SpaceX IPO May Test Liquidity in U.S. Stock Rally

The S&P 500 surpassed 7,400 for the first time. Over the past 12 months the index is roughly 27% higher. The Nasdaq-100 is up about 40% year-over-year, and April 2026 posted the strongest monthly gain in 23 years.

Gains have been concentrated. In one session five mega-cap stocks accounted for roughly three quarters of the S&P 500’s advance. Memory and semiconductor stocks tied to artificial intelligence have seen large moves: SanDisk is up more than 510% year-to-date and nearly 4,000% since its 2025 spinoff; Western Digital is about 190% higher year-to-date; Micron is up about 170% year-to-date.

Options activity shows different patterns at the single-stock and index levels. Cboe data report single-stock call volume at 3,695,561 contracts and put volume at 1,954,735, a put/call ratio of 0.53. At the same time, SPY options logged about 4,030,087 call contracts and 5,271,270 put contracts, a put/call ratio near 1.31; QQQ shows a similar put-heavy split at about 1.32. Single-stock options have more call activity while major ETF options show heavier put activity.

Market participants note how dealer hedging can affect prices. When investors buy call options, dealers often sell the calls and hedge by purchasing the underlying shares, which can push stock prices higher. If prices stop rising and those call positions lose value, dealers can reduce hedges by selling shares, which can add downward pressure.

SpaceX is under discussion for a possible IPO in summer 2026, with early valuation talk reaching into the trillions. Market commentary highlights that a large, heavily subscribed offering would absorb a substantial amount of market liquidity.

Crypto markets experienced a major deleveraging in October 2025 when roughly $19 billion in leveraged positions were liquidated within about 24 hours. Crypto prices have not matched their prior peaks while U.S. equity indexes continued to new highs.

Analysts outline two timing scenarios for when pressure on markets might appear. In the first, a liquidity drain in early-to-mid summer 2026 would coincide with a SpaceX listing and with Bitcoin moving toward an $84,000 CME futures gap. In the second, political dynamics around the U.S. November 2026 midterm elections could keep risk appetite elevated through the summer and postpone an unwind until after the vote.

Both scenarios describe a period when leverage in equities and crypto would reset. Observers identify liquidity as a central market risk distinct from headline volatility, and note that Bitcoin’s 24-hour trading and higher beta mean it may respond earlier to stress than traditional equity markets.
