SpaceX just filed to go public — and the numbers are out of this world. A potential two-trillion-dollar valuation, a prospectus that reveals rockets, satellites, and AI ambitions, and a founder who keeps 85% of the voting control while selling shares to the rest of the planet. In this episode, we break down the biggest IPO story in history and pick up five B2+ expressions that are essential for anyone navigating business news, finance conversations, or the English-speaking workplace.
⚡ 5 Key Expressions
Expression 01
Go public
When a private company goes public, it lists its shares on a stock exchange and makes them available for anyone to buy. Before going public, ownership is usually limited to founders, employees, and early investors. The IPO — initial public offering — is the moment it crosses that line. "Go public" follows the common English pattern of "go" plus a state: go viral, go live, go bankrupt. But it also works for people: if someone reveals a private matter openly, they have "gone public" with it. SpaceX filing its S-1 with the SEC is the first major step toward going public.
- "The startup had been private for twelve years before it finally decided to go public on the Nasdaq."
- "She went public with her concerns about the merger before the board had a chance to respond."
Expression 02
Prospectus
A prospectus is the official document a company must file with financial regulators before going public. It is required by law and must disclose everything investors need to make an informed decision: revenue, net losses, business model, risks, executive compensation, and future plans. Think of it as the company's financial confession — nothing material can be left out. In the US, this document is also called an S-1. Beyond finance, the word carries over into academia: a doctoral prospectus outlines a PhD candidate's research plan. In both cases, the concept is the same — a detailed declaration of intent, backed by evidence.
- "Analysts combed through the prospectus overnight and flagged the AI division's losses as a key risk factor."
- "Before submitting her dissertation, she spent three months writing a prospectus to get committee approval."
Expression 03
Surpass
To surpass something means to go beyond it — to exceed a record, outperform a competitor, or exceed what was previously thought possible. It is a more formal and precise alternative to "beat" or "overtake," and it works equally well with numbers, expectations, and abstract concepts. You can surpass a sales target, surpass a rival company, or surpass what experts predicted. SpaceX's IPO is expected to surpass Saudi Aramco's 2019 offering, which currently holds the record for the largest IPO in history. The word carries a sense of meaningful achievement — not just winning, but going significantly further.
- "Revenue for the quarter surpassed analyst expectations by nearly fifteen percent."
- "She trained for two years, and when she finally competed, she surpassed every personal record she had set."
Expression 04
Voting control
Voting control refers to holding enough shares — or the right class of shares — to determine outcomes in company decisions without needing agreement from other shareholders. Not all shares are equal: many tech companies issue dual-class share structures, where founders keep high-vote shares and public investors receive low-vote shares. This means a founder can sell a large portion of the company while retaining full decision-making power. Elon Musk will hold 85% of SpaceX's voting control after the IPO — meaning he can set strategy, approve mergers, and determine leadership without being overruled. Understanding this distinction is essential when reading any corporate governance story.
- "Despite owning less than twenty percent of the shares, the co-founder retained voting control through a dual-class structure."
- "Investors were concerned that no single shareholder had enough voting control to challenge the board's decisions."
Expression 05
Total addressable market
Total addressable market — almost always abbreviated as TAM — is the theoretical maximum revenue a company could generate if it captured every possible customer in every market it operates in. It is one of the first questions investors ask when evaluating a business: "What's your TAM?" A large TAM signals that even a small slice of the market could generate significant revenue. A small TAM means growth will be inherently limited. SpaceX claims a TAM of $28.5 trillion, spanning rockets, satellite internet, and AI infrastructure. The key word is theoretical — TAM is the ceiling of what's possible, not a projection of what a company will actually achieve.
- "The pitch deck opened with a slide showing a total addressable market of four hundred billion dollars — which got every investor's attention."
- "Their TAM looks impressive on paper, but they'd need to dominate three separate industries to come close to capturing it."
🎭 The Dialogue: Launch Window
Maya is an engineer and Alex works in finance. They're catching up over lunch and end up deep in a conversation about the biggest business story of the week.
📍 Office lunch spot, midday. Alex has his phone out. Maya is already halfway through her sandwich.
Maya: Did you see that SpaceX finally filed to go public? I've been waiting for this for years.
Alex: I read through part of the prospectus this morning. Two trillion dollar valuation — it could surpass Saudi Aramco as the biggest IPO ever.
Maya: And Musk keeps eighty-five percent of the voting control, so nothing really changes at the top.
Alex: Right. He's selling shares but not power. Classic move.
Maya: What surprised me was the total addressable market they're claiming — twenty-eight point five trillion dollars.
Alex: I saw that. Rockets, satellite internet, AI data centers — they're basically saying the whole future economy is their playground.
Maya: As an engineer, I'll believe it when I see it. They're still losing money on the space side.
Alex: Fair. But if anyone's going to surpass what people think is possible, it's probably them.
🧠 Episode Quiz
Can you answer this?
SpaceX's Starship is the most powerful rocket ever built. But the company's very first rocket had a much harder beginning — it failed on its first three launch attempts, nearly destroying the company. What was the name of that original rocket?
- A — Falcon 1
- B — Dragon 1
- C — Merlin
✅ Answer: A — Falcon 1. SpaceX's first rocket failed three times before its fourth attempt in September 2008 became the first privately developed liquid-fueled rocket to reach Earth's orbit. The company had enough funding for exactly that fourth launch. Had it failed, SpaceX would likely have shut down — and the two-trillion-dollar IPO story wouldn't exist.
📚 Bonus Vocabulary
Valuation (noun) — the estimated total value of a company, calculated based on share price and the number of shares outstanding. SpaceX's IPO could give it a valuation of two trillion dollars. Valuation is distinct from revenue or profit — it reflects what the market believes a company is worth, not what it has earned. "The startup's valuation doubled after its Series B funding round, despite still operating at a loss."
Brokerage account (noun phrase) — a financial account held with a licensed broker that allows the account holder to buy and sell investments such as stocks, bonds, and ETFs. Going public means SpaceX shares will become available through standard brokerage platforms like Fidelity, Schwab, or Robinhood. "She opened a brokerage account specifically to buy shares on the first day of trading."
Aspirational (adjective) — relating to something that is hoped for or aimed at, rather than already achieved. TAM figures in startup pitch decks are aspirational — they represent the best possible outcome, not a guarantee. "The five-year plan was ambitious and aspirational, but the team believed it was achievable."
