Space Exploration Technologies Corp. options began trading Tuesday on Cboe Global Markets and Nasdaq, marking one of the most closely watched options launches in years. Analysts warn the launch could trigger a gamma squeeze, a rapid price surge driven by options market mechanics rather than company fundamentals, potentially pushing the stock to $400 per share. The launch comes despite SpaceX posting a net loss of $4.28 billion in Q1 2026, making it the only publicly traded company over $1 trillion in market cap that is not generating profit.

Gamma Squeeze Risks

Experts expect high implied volatility from the start due to no positioning history, no IV anchor, and no established gamma exposure profile. SpotGamma noted the setup represents "one of the highest-gamma-sensitivity environments of the decade." The tradable float for SpaceX is just 3% to 5% of the company's valuation, creating a thin liquidity cushion. If retail call-buying dominates early flow, dealers will likely be short gamma, meaning their hedging activity could amplify price moves rather than dampening them.

Zero Hedge predicted a possible gamma squeeze that could drive the price to $400 per share, surpassing Nvidia. "SPCX options start trading tomorrow: it could gamma squeeze to 400, surpassing NVDA," Zero Hedge wrote in a post on X.

Market Dynamics and Demand

Compounding the dynamic, an estimated $22 billion to $27 billion in forced mechanical index buying is expected from Nasdaq-100 and Russell trackers in the coming weeks. SpaceX's Nasdaq-100 fast-entry is expected 15 trading days post-IPO. Reuters reported that more than 115,000 options contracts on SpaceX were traded in the first ten minutes and 500,000 options contracts changed hands in the first hour, according to Trade Alert data.

Mike Purves, CEO of Tallbacken Capital Advisors, told CNBC that the stock has the total addressable market of a science fiction novel while the price-to-earnings-growth ratio of chips is the lowest it has been in the sector's history. He suggested the dynamic for upside calls in AI-related stocks would be magnified for SpaceX.

Exchange and Trading Activity

For exchanges, the moment is massive. Cboe and Nasdaq handled nearly 60% of all options volume last year and will host SpaceX options. Robinhood Markets, where options trading represents roughly a quarter of total revenue, could stand to benefit significantly. SpaceX is expected to climb immediately to the top of the most-actively-traded options list, potentially rivaling Tesla and Nvidia in daily contract volume.

SpaceX stock was up 11.44% at $214.53 at the time of publication Tuesday.

Space Exploration Technologies Corp's public debut has introduced a company with a roughly $2.5 trillion market capitalization, creating a complex portfolio construction challenge for ETF managers. The massive valuation forces fund managers to decide how to balance exposure to the dominant space company against the need for diversified thematic funds. This development fundamentally alters the landscape for space-themed ETFs, which previously relied on satellite operators and aerospace suppliers.

Christopher Gannatti, Global Head of Research at WisdomTree, noted that SpaceX's size is transformative for thematic ETF construction. The company dwarfs most other pure-play space businesses, creating a conflict between market capitalization-weighted models and diversification goals. Most thematic ETFs employ concentration caps to prevent single-stock dominance, complicating the inclusion of such a large entity.

Index Constraints and Caps

Many space-focused indexes utilize rules to prevent any single security from overwhelming the portfolio. Micah Walter-Range, co-index developer of the VettaFi Space Index tracked by the Procure Space ETF, indicated that SpaceX would face a functional cap of roughly 15% under the current methodology. These caps are designed to capture the breadth of the space economy, including competitors and complementary businesses.

The Free Float Factor

The immediate impact of SpaceX on benchmark indexes may be tempered by its free float. Dave Barron, Global Head of Index and ETFs at Legal & General Asset Management, explained that index providers typically use free-float market capitalization for weightings. He stated that the SpaceX free float is expected to be approximately 4% initially. This limited float means the company's actual representation in indexes could be significantly lower than its total market value suggests, creating a dilemma for managers seeking to satisfy investor demand for exposure.
