Brazil's competition tribunal has closed its review of Amazon's minority stake in Anthropic and their collaboration agreements, finding no gun jumping on the facts it examined, according to CADE's own release
On CADE's account the relator confined the decision to the stakes, contracts and clauses actually examined, and said future changes to the relationship could justify a fresh look.
Bottom line: A closure decision reported by CADE itself on 23 September 2026. We have not read the vote. CADE says the case closed with no gun jumping infringement, and also says the closure is no competition immunity for the Amazon and Anthropic collaboration.
Who this affects: Brazilian competition counsel, M&A and corporate development lawyers structuring minority investments in AI developers, and counsel negotiating compute supply, technology development and model distribution agreements between cloud providers and AI labs.
Issue date: Decided at the Tribunal session of Wednesday 23 September 2026. CADE's release was published the same day at 12h28.
What changed: On CADE's account, the 2023 minority acquisition was a concentration act but fell below the turnover threshold for prior notification, and the collaboration agreements were not an associative contract under Resolucao CADE 17/2016.
Analysis: The release gives a full section to the limits of the ruling. It records the relator saying later changes could justify a new review and that execution of the contracts could still be investigated as conduct.

What CADE says the Tribunal decided
Everything in this section comes from CADE's own release of 23 September 2026, the authority's account of its own decision. We have not read the relator's vote, so these are CADE's statements about its decision, not quotations from it.
According to the release, the procedure was opened to check whether Amazon's acquisitions of equity stakes in Anthropic, and contracts covering compute infrastructure, technology development and the distribution of AI models, should have been notified to CADE in advance.
On the equity stake, CADE says the relator, Councillor Jose Levi Mello do Amaral Junior, concluded that Amazon's 2023 minority acquisition was a concentration act but was not subject to prior notification, because Anthropic's turnover in Brazil in the year before the deal did not reach the minimum set by Lei no. 12.529/2011. The release does not state the figure.
On the agreements, CADE says the relator found they were not an associative contract under Resolucao CADE no. 17/2016. The release adds a time qualifier. Although the agreements create relevant commercial ties, no common venture or sharing of the risks and results of the activity was identified "nesse momento", at this moment. The Tribunal concluded there was no gun jumping and closed the procedure.
The limits CADE placed on its own ruling
The release gives a whole section to what the closure does not decide. Its first sentence, in the original Portuguese, is reproduced as the quotation for this piece.
Our translation of the release, not an official one: "Under the terms of the vote, the relator stressed that the decision is limited to the equity interests, contracts and clauses actually analysed in the proceeding, and that the closure does not mean that every minority investment or collaboration agreement between computing infrastructure providers and artificial intelligence developers is excluded from competition control."
CADE says the relator determined that future changes in the relationship between the companies could justify a new assessment, and that the execution of the contracts could be investigated if it produces or could produce harmful effects on competition. The release closes by saying the closure is no competition immunity for the Amazon and Anthropic collaboration.
It also lists concerns such partnerships could raise depending on their configuration, including technological or commercial dependence, switching costs, access to competitively sensitive information and possible restrictions on rivals. Those are named as possibilities. The release does not say CADE found any of them here.
What the case file shows about the route to this decision
The public case file on CADE's SEI system carries the relator's report, signed on 21 September 2026. A report sets out the procedural history and the parties' positions. It is not the decision.
According to the report, CADE's General Superintendence ordered the APAC opened by Despacho SG no. 1129/2024, signed on 10 October 2024. Its Nota Tecnica no. 9 of 31 March 2026 sent the case to the Tribunal. The case went to the relator on 9 April 2026, was placed on the agenda of the 265th session on 13 May 2026 and withdrawn at his request, and was placed on the 272nd session agenda for 23 September 2026.
The report also records Amazon's arguments, which are a party's positions and not findings. Amazon argued that Anthropic had no Brazilian turnover at or above R$75 million in 2022, 2023 or 2024, that the investments did not meet the minority acquisition notification criteria in articles 10 and 11 of Resolucao CADE no. 33/2022, and that the collaboration agreements were not an associative contract. The report contains commercial detail marked restricted to CADE and the parties.
Three case numbers for one case
CADE's release gives the case as APAC no. 08700.007165/2024-11. CADE's agenda for the 272nd session lists the Amazon and Anthropic APAC as no. 08700.005962/2024-55, and so does the public SEI case file that holds the relator's report. The relator's report itself carries a third number in its heading, 08700.007315/2024-88, while the SEI footer on the same document gives 08700.005962/2024-55.
We report the conflict rather than choose between the numbers. Anyone searching SEI for the vote should try 08700.005962/2024-55 first, since that is where the report sits, and check the other two numbers if the vote does not appear there.
What we did not verify
What we opened: CADE's release of 23 September 2026, read in full in Portuguese; the agenda of the 272nd Ordinary Judgment Session, signed on 16 and 17 September 2026; the public SEI index for process 08700.005962/2024-55; the relator's report of 21 September 2026; and a certificate of a 17 September 2026 meeting with Amazon's counsel, both from that file.
What we did not open: the relator's vote and any judgment certificate or minutes of the 272nd session, none of which appeared in the public SEI index when we checked; the session audio; the documents marked restricted; and CADE's 2024 announcement on reviews of big tech acquisitions of AI startups, which we saw only as a search listing. The upgrade trigger for this piece is publication of the vote in SEI under 08700.005962/2024-55 or 08700.007165/2024-11.
What we refuse to claim: we do not say how any councillor voted or whether the decision was unanimous, because the release does not say. We do not describe the Tribunal's reasoning beyond what the release attributes to the relator. We do not call this the first Brazilian ruling on a cloud and AI partnership, and we do not state the turnover threshold as a finding, because the R$75 million figure appears only in Amazon's arguments as the report records them.
Informational analysis for working professionals, not legal advice. Confirm how any rule applies to your situation with qualified counsel.
Treat this as a case-specific closure limited to the documents examined, not a safe harbour for a deal structure. On CADE's account the relator tied the outcome to the stakes and clauses actually examined and to what was visible at this moment, and said later changes could justify a new review. If you amend a compute, development or distribution agreement with an AI developer in which your client holds a stake, reassess notification and conduct risk against the amended terms.

FAQ
Did CADE approve the Amazon and Anthropic partnership?
Not in those terms. CADE says its Tribunal closed a procedure that asked whether Amazon's acquisitions of equity stakes in Anthropic and the collaboration agreements should have been notified in advance, and found no gun jumping. Its turnover conclusion, as the release reports it, concerns the 2023 minority acquisition. CADE also says the closure is no competition immunity.
Why was the minority stake not notifiable?
According to CADE's release, the stake was a concentration act but Anthropic's turnover in Brazil in the year before the deal was below the minimum in Lei no. 12.529/2011. The release does not give the figure.
Could CADE look at the relationship again?
Yes, on CADE's account. The release says future changes in the relationship could justify a new assessment and that execution of the contracts could be investigated as conduct if it produces or could produce harmful effects on competition.
Has the decision itself been published?
We did not find the vote in the public SEI index for 08700.005962/2024-55 when we checked. That index held the relator's report of 21 September 2026. We have not established whether the decision was published elsewhere. CADE's release and the session agenda also give different case numbers.
