Slim family discloses 6.5% stake in Braskem

The move

Carlos Slim's family and two of his foundations disclosed in a Nov. 6 SEC filing that they jointly hold about 22.4 million Class A shares of Brazilian petrochemical maker Braskem, held as ADSs, equal to roughly 6.5% of the company's outstanding Class A shares. Control Empresarial de Capitales holds 1.5%, Fundacion Carlos Slim holds 4.0% and Fundacion Telmex holds 1.0%; the three entities spent a combined roughly $17.4 million buying the shares. The filing says the family bought the stake for investment, not to seek control, but that it may contact Braskem's management or board about capitalization, board composition or operations.

Why it matters

A new stake from one of the world's richest investors is a vote of confidence in a company that has struggled with weak petrochemical prices and liabilities tied to a ground-subsidence disaster in Brazil.

The bear case

A 6.5% stake described as "for investment purposes" gives the Slim family no board seat or control, and the filing itself says they may just as easily sell the shares depending on market conditions.

What to watch

Whether the Slim family's stake grows past levels that would require further disclosure.

Carlos Slim entities disclose 6.5% stake in Braskem

The move

Entities linked to Carlos Slim Helu, including Control Empresarial de Capitales and two family foundations, disclosed combined ownership of about 6.5% of Braskem's Class A shares in a Schedule 13D filed Nov. 6 with the SEC. The filing says the shares were bought for investment purposes and that the group does not intend to seek control of the company.

Why it matters

Braskem, the Brazilian petrochemical maker, has spent 2026 restructuring more than $11 billion in debt, and its Mexican joint venture Braskem Idesa filed for Chapter 11 protection in August. Slim's camp is already a creditor in that restructuring, so a fresh equity stake adds to his exposure to how it plays out.

The bear case

A 6.5% stake with no board seats and an explicit "no control" statement gives Slim little direct say over a restructuring that creditors have already pushed back on once.

What to watch

Whether Braskem's parent reaches a deal with bondholders on its debt restructuring.

Carlos Slim Helu & familyDivestitureEnergyTALOAI read · ▼ Trimming into an oil-stock rally

Carlos Slim keeps selling Talos Energy stock

The move

Control Empresarial de Capitales, Carlos Slim's family holding company, sold 1,508,586 shares of Talos Energy (TALO) on Oct. 27 and Oct. 28 at weighted-average prices of $18.50 and $18.33, an SEC Form 4 shows, leaving it with 20,491,414 shares.

Why it matters

Slim's investment vehicle has trimmed its Talos stake several times in 2026 as oil-linked stocks have rallied this year.

The bear case

Slim remains one of Talos's largest shareholders even after the sales, so this looks like profit-taking rather than an exit.

What to watch

Further Form 4 filings from Control Empresarial de Capitales if oil prices keep climbing.

Carlos Slim sells down his Talos Energy stake again

The move

Carlos Slim's investment arm, Control Empresarial de Capitales, sold about 4 million more shares of Talos Energy between October 23 and October 28, worth roughly $73.5 million combined, according to SEC filings. The sales cut its holding to about 20.5 million shares, extending a trim that began earlier in October.

Why it matters

The filings don't state a reason, but Control Empresarial has been selectively paring the position while staying near the ownership levels set out in its cooperation agreement with Talos.

The bear case

Control Empresarial still held about 24% of Talos as of mid-2026 and bought shares of Talos and PBF Energy earlier this year, so the October sales look more like trimming a large position than exiting it.

What to watch

Whether Control Empresarial's stake approaches the 25% cap set in its cooperation agreement with Talos.

Carlos Slim Helu & familyInsider tradeEnergyTALOAI read · ▼ Trimming down

Carlos Slim's firm sells $86 million of Talos Energy

The move

Control Empresarial de Capitales, Carlos Slim's holding company, sold about 4.9 million shares of Talos Energy between Oct 15 and Oct 19 for roughly $85.9 million combined, according to SEC filings. The sales cut its stake to 24.5 million shares, or 14.7% of the oil and gas company, from about 29.4 million shares.

Why it matters

Slim's firm has been a major Talos shareholder for years; a steady reduction can signal he is reallocating away from the stock.

The bear case

The filings don't say why the sales happened, and Slim's firm still owns a large, double-digit stake in the company.

What to watch

Future SEC filings from Control Empresarial de Capitales for further changes to its Talos Energy stake.

Carlos Slim Helu & familyInsider tradeEnergyTALO · PBFAI read · ▼ Selling

Carlos Slim's firm sells $122M in US energy stocks

The move

Control Empresarial de Capitales, Carlos Slim's holding company, sold 6.24 million shares of Talos Energy for about $106.8 million and 170,000 shares of PBF Energy for about $15 million, in trades made Oct 8-12, 2026, according to SEC Form 4 filings signed Oct 13 by Marco Antonio Slim Domit. The firm still held about 32.4 million Talos shares and 13.3 million PBF Class A shares afterward.

Why it matters

The sales trim two of the Slim family's independent bets on US offshore drilling and refining, even though the remaining stakes are still large.

The bear case

Selling roughly 16% of the Talos stake and a small slice of PBF isn't an exit — the family remains among each company's largest shareholders.

What to watch

Whether further SEC filings show the selling continuing.

Carlos Slim Helu & familyAcquisitionMediaAMXAI read · ▲ Bullish

Slim's América Móvil closes Brazilian ISP deal

The move

América Móvil, controlled by Carlos Slim, closed its purchase of 72.83% of Brazilian internet provider Desktop on Oct. 1 through its Claro NXT Telecomunicações unit, acquiring 84.7 million shares for about 1.75 billion reals ($334.3 million), or roughly $3.95 per share. Desktop serves more than 1.2 million subscribers across over 200 Brazilian cities. América Móvil shares rose after the deal was reported.

Why it matters

It's a small but concrete expansion of Slim's Latin American telecom footprint into Brazilian broadband, a market América Móvil has been building out through its Claro brand.

The bear case

The deal is tiny next to América Móvil's roughly $49 billion in annual revenue, so it won't move the company's overall numbers much on its own.

What to watch

Whether América Móvil folds Desktop into Claro's broader Brazilian broadband push or keeps it as a standalone brand.

Carlos Slim Helu & familyPropertyReal estatePrivateAI read · — Redevelopment bet

Slim commits $200 million to rebuild historic Puebla district

The move

Carlos Slim's Grupo Carso announced a 4 billion peso (roughly $200 million) investment to redevelop the Paseo San Francisco area near Puebla's historic center, including about 700 apartments, two levels of retail, underground parking and new public plazas, with construction over about two years. The plan already has 1.5 billion pesos committed to land purchases and is expected to create 1,500 direct and 2,500 indirect jobs, with hiring priority for people living in the area.

Why it matters

It echoes Slim's redevelopment of Mexico City's historic center in the early 2000s and signals a continued bet on Mexican urban real estate.

The bear case

Large redevelopment projects near historic districts can displace existing small businesses and residents despite stated plans to prioritize locals for jobs.

What to watch

Permitting and groundbreaking progress over the next two years.
