Apple's next foldable iPhone will reportedly use a screen made almost entirely by Samsung — one of Apple's most direct competitors in the smartphone market. That's not an isolated oddity. It's the normal way Samsung does business, across an almost absurd range of industries that has no real parallel anywhere else in the corporate world.
Samsung Group is not, in any meaningful sense, one company. It's a chaebol — a South Korean term for a family-controlled network of dozens of legally separate businesses operating under one brand and one controlling family. Samsung is the largest of these in the country, spanning more than 60 affiliated companies, and its footprint reads less like a technology company's balance sheet and more like a list of industries a normal conglomerate would never touch simultaneously: semiconductors, pharmaceuticals manufacturing, construction, shipbuilding, oil refining, advertising, insurance, and theme parks, all under a single controlling ownership structure.

Here's the full picture, starting with the story making headlines right now.
Samsung is reportedly building the screen for Apple's first foldable iPhone
Samsung Display has reportedly signed a three-year exclusive deal to supply OLED panels for Apple's first foldable iPhone, expected to launch in 2026. Samsung is expected to ship around 3 million panels in 2026 to support Apple's initial production run, with manufacturing beginning in the second quarter of the year. (AppleInsider)
The reason isn't sentiment — it's that Apple reportedly doesn't have another real option. BOE, the Chinese display maker that supplies some flat-panel iPhone screens, is considered inadequate for foldable production at Apple's quality bar, and LG Display, Apple's other major supplier, doesn't yet manufacture folding smartphone screens at all. That leaves Samsung Display as effectively the only supplier capable of delivering foldable OLED technology at the volume and quality Apple needs — reportedly using Color Filter on Encapsulation (CoE) technology, which removes polarizer layers and integrates color filtering directly into the panel's encapsulation, reducing light loss and improving brightness. (MacRumors)
So Apple's most ambitious new hardware category in years will reportedly launch running on a screen supplied entirely by Samsung — the same company that makes the Galaxy Z Fold, Apple's most direct foldable-phone competitor.
Samsung also makes chips for half of Silicon Valley's biggest names
This pattern isn't limited to displays. Samsung's semiconductor foundry business — the division that manufactures chips designed by other companies — counts an unusually direct list of competitors and rivals as paying customers: Tesla, Nvidia, Qualcomm, Apple, AMD, and Google have all placed foundry orders with Samsung. (TechSpot)
The Tesla relationship alone is enormous: Samsung signed a $16.5 billion deal to fabricate Tesla's next-generation self-driving chips, a contract running through 2033. Samsung also manufactures Nvidia's custom Tegra T239 processor — the chip powering the Nintendo Switch 2 — and has secured contracts to build AMD's future Epyc server processors on its next-generation 2nm manufacturing node. As of 2026, demand has grown enough that Samsung has been raising its advanced foundry prices by up to 15%, driven by AI-related chip demand overflowing from Samsung's larger rival, TSMC. (TweakTown)
That's the Apple-and-TSMC half of Samsung's identity: a company that both designs and sells its own competing consumer electronics, while simultaneously manufacturing critical components for the companies it competes against.
Samsung manufactured hundreds of millions of doses of Moderna's COVID vaccine
In May 2021, Moderna signed a manufacturing agreement with Samsung Biologics — a separate Samsung affiliate focused entirely on pharmaceutical contract manufacturing — to handle large-scale fill-finish production of its COVID-19 vaccine, mRNA-1273. Technology transfer began immediately at Samsung Biologics' Incheon, South Korea facility, and the company reduced the typical production timeline enough to release its first vaccine batch for domestic supply within five months of signing the contract. (Samsung Biologics)
South Korea's own drug regulator authorized the Samsung-manufactured version of Moderna's vaccine, and additional emergency-use authorizations followed in the Philippines and Colombia. A company whose global brand is built around smartphones and TVs was, simultaneously, one of the manufacturing backbones of the world's pandemic vaccine supply chain.
Samsung built the world's tallest building
Samsung C&T Corporation — Samsung's construction and trading arm — was the primary contractor behind the Burj Khalifa, the 828-meter tower in Dubai that remains the tallest building on Earth. Samsung C&T led the project in a joint venture with Belgium's BESIX and the UAE's Arabtec, holding a 55% share of the work, versus 30% for BESIX and 15% for Arabtec. Construction ran roughly six years, from January 2004 to the building's January 2010 inauguration, at a total cost of around $1.5 billion. (Construction Placements)
Samsung C&T won the contract partly on the strength of an even earlier record: the company had previously built the Petronas Towers in Kuala Lumpur, which held the title of the world's tallest building from 1998 until the Burj Khalifa surpassed it in 2004. Two of history's most iconic skyscrapers, built by the same company that makes your phone.
Samsung runs one of the world's largest shipyards
Samsung Heavy Industries, founded in 1974, holds the world's largest market share in three of the most technically demanding vessel categories in shipbuilding: drillships, LNG carriers, and FPSO (Floating Production, Storage and Offloading) vessels. Its Geoje shipyard carries the largest single-yard order backlog in the world, at roughly 9% of the entire global shipbuilding orderbook. In cumulative 2024 order volume, Samsung Heavy Industries ranked second globally, behind only fellow South Korean shipbuilder HD Hyundai Heavy Industries. (Manufacturing Digital)
Samsung builds oil refineries and petrochemical plants for state oil giants
Samsung E&A (formerly Samsung Engineering) has operated in the refinery construction business since 1994, building grass-roots refineries, aromatics plants, heavy-oil upgrading facilities, and clean-fuel plants around the world. Its client list includes some of the most significant state-owned energy companies on Earth: Saudi Aramco, the UAE's ADNOC, and Algeria's Sonatrach. (Samsung E&A)
Samsung is a major EV battery supplier — including to Apple's car-industry counterparts
Samsung SDI builds electric vehicle batteries at genuinely massive scale. In 2026, the division signed a multi-year battery supply agreement with Mercedes-Benz worth more than 10 trillion won — roughly $6.8 billion. Samsung SDI has also supplied BMW since 2009, and is currently collaborating with BMW and US-based Solid Power on validating next-generation all-solid-state EV batteries. A joint venture with Stellantis built battery manufacturing capacity in Indiana, though Stellantis has more recently reconsidered parts of that US investment amid broader EV demand slowdowns and reported losses exceeding €22 billion.

Samsung runs South Korea's largest advertising agency
Cheil Worldwide, Samsung's in-house marketing and communications arm, is South Korea's largest advertising agency, operating 29 networks across 25 countries from its Seoul headquarters. WARC has ranked Cheil the No. 1 global creative network originating from Asia, and in the 2026 Agency Report rankings of the world's largest agency holding companies, Cheil placed No. 12 globally — a genuinely significant position for an agency built inside a hardware and semiconductor conglomerate rather than a dedicated marketing holding company.

Samsung owns South Korea's biggest theme park
Opened in 1976, Everland, located in Yongin, Gyeonggi Province, is South Korea's largest theme park and draws roughly 6.6 million visitors a year. It's operated directly by Samsung Group, making the company that manufactures memory chips and cargo ships also the operator of the country's most-visited amusement park.
What Samsung is actually building right now
Beyond its existing sprawl, Samsung is in the middle of the single largest semiconductor investment any company has ever made in one year. In 2026, Samsung committed more than 110 trillion won — roughly $74 billion — toward AI chip production, expanded R&D, and its Taylor, Texas foundry, a 128% increase over its 2025 semiconductor capital spending. The Taylor facility is targeting mass production in 2027, with preparations for a second Taylor fab already underway ahead of a planned groundbreaking. (Sammy Fans)
On the memory side, Samsung's HBM4 chips — high-bandwidth memory built specifically for AI workloads — are now in mass production at speeds of 11.7 gigabits per second, ahead of the prior 8GB industry standard, with HBM4E and HBM5 already in parallel development. In October 2025, Samsung and fellow Korean chipmaker SK Hynix signed a letter of intent with OpenAI to eventually supply 900,000 DRAM wafers a month — a scale of commitment that reflects just how central Samsung's memory business has become to the broader AI buildout, not just to phones and laptops.

How one company legally does all of this
The mechanism holding this entire structure together is the chaebol ownership model itself. Samsung is controlled by South Korea's Lee family through a web of cross-shareholdings running primarily between Samsung C&T Corporation, Samsung Life Insurance, and Samsung Electronics — a structure that lets the family maintain effective control over dozens of legally independent, separately traded companies without owning a straightforward majority stake in any single one of them. Lee Jae-yong, grandson of Samsung's founder, currently leads the group. (Seoulz)
That cross-shareholding structure is precisely why Samsung can operate a foundry serving Apple and Tesla, a pharmaceutical manufacturer serving Moderna, a construction arm serving Dubai's government, and a theme park serving Korean families — all as separately incorporated entities that share a name, a founding family, and enough interlocking ownership to move in strategic coordination when it matters.
The bottom line
No single Western analogy captures what Samsung actually is, which is exactly the point of comparing it to five completely different companies at once. It's Apple's screen supplier and one of its most direct hardware competitors. It's a foundry serving TSMC's own biggest customers. It's a pharmaceutical manufacturer that helped produce a global vaccine supply. It built the two tallest buildings the world has ever had, at two different points in history. It's one of the largest shipbuilders and refinery contractors on Earth, a top-15 global advertising network, and the operator of a theme park drawing millions of visitors a year. Somewhere underneath all of it sits a single family's cross-shareholding structure, holding together what might be the most genuinely diversified corporate empire currently operating anywhere in the world.
