Initial Public Offering (IPO)

An initial public offering (IPO) is the first sale of a private company’s shares to public investors on a stock exchange. It turns a private business into a publicly traded one, raising fresh capital in exchange for outside ownership and public scrutiny.

IPOs let founders and early backers cash out, fund expansion, or acquire rivals with newly issued paper. In return, the company accepts SEC-grade disclosure, quarterly earnings pressure, and a share price that swings with sentiment.

Global IPO activity has cooled sharply since the 2021 boom. In 2024, companies raised roughly $121.2 billion across 1,215 listings worldwide — a modest lift on 2023 but still less than half the 2021 peak, according to EY’s Global IPO Trends report.

The top end has since reopened — EY counted 12 US deals raising more than US$1 billion in the first half of 2026, against four in the same period a year earlier.

Key takeaways

• An IPO turns private equity into publicly traded shares on exchanges like NYSE or Nasdaq.
• Companies use IPOs to raise cash, repay debt, fund acquisitions, or reward early investors.
• Underwriters, regulators, and roadshows set the price and buyer base weeks before the first trade.
• 2024 saw 1,215 IPOs raise about $121.2 billion globally, per EY: below 2021’s peak but above 2023.
• Post-IPO life brings quarterly earnings duty, SEC filings, and constant share-price scrutiny.

How it works

An IPO happens in stages. The company hires underwriters, files an S-1 registration with the SEC, markets shares on a roadshow, agrees a price the night before listing, then trades on an exchange the next morning. Most deals run six to twelve months.

The typical sequence looks like this:

1. Selection of underwriters: the issuer picks lead banks such as Goldman Sachs or Morgan Stanley.
2. Due diligence and drafting: lawyers and accountants prepare the S-1 registration statement.
3. SEC filing and review: the S-1 goes public; regulators send comment letters and demand revisions.
4. Roadshow: executives pitch institutional investors across New York, Boston, London, and Hong Kong.
5. Pricing: underwriters and the issuer agree the final share price after building the order book.
6. Listing day: shares trade on the NYSE or Nasdaq under a fresh ticker.

Here is roughly how those steps fit on a calendar:

Listing day is the loud part. But most of the value creation and risk transfer happens weeks earlier during the roadshow, when large venture capital funds and asset managers place indications of interest — the numbers that shape the final book.

Underwriters also stabilise the stock in the days after listing using a 15% over-allotment option, often called a green shoe. If demand runs hot, they exercise it and sell extra shares.

If the price sags, they buy back stock to prop it up during the first 30 days.

Companies typically pay 4% to 7% of gross proceeds in underwriter fees, plus legal, accounting, and listing costs that can push total spend past $10 million on a mid-sized deal, per PwC’s cost of an IPO analysis.

That toll is why many founders now weigh direct listings or SPAC mergers as cheaper alternatives.

Examples

Three recent listings show the range of IPO outcomes: Arm Holdings’ 2023 Nasdaq return raised $4.87 billion, Reddit’s 2024 NYSE debut popped 48% on day one, and Manila-based outsourcer TaskUs closed 24% above its 2021 offer price in its first session.

• Arm Holdings (2023): the British chip designer, owned by SoftBank, sold 95.5 million American depositary shares at $51 on 14 September 2023, generating $4.87 billion, as Reuters reported at the time.
• Reddit (2024): the social platform priced its NYSE IPO at $34 on 21 March 2024, valuing the company at about $6.4 billion; shares closed 48% higher on debut.
• TaskUs (2021): the business process outsourcing firm, headquartered in New Braunfels and Manila, listed on Nasdaq at $23 on 11 June 2021, closing that first session at $28.60.
• Klaviyo (2023): the Boston marketing-automation vendor priced at $30 on the NYSE on 20 September 2023, ending its first session at $32.76 for a $9.2 billion valuation.

TaskUs is the clearest outsourcing-sector reference point. TaskUs’s Manila-based delivery footprint, built on Philippine call-centre operations, gave it the margin structure institutional buyers wanted heading into listing.

Its post-IPO share price has swung with the wider tech cycle, a reminder that a strong first day rarely guarantees a smooth first year.

Related terms

IPO sits inside a cluster of capital-markets ideas. The list below connects it to the funding rounds that precede a listing and the mechanics that surround the offer itself.

• Venture capital: the private funding round most companies pass through before an IPO becomes viable.
• Private equity: pre-IPO firms often sit inside PE portfolios waiting for an exit window.
• Return on investment (ROI): early backers judge IPO success by ROI on their entry-round shares.
• Capital expenditure: IPO proceeds often fund CapEx that debt markets won’t cover.
• Direct listing: an alternative that floats existing shares without underwriter bookbuilding.
• Business process outsourcing (BPO): many post-IPO firms outsource back-office work to fund growth without inflating headcount.

FAQ

What’s the difference between an IPO and a direct listing?

An IPO issues brand-new shares and raises capital through an underwriter-run bookbuild. A direct listing floats existing shares only, skipping underwriters and dilution but sacrificing the price certainty a bookbuild provides.

How long does the IPO process take?

Six to twelve months for most companies. The SEC review of the S-1 alone typically runs three to four months, and roadshows add another one to two weeks before pricing kicks off.

Can retail investors buy shares before the IPO price?

Rarely at scale. Underwriters allocate most pre-IPO shares to institutions. Retail brokers like Robinhood and SoFi offer small allocations through IPO access programmes, but demand usually outstrips supply.

What does ‘lock-up period’ mean?

It is a contractual restriction — usually 180 days after listing — that stops insiders, employees, and pre-IPO investors from selling shares. When it expires, sudden supply can push the stock price down sharply.

Do all IPOs rise on day one?

No. Around two-thirds price above their offer in first-day trading, but the median 2024 IPO ended its first year below the offer price, according to Renaissance Capital.
