Confusion between IPOs and everyday stock trading is one of the most common beginner mix-ups. The IPO is the primary offering moment; the secondary market is where most investors actually buy and sell afterwards. This US-focused explainer separates the two.
The primary market
In a typical IPO, a company registers securities with the SEC and sells new shares (and sometimes secondary shares from existing holders) to investors through underwriters. The offering price is set through a book-building process. Shares are allocated — often largely to institutions — and then listed for trading.
The secondary market
Once listed, shares trade between investors on exchanges such as the NYSE or Nasdaq. The company does not receive money when you buy shares from another investor in the secondary market (except in specific follow-on contexts). Prices fluctuate with supply and demand.
Why IPO day feels different
Media attention, first-day price pops or drops, and lock-up calendars create drama. Education tip: a strong first day does not guarantee long-term results; a weak first day does not automatically mean failure. Read the prospectus guide.
Follow-on offerings
Companies may sell additional shares later (seasoned equity offerings). Those are also primary issuances in spirit — capital raising — but they occur after the company is already public.
ETFs are not IPOs
Buying an ETF on the open market is secondary-market trading in fund shares. Creation/redemption with authorised participants is a separate institutional mechanism. See ETF basics.
Primary = company (or sellers) issuing shares; secondary = investors trading among themselves.
Allocation reality for retail
Many brokerages run IPO centres with eligibility rules, conditional offers, and limited share counts. Receiving an allocation is not assured. Education sites that imply easy IPO access for everyone are overselling. Stock Meerkat will not pretend otherwise.
Price discovery after listing
The first days and weeks of trading are a discovery process. Underwriters’ stabilisation activities, lock-up calendars, and shifting sentiment all appear in market commentary. None of those mechanics guarantees profit.
How to study an IPO without FOMO
- Read the prospectus risk factors and financials.
- Note who is selling — company, early investors, or both.
- Separate media narrative from filings.
- If you lack allotment access, secondary-market patience is still a choice — and still risky.
Practical takeaway
If your brokerage screen shows a buy button on a listed ticker, you are almost always participating in the secondary market. That is normal — and it is where order-type literacy matters. Delayed quotes on Stock Meerkat are secondary-market orientation tools only.
Quiet period reminders
Communications rules around offerings exist to protect the integrity of disclosure. If you are studying an IPO as a learner, prefer filed documents over rumour threads. Stock Meerkat will not amplify unverified allocation tips.
