Markets

The biggest IPO in history is underwater. SpaceX just broke $135.

One month after the biggest IPO ever — $86 billion at a $1.77 trillion valuation — SPCX traded as low as $132.15 Wednesday, under the $135 the company sold shares at. Roughly $850 billion of peak value is gone, and every aftermarket buyer is underwater.

SpaceX fell as much as 2.9% to $132.15 on Wednesday — its first trip below the $135 IPO price since the June 12 debut. The largest offering in history, $86 billion raised at a $1.77 trillion valuation, more than triple Alibaba’s long-standing U.S. record, is officially underwater one month in.

The round trip was fast. SPCX popped 19% on day one to close at $161, ran nearly 50% across its first three sessions, then shed roughly a quarter of its value in the three sessions that followed. From the post-debut peak the stock is down about a third — call it $850 billion in market value, more than almost any other company on earth is worth in total. Tuesday it closed about a dollar above the offer price. Wednesday the floor gave way.

The tape is not the problem. On the same day SPCX broke, PayPal jumped double digits on the Stripe–Advent take-private bid, BlackRock gained 7% on record assets, and a soft wholesale-inflation print had buyers reaching for risk. Money is flowing — just not here. That points at the stock, not the market: an IPO priced for perfection, a month with no new catalyst to feed it, and a governance setup in which Elon Musk kept 42% of the shares and 82% of the voting power. Public buyers got the economics and none of the say.

Our take

The IPO price is the line insiders sold at. Below $135, every single aftermarket buyer is losing money, and that flips crowd psychology from fear of missing out to fear of being the exit liquidity. Nothing about the rockets changed in a month — the price of believing did. SpaceX now faces a discipline it has never met in 24 years as a private company: the quarterly earnings call, where “we’re going to Mars” has to coexist with “walk me through Starlink’s numbers.” How that first call lands will matter more than any launch this year.

There is a read-through for everyone else in the pipeline. Bankers spent the spring calling this the great reopening — the $53 billion PayPal bid landed this morning, and OpenAI listing chatter has been building for weeks. The window is still open. But SPCX just became the comp every issuer prices against, and the cautionary slide in every pitch deck: hype fills the book, then the book has to hold.
