SpaceX Shares Settle in Mid-$150s After Record IPO as Traders Watch Short Bets and Lockups

The stock's early volatility now tests whether rapid index inclusion and upcoming insider unlocks will force big swings.

Overview

  • SpaceX completed its record‑setting IPO on June 12, 2026, pricing at $135 and raising roughly $75 billion with the underwriters' overallotment lifting total proceeds to about $86 billion.
  • Shares surged above $225 in initial sessions before falling back to the mid‑$150s, a swing driven by heavy retail trading, large options flows and profit‑taking that erased much of the post‑IPO gains.
  • Short interest has climbed to about 13% of the public tradable float while ARK Invest disclosed additional purchases, a mix that has strengthened both bearish positioning and squeeze talk among traders.
  • Management has rapidly shifted capital toward AI infrastructure—reported multi‑hundred‑million‑to‑billion‑dollar monthly contracts, an all‑stock purchase of Cursor and filings for a large notes offering—which investors say raises dilution and execution questions.
  • Structural mechanics that could worsen volatility include a very small initial public float, Nasdaq’s fast‑track index inclusion that will push passive buying, and a staggered lockup schedule that will meaningfully expand tradable shares in the weeks ahead.
