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

What CADE says the Tribunal decided

Everything in this section except where the ata is named 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.

CADE's ata of the 272nd session, published on 29 September 2026, records the outcome as item 1: the Plenary decided "por unanimidade", unanimously, to archive the APAC. In the ata's words: "O Plenário, por unanimidade, determinou o arquivamento do APAC, considerando que as operações não são de notificação obrigatória ao Cade". The ata gives two grounds. The collaboration agreements do not fall within the cases in art. 90 of Lei no. 12.529/2011, and the minority stake does not meet the turnover criterion in art. 88, II of the same law. The ata does not use the term gun jumping, and it cites the relator's vote without reproducing it.

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

When we first wrote this piece, the public case file on CADE's SEI system carried 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.

Case numbers: what each source says

CADE's release as it stands now (published 23 September 2026, updated 24 September 2026 at 11h55) gives the APAC as no. 08700.005962/2024-55, in the text and in its link to the case. The agenda of the 272nd session and the ata of that session give the same number.

Our first version of this piece, written on 24 September 2026, recorded that the release cited APAC no. 08700.007165/2024-11, and that the relator's report carried a third number in its heading, 08700.007315/2024-88, while the SEI footer on the same document gave 08700.005962/2024-55. We have not re-opened the report. We cannot see the earlier version of the release, so we cannot confirm what it said before the update, or whether the update changed the number. The current release, the agenda and the ata agree on 08700.005962/2024-55, and we use that number.

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 ata of that session, published on 29 September 2026; and, in our first version, 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, which we have not re-opened.

What we did not open: the relator's vote, which the ata cites but does not reproduce and which we have not located; 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.

What we refuse to claim: we do not say how any councillor reasoned or voted beyond the ata's statement that the Plenary decided unanimously, and 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.
