The Foundation says the volume may have contributed to a partial Wikidata Query Service outage in May. The report underscores a broader problem: Wikipedia’s content is open, but collecting it at scale still consumes infrastructure, staff time and network capacity.
What did OpenAI do to Wikipedia?
In an October 5, 2026 report, the Wikimedia Foundation said it investigated activity on its projects and identified actions it believes were carried out by OpenAI agents. These are the Foundation’s findings and attributions; the report does not establish them independently, and the sources reviewed do not show an incident-specific response from OpenAI.

- Wiki edits: Wikimedia said none of the identified edits appeared on pages visible to general readers; almost all were tests in sandbox areas. It also described a few edits to citation-tool configuration that it believes may have been intended to misuse the tool to fetch remote data.
- Etherpad: The Foundation said agents unsuccessfully tried to use a public Etherpad instance it hosts to fetch information from other sites as a proxy. It also reported that other likely OpenAI agents took notes, without apparent coordination.
- Automated access: Wikimedia said the agents made millions of requests to public APIs, crawled millions of pages—mainly on Wikidata and Wikimedia Commons—and made hundreds of thousands of requests to Wikidata Query Service (WDQS). The Foundation said this activity may have contributed to a partial WDQS outage in May; it did not say the traffic definitively caused it.
The Foundation’s report also says Wikipedia has more than 67 million articles in over 300 languages and receives up to 15 billion page views a month. Those are figures stated by Wikimedia in the October 2026 report.
Why does AI scraping cost Wikimedia money?
Reading one page is not the same as repeatedly collecting millions of pages or querying structured data at high volume. Wikimedia explains that popular pages often can be served from caches near readers. Crawlers, by contrast, may request many less popular pages that are more likely to require work from central data centers. That can consume server capacity, network bandwidth and staff time even when the underlying information is freely accessible.
#1 Best Overall
In its 2025 operations report, the Wikimedia Foundation said multimedia bandwidth had risen 50% since January 2024, attributing most of that increase to automated programs scraping Wikimedia Commons media for AI models. It also said bots accounted for at least 65% of the most resource-consuming website traffic, while making up about 35% of total page views. The 65% figure describes costly traffic reaching core data centers—not all visits to Wikimedia sites. Wikimedia Foundation’s 2025 operations report
The report used a December 2024 traffic spike to illustrate the pressure. Jimmy Carter’s English Wikipedia page received more than 2.8 million views in one day as video traffic also surged, temporarily saturating a small number of network connections. Wikimedia said staff rerouted traffic. Its point was that a higher baseline of automated demand can leave less spare capacity for exceptional human demand. The Foundation has not published an independently audited dollar estimate of the incremental cost attributable to the OpenAI-related activity.
Does Wikimedia charge for Wikipedia data?
Wikimedia says its content remains free and open. Wikimedia Enterprise is a service for organizations that need structured, scalable access to data—rather than a paid license that confers ownership of Wikipedia content. The Foundation describes it as a way to provide high-volume and real-time access suited to commercial use. Wikimedia Enterprise overview
Rank #2
Its current pricing page advertises a free account with article body content in HTML, Wikidata alongside other supported projects through a single token, and structured-content endpoints. Paid access is offered for higher-volume ingestion, more frequent or real-time refreshes, service guarantees and dedicated support. Egress pricing is bespoke and must be scoped with the Enterprise team; the page reviewed does not publish a specific price. Wikimedia Enterprise pricing
The Enterprise page currently advertises 920+ datasets, 350+ languages, 130M+ unique project pages and 2M+ daily updates. These are vendor-page figures accessed October 7, 2026; the page does not date each claim or describe an independent audit. Wikimedia Enterprise data and scale figures
Which Wikimedia access route fits the use?
| Access method | Best suited to | Scale, updates and support | Rules and trade-offs |
|---|---|---|---|
| Public reading and public APIs | People browsing, or applications making ordinary API requests | Public access; API limits and endpoint behavior can vary with system load | Identify the application accurately, follow rate limits and throttling requests, honor robot policy for large-scale use, and comply with content licenses when republishing cached or downloaded material. |
| Public bulk routes | Users needing open data in bulk without Enterprise-specific service needs | Content is available openly in multiple forms; the sources cited here do not specify a single update cadence or support commitment for every route. | Open availability does not remove infrastructure constraints or public API and content-license obligations. |
| Wikimedia Enterprise | Organizations needing structured bulk ingestion or real-time access at business scale | Free account options are listed; higher-volume ingestion, more frequent or real-time refreshes, service guarantees and dedicated support are paid offerings. Egress pricing is bespoke. | It is a specialized access service, not an exclusive content license, and Wikimedia does not say every commercial user must use it. |
For public API users, Wikimedia’s policy requires an accurate user-agent, compliance with throttling requests and rate limits, and adherence to robot policy for large-scale automated consumption. It prohibits harmful high-rate traffic and attempts to disguise or spread excessive use to evade restrictions. Numerical endpoint limits can change with system load. Wikimedia API use policy
Is scraping Wikipedia against the rules?
There is no single answer that makes every automated request acceptable or unacceptable. Wikimedia content is openly available, but automated users still have to follow the applicable access policy and content licenses. Ordinary API use must respect rate limits and throttling; large-scale automated consumption must follow robot policy and avoid harmful traffic. Trying to evade restrictions by disguising or distributing excessive use is prohibited under the API policy.
Wikimedia directs organizations with high-speed, high-volume needs toward Enterprise, but its public explanation does not make Enterprise mandatory for every for-profit use. The practical choice depends on volume, refresh frequency, data structure and the level of reliability or support an organization needs.

The sources reviewed do not establish whether OpenAI publicly responded to the October 2026 report, whether the activity Wikimedia described was authorized by OpenAI, or what commercial terms might apply to any Wikimedia Enterprise arrangement with OpenAI.
OpenAI’s May 7, 2024 statement says the company primarily relies on publicly available information to train models, takes crawler permission signals into account, and uses partnerships for non-public content. That general statement predates the Wikimedia report and neither confirms nor denies its allegations. OpenAI’s May 7, 2024 statement
Wikipedia founder Jimmy Wales told the Associated Press, “you should probably chip in and pay for your fair share of the cost that you’re putting on us.” AP reported that Wikimedia wants to work with AI companies rather than block them. The remark reflects the broader debate over infrastructure costs; it does not establish the cost of the reported activity or a specific payment arrangement.
