Pre-IPO vs IPO Investing: What's the Difference and Which Is Right for Australian Investors?

Pre-IPO investing means buying shares in a private company before it lists on a public exchange. IPO investing means buying shares either through the initial public offering itself (allocated to selected investors at the offering price) or on the first day the company trades publicly. The two strategies look superficially similar because they both involve newly accessible companies, but they capture fundamentally different parts of the value creation curve, carry different risk profiles, and require different investor eligibility and capital commitments.

For Australian investors, the choice between them is not a binary preference. It is a portfolio question shaped by your access to private market deal flow, your willingness to commit illiquid capital, and your view on where the most attractive entry points sit. The data on returns at each stage tells a clearer story than most investors realise.

This article explains how each strategy works, what the academic and market data shows about returns, who qualifies for each pathway in Australia, and how to think about the decision in the context of a broader portfolio.

What pre-IPO investing actually involves

Pre-IPO investing gives you economic exposure to a private company through one of several access structures. The most common in Australia is the SPV (special purpose vehicle), a legal entity created to hold shares in a single private company on behalf of multiple investors who pool capital. Platforms like NonPublic source the shares from existing holders (early employees, venture investors, or institutional shareholders seeking liquidity) and structure them into SPVs that qualified Australian investors can participate in.

The entry point matters. A pre-IPO position in a company like SpaceX or Anthropic acquired today gives you exposure at the most recent secondary market valuation, which sits somewhere between the company's last primary funding round and the eventual IPO price. For mature private companies approaching a listing, this entry point is typically lower than where the public market will eventually price the shares, but higher than where early venture capital investors entered.

The trade-offs are real. Capital is locked until a liquidity event such as an IPO, acquisition, or secondary sale. There is no public price discovery between funding rounds, so the value of your position can move without visible market signals. You need to qualify as a wholesale or sophisticated investor under the Corporations Act 2001, and minimum investment sizes are generally higher than buying listed shares.

The compensating advantage is access to the growth that happens before listing. Modern technology companies are staying private for longer (the median US company now IPOs roughly 12 years after founding, up from approximately four years in 1999), and the majority of their value creation now happens before they list. Investors who only access these companies post-IPO are buying mature businesses, not growth equities in the traditional sense.

What IPO investing involves

IPO investing covers two distinct activities that get conflated in casual discussion.

One is participating in the IPO allocation itself, where you receive shares at the offering price set by the underwriters before the stock begins trading. In Australia, allocation is typically available through major retail brokers (CMC Markets, CommSec, NABTrade) for ASX listings, and through international brokers (Stake, Interactive Brokers) for select US listings. For retail investors, allocation is generally limited and rarely fills the requested order size for popular offerings. Institutional investors and underwriter clients receive priority, which is one of the structural features that produces IPO underpricing.

The other activity, often confused with the first, is simply buying shares on the first day of trading or shortly after listing. Any investor with a brokerage account can do this, but they are paying the post-pop price discovered by the public market rather than the offering price negotiated by the underwriters. The economic difference between these two activities is large. If you receive allocation at the IPO price and the stock pops 20% on day one, you have captured that 20% return without committing capital for more than a day. If you buy on day one after the pop, you are paying the post-pop price as your entry point, and your return depends on what happens from there.

The data on returns at each stage

This is where the analysis gets genuinely educational, because the academic and market data tells a more nuanced story than either pre-IPO or IPO marketing materials typically acknowledge.

IPO underpricing and the first-day pop

The most extensively studied feature of IPOs is the first-day pop, the gain from the offering price to the first-day closing price. Jay Ritter's IPO database at the University of Florida, the canonical academic source on IPO returns, documents that from 2001 through 2023, the average first-day pop for US IPOs has been approximately 17.5%. The pattern is consistent over decades. During the dot-com peak of 1999-2000, the average pop reached approximately 65%. In recent years it has settled back to the 17-18% range with occasional outliers (Figma's 250% first-day pop in July 2025 being a notable exception).

This consistent underpricing exists because investment banks deliberately price IPOs below their expected first-day market price. The reasons are partly defensive (avoiding the embarrassment of a deal that prices below the offering) and partly relational (rewarding institutional clients who provide consistent deal flow). Wall Street Journal analysis of Figma's IPO estimated the company left approximately US$3 billion on the table by underpricing the offering relative to first-day demand.

For investors who can secure IPO allocation, this underpricing represents genuine value capture. For investors who cannot (which includes most retail and many wholesale investors in Australia for US listings), the first-day pop is value they cannot access. Buying after the pop means paying the higher post-pop price.

Long-run post-IPO performance

The less-discussed counterweight to first-day returns is what happens over the following three to five years. Ritter's foundational 1991 paper in the Journal of Finance documented that US IPOs between 1975 and 1984 substantially underperformed a sample of matched companies from the first-day closing price to their three-year anniversaries. Loughran and Ritter's 1995 follow-up extended this to a sample of 4,753 IPOs between 1970 and 1990, finding the underperformance extended to five years after issue.

Ritter's most recent updated statistics through 2025 show that long-run underperformance relative to other firms of the same size and book-to-market ratio has averaged 2.1% per year on an equally weighted basis. Companies that went public in high-volume IPO years performed worst. Companies with negative earnings at IPO performed substantially worse than companies with positive earnings.

The directional finding is consistent across decades and markets. IPOs deliver attractive short-term returns from the offering price to the first-day close, then underperform comparable companies over the medium-term holding period. This is the academic literature's "new issues puzzle" and it has been replicated across the US, UK, and other developed markets.

Pre-IPO returns

Pre-IPO returns are harder to systematise because there is no continuous price discovery mechanism. The relevant comparison is between the secondary market entry price and the eventual IPO offering price or post-IPO trading price.

For mature late-stage private companies, the data points are illustrative even without continuous tracking. SpaceX was valued at US$50 billion in late 2020 (when Pengana Private Equity Trust first invested) and is preparing for an IPO at up to US$1.75 trillion in 2026. Anthropic was valued at US$15 billion in early 2024 and now trades on secondary markets at approximately US$1 trillion. OpenAI was valued at US$29 billion in early 2023 and currently trades at approximately US$850 billion.

These are individual data points rather than systematic averages, and they reflect a particular market environment for AI and defence technology companies. But the structural pattern is consistent: investors who entered these companies at earlier private market stages have captured substantial returns before any IPO, and the gap between secondary market pricing and eventual IPO valuation continues to compress as listings approach.

Cambridge Associates' US Venture Capital Index, which captures professionally managed venture investments, returned 6.4% in the first half of 2025 and has outperformed public market benchmarks substantially over longer horizons. Top-quartile US private equity funds delivered a 22.5% IRR between 2000 and 2020, exceeding public market benchmarks by 35%. These figures reflect manager returns rather than individual investor returns, but they map onto the same underlying asset class that pre-IPO SPV structures access.

Where the value gets created versus where it gets captured

This is the most important framework for thinking about the pre-IPO vs IPO question, and it is the one most generic explainers miss.

Modern technology companies create the majority of their economic value while still private. Andreessen Horowitz research found that companies in recent IPO cohorts generated more than 50% of their total market capitalisation while still private. For earlier vintage IPOs from 2014 to 2019, more than 80% of value was created after listing, but that ratio has inverted as companies stay private for longer.

The practical implication runs counter to most retail investor intuition. The IPO is no longer the primary value capture event. By the time SpaceX, OpenAI, or Anthropic actually lists, much of the compounding has already happened. The post-IPO investor is buying a mature business at a price that reflects forced index inclusion demand, institutional allocation processes, and the existing private market valuation rather than the growth runway ahead.

Pre-IPO investing captures the part of the curve where companies are scaling from "valuable" to "extraordinarily valuable." IPO day investing captures a small short-term pop from underpricing if you have allocation. Post-IPO investing in the first three to five years tends to underperform matched comparable companies according to the academic data.

The asymmetry is the original observation that follows. The investor with pre-IPO access is participating in the asset class during its highest-return phase. The investor who waits for the IPO is arriving in time for the underpricing pop (if allocation is secured) but then facing a base rate of underperformance over the medium-term horizon. Both can produce attractive outcomes, but the structural odds favour earlier entry for investors who can absorb the illiquidity.

How Australian investors actually access each strategy

Pre-IPO access in Australia

Pre-IPO investing in Australia is restricted to wholesale and sophisticated investors under section 761G and section 761GA of the Corporations Act 2001. The qualification thresholds and certification process involve net assets of at least A$2.5 million, gross income of at least A$250,000 per annum, or a single investment of A$500,000 or more in a specific product. The NonPublic platform handles the wholesale investor verification process as part of investor onboarding.

For qualified investors, the access infrastructure has expanded considerably. Platforms like NonPublic, operating under Australian Financial Services Licence #482668, provide curated SPV access to pre-IPO companies including SpaceX, OpenAI, Anthropic, Anduril, Perplexity, Discord, and Databricks. Minimum ticket sizes vary by deal, but typically sit between A$10,000 and A$50,000.

The Pengana Private Equity Trust (ASX: PE1) offers ASX-listed exposure to a diversified portfolio that includes pre-IPO holdings, with SpaceX and other private companies among the underlying positions. The trade-off is meaningful dilution of any single position's contribution to your returns, plus the discount to NAV at which PE1 typically trades.

IPO access in Australia

IPO allocation in Australia is most readily available for ASX listings through major retail brokers. CMC Markets, CommSec, NABTrade, Stake, and CMC Invest all offer access to selected ASX IPOs, though allocation for popular offerings is typically rationed. For US IPOs, Australian investors can participate through international brokerage platforms (Stake, Interactive Brokers) when allocation is made available, but most retail-tier allocation goes to US-domiciled brokerage clients first.

For major US IPOs of broad interest, including the expected SpaceX, OpenAI, and Anthropic listings, Australian retail investors will most commonly access the offering by buying on the first day of trading at the post-pop price rather than receiving allocation at the offering price. This is a meaningful structural disadvantage that affects which strategy is realistically available.

Wholesale and sophisticated investors with established relationships at international institutional brokers may have access to allocation, but this is dependent on the specific broker, the specific deal, and the existing relationship rather than something that can be assumed.

Which strategy is right for which investor

The two strategies serve different objectives, and most investors who can access both should think about them as complementary rather than competitive.

Pre-IPO investing suits investors who qualify as wholesale or sophisticated under Australian law, have meaningful long-term capital they can commit to illiquid positions, want concentrated exposure to specific companies rather than diversified fund exposure, and accept that holding periods may extend three to seven years before a liquidity event. The reward for accepting these constraints is access to the value creation phase that academic research suggests captures most of the long-run returns in modern technology businesses.

IPO investing suits investors who prefer listed-market liquidity, can secure meaningful allocation at the offering price (a real constraint for most Australian retail investors accessing US listings), and have a defined exit strategy if the first-day pop produces an attractive short-term outcome. For investors who cannot secure allocation, buying on the first day of trading exposes you to the post-pop price plus the documented long-run underperformance pattern.

Buy-and-hold post-IPO investing in the first three to five years after listing is the pattern with the weakest historical performance according to the academic literature. Exceptional companies do continue to compound after listing, and the average masks substantial variation. The base rate, though, suggests that systematic IPO investing without the ability to secure allocation is the least attractive of the three strategies for most investors.

The practical implication for Australian portfolios

For Australian wholesale and sophisticated investors, the structural argument favours building meaningful pre-IPO exposure to companies you have conviction in, then making decisions about whether to hold or sell at the IPO based on the specific entry price and outlook at that point.

Pre-IPO positions in SpaceX, Anthropic, OpenAI, or Anduril acquired today give you exposure ahead of expected 2026 and 2027 listings. If the IPOs price strongly, you have the option to sell at listing and capture both the pre-IPO appreciation and any IPO-day pop. If the public market initially underprices the company relative to the long-term opportunity, you can hold through the listing and into the public market phase.

This is the same structural approach institutional venture capital investors and family offices use, and it reflects the underlying economics of where value gets created versus captured in modern technology companies.
