SpaceX IPO Tracker

SpaceX IPO—debut complete, tracking the aftermath

SpaceX announced its IPO the week of June 11, 2026, and both the pre-debut "where will it price" book and the debut-month closing books have now settled. Traders had priced a debut close above $2 trillion (CNBC, June 11); the charts below show where the debut-month closing-market-cap and closing-price books resolved.

With the debut settled, the live story is the 2026 IPO calendar and peer frontier-tech valuations: Kalshi's KXIPO-26 on which companies officially announce an IPO this year, Polymarket's ipos-before-2027 Multiple, and the Anthropic and OpenAI closing-market-cap books.

Debut valuation—how SpaceX priced

Polymarket's will-spacexs-valuation-hit-by-june-30 Multiple and the spacex-closing-market-cap-end-of-ipo-month Categorical priced the debut number two ways—a strike chain and a full distribution. Both have now settled; together they are the cross-strike record of where the debut landed.

Closing price and the 2026 IPO calendar

Polymarket's closing-price up/down Single tracks whether SpaceX finishes its first month above or below the debut print, next to the broader IPO calendar: Polymarket's ipos-before-2027 Multiple and Kalshi's KXIPO-26 on which companies officially announce an IPO this year.

Peer frontier-tech valuations

The debut prints against its peers. Polymarket lists closing-market-cap books on Anthropic (Range) and OpenAI (Categorical)—the cross-asset backdrop for how the market is valuing the frontier-tech IPO class as SpaceX goes first.

What to watch

• How the debut settled. The will-spacexs-valuation-hit-by-june-30 strike chain and the spacex-closing-market-cap-end-of-ipo-month Categorical priced the same debut number two ways; both have settled. Where the ladder's median and the Categorical's modal bucket landed is the reference for the next frontier-tech debut.
• The $2T line. Traders priced a debut close above $2 trillion; the settled closing-market-cap distribution shows whether it cleared that round number.
• The 2026 IPO calendar. With SpaceX public, watch Kalshi's KXIPO-26 and Polymarket's ipos-before-2027 for which frontier-tech names announce next.
• Peer valuations. Watch the Anthropic and OpenAI closing-cap books—if frontier-tech IPO appetite reprices after the SpaceX debut, the peers move with it.
