Court pushes Reddit's fight to inspect Anthropic's AI records into October
The tentative ruling moves the protective-order hearing to October 1st, after two late-September motions to compel and a case conference.

Why it matters
The delayed ruling will set the terms under which Reddit can test its scraping claims without exposing Anthropic's model-development records to people involved in Reddit's AI business.
A San Francisco judge has tentatively delayed a hearing that could determine how closely Reddit's lawyers and experts may examine Anthropic's confidential AI records.
The San Francisco Superior Court case record moves Reddit's motion for a protective order and electronic-discovery protocol from September 10th to October 1st. Judge Joseph M. Quinn's posted tentative ruling says the matter was continued "on the court's motion" and gives no reason for the postponement.
The delay leaves Reddit and Anthropic without settled rules for handling some of the lawsuit's most sensitive evidence. Their dispute covers access by Reddit's in-house lawyers, restrictions on outside experts, the treatment of dataset names and other technical identifiers, automated document review, preservation of older data and limits on material printed from secure inspection environments.
Those questions will remain open while the discovery calendar moves ahead. Reddit has a motion to compel further responses set for September 28th. Anthropic has its own motion to compel further document responses set for September 29th. A case management conference follows on September 30th, one day before the new protective-order hearing date.
That sequence puts narrower disputes over discovery responses before the court resolves the broader rules governing who can inspect the evidence and how it must be handled.
Anthropic's trade secrets meet Reddit's litigation team
The protective-order fight centers on evidence Reddit says it needs to test its allegations that Anthropic scraped Reddit content without authorization and used it to train Claude. Anthropic argues that access to model-development records must be restricted to prevent its trade secrets from reaching people involved in Reddit's AI, licensing and product decisions.
Reddit's September 2nd reply memorandum says Anthropic wants to exclude Reddit in-house attorneys involved in decisions concerning AI models, machine-learning systems, licensing, data acquisition, partnerships, product development or related business strategy from material designated "Highly Confidential - Attorneys' Eyes Only."
Reddit argues that the restriction is too broad because Reddit and Anthropic do not sell the same products to the same customers. Anthropic's position is that Reddit's internal AI development and commercial interest in licensing data create a risk even if Reddit does not offer a public foundation model comparable to Claude.
The staffing consequence is concrete. Reddit says its in-house litigation team has three attorneys. If Anthropic's proposed restriction excludes one of them, Reddit calculates that the workload for each of the remaining two would increase by 50 percent.
The two sides also disagree over academic experts. Anthropic wants added scrutiny for researchers currently building competing foundation models or tools designed to attack, poison or compromise large language models. Reddit argues that the terminology could sweep in researchers who study model safety, vulnerabilities and limitations.
Dataset names could receive source-code treatment
Another dispute concerns records that mention filenames, dataset names, crawler names, modules, variables or log fields without containing source code itself.
Anthropic argues that some identifiers can expose proprietary information about how training data is assembled, filtered or processed. Anthropic wants the option to place those records under source-code-level controls, which can require review inside a secure inspection environment.
Reddit wants a stronger presumption that documents merely mentioning technical identifiers remain outside that restrictive tier. Reddit says Anthropic's approach could force lawyers to inspect routine emails under source-code procedures and make relevant records harder to review, print and use.
The electronic-discovery protocol raises separate questions about technology-assisted review. Reddit wants advance disclosure about automated systems used to search or filter records, including the general technology and the data sources involved. Anthropic favors narrower disclosures when software organizes or prioritizes documents without excluding them from production.
Preservation rules are also contested. Reddit wants potentially relevant legacy information retained. Anthropic opposes a blanket requirement for inaccessible or duplicative data when the same information remains available in active systems.
The hearing will not decide Reddit's claims
Reddit filed its complaint on June 4th, 2025, alleging breach of contract, unjust enrichment, trespass to chattels, tortious interference and unfair competition. Reddit claims Anthropic violated its user agreement through unauthorized automated access to content used for Claude. Anthropic disputes the allegations.
Anthropic moved the lawsuit to federal court, arguing that federal copyright law preempted Reddit's state-law claims. A federal judge returned the case to San Francisco Superior Court on March 30th, 2026, finding that Reddit alleged contractual, technical and privacy-related obligations beyond rights covered by copyright law.
The October 1st hearing, if it proceeds on that date, will address the mechanics of discovery rather than whether Anthropic unlawfully obtained or used Reddit content. Its outcome could still shape Reddit's ability to reconstruct how its data entered Anthropic's systems and Anthropic's ability to keep Claude's technical internals away from lawyers and experts connected to Reddit's AI work.
