openai.comCreate a landscape editorial hero image for this Studio Global article: What is former Twitter CEO Parag Agrawal’s argument that the internet’s advertising- and click-based business model cannot survive if AI age. Article summary: Agrawal’s central claim is that a web funded by human attention breaks when AI agents, rather than people, do most of the reading and searching. Agents do not view ads, develop brand preferences, or produce meaningful cl. Topic tags: general, news, general web, user generated, documentation. Style: premium digital editorial illustration, source-backed research mood, clean composition, high detail, modern web publication hero. Use reference image context only for broad subject, composition, and topical grounding; do not copy the exact image. Avoid: logos, brand marks, copyrighted characters, real person likenesses, fake screenshots, UI text, readable text, water
Parag Agrawal’s thesis is simple: the web’s current business model was built around human attention, but AI agents may become its most frequent users. If agents read, search, and synthesize information without generating page views, ad impressions, or meaningful clicks, the economic signal that supports publishers begins to disappear. 14

Agrawal’s company, Parallel Web Systems, is building infrastructure for what it describes as the web’s “second user”: software agents. Its proposal is not necessarily to replace human-facing websites, but to add an agent-native layer for search, retrieval, research, attribution, and payment. 40

Why clicks may stop being useful
Human search creates a relatively visible chain of value. A person searches, clicks a result, reads a page, sees advertising, and may return to a publisher or develop a preference for its brand. Clicks therefore serve two roles: they can generate revenue through traffic and help search systems infer relevance.
An agent behaves differently. It may query many sources, extract only the relevant passages, compare them, and deliver a synthesized answer directly to a user. The originating pages may receive no human visit at all. In that environment, a click does not fully capture whether a source supplied an important fact, confirmed a conclusion, or helped complete a larger task.
Agrawal’s argument is that the web will need to measure the usefulness of information to an agent’s task—not merely whether a person clicked a link. Parallel’s stated premise is that agents could use the web “1000x more” than humans, making the mismatch between agent activity and human-centered economics potentially significant. 14
What a “parallel web” would change
The proposed parallel web is an agent-focused infrastructure layer. Parallel’s APIs are designed for activities including web search, extraction, deep research, entity discovery, chat, and monitoring. Its documentation describes these tools as providing agents and developers with access to web information for research and other machine-driven workflows. 25
The central design change is the optimization target. Traditional web systems often use attention, links, and clicks as practical proxies for relevance. An agent-native system could instead ask whether a source helped an agent:
- find an accurate answer;
- complete a research task;
- resolve an entity or fact;
- support a decision or workflow; or
- improve the quality of a final response.
That would make source usefulness a task-specific signal rather than a general popularity score. Parallel has described direct agent feedback as an alternative to relying primarily on human click data for ranking and indexing. 44
45
This remains a company thesis, not an established standard for the wider web. It would require broad adoption by content owners, agent developers, search providers, and other infrastructure companies.
How Shapley values could pay publishers
Parallel’s proposed compensation model uses Shapley-style attribution. In simple terms, a Shapley value estimates how much additional value one participant contributes when several participants jointly produce an outcome.
Applied to web content, the question becomes: how much did a particular source contribute to an agent’s successful output, given the other sources available? A source that provides a unique fact or substantially changes the answer could receive more credit than a source that merely repeats information already supplied elsewhere. 16
29
This approach is intended to move compensation away from raw traffic or a flat licensing fee and toward marginal contribution. It also introduces difficult technical and governance questions: how should “success” be measured, how can attribution be calculated consistently, and how can the system resist gaming or manipulation? The available material describes the mechanism as a proposed model rather than a proven replacement for advertising.
What Parallel’s Index product does
Index is the publisher-facing part of the proposal. Parallel says it gives publishers, data providers, and independent creators visibility into how AI agents use their content, including which queries it helps answer, how often it is referenced, and how unique its contribution is to an agent’s work. Compensation is then tied to an estimate of the source’s Shapley value. 29
The launch included partners such as The Atlantic, Fortune, and PR Newswire, as well as business-information providers and independent creators, according to reporting on the product. 6
The significance of Index is that it attempts to address two problems at once: visibility and payment. Content owners could learn how agent systems rely on their work, while Parallel could create a mechanism for rewarding content that contributes useful information even when no human clicks through.
Parallel’s funding and business position
Parallel raised a $30 million seed round in January 2024, according to reporting on its subsequent financing. In November 2025, it announced a $100 million Series A at a reported $740 million valuation, co-led by Kleiner Perkins and Index Ventures. 11
33
In April 2026, the company raised a further $100 million Series B led by Sequoia Capital at a reported $2 billion valuation. Existing investors, including Kleiner Perkins, Index Ventures, Khosla Ventures, First Round, Spark, Terrain, and Abstract, were reported to have participated. 1

15
Parallel’s public materials position its APIs as infrastructure for developers building agentic products. Its Series A announcement identified companies including Clay, Sourcegraph, and Owner among its customers or users, but the available sources do not establish a comprehensive customer list or independently verified developer count. 40
Why Google Cloud matters
Parallel has also become an available search and grounding option for Google Cloud customers building enterprise agents with Gemini-related tooling. Reported integrations allow developers to use Parallel Search alongside Google Search for web grounding. 12
That partnership could give Parallel distribution through an established enterprise platform at the moment companies are experimenting with autonomous research and workflow agents. It also creates a strategic tension: Google is both a major distribution partner and a company with substantial search and AI infrastructure of its own. 5

Why Agrawal expects the shift within 12 to 24 months
Agrawal’s 12-to-24-month window is a forecast, not a measured consensus. The underlying bet is that improvements in models, tool use, and agent frameworks will make it practical for software to conduct many searches and subtasks on behalf of a single user. Existing cloud and API distribution could accelerate that adoption.
If agents begin generating far more web queries than people while returning synthesized answers instead of sending traffic to individual pages, the pressure on click-based economics could arrive before most consumers change their everyday browsing habits. Parallel’s “1000x” claim expresses the scale of that expected shift, but it should be treated as the company’s stated belief rather than a verified prediction. 14
The central uncertainty
Agrawal is proposing a new market design for an agent-dominated web, not announcing that the current advertising model has already failed. Index, agent feedback, and Shapley-based compensation offer a possible way to reward content that contributes to machine-generated answers, but they still depend on difficult attribution decisions and widespread participation.
The strongest version of the thesis is therefore conditional: if AI agents become the primary interface to online information, clicks may no longer be sufficient as the web’s economic and ranking signal. Parallel is betting that the replacement will be a system built around agent outcomes, source provenance, and payments for measurable informational contribution.
