Update (September 28, 2026): Flight 14 flew on September 28. SpaceX reports that Starship reached orbit for the first time, deployed 26 Starlink V3 satellites and splashed down in the Pacific after about 3 hours in orbit, and that the Super Heavy booster splashed down in the Gulf. No catch of either stage was planned or made. The price scenarios this article originally carried were written before the flight and have since been removed. See our Flight 14 report.

Update (September 24, 2026): Since this was written, SpaceX published its plan for Starship Flight 14. It was the first planned orbital flight of Starship (all 13 flights to that date, including Flight 13, were suborbital), then targeted for no earlier than September 28, 2026, pending FAA approval, and it was to deploy 26 Starlink V3 satellites. No ship catch was among its published objectives, and its booster was to land offshore. The late-August target mentioned below was never a SpaceX date. See our Flight 14 preview and the Starship tracker.

Two months ago, on June 12, 2026, SpaceX priced the largest initial public offering in history: $135 per share, roughly $75 billion raised, at a valuation of about $1.78 trillion. In our pre-IPO analysis in March, we asked whether a trillion-dollar-plus valuation was defensible. The market has now spent two months answering: loudly, and in both directions.

In mid-August SPCX traded at $140, a market capitalization of $1.84 trillion (SpaceNexus market data, synced August 15). That single number hides one of the most dramatic trading stories of the year: a euphoric debut, a spike, a grinding six-week retracement that briefly took the stock below its IPO price, and a sharp August recovery. Using the daily price history from our Space Stocks tracker, here is what actually happened, and what to watch for the rest of 2026.

The Real Trajectory: Pop, Spike, Slide, Rebound

The headline arc ("debuted near $2.1 trillion, now $1.84 trillion") makes it sound like a gentle drift. The daily chart tells a rougher story, in four phases:

Phase 1: The pop (June 12)

Priced at $135, SPCX closed its first session at $160.95, up 19% on the day, for a debut-day market cap of roughly $2.1 trillion, instantly one of the most valuable companies on Earth, eclipsing Saudi Aramco's 2019 debut as the largest listing ever.

Phase 2: The spike (mid-June)

In the frenzied first weeks of trading, shares ran far above the debut close, touching an intraday high of $225.64, which, at the current share count, would have implied nearly $3 trillion of market value. That level lasted moments, not weeks, and stands as the stock's post-IPO high-water mark.

Phase 3: The slide (July)

Then came the retracement. From a July 6 close of $160.42, SPCX fell in almost a straight line for the rest of the month: $145 by July 10, $124 by July 17, and a July 31 close of $108.37. The closing low came on August 5 at $108.27, with an intraday low of $104.83. Peak to trough, that is a decline of more than 50% from the June spike, about 33% below the first-day close, and, notably, about 20% below the $135 IPO price itself.

One honest observation from the data: Starship Flight 13's successful suborbital test on July 24 did not stop the slide. SPCX closed at $115.07 that day and kept falling for another week. Whatever was driving the July selling (profit-taking from the spike, valuation discipline, early-holder positioning ahead of future share supply), it was bigger than one good flight.

Phase 4: The rebound (August)

The turn came in early August, and it was violent. From the August 5 closing low of $108.27, the stock jumped to $133.11 on August 7, a 16% single-day move, and ran to a rebound high of $146.15 on August 12, a 35% recovery in five sessions. It has since settled to $141.29 (August 13) and $140.00 (August 14). We won't pretend our data can cleanly attribute daily moves to specific headlines.

Net of all the drama: SPCX is up about 4% from its IPO price, down about 13% from its first-day close, and down about 38% from its speculative June high. For a two-month-old mega-cap listing, that is neither triumph nor disaster: it is a market groping toward a fair price for something it has never had to price before.

What Drove It: The Fundamental Backdrop

Price action aside, the underlying news flow during SPCX's first two months has been mostly constructive.

Starship's best test flight yet, and Flight 14

Flight 13 on July 24 was the program's cleanest ship flight yet, though still a suborbital test: Starship released its first 20 real Starlink V3 satellites on a suborbital path (they reentered by design) and made a soft splashdown, coming to rest intact in the Indian Ocean, while the booster made a hard splashdown in the Gulf. Flight 14, then reported for as early as late August, was the next flight; after Flight 13, Elon Musk said SpaceX would try to catch the ship with the tower on the next flight, the gating step toward full, rapid reusability of both stages (SpaceX's later Flight 14 plan does not include a ship catch; see the update above). Follow the campaign live on our Starship tracker. For SPCX, Starship cadence is the single most watchable operational metric: it drives Starlink V3 deployment economics, Artemis obligations, and the long-duration Mars narrative that underpins the valuation's outer years.

Starlink economics carry the valuation

Starlink remains the revenue engine of the business. SpaceX's S-1 (May 20, 2026) gave the first audited figures: $18.7 billion of revenue in 2025, of which the Starlink-driven Connectivity segment was $11.4 billion, with 8.9 million Starlink subscribers at the end of 2025 and a net loss of $4.9 billion for the year (Via Satellite). How those numbers develop in SpaceX's quarterly reports as a public company is the fundamental question of H2.

The defense relationship deepened, with a twist

On August 13, the Space Force awarded $60 million to five companies (Amazon Leo, Lockheed Martin, Northrop Grumman, Rocket Lab, and York Space) to prototype and test connections to the SpaceX-built data network backbone (SpaceNews, via our news feed). Read that carefully: the dollars are trivial for a $1.8 trillion company, and they went to other vendors. The signal is double-edged. On one hand, SpaceX's network is literally the backbone the Pentagon is building around: a remarkable position of infrastructure entrenchment. On the other, the Space Force is deliberately cultivating a multi-vendor ecosystem on top of it, a reminder that procurement diversification is policy and that no incumbent's share of military space spending is guaranteed to grow unchecked.

Artemis obligations are on the clock

Under NASA's February 2026 restructure, Artemis III is now a crewed Earth-orbit docking test with Starship HLS and Blue Moon pathfinders, which NASA plans for 2027 (the NASA Administrator spoke of a summer 2027 launch on 23 Oct 2026), with the first crewed lunar landing moving to Artemis IV in 2028. SpaceX's HLS contracts covered the landings then planned for Artemis III and IV, but NASA now says lander readiness will decide whether Starship or Blue Origin's Blue Moon flies the Artemis IV crew. H2 2026 progress on HLS hardware, propellant-transfer testing, and the demo timeline feeds directly into how the market handicaps SpaceX's highest-profile government program.

Valuation Context: What $1.84 Trillion Assumes

On the S-1's 2025 revenue of $18.7 billion, SPCX at $1.84 trillion was valued at about 99 times trailing revenue (our arithmetic: $1,844 billion divided by $18.67 billion).

For scale: SPCX's $1.84 trillion is roughly 36 times the market cap of Rocket Lab (~$51B), the second-most-valuable publicly traded pure-play space company. Our side-by-side SPCX vs. RKLB comparison breaks down how differently the market prices the two business models. And for how SpaceX's listing reshaped the whole sector's capital structure, see our new Top 50 Space Companies for H2 2026.

What to Watch in H2 2026

Nobody, including us, knows where SPCX trades in December, and SpaceNexus does not publish price targets. Four things dominate the second half:

• Starship Flight 14 (then reported as NET late August; flew September 28): the first Starship to reach orbit, SpaceX reports.
• Starlink disclosures: subscriber, revenue, and margin numbers in SpaceX's early public reporting.
• Artemis milestones: HLS demo progress against NASA's Artemis III timeline (2027; the NASA Administrator spoke of a summer 2027 launch on 23 Oct 2026).
• Lock-up releases: SpaceX's S-1 set out a staggered, tiered lock-up rather than a single 180-day lock-up, with release dates tied to earnings milestones and fixed time intervals (Baillie Gifford's summary of the filing), so insider and employee shares become sellable in stages.

Note (October 2026): this section originally set out bull, base and bear price scenarios tied to the outcome of Starship Flight 14. Flight 14 has since flown (see the update at the top), and we have removed the price scenarios: SpaceNexus does not publish price forecasts for any security.

How to Follow It

A final word on process. The most common mistake with a stock like this is narrative-fitting: deciding SPCX is "obviously" the next mega-cap compounder or "obviously" the next Aramco, then reading every headline as confirmation. The first two months argue for humility: the same company, with the same fundamentals, has been priced anywhere from $1.4 trillion to nearly $3 trillion since June. Watch the four items above and let the disclosed numbers, not the debut euphoria or the July gloom, update your view.

We track SPCX daily (price, market cap, and 30-day chart) on Space Stocks, alongside every public space name. The SpaceX company profile carries the full corporate picture, and the Starship tracker has Flight 14's full record. However H2 resolves, the deeper point from our March analysis has already come true: space now has a public benchmark, priced in real time, and the entire industry's cost of capital moves with it.
