The whole day fits into one question of ownership: who owns the surface where the brand appears. OpenAI is testing an ad with a chat button that opens a brand conversation inside ChatGPT, and the landing page stops being the destination — the middle of the funnel becomes rented space. Sharpie put a pen in an NFL rookie’s hand without buying a league or a team sponsorship. A Belgian party borrowed IKEA’s typeface for an immigration plan, and the CJEU spent the entire ruling listing the conditions under which that is legal. Ben Cohen took the Brandweek stage to hand out a brief asking for a guerrilla campaign against the owner of the brand he founded. And Caloi dug up a slogan from 1980 — the only asset of the day that depends on no counterparty at all.
Counterparty, in fact, is what ties the second half together. The Ben & Jerry’s agreement gives an independent board legal authority over mission, marketing and use of the brand, and Magnum simply doesn’t show up to the meetings: a governance clause with no enforcement mechanism is worth whatever the other side wants it to be worth. On the same day, the Brazilian energy market shows up building exactly the mechanism that’s missing — daily collateral, registered derivatives, clearing house. The difference between the two stories isn’t legal, it’s infrastructural. And it’s the same difference that separates the publisher who went to Miami to discuss an AI licensing contract in the dark from the one that, like yesterday’s Atlantic, already traded visits for subscribers.
product and growth
Sharpie at the NFL draft — The Rookie of the Year program is in its third year and drove 3.6 million clicks in year two, against 471,000 in year one (+428%), with reach doubling (+102%), according to the brand. The decision that matters isn’t the campaign, it’s the refusal: Sharpie is not an official sponsor of the league or of any team, it buys individual athletes — and only the draft’s top 9, because, in the words of CMO Nick Hammitt, the story loses its legs if you go after a fourth or fifth rounder. What makes the pen–football association work without a license is the ritual that was already there: the rookie signs the contract with a Sharpie. Buying the ritual costs a fraction of buying the category.
Muse, Meta’s personal agent, in Claire Vo’s hands — A review episode of real usage: onboarding, calendar management, goals, buying through the browser. From the walkthrough, two product points are worth more than the rest: the activity feed that shows the lineage of the task, tool call by tool call, which she says she wants in Codex and Claude Code, and the permission model, which she describes as unlike any agent she’s tested. Browser use did badly buying sneakers and well buying an IMAX ticket — which is the honest cut of the category today: a task with a closed form works, a task with judgment doesn’t.

IKEA against a political campaign at the CJEU (C‑298/23) — The court held that freedom of expression can indeed be “due cause” for using a mark with a reputation, but that invoking it isn’t enough: the defendant has to show the concrete grounds and why they outweigh the owner’s right. The practical detail for anyone registering a trademark is in the list of factors the CJEU pre-chewed for the Belgian court: “IKEA” has no linguistic meaning of its own, hasn’t become a cultural reference or common language, the use wasn’t feeding a debate about IKEA, and the font, the color and the styling were deliberately the brand’s. In other words, the invented name, expensive to build from scratch, pays off here — a brand that has become an everyday word has far less protection against appropriation. The court also confirmed that art. 10(6) of the directive, optional and implemented in Belgium, requires neither use in the course of trade nor use for goods and services.
Ben Cohen’s public brief — At Brandweek, the Ben & Jerry’s founder handed the audience a brief: guerrilla campaign, maximum budget of $20k (“cheaper is better”), execution in the US or in Amsterdam, where Magnum is based, deadline of October 7, 2026, prize of ice cream for life if the brand regains its independence. The backstory is the case study: sold to Unilever in 2000 with an independent board that kept legal authority over social mission, quality, marketing and use of the brand, while the buyer kept finances and operations; after the spin-off to Magnum at the end of 2025, the CEO was replaced, Jerry Greenfield left and the foundation shuts down by year’s end. The petition has 200,000 signatures and the campaign about 800,000 followers — which, in practice, is the only enforcement instrument left from the contract. My read: whoever sells a company believing in a mission clause is buying a reputational asset, not an enforceable right.
Caloi revives “Não Esqueça Minha Caloi” — Four decades later, the concept returns with the addressee flipped: “Não Esqueça a Caloi do Seu Filho”. The original slogan spoke to the kid asking for the bike; the new one speaks to the adult who was that kid and today signs the credit card slip. It’s the cheapest form of brand equity there is — not building memory, collecting interest on the memory that’s already there. The run, between September and November, goes from Meta and YouTube to GNT, Multishow, GloboNews, SporTV, Globoplay Novelas and Telecine, with creative by D’om Soluções Improváveis.
media and attention
four fronts of AI advertising in five days — OpenAI is piloting Sponsored Agents, ads with a “Chat with us” button that open a brand conversation inside ChatGPT, with Wayfair testing at limited scale. Google is running an “AI contribution” pilot in Search Console that pays the publisher when the content meaningfully feeds AI Mode, AI Overviews or Gemini — dozens of sites, mostly small and mid-sized, and the company tried to keep the program secret; in parallel, it’s testing text link ads in AI Mode, with a single “Sponsored” label above the entire answer. Microsoft published the manual for the other side: an ad with synthetic creative needs disclosure, preserved watermark and provenance metadata, and stripping the metadata fails the asset. Three of these fronts are fighting over the middle of the funnel, the fourth is about provenance — and the most telling footnote is ChatGPT entering at #5 in Brand Keys’ loyalty ranking, ahead of Netflix and Coca-Cola.
the Digiday Publishing Summit in its “Google Zero” edition — The lede (the piece is behind a subscriber wall) says the Miami town halls revolved around three things: falling search traffic, opaque AI licensing contracts and how to monetize visibility inside AI. It’s worth less for what it reports and more for how it fits: it’s the same mechanism as the item above seen from below, by the side that loses the click and still doesn’t know what it’s selling is worth.
market and capital
Brazilian energy discovers collateral and clearing — After the wave of trading firms filing for bankruptcy protection, BBCE is working with Bradesco to offer trading with collateral calculated and collected daily, like a margin call, with launch expected for early 2027 and optional in nature, only on shorter contracts. The stock of derivatives registered on the platform rose 300% in twelve months and hit R$10bn at the end of August, most of it in non-standardized contracts. N5X, created by EEX with L4 Venture Builder (a fund with capital from B3), is seeking Banco Central authorization to set up a clearing house and an electricity exchange, aiming at the second half of 2027 — and this is the second time this week that B3 shows up financing a trading venue that isn’t its own. Meanwhile, Trafigura made its electricity debut in Brazil to fill the vacuum left by those who exited: a confidence crisis is the window in which guarantee infrastructure finally gets through.
Singapore as counter-evidence to “the end of the card” — A Nuvei study projects the credit card going from 56% of local e-commerce in 2024 to 57% in 2028, with bank transfer (pulled by PayNow) going from 8% to 9% and debit falling from 21% to 18%. The instant rail didn’t eat credit because it doesn’t do the same thing: installments, rewards and access to credit are not settlement. In Brazil, Visa Conecta puts Pix at 45% of the last online purchase against 47% for credit, and Pix Parcelado pushes in the same direction. The conflict-of-interest caveat is obvious — Nuvei sells checkout and concludes that a variety of payment methods is a conversion lever — but the share series in Singapore is verifiable and contradicts the substitution thesis that dominates the payments conversation here.
the week’s quant roundup — Two links on the list are worth it for their stated method. One tests Fama‑French factors inside the S&P 500 with walk-forward from 2006 to 2025 and starts from a premise that’s rarely said out loud: the academic long-short, the fund restricted to large caps and the investor with thirty equal-weighted names are treated as if they were the same trade, and they aren’t. The other runs 437,911 strategy configurations across nine instruments, 160 walk-forward windows and 26.5 billion permutations to answer whether in-strategy Monte Carlo permutation testing improves forward-looking selection — the answer is no. For anyone building a data product, the second is the useful item: a standard validation step, expensive in compute, that doesn’t deliver what it promises.
stalled sources
First Round Review has gone 325 days without publishing, Gurwinder 263, Calculated Risk 249, Elad Gil 150 and the Y Combinator blog 93. Anti-Mimetic (64), Adjacent Possible (39), Kyla Scanlon (35), Collab Fund and Sherwood News (31), Granted (20) and Snaxshot (15) round out the list. The bigger hole is still VC editorial content — the category that used to write the most about building product is the one writing the least now.
