The Risks of Pre-IPO Investing
Nine structural risks that apply to every pre-IPO investment regardless of company quality — and the framework disciplined investors use to price them.
The companies that succeed in this category — Stripe through its core payments expansion, SpaceX through the Starlink ramp and its June 2026 listing, Anthropic during the enterprise AI cycle — have generated extraordinary returns for holders who entered early and waited.
The companies that failed — WeWork in 2019, FTX in 2022, and the long list of unicorns that never reached liquidity — generated complete losses for retail-accessible vehicles. The asymmetric distribution of outcomes is the defining feature of the category, and it is consistently underestimated by investors evaluating individual opportunities.
The Ten Structural Risks
01 Illiquidity
Unlike public markets, there is no exchange where investors can sell private shares whenever they choose.
Liquidity usually depends on one of a small number of events:
- IPO
- Acquisition
- Tender offer
- Approved secondary transaction
Until one occurs, investors may simply have to wait.
That waiting period is frequently measured in years rather than months.
Many of today's largest technology companies remained private far longer than investors expected.
Example
Stripe was founded in 2010 and remains private in 2026 — sixteen years of illiquidity for early investors.
SpaceX was founded in 2002 and listed in June 2026 — twenty-four years from founding to liquidity for its earliest backers.
The investment thesis may be correct while the timing proves dramatically different than expected.
02 Information Asymmetry
Public companies publish audited financial statements, quarterly filings, executive compensation, governance disclosures, and extensive regulatory reports.
Private companies generally do not.
Outside investors often receive only limited information, particularly in secondary transactions.
That means investors frequently make decisions without knowing:
- current financial performance
- customer concentration
- profitability
- fundraising plans
- internal governance
- future dilution
The less information available, the more uncertainty must be reflected in the investment decision.
03 Valuation Discontinuity
Private company valuations are not established through continuous public trading.
Instead, they are determined through negotiated financing rounds, secondary transactions, or internal appraisal methodologies, each of which may produce materially different outcomes.

04 Dilution
Ownership percentages rarely remain constant.
As companies raise additional capital, issue employee equity, or restructure ownership, existing shareholders often experience dilution.
The business may become substantially more valuable while an individual investor owns a smaller percentage of it.
Dilution is not necessarily negative.
It becomes problematic when investors fail to account for future fundraising in their expected returns.
05 Lock-Up Provisions
Even after an IPO, investors often cannot immediately sell their shares.
Lock-up agreements commonly restrict sales for several months following a public listing.
These restrictions are designed to reduce immediate selling pressure but create an additional layer of illiquidity.
In pooled investment vehicles such as SPVs, additional lock-up provisions may exist inside the vehicle itself, extending practical liquidity beyond the company's own restrictions.
A successful IPO does not necessarily mean immediate access to capital.
06 Share Class Stratification
Not every investor owns the same security.
Different share classes can carry different voting rights, liquidation preferences, conversion rights, information rights, and transfer restrictions.
These structural differences frequently matter more than headline valuation.

07 Exit Uncertainty
Most private companies never reach a traditional IPO.
Some are acquired.
Some remain private indefinitely.
Some conduct occasional tender offers.
Others eventually fail.
The timing—and even the existence—of an exit should never be treated as certain.
An investment should be evaluated on the possibility that liquidity takes substantially longer than expected or never arrives.
08 Regulatory and Tax Risk
The regulatory framework surrounding private securities changes over time.
Accreditation standards, securities regulations, taxation, disclosure rules, and transfer requirements may all evolve during the life of an investment.
Because holding periods often span many years, investors should expect the regulatory environment to change before liquidity occurs.
09 Permanent Capital Loss
Private investments carry the possibility of complete loss.
High-profile venture successes attract attention because they produce extraordinary returns.
Far less visible are the large number of private businesses that fail to achieve sustainable economics, raise additional financing on unfavorable terms, or ultimately become worthless.
The probability distribution in venture investing is highly asymmetric.
A small number of exceptional outcomes historically generated the majority of industry returns.
Many investments produce modest gains.
Some produce complete losses.
Risk should therefore be evaluated at the portfolio level rather than through individual company stories.
10 Transfer Restriction
Almost every private company holds a right of first refusal on share transfers, and many stock plans prohibit transfer outright without board consent.
A buyer and seller can agree terms, sign documents, and still have the transaction blocked—the company simply matches the offer and takes the shares itself.
This is not an edge case.
It is the standard structure of private company equity.
Example
A secondary purchase agreed at a negotiated price can sit through a 30-day notice period before the buyer learns whether they own anything.
Verification Note: Notice periods vary by company documents. Thirty days is common in many venture-backed shareholder agreements but should be confirmed for the specific issuer before relying on it.
Where to Go From Here
The structural risks above apply to every position in this category regardless of company quality. What changes between investments is the probability distribution of outcomes, not the risk framework itself.
With the framework in place, three things are worth understanding before evaluating any single name: how the routes differ, how private valuations are actually set, and what an SPV interest actually is.
