Brasilia closed both of Brazil's open AI files in 48 hours. They point opposite ways.

This desk has been carrying two open Brazilian items. On July 9 the watch list called publication of a Redata timeline the switch that turns pending Brazilian data center requests into siting decisions. On August 20 it asked whether PL 2780/2024 would finally receive a formal despacho to a named committee, the critical minerals bill having sat at AGUARDANDO DESPACHO since arriving from the Camara on May 8.

Both closed inside 48 hours. Not with a despacho and not with a timeline, but with floor votes and a trip to the presidential desk.

What’s happening

• The Senate approved PL 278/26, creating Redata, the Regime Especial de Tributacao para Servicos de Datacenter, on the night of Tuesday September 1. Rapporteur Cid Gomes (PSB/CE) took four drafting amendments and rejected roughly 30 others. It can now go to presidential sanction [agencia eixos, September 1, 2026].
• Redata zeroes federal taxes on imported electronic and IT components destined for data centers. Revenue forgone can reach R$5.2 billion this year and R$1 billion in each of the two following years, R$7.2 billion on the published schedule [agencia eixos, September 1, 2026].
• The counterparts are specific: renewable or low emission generation for the entire electricity demand, a water efficiency index at or below 0.05 litre per kWh on an annual cooling average, investment inside Brazil worth 2 percent of tax-benefited purchases, and 10 percent of data center services reserved for the domestic market [agencia eixos, September 1, 2026].
• Drafting amendment number 5, from Laercio Oliveira (PP/SE), swapped “clean” sources for “low emission” ones. The wording change is small and the effect is not: it widens the eligible supply to take in natural gas, which is how agencia eixos headlined the vote. The Camara’s Secretaria da Mesa told Senate president Davi Alcolumbre the change altered the merit of a text the deputies approved on February 25, which would have forced the bill back. It was processed as drafting anyway [agencia eixos, September 1, 2026].
• One day later, on Wednesday September 2, the Senate approved PL 2780/2024 by symbolic vote, instituting the Politica Nacional de Minerais Criticos e Estrategicos and the Conselho Nacional para Industrializacao de Minerais Criticos e Estrategicos, or CIMCE. Rapporteur Eduardo Braga (MDB/AM) held the Camara text intact. It also goes to sanction [agencia eixos and Radio Senado, September 2, 2026].
• The minerals side carries a Fundo Garantidor da Atividade Mineral capped at R$2 billion from the federal budget plus a share of sector gross operating revenue, and fiscal credits on the order of R$5 billion across five years for domestic processing by companies incorporated under Brazilian law [Radio Senado, September 2, 2026]. Prior habilitation by CIMCE unlocks a credit of up to 20 percent on processing carried out on national territory [Poder360, September 3, 2026].

Brazil angle

CIMCE is the part that matters, and it is not a study group. If the bill is sanctioned the council will sit directly under the Presidency of the Republic. It evaluates and homologates operations of strategic relevance, defined to include transfer of corporate control, the sharing of geological information, and the signing of international ties involving critical and strategic minerals. In practice it can block international supply contracts and partnerships, block the sale, cession or encumbrance of mineral titles granted by the Union, and refuse data access to foreign companies or governments [Poder360, September 3, 2026].

The composition tells you the intent. Up to 15 federal Executive representatives against two from the private sector, plus subnational and academic seats. Amendments that tried to rebalance that were rejected [agencia eixos, September 2, 2026]. Braga told the floor the council “will do nothing more than homologate the contracts,” except that now Brazil is not giving up national sovereignty.

Two guardrails went in. A Tereza Cristina (PP/MS) amendment bars the council from accumulating functions that sit with the ANM, leaving the agency with regulation, oversight and title granting [agencia eixos, September 2, 2026]. At the Camara stage, Arnaldo Jardim (Cidadania/SP) accepted amendments replacing “prior consent” with “homologation,” a concession to a sector warning about legal insecurity [Poder360, September 3, 2026]. The senators kept that text whole.

US angle

The industry is not reassured by the softer verb. Frederico Bedran, who heads the Associacao de Minerais Criticos, calls the council a “legal anomaly” that cannot sit above the regulator. In an interview given to Poder360 in late July, well before this vote, he argued the measure brings legal insecurity to a sector whose investment is majority foreign, and asked the question every foreign acquirer will now ask: how do you invest in a mining project without knowing whether it will be homologated. IBRAM president Pablo Cesario expects only a “small fraction” of transactions to be reviewed, restricted to supply security and sovereignty cases, and says the institute will push for changes during regulation [Poder360, September 3, 2026].

Both readings can be right, and that is the problem. The instrument exists and its aperture is undefined. It lands on a claim map already heavily foreign: when AP and Reporter Brasil reviewed every ANM rare earth application through June, 42 percent came from foreign-linked filers and the US accounted for 347 [AP and Reporter Brasil, as reported by this desk, August 20, 2026]. Those positions were taken when a change of control was a commercial matter. It is now a homologation.

China angle

The clause that bites hardest is not the one about equity. It is the power to refuse geological data access to foreign governments and companies and to block international supply agreements. China has filed no ANM rare earth applications at all [AP and Reporter Brasil, as reported by this desk, August 20, 2026]. Beijing’s route into Brazilian critical minerals was never the claim register. It was contracts and processing partnerships, exactly what CIMCE now homologates.

What it means

Brazil has spent this year being described as the diversification case. This week it priced both halves of that trade inside 48 hours, and the two prices are close. R$7.2 billion of forgone revenue across three years to import the compute, against a R$2 billion guarantee fund cap plus roughly R$5 billion of processing credits across five years to keep the minerals chain onshore, about R$7 billion (desk arithmetic on the two published schedules; the horizons differ, three years against five, so read this as order of magnitude rather than a like for like ratio). Brasilia will pay comparable money to host the data centers and to refuse to be only the quarry underneath them.

Neither is law yet. Both await Lula’s signature and both then need regulation. Redata’s regulation has to define what “low emission” means, which is where the natural gas question actually gets settled. CIMCE’s regulation has 90 days from sanction and has to define what an operation of strategic relevance is [agencia eixos, September 1, 2026; Poder360, September 3, 2026]. The statutes are the easy part.

Against the desk indexes as of August 29, SOV50 stood at 122.2 with a basket HHI of 0.66, against SDX at 103.6 and TAI at 108.4. Concentration is repricing faster than diversification is arriving. A jurisdiction that legislates a veto over its own diversification supply is not an obvious way to close that gap.

What to watch

• Whether Lula sanctions both texts without vetoes, and specifically whether drafting amendment 5 on “low emission” survives. The Camara’s Secretaria da Mesa already put on record that it altered merit, which is a live vector for a partial veto or a later challenge.
• The CIMCE regulation inside 90 days of sanction. The number to find is the threshold defining an operation of strategic relevance. Cesario’s “small fraction” and Bedran’s “legal anomaly” describe the same law until that threshold is written.
• The first control transfer submitted to CIMCE, and how long homologation takes. One Australian or American acquisition of a Brazilian rare earth position, timed end to end, will tell foreign capital more than the statute does.
