An IPO (Initial Public Offering) is the first time a company sells shares to the public. For investors, it's a chance to get in at the "ground floor" — sometimes leading to spectacular gains, sometimes to painful losses. This guide explains the IPO process in Poland and globally, how to subscribe, and what to watch out for.
Who this guide is for
- You want to understand how companies go public and whether to participate.
- You've heard about Allegro, Dino, or XTB IPOs on WSE and want to know the mechanics.
- You're considering IPOs on NYSE/NASDAQ through IBKR or other brokers.
After reading you'll be able to: read a prospectus, subscribe to a Polish IPO via your broker, assess underwriting risks (underpricing, overpricing, lock-up), and decide whether an IPO fits your portfolio.
What happens in an IPO
An IPO transforms a private company into a public one. The company sells newly issued shares (and sometimes existing shareholders sell too) on a regulated exchange. Typical steps:
- Company decides to go public — needs capital, wants liquidity for founders.
- Hires investment bank(s) as underwriter(s) — e.g., PKO BP, mBank, Goldman Sachs.
- Due diligence + prospectus — legal and financial disclosure document (sometimes 300+ pages).
- Regulator approval — KNF in Poland, SEC in the US.
- Roadshow — management pitches to institutional investors.
- Price range + bookbuilding — demand is collected, final price set.
- Allocation — shares distributed to subscribers.
- First trading day — shares listed on exchange.
Prospectus — your most important document
The prospectus (prospekt emisyjny) is a legal document disclosing:
- Business model, revenue streams, competitors.
- 3 years of audited financial statements.
- Risk factors (sometimes 50+ pages!).
- Use of proceeds (what the company will do with the money).
- Management team and their compensation.
- Shareholders and planned sales (including lock-up agreements).
Golden rule: read at minimum the risk factors section. If you don't understand the business after skimming the prospectus — pass on the IPO.
Bookbuilding vs fixed price — PL vs global
Polish IPO — "księga popytu"
Most WSE IPOs use bookbuilding:
- Price range announced (e.g., 38–43 PLN per share).
- Investors submit declarations of how many shares at what price they'd buy.
- Issuer sets final price based on demand.
- Allocation (often retail gets fewer shares than declared).
US IPO — BookBuilding
Same idea, but:
- Retail investors typically can't access directly — most IPOs go to institutionals and HNWIs.
- Some brokers (Robinhood, IBKR) offer limited retail IPO access.
- After listing, shares are freely tradeable.
Lock-up period
Early shareholders (founders, VCs, employees) usually agree not to sell for 90–180 days after IPO. This protects the stock price early on. When lock-up ends, large supply hits the market — price often drops.
Example: Allegro IPO (Oct 2020) priced at 43 PLN, jumped to ~80 PLN on day 1. Six months later, after lock-up release, price slid as PE investors unloaded.
Risks specific to IPOs
Underpricing
The stock jumps 20–100% on day 1. You benefit — only if you got an allocation. If you buy on day 1 after the pop, you're already too late.
Overpricing
The stock drops below offer price and stays down for months/years. Examples: UiPath, Robinhood (US), some Polish IPOs from 2021.
Volatility
First 3–6 months of trading are often chaotic — limited float, no analyst coverage, newsflow matters disproportionately.
Lack of history
Public-company-quality disclosures only since the prospectus. Harder to compare quarterly trends.
Insider selling post-lockup
Founders cash out → supply pressure → price drops.
How to participate in a Polish IPO
- Open brokerage account with a broker offering IPO access (PKO BP, Bossa, mBank, Santander — usually the ones acting as underwriters).
- Watch for upcoming offerings on GPW.pl, Bankier.pl, InfoStrefa.
- Read the prospectus — at minimum risk factors and financials.
- Submit subscription during the bookbuilding period (typically 5–10 days).
- Wait for allocation — you may receive fewer shares than requested (proration in oversubscribed deals).
- First trading day — decide to hold, add, or sell.
Famous Polish IPOs — case studies
| Company | Year | Offer price | Peak (first year) | Current (2026) |
|---|---|---|---|---|
| Allegro | 2020 | 43 PLN | 96 PLN | ~30–35 PLN |
| Dino Polska | 2017 | 33.5 PLN | steady climb | ~400+ PLN |
| LiveChat | 2014 | 18.5 PLN | strong runup | ~100 PLN |
| Ten Square Games | 2018 | 46 PLN | peak 600 PLN | post-crash ~80 PLN |
| Answear | 2020 | 25 PLN | decline | under offer price |
| Pepco Group | 2021 | 40 PLN | initial pop | volatile |
Lesson: some IPOs (Dino) became generational winners; others (Answear, Allegro post-hype) disappointed. Selection matters.
Global IPOs worth knowing
- Facebook (2012) — brutal first year, legendary comeback.
- Uber, Lyft (2019) — both below offer price for years.
- Airbnb (2020) — strong IPO, survived pandemic.
- Coinbase (2021) — peak day one, crashed 80% in bear market.
- Arm (2023) — strong debut.
Comparison with alternatives
| Strategy | Risk | Access (PL retail) | Typical return |
|---|---|---|---|
| IPO subscription | High | Moderate | Highly variable |
| Post-IPO buying (3–6M) | Medium | Easy | Lower variance |
| Established blue chips | Low-medium | Easy | 5–10%/year |
| Index ETF (WIG20, S&P 500) | Medium | Easy | 6–10%/year |
Common mistakes
- Buying on day 1 after a 50% pop — you're the greater fool.
- Skipping the prospectus because "everyone's talking about it".
- Over-allocating to one IPO (>10% of portfolio).
- Ignoring lock-up expiration dates.
- Assuming IPOs are cheap — most are priced to sell at high multiples.
- Confusing "hot IPO" with "good investment".

FAQ
Can retail investors in Poland buy US IPOs? Rarely at the offer price. Most US IPOs go to institutionals. After listing (usually day 1), you can buy through IBKR, XTB, Degiro at the market price.
How many shares do I get if I subscribe? Depends on demand. If the IPO is oversubscribed 5×, you get 20% of what you asked for. Hot deals are allocated proportionally.
Is there a minimum investment? In Poland typically 1–5 shares. In the US, no universal minimum — depends on the broker.
Should I sell on day 1 to lock in gains? Depends on your thesis. If you liked the company at the offer price and the thesis hasn't changed, hold. If you subscribed just for the "flip", then yes.
What's the best post-IPO strategy for quality companies? Wait 3–6 months for the initial hype + lock-up drama to settle, then assess whether the fundamentals justify the price. Dino, LiveChat rewarded patient buyers.
