SpaceX goes public, 12 June 2026: the red carpet…

On Friday 12 June 2026, Space Exploration Technologies Corp. takes its first steps on the Nasdaq under the ticker SPCX. A fixed price of $135 a share, about 556 million shares, $75bn raised, a valuation of $1,750bn. This is, by a wide margin, the largest initial public offering ever completed, more than double the record set by Saudi Aramco in 2019, according to Reuters. The staging is grand. The regulatory machinery that made it possible, far less flattering.

An accelerated review and a take-it-or-leave-it price

SpaceX filed its confidential S-1 on 1 April 2026, then its public version on EDGAR on 20 May (registration 333-296070). Between the two, the SEC wrapped up its review faster than expected, which allowed the calendar to be brought forward from an offering initially set for late June, according to three sources cited by Reuters. For the heaviest listing in the US equity market, the express handling raises questions.

Two structural anomalies accompany this favourable treatment. First, SpaceX set a single price of $135, take it or leave it, instead of the indicative range that moves with demand, as convention dictates. Second, up to 30 percent of the offer, about $22.5bn, is reserved for retail, against 5 to 10 percent normally. Ordinary savers are thus exposed, en masse, to the most opaque and most expensive listing on the market.

Then there is the index question. The inclusion of SPCX in the major indices, and the tens of billions of forced buying that come with it, turns a speculative bet into an imposed exposure for millions of passive fund holders. S&P Global declined to play along as things stand, but the mechanism remains explosive.

A moonshot S-1

The prospectus itself is worth the detour. In it, SpaceX promises AI compute satellites in sun-synchronous orbit, meant to process inference at a scale beyond terrestrial data centres, with a first deployment announced as early as 2028. The syndicate banks project $140bn of Starlink revenue in 2030. The $1,750bn valuation, as Elizabeth Warren writes, demands many acts of faith.

Above all, what investors are being asked to value is no longer the profitable space company we knew. In February 2026, SpaceX absorbed xAI, Musk’s AI company, renamed internally. Consolidated result: a loss of about $5bn over 2025, of which nearly $4.94bn is directly tied to the xAI merger, and a cash burn on the order of $1bn a month (Investing.com, Yahoo Finance). The Space and Connectivity segments remain profitable. The cash furnace is AI, consolidated by force into a single vehicle rather than isolating the mature activities, as management had nonetheless hinted. All of this against a backdrop of political frenzy around AI, the one where a phrase promising “the American people as shareholders of AI” moved semiconductors by tens of billions.

Warren rings the alarm

On 9 June, Elizabeth Warren, the ranking Democrat on the Senate Banking Committee, sent a twelve-page letter to SEC chair Paul Atkins. In it she asks that the listing be delayed until investors are protected. Her grievances: potentially misleading accounting around the xAI acquisition, Musk’s uniquely unchecked power through a multiple-voting-rights structure, and rigged stock indices that would force millions of savers to hold SpaceX without having chosen to. Her formula sums up the affair: major risks for small holders, enormous advantages for insiders. At the time of listing, neither SpaceX nor the SEC had responded on the substance.

The financial risks, unvarnished

The work of Jay Ritter (University of Florida) has been a reminder for decades: the best very large IPOs underperform the S&P 500 in the years that follow. SpaceX may be the exception, but the base rate is not flattering. Add a float estimated between 3 and 5 percent, which amplifies volatility, lock-up periods that release paper later, conflicts of interest between Musk entities (Tesla, xAI, SpaceX), and an overweight retail base quick to sell if the first session disappoints. The cocktail is a known one.

And that huge short position

On the synthetic side, the show has already begun. With no shares available before the bell, pre-IPO perpetuals on SPCX have been trading since mid-May (Hyperliquid, Kraken up to 5x), where you can be long or short on a price, not on the company. Arkham Intelligence flagged precisely a $5.7m short position at 2x leverage opened by an account under the pseudonym wenyu8888888, which it describes as the largest SpaceX short it has tracked. The thesis is clear: the IPO premium will deflate once the public listing is under way. Facing it, Arkham and Onchain Lens spotted a record long of $16.6m posted by address 0x9cc. A useful reminder: these perpetuals never become shares, they only track the price.

The red carpet is rolled out, the rules softened, the S-1 cosmic. Good luck to investors. Good luck to traders.
