SpaceX IPO: Closing Share Price

Platform comparison

Active sub-markets

Market context

SpaceX remains privately held, with Elon Musk retaining majority control through his role as Chief Engineer and CEO. An initial public offering would represent one of the most significant capital-markets events in aerospace history, potentially valuing the company at $100–200 billion based on recent private fundraising rounds. The settlement window closes in mid-June 2026, meaning the market resolves if SpaceX lists before that date; if no IPO occurs by 31 December 2027, the market resolves to "No IPO before 2028" rather than settling on a share price.

In prediction markets, a YES share represents a bet that the event occurs; a NO share bets against it. Here, YES holders would profit only if SpaceX lists and the market then resolves to a specific price bracket. The 0% implied probability reflects the absence of any announced IPO timeline or regulatory filing. Comparable precedents—including Blue Origin's continued private status and the delayed debuts of other space-sector firms—illustrate how aerospace companies often prioritise operational milestones over public markets. Relatedly, Musk's historical reluctance to take Tesla private in 2018 and his subsequent management of that company's volatility suggest mixed signals about his appetite for public-market scrutiny.

Catalysts to monitor include SpaceX's Starship development progress, regulatory approvals for commercial space activities, and any statements from Musk or the board regarding capital-raising strategy. Recent funding rounds in 2023–2024 valued the company at $180 billion, reducing immediate pressure for an IPO. Traders should track quarterly announcements from SpaceX's major customers (NASA, the US Space Force, commercial satellite operators) and any changes to the company's debt or equity structure, as these could signal shifting financial priorities.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

FAQ

How does resolution work?

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

Zero. Prediction Market UK routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
