Sullivan & Cromwell LLP is a prominent American multinational law firm based in New York City. Established in 1879 by Algernon Sydney Sullivan and William Nelson Cromwell, the firm has played a significant role in shaping corporate and financial legal frameworks in the United States, particularly in areas such as shareholder derivative suits, antitrust legislation, federal income taxation, and securities registration. It provided counsel on landmark deals including the creation of U.S. Steel and Edison General Electric, maintaining a robust footprint both within the U.S. and abroad.

Among its notable transactions was Ford Motor Company's $643 million securities offering in 1956. Over time, the firm adapted by launching dedicated divisions for banking law and mergers and acquisitions to meet evolving market demands.

On the international front, Sullivan & Cromwell has a long history, from financing major U.S. infrastructure projects to advising the Panama Canal Authority. It was one of the earliest American firms to open offices overseas, though its past includes contentious roles such as involvement with Nazi Germany’s armament expansion and participation in the 1954 Guatemalan coup d'état.

The firm has been embroiled in controversies including insider trading allegations, representation of tobacco industry clients, and criticism linked to its involvement in the FTX cryptocurrency collapse. In 2024, it contracted a background screening company to assess candidates connected to pro-Palestinian organizations, scrutinizing demonstrators irrespective of their language use. In 2025, Sullivan & Cromwell became engaged in legal proceedings related to the second Trump administration’s efforts targeting law firms and is representing President Donald Trump in his appeal against his criminal conviction in New York State courts.

History

Founded in 1879 by Algernon Sydney Sullivan and William Nelson Cromwell, Sullivan & Cromwell played an advisory role to John Pierpont Morgan during the establishment of Edison General Electric in 1882 and later assisted key figures in founding U.S. Steel in 1901. Cromwell was instrumental in developing the holding company concept by lobbying New Jersey lawmakers to incorporate it into state legislation, which allowed corporations to circumvent antitrust laws. The firm also innovated corporate restructuring through what became known as the "Cromwell plan," earning Cromwell the moniker "the physician of Wall Street" for his efforts in rehabilitating distressed companies.

Following World War I, Sullivan & Cromwell expanded its finance practice, structuring numerous equity and debt instruments—including 94 loan agreements extended to European borrowers over seven years. The firm’s business grew significantly during the 1930s as it represented clients facing increased regulatory scrutiny, becoming one of the largest law firms globally. During the Great Depression, it engaged in litigation involving emerging legal areas such as shareholder derivative actions, antitrust enforcement, federal income tax matters, and securities registration. Notably, it filed the first substantial registration statement under the Securities Act of 1933 and helped shape tax regulations affecting the mutual fund sector.

In 1956, Sullivan & Cromwell managed legal aspects of Ford Motor Company's $643 million securities offering—the largest at that time. Responding to shifting commercial landscapes, it launched a banking law practice in 1968 and created a dedicated mergers and acquisitions team by 1980 as M&A activity intensified. By the mid-1980s, mergers and acquisitions contributed approximately one-third of the firm's total revenue.

Global operations

Sullivan & Cromwell's engagement in international matters dates back to its early support of European financiers involved in U.S. industrial and transportation projects. By the early twentieth century, the firm was representing French stakeholders in Panama and played a role in funding the Panama Canal; it still acts on behalf of the Panama Canal Authority today.

The firm was a pioneer among American law firms in opening offices abroad, initiating this expansion with a Paris branch in 1911, followed by locations in Buenos Aires and Berlin by 1928. In 1935, partner Allen Dulles advocated ceasing business activities in Nazi Germany, resulting in the closure of the Berlin and Frankfurt offices—although this was officially recorded as occurring in 1934. During John Foster Dulles' tenure, the firm had supported Germany’s military armament efforts by incorporating IG Farben into a global nickel cartel alongside American, Canadian, and French companies.

Two former chairmen of Sullivan & Cromwell held significant foreign policy positions under President Eisenhower: John Foster Dulles served as U.S. Secretary of State, while Arthur Dean played a key role in negotiating the Korean Armistice Agreement.

From a financial perspective, Sullivan & Cromwell ranks among the most lucrative law firms worldwide, with profits per partner surpassing $6 million and profits per lawyer exceeding $1.3 million in 2021.

IG Farben and Nazi Germany

During Foster Dulles’s leadership, the firm facilitated Nazi Germany’s military expansion by incorporating the German chemical conglomerate I.G. Farben into an international nickel cartel that included firms from the United States, Canada, and France. By the 1940s, I.G. Farben was notorious for exploiting forced labor from concentration camps, including approximately 30,000 prisoners at Auschwitz, where it also conducted medical experiments on detainees at Auschwitz and Mauthausen. One of its subsidiaries, BASF, produced the poison gas Zyklon B, which was used in Holocaust gas chambers responsible for over one million deaths. I.G. Farben maintained substantial control over Degesch, the company manufacturing Zyklon B, with its board members holding critical administrative positions.

Following World War II, U.S. authorities confiscated I.G. Farben’s assets, and 23 executives were prosecuted for war crimes; 13 were convicted.

1954 coup in Guatemala

Sullivan & Cromwell played a documented part in the 1954 overthrow of Guatemala’s government by representing the United Fruit Company (UFC), which had significant business interests there. UFC utilized its lobbying influence through the firm and other avenues to sway President Eisenhower and Secretary of State John Foster Dulles—both former partners at Sullivan & Cromwell—as well as CIA director Allen Dulles, facilitating the removal of Guatemala’s democratically elected President Jacobo Arbenz.

Insider trading scandal

In 2008, authorities uncovered an insider trading scheme involving ex-Sullivan & Cromwell attorney Gil Cornblum and an accomplice, both lawyers who had attended law school together. They exploited confidential information obtained from Sullivan & Cromwell and Dorsey & Whitney to generate illicit profits exceeding $10 million over a span of 14 years. Cornblum took his own life during the investigation shortly before he could be arrested or charged; his partner later entered a guilty plea.

Tobacco companies

Sullivan & Cromwell has provided legal counsel to tobacco industry clients, including its advisory role in the 2008 merger between Altria and the U.S. Tobacco Company.

FTX

The firm encountered scrutiny for its involvement with FTX, a cryptocurrency exchange that collapsed amid allegations of fraud. Sullivan & Cromwell undertook substantial advisory work for FTX prior to its bankruptcy. In January 2023, concerns about a potential conflict of interest were raised by four U.S. Senators due to the firm's deep engagement before the insolvency proceedings.

Legal scholars Jonathan Lipson and David Skeel contend that as FTX approached bankruptcy, Sullivan & Cromwell advised then-CEO Sam Bankman-Fried to transfer control to John J. Ray III under deceptive conditions and neglected to address possible criminal liabilities for Bankman-Fried and others. While facilitating this transition, the firm also alerted federal authorities to issues at FTX, prompting ethical questions.

Lipson and Skeel further criticize Sullivan & Cromwell for not initiating malpractice actions against other law firms involved before bankruptcy or pursuing any measures against Binance, whose withdrawal activity precipitated FTX’s liquidity crisis.

During the pre-bankruptcy phase, both Sullivan & Cromwell and Fenwick & West employed auto-deleting messaging systems when communicating with FTX staff. Although a U.S. Bankruptcy Examiner initially cleared the firm, Sullivan & Cromwell remains under investigation regarding its advice to Bankman-Fried on acquiring part of Robinhood Markets and whether it should have detected FTX’s fraudulent activities during that representation.

Pro-Palestinian protestors

In 2024, Sullivan & Cromwell attracted criticism for investigating students associated with pro-Palestinian organizations by engaging a background screening company to analyze social media content and protest recordings. Individuals were scrutinized even if they did not use inflammatory language themselves but participated in demonstrations where others did. Yale professor Roderick A. Ferguson warned this method risks unjustly attributing collective responsibility to individual participants.

Representation of Donald J. Trump

In January 2025, Sullivan & Cromwell represented Donald J. Trump in appealing his conviction on 34 felony charges connected to hush money payments made prior to the 2016 election. The firm became the first prominent law office to defend Trump in a criminal case, a decision noted for its significant reputational implications given Trump's divisive public image.

Co-chair Robert Giuffra took part in discussions with Paul, Weiss regarding Trump's broader campaign targeting law firms representing his adversaries. Giuffra played a key role in negotiating an agreement whereby Paul, Weiss conceded several of Trump's demands.

Awards and Recognition

In January 2025, Sullivan & Cromwell earned the distinction of Law360 Firm of the Year and secured eight Practice Group of the Year honors spanning Banking, Bankruptcy, Fintech, Insurance, Product Liability, Tax, Transportation, and White Collar sectors.
