SPCX Steadies Near $158 as Short Sellers Build Against a Thin Float

No New Headline, Just New Shorts

SPCX is down 4.06% over the last 23 hours to $157.60, and there is no discrete catalyst behind this specific move. The honest read is that the post-IPO air is still leaking out. The stock opened at $150 on June 12 and ran to roughly $225 by June 16, then gave back about 16% in a single session on June 22 and briefly traded below its $150 debut on June 23 before bouncing. At $158 it is still roughly 30% off the high and only a few dollars above where it started.

The freshest legible input is positioning, not news: Reuters reports that short-selling bets against SpaceX have increased since the post-debut selloff began. That is the tell. This is not fundamental deterioration. It is a market that finally has the tools to fade a stock that priced in a decade of execution over four trading days.

The Float Is the Whole Story

SpaceX went public with roughly a 4% float, among the smallest for a mega-cap debut on record. A thin float cuts both ways: it manufactured the violent move up to $225, and it makes the move down just as sharp. With so few shares actually changing hands, every marginal seller drags the tape.

Until listed options began trading shortly after the IPO, there was no liquid way to bet against the name, which artificially suppressed short interest. Once derivatives went live, the bearish view had somewhere to go, and it is now showing up in the short-interest data. The mechanics matter more than any single headline here: a structurally shortable stock with almost no real float will keep trading violently in both directions until the supply picture normalizes.

The Setup Into August

Two things run underneath the price action, and neither is bearish on its own. On the balance sheet, SpaceX launched a $20 billion investment-grade bond, its first ever, to refinance the bridge loan it took in March around the xAI merger; investment-grade ratings from all three agencies and roughly $100 billion in cash mean the debt is not the worry. On demand, its AI compute business is real: SpaceX just signed a $6.3 billion deal to lease Nvidia GB300 capacity to Reflection AI at its Memphis Colossus site, on top of existing Google and Anthropic commitments.

So the fight is over valuation and supply, not the company. The analyst split says it all: Oppenheimer sits at Outperform with a $250 target while Susquehanna opened coverage at Neutral with a $170 target and told buyers to wait for a better entry. The real event is the lockup schedule. The first major tranche unlocks around Q2 earnings in late July or August, with an early-release trigger if SPCX closes at or above $175.50 on five of ten trading days. That is when the 4% float starts to thicken, and when the current short thesis either gets confirmed or squeezed.
