Summary

Performance Analysis
Zhihu’s Q1 results spotlight a business in active transformation, as the company prioritized profitability and platform quality over short-term revenue growth. Total revenue declined year-over-year, led by a sharp drop in marketing services revenue, as Zhihu continued its shift away from low-quality, high-churn advertising. Despite these headwinds, the company achieved a notable expansion in gross margin, up 5.2 percentage points to 61.8%, reflecting both improved operational efficiency and the positive impact of AI integration on cost structure.
Operating expenses fell significantly across all major categories, with salary, marketing, and R&D costs down double digits, driven by disciplined investment and ongoing automation. Non-GAAP net income turned positive for the second consecutive quarter, a milestone for Q1 since IPO, underscoring the leverage in Zhihu’s model as it pivots to higher-value content and paid services. The paid membership business demonstrated resilience, with sequential growth in subscribers and stable revenue, while vocational training continued to contract as part of a strategic overhaul.
- Advertising Model Reset: Marketing services revenue fell 40% YoY, with management actively reducing low-quality ad inventory and prioritizing expert-driven content partnerships.
- Paid Membership Stability: Average monthly paid members rose 1.2% sequentially to 14.2 million, supporting recurring revenue and user engagement.
- Cost Structure Reengineered: Operating expenses declined 34% YoY, with notable savings in G&A and R&D, highlighting the impact of automation and focus on core initiatives.
Cash and equivalents remained robust at RMB 4.8 billion, providing ample flexibility for buybacks and continued investment in AI and content platform evolution.
Executive Commentary
"This milestone reflects the continued execution and enhancement of our operating strategy, as well as the increased operating leverage enabled by AI integration... Our trustworthy content and active professional creator ecosystem enhanced the commercial appeal of our brand and monetization potential."
Zhou Yuan, Founder, Chairman, and CEO
"For our marketing services, it has been evidence that relatively low quality marketing content consumption has dropped to a very low level. And we are now seeing accelerated momentum in both client mix optimization and commercial product updates. On top of that, AI is unlocking new marketing product opportunities."
Wang Han, Chief Financial Officer
Strategic Positioning
1. AI-Driven Content and Expert Network
Zhihu’s core strategic lever is integrating AI with its expert network, creating a defensible, high-trust content ecosystem. The launch of contributor attribution features and public knowledge bases is designed to amplify expert influence and reduce AI hallucination, positioning Zhihu as the preferred platform for professional, credible content in the era of large language models (LLMs).
2. Monetization Model Realignment
The company is actively phasing out low-yield, low-quality marketing inventory in favor of premium partnerships and AI-driven ad solutions. This transition is compressing near-term ad revenue but is expected to yield higher-margin, more sustainable monetization as brands seek credible, expert-driven platforms for AI-powered marketing.
3. Paid Membership and Content Diversification
Paid membership remains a resilient revenue pillar, with growth in both short-form and long-form premium content driving user engagement and conversion. Initiatives like the Yanyan Story Marathon and original audio dramas are broadening the appeal and stickiness of the platform, reinforcing Zhihu’s leadership in the paid reading and premium knowledge space.
4. Vocational Training Model Shift
Zhihu is transitioning its vocational training business from a subject-based model to a more interactive, community-driven approach, leveraging its creator network to deliver expertise and social learning rather than commoditized courses. This is expected to improve profitability and operational efficiency over time.
5. Capital Allocation and Shareholder Returns
With a new buyback authorization for up to 10% of outstanding shares and a strong cash position, management is signaling confidence in the long-term value of the platform and its ability to generate sustainable returns as the business model matures.
Key Considerations
This quarter underscores the tension between short-term revenue compression and long-term platform quality, as Zhihu rewires its business for the AI era. Investors should track the pace of margin expansion, the success of new content and expert-driven initiatives, and the ability to scale higher-quality revenue streams as legacy segments are phased out.
Key Considerations:
- AI Integration as Strategic Moat: Early traction in AI-powered content attribution and public knowledge bases is building a unique competitive advantage.
- Ad Revenue Reset Is a Double-Edged Sword: While compressing near-term growth, the shift away from low-quality ads is enhancing brand trust and CPMs.
- Paid Membership Is Core to Recurring Revenue: Stability and engagement in this segment provide ballast as other segments transition.
- Content Ecosystem Health Metrics Improving: Increases in creator activity and user engagement signal a healthier, more vibrant platform.
- Buyback and Cash Buffer Mitigate Execution Risk: Ample liquidity and active repurchases support valuation during the strategic transition.
Risks
Execution risk remains high as Zhihu navigates a complex business model reset, with legacy revenue contraction outpacing immediate gains from new monetization models. Competitive pressures in both content and AI search, potential regulatory scrutiny on content authenticity, and the pace of user engagement improvements are key variables. Management’s focus on quality over quantity could limit top-line recovery in the near term.
Forward Outlook
For Q2, Zhihu indicated:
- Continued focus on profitability and margin expansion as the mix shifts toward premium content and expert-driven services
- Further rollout of AI-powered knowledge bases and deeper integration of expert attribution features
For full-year 2025, management maintained its commitment to:
- Driving sustainable growth and profitability through disciplined investment, enhanced commercialization, and platform quality
Management highlighted several factors that will shape the year:
- Scaling AI and expert network initiatives to drive new user and brand engagement
- Ongoing cost discipline and operational efficiency as core levers for bottom-line strength
Takeaways
Zhihu’s Q1 performance underscores a pivotal transition from volume-driven legacy revenue to a higher-quality, AI-enabled content platform.
- Strategic Margin Expansion: Gross margin gains and cost discipline are cushioning the impact of legacy ad revenue declines, validating the new platform model.
- AI and Expert Network as Differentiators: Early success in content attribution and public knowledge bases is building a moat against commoditized content platforms.
- Watch for Monetization Inflection: Investors should monitor the pace at which new premium content and AI-driven advertising can offset legacy contraction and drive sustainable growth.
Conclusion
Zhihu’s Q1 2025 results mark a clear inflection in its business model, with gross margin expansion and disciplined cost management providing a foundation for long-term value creation. The company’s focus on AI-enabled, expert-driven content is building a differentiated platform, but near-term revenue pressure and execution risk remain. The next phase will test Zhihu’s ability to monetize its evolving ecosystem at scale.
Industry Read-Through
Zhihu’s strategic pivot highlights an industry-wide shift toward quality, trust, and defensibility in digital content platforms, as AI commoditizes generic information and advertisers seek credible environments for engagement. The move away from low-quality ad inventory and the integration of expert attribution are likely to become best practices across content and knowledge-sharing platforms. Sector peers should note the margin benefits of disciplined cost management and the risks of revenue volatility during business model transitions. The evolution of AI-powered content curation and monetization will be a key theme for all digital media and community-driven businesses in the coming quarters.
