For the same company, the route changes the timeline, the cost, the dilution and the odds. This page puts the three side by side and says which one fits which situation.
There are three routes: a traditional IPO (12-18 months, raises capital at listing, highest disclosure bar), a reverse merger (4-8 months, fastest, but usually brings no new money, and shell quality decides whether you can uplist), and a SPAC merger (6-10 months, the merger is the listing with cash already in trust, at the cost of sponsor-promote and redemption dilution). Which one depends on three things: whether your financials survive IPO-grade disclosure, how tight the window is, and whether you must raise money at the moment you list.
Every figure in the table below is either a market-practice range or written exchange rule. Items touching the 2026 rules are sourced on this site's dedicated rule page.
| Dimension | Traditional IPO | Reverse merger | SPAC merger |
|---|---|---|---|
| Market-practice timeline | 12-18 months | 4-8 months | 6-10 months |
| Raises at listing | Yes, offered at listing | Usually no; PIPE or placement later | Yes, trust cash lands at closing (net of redemptions) |
| Where it lists | Nasdaq / NYSE | OTC first, uplist once qualified | Nasdaq / NYSE |
| Main gate | Exchange financial and liquidity standards, plus an underwriter willing to take it | Shell cleanliness, plus Super 8-K audit statements at IPO standard | Post-combination entity must meet original listing standards |
| 2026 China-issuer rules | Firm-commitment raise of at least US$25 million | MVUPHS of at least US$25 million after combination; one year of continuous trading before uplisting from OTC | MVUPHS of at least US$25 million after combination |
| Where dilution comes from | New shares issued | Existing shell holders' shares | Sponsor promote (commonly around 20%), warrants, redemption shortfall |
| Biggest unknown | Issuance window and pricing | The shell's legacy liabilities, litigation and tax | Redemption rate and whether a PIPE fills the gap |
| Cost of switching late | High: structure and audit rework | Moderate: can pivot to a placement or later uplist | High: rework after S-4 / F-4 is filed |

Read the three routes as three different trade-offs rather than three speeds. Speed is the visible part; the real differences are the gate, the dilution and how much is under your control.
If you can live with 12-18 months of preparation and your financials are already close to disclosure standard (complete historical audits, related parties cleaned up, controls documented), an IPO is the cheapest route overall: capital at listing, an underwriter's endorsement, clean institutional ownership. The gate is not duration - it is whether the disclosure survives comment. SEC comment rounds do not get shorter because it is your first filing.
It is the fastest route (4-8 months), but two things must be settled first. One is shell cleanliness: legacy liabilities, pending litigation, tax and SEC filing history have to be reverse diligenced item by item - skip this and the uplist will be blocked. Two, it usually brings no new money, so post-listing financing depends on a PIPE or a placement, and both in turn require the company to already be disclosable. Under the 2026 rules a China-based issuer must also trade continuously on the prior market for one year before uplisting from OTC, which makes boarding first and switching seats later materially more expensive than it used to be.
A SPAC's value is that the merger is the listing and the cash is already in trust. For a company that must list by a certain date and does not want the issuance window deciding its fate, this is the most controllable route. The price is dilution: sponsor promote (commonly around the 20% level), warrant exercise and shareholder redemptions. Redemptions are the single biggest unknown - they decide how much cash actually lands at closing. A De-SPAC runs on S-4 / F-4 and 424(b), and SEC comment intensity is not discounted.
Saying so during the first call is worth more than taking the mandate and slipping for a year. In these five cases we say it up front.
No. Uplisting requires meeting the exchange original listing standards (financials, public float value, liquidity) and a clean shell - legacy liabilities, pending litigation, tax and SEC filing history all have to pass. Under the 2026 rules a China-based issuer must also have traded continuously on the prior market for one year before uplisting from OTC. Uplisting is not automatic; it happens after the homework skipped at merger time is finally done.
We will not quote a figure, because redemptions depend on trust size, where the secondary market price sits against trust value, the merger terms and whether a PIPE backstops the deal. Case-by-case variance is enormous and any single number misleads. What can be said: redemptions are the largest source of uncertainty in a SPAC, they decide how much cash actually lands at closing, and the buffer has to be designed into the merger agreement and the PIPE - not accepted as an outcome afterwards.
Strictly, no. OTC is off-exchange trading with no exchange-level financial, governance or disclosure requirements, and it is not an SEC-registered listing. The common pattern is to obtain a ticker and trading history on OTC, then uplist to Nasdaq or NYSE once the standards are met. Treating OTC as the destination is one of the most common misreadings in this market.
It depends on how late. Switching early (pre-filing) costs time and sunk preparation. Switching after an S-1 or S-4 is on file means rebuilding the structure, redoing the audit and re-explaining comments already answered - typically months and a substantial rework bill. That is why the 30-minute route diagnosis sits before any mandate: the route decision is the most expensive call in this whole exercise.
Reverse mergers and SPACs, most directly: both require MVUPHS of at least US$25 million after combination, and uplisting from OTC now requires a year of continuous trading first. Traditional IPOs require a firm-commitment raise of at least US$25 million. The common thread is that whether a real public market exists after listing has become a hard gate - below it, you only have a ticker.
