [45].

Demand is also concentrating in time. E-commerce platforms are "increasingly concentrating ad budget towards shopping festivals" [46], which deepens the industry's existing seasonality: spending is lowest in the first quarter because of the Lunar New Year holidays, and is further moved by events such as the FIFA World Cup and the Olympic Games [47].

The forces that divide the arena

Sources: FY2025 Form 20-F — competition [48], slowing internet community growth [49], creator dependence [50], agency rebates [51] and RMB receipts [52]; FY2022 Form 20-F, pre-install partner pricing [53]; FY2021 Form 20-F, channel partnership program [54].

The value-added services line shows what happens when one of these forces turns. Weibo's VAS once included live streaming: the Yizhibo business fell from $76.7 million in 2019 to $39.3 million in 2020 on intense market competition [55]. By 2025 the description of the line had narrowed to membership and game-related services [56]. The live-streaming profit pool did not leave the industry — Hello Group still runs an RMB10.2 billion value-added services business built on virtual gifting [57] — it moved to platforms built around it.

The regulatory stack

Regulation here is not a single licence but a stack of content, algorithm and commerce rules that attach to the platform. The recent additions carry hard effective dates.

Sources: FY2025 Form 20-F — microblog provisions and the amended Cyber Security Law [58], advertising regulation [59], algorithm recommendation and generative AI [60], AI labelling and livestreaming e-commerce measures [61]. Rows are ordered by the date the listed obligation takes effect.

The commercial consequence is that liability for what appears on the platform is shared with the platform rather than left with the advertiser. Weibo notes that where regulators find content objectionable they "may require us to limit or eliminate the dissemination or availability of such content or impose penalties, including the revocation of our operating licenses or the suspension or shutdown of our online operations," and that compliance cost rises with content and user volume [62].

Where the cycle sits

Chinese online advertising has run one deep downturn and one shallow, uneven recovery over the past five years. Weibo's advertising revenue grew 47% year on year in the second quarter of 2021 [63]. By the first quarter of 2022 growth was 10%, with management describing the overall advertising market as softening amid macro uncertainty, a resurgence of COVID-19 and lockdown disruptions [64] [65]. By the third quarter of 2022 advertising revenue was $393.4 million, down 27% and down 21% in constant currency, against what management called industry-wide pricing pressure [66] [67]. The twelve quarters since the trough are shown below.

Sources: Weibo quarterly unaudited results releases — 2Q 2023 [68], 3Q 2023 [69], 4Q 2023 [70], 1Q 2024 [71], 2Q 2024 [72], 3Q 2024 [73], 4Q 2024 [74], 1Q 2025 [75], 2Q 2025 [76], 3Q 2025 [77], 4Q 2025 [78], 1Q 2026 [79].

Sources: earnings call transcripts — 2Q 2023 [80], 3Q 2023 [81], 2Q 2024 [82], 3Q 2024 [83] and [84], 4Q 2024 [85], 1Q 2025 [86] and [87], 2Q 2025 [88], 3Q 2025 [89], 4Q 2025 [90], 1Q 2026 [91]; revenue levels from the quarterly results releases cited above.

Three features stand out. The recovery has been shallow rather than a cycle turn: eleven of these twelve quarters printed year-on-year advertising growth between minus 6% and plus 5%. Sector rotation has done most of the work, with automobile and internet services growing through the electric-vehicle transition and food-delivery competition while FMCG, food and beverage, apparel and personal care are repeatedly named as the drag [92] [93]. And currency now runs the other way: the 9% dollar growth reported for the first quarter of 2026 was 3% in constant currency [94], because revenue is received substantially in RMB while the accounts are kept in US dollars [95] [96].

Triangulating across the peers confirms the same macro but not the same outcome. iQIYI's advertising revenue fell 9.1% in 2025 "as some advertisers adjusted their advertising and promotion strategies in response to macro pressure" [97]; Autohome's media services fell 24.3% on internal-combustion vehicle weakness [98]. Bilibili's advertising revenue rose 22.8% [99], and its management described growth accelerating "from 20% year-on-year growth in the first quarter to 27% year-on-year growth in the fourth quarter," adding that "we continue to gain larger share of overall ad budgets" [100]. A flat market in which one player compounds in the twenties is a share shift, not a cycle.

Three currents running through this arena

Attention has stopped growing and is being re-sorted. Weibo's own filing records that with the growth rate of the overall size of the internet community slowing down, "the industry is evolving rapidly while witnessing rising competition for traffic and user time" [101]. At platform level that shows up as a peak and a fade: Weibo's December MAU rose from 573 million in 2021 to 598 million in 2023, then fell to 590 million and 567 million, while daily users held between 249 million and 260 million throughout.

Sources: Form 20-F user disclosures — FY2021 [102], FY2022 [103], FY2023 [104], FY2024 [105], FY2025 [106].

Bilibili over the same 2025 grew both DAU and MAU 8%, to 112 million and 368 million [107]. Part of Weibo's decline is a deliberate purchase decision: management attributes the sequential fall in the first quarter of 2026 to "ongoing rationalization of channel investment" — buying fewer pre-installed users [108] [109]. The split between users acquired and users retained is one of the few levers a platform in this industry controls directly, and its price is set by handset makers.

The buyer base is consolidating faster than the audience is shrinking. Advertiser count fell from 2.4 million in 2019 to 0.4 million in 2025 while average spend per advertiser rose from $593 to $3,385 [110] [111]. Total advertising revenue was roughly flat across those years, so composition rather than level is what changed. A base carried by fewer, larger buyers is more sensitive to individual budget decisions — Alibaba alone moved Weibo's advertising line by $57 million in 2025 — and correspondingly less exposed to the self-serve long tail that drives volume elsewhere in digital advertising.

AI has entered on three sides at once. As tooling, Weibo says it will "continue to drive the application of AI in ad creative generation and AI placement optimization" for clients of all sizes [112], and is using large language models to rework its recommendation feed and search products [113]. As demand, AI applications have become an advertising category in their own right: Bilibili's fourth-quarter 2025 call fielded a question about AI applications "ramping up their marketing spending recently" [114], and Weibo has flagged AI-application marketing as a reason user acquisition costs rose in the same quarter it was buying fewer pre-installs [115]. As regulation, the labelling measures effective 1 September 2025 and the livestreaming e-commerce measures effective 1 February 2026 make the distributing platform responsible for detecting and labelling AI-generated content, including where the file metadata carries no declaration [116]. The same technology is at once a cost saving, a source of new budget, a bidder against the platform for user attention, and a compliance obligation.

Definitions, comparability and what the record does not say

Three gaps in the record are worth stating plainly. There is no current third-party sizing of the Chinese online advertising market anywhere in this corpus; the only sizing is the 2013 ZenithOptimedia and iResearch data reproduced in the 2014 IPO prospectus, presented above as history. There are no filings for Tencent or ByteDance, the two competitors Weibo names first, so the largest part of the arena is visible only through Weibo's own characterisation of it. And no company in this group discloses advertising pricing, fill rate or ad load, so changes in monetization cannot be decomposed into price and volume from the public record — the closest available proxies are the advertiser count and average spend per advertiser that Weibo does publish.
