SPCX Perp Eases to a 32% Premium as SpaceX's Record IPO Hits the Tape

Off the High, Still 32% Rich

The SPCX perp ran to $182.80 earlier this morning, about a 35% premium to the $135 offer, and has since eased to $178.20, up 9.85% over the past 22 hours. At $178.20 the contract still carries a roughly 32% premium and implies a valuation near $2.3 trillion, well above the ~$1.75 trillion SpaceX struck at the offer.

This is the run into the debut. The perp launched in mid-May near $150 and spiked above $216 in its first 24 hours — a >$2.5 trillion implied valuation — then compressed into the $160–170 range by June 8 before climbing back as the listing approached. The pullback from $182.80 is the first sign of the premium starting to ease now that real price discovery on the tape is close. Until the cross prints, the perp is the only continuously-traded mark on SpaceX, and CNBC flagged that perps point to a double-digit first-day pop.

The Biggest IPO Ever, and a 30% Retail Carve-Out

SpaceX priced its IPO at $135 a share on the evening of June 11, selling 555,555,555 shares to raise about $75 billion at a roughly $1.75 trillion valuation — the largest IPO on record, surpassing Saudi Aramco's 2019 debut. Underwriters hold a 30-day greenshoe option for an additional 83.3 million shares.

What makes this one unusual is the retail tilt. SpaceX reserved up to 30% of the deal for retail investors, against the typical 5–10%, and demand was extraordinary: total orders reportedly topped $250 billion, with retail alone above $100 billion, leaving the book roughly 3.5–4x oversubscribed. That supply-demand imbalance is exactly what a first-day pop is built from, and it is why the perp has held a double-digit premium into the open instead of converging back toward $135.

Whether the Perp Converges to the Cross

The bull case for the premium is the perp's own track record. When Cerebras listed, Hyperliquid's CBRS perp traded within about 1.3% of its eventual $350 Nasdaq open in the final hour, versus spreads near 35% on traditional pre-IPO platforms. If SPCX behaves the same way, $178.20 is a credible read on where the cross prints rather than noise.

The skeptical read: the grey-market secondary changed hands around $129–$137, far below the perp, so $178.20 is a bet on a retail-driven opening pop, not the institutional mark. And the contract carries its own tail risk — a May 28 oracle error flash-crashed the perp roughly 45% in 30 minutes, a reminder that thin books and oracle dependency can move this market on mechanics, not fundamentals. From here it is a convergence trade: once real shares trade, the perp marks against the tape, and the ~32% premium either gets confirmed or bleeds out.
