Space Exploration Technologies Corp. faces shifting market expectations regarding its Starship launch capabilities in 2026, while its Chief Executive Officer Elon Musk continues to advocate for solar energy to power artificial intelligence. Polymarket, a Polygon-based prediction platform, currently assigns a 40% probability that fewer than five Starship launches will successfully reach space this year, a decrease from 56% a week prior. Traders have wagered over $470,000 on the outcome, which defines a successful launch as a vehicle lifting off and climbing at least 62 miles above sea level between Jan. 1 and Dec. 31.

The platform indicates a 28% chance of 5–6 successful launches and a 14% probability of 7–8 successes. These wagers follow a recent test flight of SpaceX's upgraded Version 3 Starship in May. During that mission, the upper stage completed a successful flight, released 20 test satellites, and splashed down safely. However, the Super Heavy booster experienced engine failures during its return and crashed rather than performing a controlled descent.

The Federal Aviation Administration classified the booster crash as a mishap and is overseeing an investigation, suspending flights until the probe concludes. Starship remains central to Musk's strategy to expand SpaceX's spaceflight capacity and eventually transport humans to Mars. The company has invested more than $15 billion in the development of the rocket.

Separately, Musk commented on the energy requirements for future AI systems. "It is humbling to consider that if we harness just 1 millionth of the Sun's power for AI, that will be much more than a million times the intelligence of all of humanity," Musk stated on social media.

SpaceX stock rose 2.06% in after-hours trading after closing 4.83% higher at $201.80 during Monday's regular trading session.

Polymarket Prediction Data

Space Exploration Technologies Corp. (NASDAQ: SPCX) debuted in the stock market last Friday and added roughly $800 billion in market cap in two trading days. Retail traders were a major force behind the surge, flooding options desks and lighting up message boards within minutes of the open. The stock was up 10.70% at $213.09 at the time of publication Tuesday. This rapid appreciation highlights a disconnect between traditional valuation models and current market sentiment, as investors focus on the company's potential rather than its current financial metrics.

Retail investors are sharing their views and strategies on Reddit Inc. (NYSE: RDDT). "Your mistake is trying to understand SPCX," one user wrote in a thread that has become a manifesto for retail traders. "Just like people trying to understand Tesla lol," another user responded. The Tesla parallel runs deep, with buyers applying the same logic they used for Tesla Inc. (NASDAQ: TSLA), which traded at multiples that defied conventional sense for years.

Valuation vs. Speculation

"No one cares about valuation when there are always people looking to speculate," one commenter wrote. "Tesla has been trading flat, so people will start pouring money into SpaceX. It’s not a long-term stock, just short-term speculation." The underlying fundamental case is complicated. Morningstar pegged SpaceX’s discounted cash flow value at $780 billion — less than half its IPO valuation of $1.77 trillion.

Analysts at Payload Space project Starlink will account for roughly 79% of SpaceX’s total 2026 revenue. A company trading near $2 trillion is therefore largely a bet on whether a satellite internet service can penetrate markets that may lack the income to sustain it. "Lol no one is buying SPCX on fundamentals," another commenter wrote. "You’re either fundamentally lying to yourself or fundamentally bad at maths."

New Leveraged ETF Launch

Amid this volatility, Defiance ETFs launched the Defiance Daily Target 2X Long SpaceX ETF (BATS: SPCU) on Monday. This fund is designed to provide leveraged exposure to SpaceX, aiming to deliver 200% of the daily performance of SPCX. Sylvia Jablonski, Chief Investment Officer at Defiance ETFs, stated that investors may be making a mistake by viewing SpaceX through the lens of traditional aerospace firms. She argues SpaceX should be viewed as a multi-platform infrastructure company spanning launch, communications, defense, AI connectivity, and space-based data services.

The SPCU is intended for investors looking to take a short-term view of the stock. Jablonski noted that volatility should be expected, particularly given the history of large IPOs. "None of that matters, get in, or miss out," wrote one Reddit bull, summarizing the prevailing sentiment that Wall Street is happy to sell the product alongside retail traders.
