Polymarket traders are pricing an approximately 56% chance that SpaceX reaches a $3 trillion valuation by June 30, turning the company’s extraordinary post-IPO rally into one of the platform’s most closely watched technology markets.
The probability has climbed as SpaceX shares surged to around $213, lifting the company’s market value to roughly $2.8 trillion. At that level, SpaceX would need to gain only about 7% to cross $3 trillion, implying a share price near $228 if the outstanding share count remains unchanged.
That target no longer looks remote after SpaceX moved from a $1.77 trillion IPO valuation to almost $2.8 trillion in only a few trading sessions. Shares rose 11% on Tuesday as SpaceX overtook Amazon and briefly moved above Microsoft, placing the company among the five most valuable U.S. businesses.
The Market Only Needs One Regular-Hours Print
The Polymarket contract does not require SpaceX to close above $3 trillion on June 30. It resolves positively if the company reaches or exceeds the threshold at any point during official regular-hours trading before the deadline.
That settlement structure makes intraday volatility especially important. Options trading began with more than one million contracts changing hands by early afternoon, while bullish call demand contributed to rapid dealer hedging and sharp price movement.
The required stock price is also close to a level already seen in crypto derivatives. TradeXYZ’s SPCX perpetual contract reached $228.74 after Nasdaq closed, almost exactly where the listed stock would need to trade for a $3 trillion market cap.
That crypto price does not count toward the Polymarket settlement. The TradeXYZ product is a synthetic perpetual contract rather than official Nasdaq equity, and the prediction market uses regular-hours exchange prices following the IPO. Still, the print shows that some traders have already been willing to price SpaceX exposure around the required level.
Options, Index Flows And Cursor Fuel The Rally
The rally is being supported by several near-term demand drivers. SpaceX is moving toward fast-track Nasdaq-100 inclusion, while FTSE Russell and MSCI additions are expected later in June. Those events could force passive funds and index-tracking portfolios to acquire shares while the publicly available float remains relatively limited.
SpaceX has also agreed to acquire Cursor developer Anysphere for $60 billion, strengthening the market’s view of the company as a combined space, satellite connectivity and artificial intelligence platform.
The same demand has spread across crypto markets, where SPCX perpetual volume exceeded $1 billion again and tokenized SpaceX products continued trading after the Nasdaq session ended.
Extreme Valuation Meets Limited Float
The rally has pushed SpaceX above 150 times its 2025 revenue of $18.67 billion, despite the company recording a $4.94 billion net loss after combining with xAI. That valuation leaves the stock exposed to sharp reversals if momentum fades or early holders begin selling.
Polymarket’s pricing reflects that tension. Traders see the $3 trillion threshold as slightly more likely than not, but the 44% probability assigned to failure remains substantial. With the implied target near $228 and the deadline on June 30, regular-hours SPCX trading, options positioning and index-related buying now determine whether the prediction market pays out.
