Companies make money from stocks by creating new shares and selling them, and only then. That cash comes in through an initial public offering, a follow-on offering after the company is already public, or a private placement to a select group of investors. Once shares are trading between investors on an exchange, those trades no longer touch the company’s bank account. The line between the primary market (company sells new shares, company gets paid) and the secondary market (investors trade with each other) is the whole answer to how equity actually funds a business.
The First Sale: How an IPO Puts Cash on the Balance Sheet
An initial public offering is the moment a private company first creates shares, registers them with the Securities and Exchange Commission, and sells them to outside investors. The proceeds go straight to the company. Management can then spend that money on expanding operations, funding research and development, or paying down debt. Nothing about the transaction requires repayment. That is the core difference between raising equity and taking a loan.
To get there, the company files a registration statement (Form S-1) disclosing its financials, business model, and risk factors, and hires one or more investment banks as underwriters. The underwriters price the shares, market them to institutional and retail buyers, and guarantee the company a set amount of proceeds. Underwriting fees have sat around 7% of proceeds for decades on moderate-sized IPOs, dropping to roughly 4–5% on deals above $1 billion. So on a $500 million IPO, tens of millions of dollars go to the banks before the company sees the rest.
Selling More Shares After Going Public
Being public doesn’t cap how much equity a company can sell. A company already trading on an exchange can issue more shares whenever it wants to raise more money. These transactions go by several names: follow-on offerings, secondary offerings, or seasoned equity offerings. The mechanics are the same each time. The company creates new shares, sells them, and keeps the cash. If instead an existing large shareholder sells their own holdings, that money goes to the shareholder, not the company. The label matters.
Follow-on offerings must be registered with the SEC, and the company pays a registration fee based on the dollar value of shares being sold. For fiscal year 2026, that fee is $138.10 per million dollars of securities registered.1U.S. Securities and Exchange Commission. Filing Fee Rate The company files a prospectus supplement describing the terms and how it plans to use the proceeds.
Existing shareholders pay close attention. Each new share issued shrinks their percentage ownership, reduces earnings per share, and dilutes their voting power. To keep the same stake, they have to buy enough of the new shares themselves.
At-the-Market Offerings
Rather than dump a large block of stock in one day, a company can sell shares gradually at whatever the trading price happens to be. The company registers a shelf of shares under SEC Rule 415 and then has a broker-dealer dribble small batches into the open market over time.2eCFR. 17 CFR 230.415 – Delayed or Continuous Offering and Sale of Securities Because the sales are spread out, they tend to move the stock price less than a single large offering. Management can also wait for favorable prices without locking in a fixed sale date.
Rights Offerings
A rights offering hands existing shareholders the first chance to buy the new shares, usually at a 15% to 30% discount to the market price. Each shareholder gets rights proportional to their current holdings and typically two to four weeks to exercise them, sell them, or let them expire. Anyone who participates keeps their ownership percentage intact. The company still raises the money.
Selling Shares Privately Instead
Companies do not need public markets to raise equity. Under Regulation D of the Securities Act, a company can sell shares privately to a limited pool of investors and skip full SEC registration. Rule 506 offers two exemptions, and there is no cap on how much can be raised under either.3Investor.gov. Rule 506 of Regulation D
Under Rule 506(b), the company cannot advertise the offering publicly. It may sell to an unlimited number of accredited investors and up to 35 non-accredited investors who are financially sophisticated enough to evaluate the risks. Under Rule 506(c), the company can advertise broadly, but every buyer must be accredited, and the company has to take reasonable steps to verify that status rather than accept a self-certification.
An individual qualifies as an accredited investor with a net worth above $1 million (excluding the primary residence), or income above $200,000 individually, or $300,000 combined with a spouse or partner, in each of the prior two years, with a reasonable expectation of the same in the current year.4U.S. Securities and Exchange Commission. Accredited Investors Private placements are common among startups and growth-stage companies that need cash but aren’t ready for the expense of a public offering.
Two Alternatives to a Traditional IPO
The traditional underwritten IPO is not the only route to public markets, and the two main alternatives handle the cash question differently.
In a direct listing, a company’s existing shares simply start trading on an exchange without underwriters or a roadshow. The opening price is set by supply and demand in the exchange’s auction. A standard direct listing raises no new capital for the company. It only lets existing shareholders (employees, early investors) sell to the public. The NYSE and Nasdaq now allow “primary direct floor listings,” in which the company can also sell newly issued shares during the opening auction and receive fresh capital, similar to an IPO but without paying underwriters.
A SPAC is a shell company that raises cash through its own IPO with no operating business. The money sits in a trust while the SPAC’s managers search for a private company to acquire, usually within two years. When they find one, the SPAC merges with it in a transaction called a de-SPAC, and the private company becomes public. SPAC shareholders can generally redeem their shares for their portion of the trust rather than staying invested in the merged company.5Investor.gov. What You Need to Know About SPACs – Updated Investor Bulletin For the private company on the other side, the merger delivers both a public listing and a pool of capital.
Using Stock Instead of Cash
A company can also spend its stock instead of selling it. Two situations account for most of this: acquisitions and employee compensation. In both, the company preserves cash it would otherwise have to spend.
In a stock-for-stock acquisition, the buyer issues new shares to the target company’s owners as payment. A merger agreement typically sets a fixed exchange ratio, so target shareholders might receive 0.5 shares of the acquirer for every share they hold. The buyer grows its asset base and market share without draining its bank account. The strategy works best when the acquirer’s stock price is high, because each share issued “buys” more of the target’s value.
Stock-based compensation works on similar logic. Companies grant restricted stock units or stock options to employees, executives, and directors, keeping cash on the balance sheet for operations and growth. This is especially common at technology firms and startups where cash is scarce but equity has upside. Accounting rules still require the company to recognize the fair value of those grants as compensation expense, even though no cash moves.6U.S. Securities and Exchange Commission. Codification of Staff Accounting Bulletins – Topic 14: Share-Based Payment Equity plans have to be disclosed in the annual proxy statement so shareholders can see how much stock is being handed to insiders.7U.S. Securities and Exchange Commission. Annual Meetings and Proxy Requirements
One quiet advantage of any of these issuances: the corporation owes no tax on the money or property it receives in exchange for its own stock, including treasury shares it previously repurchased.8Office of the Law Revision Counsel. 26 USC 1032 – Exchange of Stock for Property Whether the raise is $10 million or $500 million, none of it counts as taxable income.
Why Daily Trading Doesn’t Pay the Company
Once shares are out in the market, buying and selling them is a transaction between investors. Millions of shares might change hands on any given day, but the cash flows from one investor’s account to another. When you buy shares of a public company on the NYSE or Nasdaq, your money goes to whoever sold you those shares. The company received its money once, at the point of issuance: the IPO, the follow-on, or the private placement. Everything after that is other people trading its paper.
The trading price still matters to the company, just indirectly. A higher share price makes any future equity offering more valuable, because the company has to issue fewer shares to raise a given dollar amount. It strengthens the company’s hand in stock-for-stock acquisitions and makes equity compensation more attractive to employees and recruits. A falling price does the reverse. Raising capital becomes more dilutive, deals get harder to close on favorable terms, and stock grants lose some of their pull. So a public company watches its share price closely, but not because the trades themselves generate revenue. They don’t.
