Quando IA, dados, interface e automações não conversam, sobra para o usuário juntar as partes.

Por isso, na OpenMarkets, esse fluxo nasceu integrado. Você consulta os dados e faz novas perguntas ao Analista enquanto aprofunda a leitura nas ferramentas.

Depois, pode automatizar o que quer acompanhar. A análise fica mais fluida. A decisão continua com você.

Veja esse fluxo em ação na demo. Este conteúdo não constitui recomendação de investimento.

A assinatura do Claude/GPT não é o único custo de analisar empresas com IA. A cada análise, você precisa fornecer ou buscar dados e documentos, remontar contexto e prompt. Na OpenMarkets, já comece direto pela pergunta. Todo o resto já está estruturado. https://t.co/lsPWd7mZrm

[Leonardo Mazzaferro @mazzaferroleo]

Quanto mais empresas você acompanha, mais difícil é manter a profundidade das análises.

A OpenMarkets ajuda a ampliar a sua cobertura com dados oficiais da B3/CVM, contexto e rastreabilidade.

Menos trabalho manual. Mais tempo para a tomada de decisão.

🦔Microsoft canceled its internal Claude Code licenses this week after token-based billing made the cost untenable, even for a company with effectively infinite cloud resources. Uber's CTO sent an internal memo warning the company burned through its entire 2026 AI budget in just four months. American AI software prices have jumped 20% to 37%, and GitHub (owned by Microsoft) is dropping flat-rate plans for usage-based billing across its products.

My Take
The AI subsidy era is ending in real time. The same company that put $13 billion into OpenAI and built the Azure infrastructure powering most of Anthropic's compute just looked at the bill from a competitor's coding tool and decided it was not worth paying. That is not a productivity failure on Anthropic's end. Token-based pricing is forcing every enterprise customer to confront the actual cost of running these models at scale, and the number turns out to be far higher than the flat-rate experiments suggested.

This ties directly to my Gemini Flash post yesterday. Anthropic, OpenAI, and Google all raised effective prices in the last six months. Enterprises that built workflows assuming AI costs would keep falling are now watching annual budgets evaporate in months. Two outcomes look likely from here. Either enterprises scale back AI usage to fit budgets, which slows the revenue ramp the labs need to justify their valuations ahead of IPOs, or the labs cut prices and absorb the losses, which makes the unit economics worse at exactly the wrong moment. Both paths land in the same place, the numbers stop working, and somebody has to take the writedown.

Second order effects. Fertilizer plants are closing in India because they lack LNG.

India is the world second largest sugar producer.

🌽HOLY. CORN. BUYING.

Money managers in the week ended March 10 bought more than 140,000 CBOT corn futures & options contracts (the fourth most for any week on record).

The resulting net long - 193,271 contracts - isn't even halfway to the all-time record (429k in 2010).

Let me clarify because we have a lot of new people.. (and I was a little clickbaity)
Effectively, IN CHINA they are paying ¥680 for the April DELIVERED oil contract.
Brent ($80) + freight ($15) + misc expenses gets you there.
Want someone to blame? blame tanker people

Alphabet is going to be spending more than the capex of:

ExxonMobil, Chevron, BP, Shell, TotalEnergies, Equinor, Eni, Antero Resources, APA Corporation, ConocoPhillips, Expand Energy, Continental Resources, Coterra Energy, Devon Energy, EOG Resources, EQT Corporation, Diamondback Energy, Occidental Petroleum, Range Resources, Permian Resources, Imperial Oil, Cenovus Energy, Canadian Natural Resources, Ovintiv, Suncor Energy, Tourmaline Oil

COMBINED!

Let that sink in.

Ethanol is still trading at a firm 2.1c premium over sugar in Brazil, reinforcing a stronger financial incentive for mills to favor ethanol production (over sugar) this year. The last time Brazil experienced a similar ethanol premium over sugar, the sugar mix was much lower, at ~46%.

[Stephen Geldart @StephenGeldart]

How slow is sugar hedging from cane mills in Centre-South Brazil at the moment?

This slow. The stronger BRL isn't helping right now either.
