Will SpaceX's market cap be between $1.0T and $1.5T at market close on last trading day of IPO month?

Prediction markets put the probability at 7%: Will SpaceX's market cap be between $1.0T and $1.5T at market close on last trading day of IPO month. Currently, markets see this as unlikely (7% YES). SpaceX gains 4% after surpassing Amazon in market cap.

What’s Happening

As of June 23, 2026, the prediction market assessing whether SpaceX's market cap will be between $1.0T and $1.5T at market close on the last trading day of IPO month has settled at a 7% YES probability, reflecting a dramatic collapse in the company's valuation from its post-IPO peak. The stock, which debuted on the Nasdaq on June 12, 2026, surged over 62% in its first days, briefly pushing the market cap above $3 trillion and surpassing Amazon as the world's fifth most valuable company. However, that rally reversed sharply: on Monday, June 22, SpaceX shares tanked 16%, wiping out approximately $400 billion in market value and bringing the market cap down to roughly $2 trillion at close. The selloff accelerated in premarket trading on Tuesday, June 23, with shares dropping another 2%, as initial euphoria gave way to profit-taking and valuation concerns [CNBC, Jun 23].

The sharp decline has made the $1.0T to $1.5T range the central battleground for traders assessing the stock's trajectory through the end of the IPO month. For the market to resolve at YES, SpaceX's market cap must close within that band on the last trading day of June, requiring a further drop of 25% to 50% from the $2 trillion level seen on Monday. The company's post-IPO volatility is historically extreme: the 16% single-day drop on June 22 is the largest for any U.S. company of comparable size since the 2020 pandemic-era swings. Meanwhile, SpaceX disclosed a $100.8 billion cash pile on June 22 and launched an inaugural bond sale to fund an ambitious AI and data center buildout, signaling that the company is prioritizing long-term capital expenditure over near-term stock price stability [CNBC, Jun 22].

The probability that SpaceX's market cap will be between $1.0T and $1.5T at market close on the last trading day of IPO month now hinges on whether the selloff stabilizes or deepens. Key indicators to watch include the 10-year Treasury yield, which has been hovering near 4.2%, and the June 26 release of the Personal Consumption Expenditures (PCE) price index, the Fed's preferred inflation gauge. A hotter-than-expected PCE reading could trigger a broader tech selloff, accelerating SpaceX's decline toward the $1.5T upper bound. Conversely, a dovish reading could spark a relief rally, keeping the stock above the $1.0T floor. The IPO lock-up expiration for early investors, typically 90 to 180 days post-listing, remains a medium-term risk, but for the current month, the market is pricing a 93% NO outcome, implying that most traders expect the market cap to remain above $1.5T or fall below $1.0T by month-end [Crypto Briefing, Jun 18].
