When a stock falls below its IPO price — and everyone pretends they didn't see it coming.
A 'broken IPO' occurs when a newly listed stock trades below its offer price — either on the first day of trading or shortly thereafter. It signals that the offering was priced above what the market was willing to pay, that institutional demand was insufficient to support the price, or that the underwriter's stabilisation mechanisms (including the greenshoe) have been overwhelmed. Broken IPOs are associated with reputational damage to the underwriting bank and often precede extended underperformance.
An IPO breaks when buy demand in the open market is insufficient to sustain the offer price. This can happen immediately (stock opens below offer) or gradually (stock drifts down over days/weeks despite greenshoe support).
Underwriters typically defend the offer price using the greenshoe — buying shares in the open market when the stock falls. But if selling pressure exceeds the 15% overallotment they can deploy, the price breaks anyway. Once the greenshoe is exhausted and the stock is still falling, the floor disappears.
Broken IPOs often share common characteristics: aggressive pricing relative to peers, heavy insider selling in the offering, a business model that wasn't yet profitable, or deteriorating market conditions between the roadshow and listing date.
A broken IPO creates a psychological overhang. Investors who bought at the offer price are underwater and often sell once they can break even. This creates persistent selling pressure at the offer price — which becomes a resistance level rather than a floor.
WeWork's attempted IPO in 2019 is arguably the most famous broken IPO that never even happened — the valuation collapsed from $47 billion to under $10 billion during the S-1 review process and the deal was pulled entirely. When it eventually listed via SPAC in 2021 at a $9 billion valuation, it still proceeded to fall over 98% before filing for bankruptcy in 2023. Separately, Uber IPO'd at $45 in May 2019 and immediately broke — closing at $41.57 on day one. It spent most of its first year below the offer price. Rivian IPO'd at $78 in November 2021, briefly surged to $172, then collapsed below its offer price within months, eventually trading under $10 — an 87% decline from the IPO price. These are not outliers. Research suggests roughly 30–40% of IPOs trade below their offer price within 12 months.
A broken IPO is not automatically a buying opportunity. It often marks the beginning of a longer decline, not a temporary dip. The stock breaking its offer price means the institutional investors who took the deal at that price are losing money — these are the people with the most information and the most sophisticated analysis. If they're wrong, the odds of a retail investor being right are not high. Wait for the lock-up expiry, multiple earnings reports, and clear evidence of improving fundamentals before touching a broken IPO.
