Whether you are researching Berkshire Hathaway Inc. on its own, evaluating Marvell Technology, Inc., or weighing the two companies side by side, the breakdown below highlights where each company leads and where the gap between Berkshire Hathaway Inc. and Marvell Technology, Inc. is widest.

On the headline numbers, Berkshire Hathaway Inc. reports annual revenue of $371.4B against $8.2B for Marvell Technology, Inc., while their respective market capitalizations stand at $1.07T and $225.7B. Both Berkshire Hathaway Inc. and Marvell Technology, Inc. are headquartered in United States, so they compete in a shared home market and regulatory environment.

Berkshire Hathaway Inc.: Berkshire Hathaway does not make a single product under its own name. It owns insurers (GEICO, General Re, National Indemnity, Alleghany), the BNSF railroad, Berkshire Hathaway Energy's regulated utilities and pipelines, manufacturers such as Precision Castparts, Lubrizol, Marmon and OxyChem, distributors such as McLane and Pilot, and consumer businesses such as See's Candies and Dairy Queen. On top of that sits an equity portfolio worth $297.8 billion at the end of 2025, whose five largest positions, American Express, Apple, Bank of America, Coca-Cola and Chevron, accounted for 65% of its value. About 387,800 people worked for Berkshire's businesses at the end of 2025, roughly 80% of them in the United States.

Marvell Technology, Inc.: Marvell Technology, Inc. is a Santa Clara-based fabless chip designer focused on data infrastructure. Its products sit between processors rather than replacing them: optical DSPs that link GPUs and switches, Ethernet switch chips, storage and security processors, and custom accelerators built with cloud customers. Matt Murphy has been CEO since 2016 and also serves as chairman. The company had about 7,400 employees at January 31, 2026 and a market value of roughly $226 billion in late September 2026.

Berkshire Hathaway Inc. and Marvell Technology, Inc. pursue distinct approaches to generating revenue, and understanding how each company operates is the foundation of any fair comparison between Berkshire Hathaway Inc. and Marvell Technology, Inc..

Berkshire Hathaway Inc. business model: Berkshire's business model is capital allocation on top of a decentralized group of operating companies. Subsidiary managers run their own businesses, with no corporate budget submissions and no committee structure at headquarters, and send surplus cash to Omaha. The chief executive then decides where it goes: into existing operations, new acquisitions such as the $9.7 billion purchase of OxyChem completed in January 2026, marketable equities, or Berkshire stock when it trades below estimated intrinsic value. Insurance is the core. Policyholder money held before claims are paid, which Berkshire calls float, reached $176 billion at the end of 2025, and the group has earned a pre-tax underwriting profit in each of the three years to 2025, so that float has cost less than nothing. Berkshire has not paid a dividend since 1967, which is why retained earnings and float, rather than outside capital, fund almost everything it buys.

Marvell Technology, Inc. business model: Marvell runs a fabless model: it designs chips and licenses-in or builds IP (SerDes, PAM4 and coherent DSPs, Arm compute subsystems, packaging), while foundries such as TSMC manufacture them. It makes money in two ways. First, it sells standard products, including electro-optics DSPs and drivers for optical modules, Teralynx Ethernet switches, PCIe/CXL retimers, storage controllers and OCTEON processors. Second, its custom business co-designs AI accelerators and other ASICs for hyperscalers, earning engineering fees during development and product revenue once chips ship in volume. Marvell reports revenue as Data Center (74% of fiscal 2026) and Communications and Other (26%), which covers enterprise networking, carrier infrastructure and consumer products. In fiscal 2026, 57% of revenue came from direct customers and 43% through distributors.

The durability of a company's moat often decides long-term winners. Here is how the competitive advantages of Berkshire Hathaway Inc. stack up against those of Marvell Technology, Inc..

Berkshire Hathaway Inc. competitive advantage: Berkshire's advantages are permanent capital, a balance sheet that stays liquid by design, and a reputation that brings sellers to it. It held $369.0 billion of cash, cash equivalents and Treasury Bills in its insurance and other businesses at the end of 2025 and carries limited debt, which is why it could supply capital to Goldman Sachs, General Electric and other companies during the 2008 crisis on terms no one else was offering. Owners of private businesses who care where their companies end up sell to Berkshire for the same reason: Bell Laboratories came to Berkshire in 2025 because its chief executive wrote to Buffett on behalf of the founder's daughters. Subsidiary managers also keep real autonomy, with no corporate budgets to submit and no quarterly earnings pressure.

Marvell Technology, Inc. competitive advantage: Marvell's edge is breadth of data-center IP. It combines high-speed SerDes, PAM4 and coherent optical DSPs (largely from the 2021 Inphi deal), Ethernet switching, custom ASIC design services and, since 2026, Celestial AI's photonic interconnect technology. That lets it sell several components into the same AI cluster and offer hyperscalers a full custom-chip design and packaging service on advanced TSMC nodes. Nvidia's 2026 NVLink Fusion partnership also lets Marvell custom silicon connect to Nvidia-based systems.

Future prospects matter as much as current results. The growth strategies below explain how Berkshire Hathaway Inc. and Marvell Technology, Inc. each plan to expand from here.

Berkshire Hathaway Inc. growth strategy: Berkshire's size limits what can move its results, so growth comes from large purchases, reinvestment inside existing businesses and buying back its own stock. Buffett described the 2009 BNSF agreement, a $34 billion investment in the railroad, as an all-in wager on the economic future of the United States. The 2025 and 2026 examples are smaller: a $9.7 billion purchase of Occidental's chemicals business, OxyChem, and the family-owned pest-control manufacturer Bell Laboratories. Abel has said Berkshire will buy productive businesses in preference to holding Treasuries, but will not stretch on price, which is why cash and Treasury holdings still exceeded $370 billion at the end of 2025 and no shares were repurchased that year. Berkshire also adds to listed holdings when prices suit it, paying $16.9 billion for equity securities during 2025.

Marvell Technology, Inc. growth strategy: Marvell's growth plan centers on AI infrastructure. It is expanding custom XPU and XPU-attach programs with large cloud providers, upgrading optical DSPs from 800G to 1.6T and beyond, growing Teralynx switches and retimers, and adding optical scale-up interconnect through Celestial AI. It has narrowed its portfolio to fund this, selling the automotive Ethernet business to Infineon in 2025, and it widened its reach in 2026 through Nvidia's NVLink Fusion ecosystem.

A closer look at the financial trajectory of Berkshire Hathaway Inc. and Marvell Technology, Inc. rounds out the comparison.

Berkshire Hathaway Inc.: Berkshire reported 2025 revenue of $371.444 billion, operating earnings of $44.486 billion (down from $47.437 billion in 2024 and above the five-year average of about $37.5 billion), and net earnings attributable to shareholders of $66.968 billion. GAAP net earnings swing with the equity portfolio: 2025 included $30.737 billion of after-tax investment gains and $8.255 billion of after-tax impairments on Kraft Heinz and Occidental. The businesses produced $46 billion of net cash from operating activities. Insurance earned $9.460 billion of pre-tax underwriting profit, with GEICO contributing $6.824 billion, and insurance float grew to $176 billion from $171 billion a year earlier.

Marvell Technology, Inc.: Marvell's revenue was $2.70 billion in fiscal 2020 and $5.77 billion in fiscal 2025, then jumped 42% to $8.195 billion in fiscal 2026 as AI data-center demand ramped. GAAP results were losses from fiscal 2021 through fiscal 2025, mainly due to amortization from the Inphi and Cavium deals and restructuring charges. Fiscal 2026 GAAP net income was $2.67 billion, helped by a pre-tax gain of about $1.8 billion on the $2.5 billion sale of the automotive Ethernet unit to Infineon. In Q2 fiscal 2027 (quarter ended August 1, 2026) revenue was $2.739 billion, GAAP net income $308.0 million ($0.33 per share), non-GAAP EPS $0.94 and operating cash flow $605.5 million. Marvell guided Q3 fiscal 2027 revenue to $3.15 billion, plus or minus 5%.
