When you buy a stock, your money almost always goes to another investor: the person or fund on the other side of your trade, not the company whose name is on the shares. The only time your cash actually reaches the company’s bank account is when you buy newly issued shares in an initial public offering or a follow-on offering. Every other purchase happens on the secondary market, where shares change hands between investors and the company itself receives nothing. Small amounts also go to regulatory fees and to the firms that execute and settle the trade, and when you eventually sell, the IRS takes a cut of any gain.
Your Money Goes to the Seller on the Other Side
Buy 50 shares of a listed company on the NYSE or Nasdaq today, and you’re buying them from someone who already owned them and decided to sell. Your cash, minus a few tiny fees, lands in that seller’s brokerage account. The company’s cash balance doesn’t move at all.
The seller could be another retail investor, a pension fund rebalancing its portfolio, a hedge fund exiting a position, or a mutual fund raising cash to meet redemptions. You don’t know who they are and it doesn’t matter. The price you pay is the lowest asking price available at the moment your order executes. Place a market order for $10,000 of stock and roughly $10,000 flows to whoever was on the other side.
This secondary market is what makes stocks worth owning at all. Without a ready buyer whenever you want to sell, shares would be closer to a locked vault than an investment. That liquidity is also why investors are willing to fund companies at the moment of a new issuance in the first place.
When Your Money Actually Reaches the Company
A company receives cash from stock sales only when it issues brand-new shares. That happens in two situations. In an initial public offering, a private company sells shares to the public for the first time. In a follow-on offering, a company that’s already public creates and sells additional shares. Federal law prohibits selling unregistered securities to the public, so the company files a registration statement with the SEC before the shares can trade.1Office of the Law Revision Counsel. 15 USC 77e – Prohibitions Relating to Interstate Commerce and the Mails The filing includes a prospectus with audited financials, business and risk descriptions, information about management, and how the company intends to spend the proceeds.
The company doesn’t keep every dollar. Investment banks that underwrite the offering collect fees typically running about 4% to 7% of proceeds, with legal and accounting costs on top. What’s left flows into the corporate treasury and funds whatever the prospectus described: building factories, hiring, paying down debt, or acquisitions. This is the only scenario where buying stock is a direct investment in the company’s operations.
Who Else Takes a Slice of the Trade
Most major brokerages stopped charging per-trade commissions years ago, which raises the obvious question of who’s paying to execute your order. For many firms, the answer is the market maker that fills it. Under an arrangement called payment for order flow, your brokerage routes your order to a market-making firm, and that firm pays the brokerage for the right to handle it. The market maker profits by buying slightly lower than it sells, capturing the spread across millions of trades. SEC rules require brokerages to disclose these arrangements in quarterly reports, including the dollar amounts received from each venue.2eCFR. 17 CFR 242.606 – Disclosure of Order Routing Information
Whether this helps or hurts individual investors is genuinely debated. Brokerages and market makers argue that retail customers get better prices than they would on an exchange. Critics, including some at the SEC, argue the setup creates conflicts of interest because brokerages have reason to route orders to whoever pays the most rather than whoever offers the best execution. The SEC proposed a rule in 2022 that would have required more competitive auction processes for retail orders; it hasn’t been finalized. Payment for order flow is legal in the United States, though the EU has moved to phase it out by mid-2026.
Two small regulatory fees are baked into every trade. You usually won’t see them broken out on a brokerage app, but they’re there.
- SEC Section 31 fee, which funds the SEC’s operations. The rate adjusts annually and sits at $20.60 per million dollars in covered securities sales for fiscal year 2026. On a $10,000 sale, that’s about two cents. The fee applies only when you sell.3U.S. Securities and Exchange Commission. 2026 Annual Adjustments to Transaction Fee Rates
- FINRA Trading Activity Fee, which funds FINRA’s oversight of broker-dealers. For 2026, the rate is $0.000195 per share on covered equity sales, capped at $9.79 per trade. Selling 100 shares costs less than two cents.4FINRA. Section 1 – Member Regulatory Fees
These are trivial for individual investors, fractions of a penny per share on a typical trade. Across trillions of dollars in annual trading volume, they add up to enough revenue to fund the agencies that police the markets.
How the Money and Shares Actually Move
Execution and settlement are two different moments. When your order fills, the exchange confirms a match between buyer and seller. The actual exchange of cash for shares happens on a cycle called T+1, one business day after the trade date.5U.S. Securities and Exchange Commission. Shortening the Securities Transaction Settlement Cycle The SEC shortened this from two business days in May 2024.6U.S. Securities and Exchange Commission. Frequently Asked Questions Regarding the Transition to a T+1 Standard Settlement Cycle
During that one-day window, a DTCC subsidiary called the National Securities Clearing Corporation steps in as the middleman and guarantees that the trade will complete even if one side fails to deliver.7DTCC. NSCC – National Securities Clearing Corporation Rather than settling every trade individually, NSCC nets millions of transactions against each other. If a brokerage’s clients collectively bought $500 million and sold $480 million of a particular stock on a given day, only the $20 million difference actually moves. That netting sharply reduces how much cash and stock physically changes hands.
Another DTCC subsidiary, the Depository Trust Company, handles the ownership side. Virtually all publicly traded shares exist as electronic entries in DTC’s system rather than as paper certificates.8DTCC. The Depository Trust Company – DTC When your trade settles, DTC updates its books to reflect the new ownership.
After settlement, your shares almost certainly aren’t registered in your name. They’re held in “street name,” meaning they’re registered to your brokerage’s nominee account at DTC, and your brokerage keeps internal records showing how many shares within that pool belong to you. That’s why you can sell instantly through an app rather than mailing paperwork. You still receive dividends and can vote through proxy materials your broker forwards. Direct registration, where shares are recorded in your name on the company’s books through its transfer agent, is available if you want it, but takes a few business days to arrange in either direction.
Buying Isn’t Taxed. Selling Is.
The purchase itself triggers no federal tax. The tax event comes when you sell, and the difference between what you paid and what you received is a capital gain or loss. Shares held for one year or less generate short-term capital gains, taxed at ordinary income rates that can reach 37%. Shares held for more than one year qualify for long-term capital gains rates, which top out at 20% and drop to 0% for lower-income filers.
Your brokerage reports the sale to you and the IRS on Form 1099-B, including proceeds, cost basis, buy and sell dates, and whether the gain is short-term or long-term.9Internal Revenue Service. Instructions for Form 1099-B If you sell at a loss, watch the wash sale rule: repurchasing the same stock within 30 days before or after the sale disallows the loss deduction for that year.10Office of the Law Revision Counsel. 26 USC 1091 – Loss From Wash Sales of Stock or Securities The disallowed loss gets added to the cost basis of the replacement shares, so it isn’t gone forever, just deferred.
What SIPC Does and Doesn’t Cover
While your cash sits in a brokerage account or your shares are held in street name, the Securities Investor Protection Corporation provides a backstop if the brokerage itself fails. Coverage tops out at $500,000 per customer, with a $250,000 sublimit for uninvested cash.11SIPC. What SIPC Protects Many brokerages carry additional private insurance on top.
SIPC coverage is narrower than most people think. It applies when your brokerage goes bankrupt and your assets are missing from your account. It does not cover losses from a stock’s price falling, from bad advice, or from fraud by the company whose stock you bought. If your shares lose half their value because earnings collapsed, that’s your loss to bear. SIPC only steps in when the broker-dealer is the problem.
Uninvested cash in your brokerage account is typically swept into a bank deposit program or money market fund, which can add FDIC coverage on the cash portion. Rates on these sweep accounts vary widely, and the default option is often the one that pays the least, so it’s worth checking your brokerage’s specific program.
