SPCX Perp Runs to $204 as Index-Forced Buying Hits a Float With No Borrow

The Bid You Can't Fade

SpaceX priced its IPO at $135 on June 12, the largest in history, and closed the first session up about 19% near $161. Three days later the cash stock sits in the mid-$170s to $180 and the Hyperliquid perp has run to $204 — and the reason is mechanical, not a fresh headline. With roughly 3–5% of shares in public hands, index providers are racing to add a $1.75 trillion company that almost nobody can sell.

Nasdaq-100 fast-tracked SPCX on a roughly 15-trading-day timeline with low-float weighting multipliers, FTSE Russell relaxed its float threshold for a September/December add, and MSCI's Global Standard indexes pull it in around ten trading days post-listing. SpotGamma pegs the near-term forced buying at $22–27 billion, with QQQ and Russell funds having to sell pro-rata from Nvidia, Apple and Microsoft just to fund the purchase. When that much price-insensitive demand meets a sub-5% float, direction stops being a question.

Why the Perp Is Rich

The interesting part for perp traders isn't the direction — it's the basis. SPCX trades a double-digit premium on Hyperliquid versus the roughly $175–180 cash tape, and that gap is structural, not noise.

There's effectively no borrow on a 4% float, so the equity can't be shorted in size. Anyone who thinks $200-plus is rich has nowhere to express it in the cash market, so that view routes into the perp, and longs pay for it through funding. The perp becomes the only liquid venue where both sides of the SPCX trade actually exist — which is exactly why it can detach from spot and stay detached for as long as the forced bid runs. Read the premium as the cleanest available gauge of how much demand there is to fade a stock that can't be faded anywhere else.

The Other Side

None of this makes the valuation defensible. S&P Dow Jones rejected its own fast-track proposal on June 4, keeping SPCX out of the largest index pool until it clears a 12-month seasoning and GAAP-profitability test — and with a reported $4.28 billion Q1 GAAP loss, that's not close. So the much-hyped "index inclusion" is Nasdaq-100 and MSCI, not the S&P bid many assume. Morningstar puts fair value far below the tape, implying roughly 65% downside.

The real test arrives September 2, when SpaceX reports for the first time and Starlink subscriber growth, Starship cadence and xAI capex stop being narrative and start being numbers. Before that, the first scheduled supply is a December insider lockup expiry — the first event that could actually loosen the float. Until something adds sellable shares, the squeeze plumbing stays intact and the perp premium stays the most honest number on the screen.
