Almost everyone watches the first-day price. Professional investors watch something else: when the next wave of paper hits the market, and whose it is.

SpaceX debuted and became one of the largest listed companies from day one. It is the moment when almost everyone looks at price, valuation and headlines.
There is a more useful question than any of those: who can sell their shares before you? This article is about the supply calendar, which is what people who have done this for years actually watch.
The general belief is that after a listing, founders and large funds are locked up for six months. That was true for a long time.
Today many deals include early-release clauses: if the price holds a set percentage above the offer price for a certain number of sessions, some early shareholders can begin selling far sooner.
The effect is counterintuitive and worth understanding: the better the stock does, the earlier the exit door opens. Precisely when the most people are buying for fear of missing out, a group appears that is cleared to sell.
When a company lists, people assume it is raising money to grow. Not always: in many deals a portion of the shares offered belongs to existing investors. That money does not go into the company; it goes into the seller's pocket. The prospectus distinguishes the two, but you have to go looking.
Some funds do not even need to sell to get liquidity: they can borrow using the shares as collateral. That monetises the position and cuts risk without generating a visible sale in the market. To anyone watching volume alone, nothing happened.
Releases are rarely a single event. They usually arrive in tranches tied to dates or milestones — the first quarterly report, for instance — and each tranche is a separate test for the price.
A newly listed share price forms with very little paper available. While supply is scarce, buyers compete with each other. When abundance arrives, sellers compete.
That is not a prediction of a fall: it is simply a change in who carries the pressure. And it will repeat, because OpenAI and Anthropic are next.
Before buying a newly listed company, the question is not whether the business is good. It is whether you are buying the start of a great story or the shares somebody has spent years waiting to sell. Both can be true at once, and the difference is the price you pay.
The common belief is 180 days, and for a long time that held. Today many deals include early-release clauses: if the price stays a set percentage above the offer price for a given number of sessions, some early shareholders can start selling much sooner.
Because early-release clauses are triggered by price: the better the stock does, the sooner the exit door opens. Exactly when the most people are buying out of fear of missing out, a group becomes authorized to sell.
Three things: whether part of the offered stock belongs to existing shareholders — that money does not go to the company — whether there are loans collateralized by shares, which monetize a position without a visible sale, and the schedule of release tranches, which is rarely a single event.
