Wire House (Wirehouse)

A “wire house” (or “wirehouse”) is a brokerage house that has a communication network; originally, a “wire house” meant a brokerage house with a telegraph line or a telephone line. Later, a “wire house” meant a big firm that had electronic (and often wireless) communications. The term “wire house” is still used today, even though technology has made the term dated.
 
“Wire house” is cited in print from at least 1894. According to a 1922 source (below), the first “wire house” used a telegraph wire from Wall Street to 23rd Street in Manhattan in 1873.

wire house Finance Definition
A brokerage house whose offices are linked by a communication network to enable prices, information, orders and research to be distributed to all the offices. The term is relatively out of date now, but before computers became widely used, only the largest firms had access to the state-of-the-art equipment that interconnected their offices. As used today, wire house generally means one of the biggest brokerage firms.

wire house
national or international brokerage firm whose branch offices are linked by a communications system that permits the rapid dissemination of prices, information, and research relating to financial markets and individual securities. Although smaller retail and regional brokers currently have access to similar data, the designation of a firm as a wire house dates back to the time when only the largest organizations had access to high-speed communications. Therefore, wire house still is used to refer to the biggest brokerage houses.

What is a Wire House?
When you have a bank account, you can typically use any branch of your bank to make deposits, withdrawals or otherwise. The reason you’re able to do this is because all of the branches belonging to your bank, through computer communication, are essentially “wired” together and have access to the same information though high-speed communication means. This can also be called a wire house.
 
In the example above, wire house doesn’t refer to the branch itself, but to the company (house), which organizes its many locations by providing them with the same level of access to information. Those old enough to remember the pre-computer era of banking realize the term is still a relatively new one. Prior to the ability to communicate via computer from bank to bank, no company could be called a wire house. If you wanted instant access to your funds, you’d visit the bank that was your home branch, since it had direct information about your bank balance.
 
When computers were first developed, they were massive machines not intended for home use. High-speed connections between different parts of a company or different branches of the same bank were common in businesses long before they were affordable for use at home. Only the biggest companies could afford the expense of being able to provide communication from office to office, and frequently these companies were brokerage firms. It thus became common to refer to a large brokerage firm as a wire house, as they were wired together so that the same information was available to every aspect of the firm.
 
The name stuck, even though we now see examples of “wired” companies in a variety of settings and it’s as common as air. You can visit or call a stockbroker at any location and receive current and the latest information on prices of stocks and drops in the market. You can even direct a broker to purchase or sell stock, which can often be done immediately, and you’re able to get this information online too.

The Work of the Stock Exchange
By James Edward Meeker
New York, NY: The Ronald Press Company
1922
Pg. 324:
But with the steady westward thrust of population and wealth into our southern and western states, the demand for stock market facilities has led to a similar extension of the Stock Exchange system into all parts of the nation, through the rise of the “wire house” type of Stock Exchange commission firm. The first sign of this coming development was shown in 1873, when a prominent Wall Street firm established a private telegraph line to its up-town office at 23rd Street—a great convenience at a time before the elevated railroador telephone system, when it took over an hour to communicate between the two offices. The obvious advantages of such (Pg. 325—ed.) speedy means of communication soon bore more extensive results. In 1879 private wires were obtained by various Wall Street firms to their offices in the neighboring centers of Boston and Philadelphia.
