SpaceX’s Second Launch Abort in Four Days Rattles Its New Public Stock

SpaceX’s Falcon 9 rocket ignited, then shut itself down, aborting a Starlink launch at Vandenberg Space Force Base on Monday, the company’s second scrubbed rocket in four days. All nine Merlin engines fired and cut out in barely three seconds while the booster sat clamped to the pad, the kind of post ignition abort the Falcon 9 program has suffered only twice in more than two years.

This time the fallout reaches somewhere Falcon 9 failures never used to: a stock ticker. SpaceX shares, public for barely six weeks, were already sliding below their IPO price when Monday’s scrub hit, four days after a separate abort grounded the company’s Starship rocket in Texas. Two unrelated rockets, two aborts, one increasingly nervous shareholder base.

Hold-Down Clamps Do Their Job Again at Vandenberg

The flight computer called it at 11:18 a.m. ET, moments after the Merlin engines lit for the Starlink 17-39 mission. An anomaly in the engine startup sequence triggered an automatic shutdown, the safety response built to fire only in the few seconds between ignition and liftoff, the last moment the system can stop a rocket without catastrophic consequences.

SpaceX posted a brief statement on X shortly after, later reproduced by Spaceflight Now.

Standing down from today’s Starlink launch; vehicle and payload remain safe.

SpaceX said in the post, confirming the booster and its 24 Starlink V2 Mini satellites were undamaged. The vehicle was booster B1082, flying what would have been its 23rd mission, and the launch would have been the 85th Falcon 9 flight of 2026 and the 667th overall. Instead it joins a short list. The last comparable post ignition abort came on June 14, 2024, during a Starlink 10-2 attempt at Cape Canaveral, a rocket SpaceX’s own VP of launch, Kiko Dontchev, called a real issue requiring in depth hardware inspection at the time. That mission flew nine days later on a different booster.

SpaceX has not said whether B1082 needs the same treatment. The company announced the 24 satellite Starlink mission on its own account hours before the countdown reached zero. No standdown has been ordered, and SpaceX is aiming to try again Tuesday morning, in a window that opens at 10 a.m. EDT, 7 a.m. local California time.

A Month-Old Stock Meets Its Second Bad Week

None of this would have mattered to a balance sheet a year ago. SpaceX went public on the Nasdaq on June 12, pricing shares at $135 under the ticker SPCX and raising $85.7 billion including the underwriters’ option, the largest IPO on record, valuing the company above $1.75 trillion.

The stock did what hot IPOs do, at first. Shares climbed as high as $225.64 within days before momentum reversed. By Wednesday, July 15, SPCX briefly dipped below its $135 offering price for the first time. Then came Thursday’s Starship abort, and shares fell more than 3% to close at $131.11, a fifth straight losing session. They kept sliding into the weekend, closing Friday around $127. By Monday, the day of the Falcon 9 scrub, shares had fallen below $124 and were still down about 1% by early afternoon.

A German markets wire covering both events together described SpaceX shares as nearing a 52 week low, with a lock-up expiration looming and analysts split on where the stock goes from here.

Merlins and Raptors Now Move the Same Stock Price

Falcon 9 and Starship do not share much beyond a logo. One is a 16 year old workhorse; the other is still proving it can fly a clean test profile.

SpaceX had already pulled two Raptor engines for replacement before Thursday’s rescheduled attempt, aiming to fly a booster that can complete stage separation, an in-space reignition test and deployment of 20 Starlink V3 satellites, too large for any Falcon 9 to carry. Wall Street is watching that flight closely, since JPMorgan analyst Seth Seifman told clients ahead of the scrub that he expects both progress and setbacks as SpaceX scales toward launching Starship dozens of times next year and thousands eventually.

Short Sellers and Cathie Wood Are Fighting Over the Dip

The stock’s second bad week has hardened two opposing bets. Institutional skeptics are circling. Enthusiast buyers are doubling down. Prediction markets are pricing the outcome in real time.

• Piper Sandler initiated coverage at Neutral, citing valuation and looming lock-up expirations on a float where only around 4% of shares currently trade.
• Short sellers have built a bear position reportedly worth roughly $25 billion against the stock.
• ARK Invest, Cathie Wood’s fund group, bought 122,807 SPCX shares worth about $16.6 million in a single session, part of a buying spree that topped $36 million in one week.

Prediction platform Polymarket, meanwhile, priced a 92% chance Starship flies by the end of July and 98% odds by the end of August. Separately, ahead of Thursday’s scrubbed attempt, the same traders gave 83% odds that the Super Heavy booster explodes, a market whose rules count even a planned, controlled destruction. Zacks currently rates the stock a Hold. SpaceX’s stock first slid below its IPO floor on the earlier Starship scrub, and every session since has added a new data point to that argument.

Golden Dome’s Fine Print

Wall Street is not the only party with new skin in this game. The Pentagon has quietly made SpaceX central to Golden Dome, the national missile defense architecture, and that dependency runs straight through Vandenberg’s launch pads.

In a four day window in May, Space Systems Command awarded SpaceX a combined $6.45 billion in Golden Dome related work, including a $2.29 billion contract for a Space Data Network Backbone and a roughly $4 billion award to build a space based surveillance constellation, according to reporting on the contracts. That work feeds the Space Development Agency’s Proliferated Warfighter Space Architecture (PWSA), the satellite mesh meant to relay missile tracking data to interceptors in seconds.

A single delayed Starlink mission does not threaten that timeline on its own. SpaceX’s Starlink constellation itself now numbers more than 10,800 functioning satellites, roughly 65% of all active satellites from any operator in orbit, and the company has said a one to two week delay from Monday’s abort will not affect coverage for current subscribers. Neither the Space Development Agency nor the National Security Space Launch program had publicly commented on the Vandenberg abort by Monday afternoon. A prolonged standdown, rather than a single missed mission, is the scenario that would actually worry the Pentagon’s planners.

Two Launch Windows Open Within Three Days

Two clocks are now running at once, one for engineers and one for shareholders.

• Falcon 9 gets another shot at Vandenberg Tuesday morning, in a window that opens at 10 a.m. EDT and runs nearly four hours.
• Starship’s 13th test flight is rescheduled for Thursday evening at Starbase, after the Raptor swap.
• SpaceX is due to report its first quarterly earnings as a public company in early August.
• Roughly 1.2 billion additional shares become free to trade around that same August lock-up expiration.

A clean flight on either vehicle this week would go a long way toward calming a stock that has now had a rough test flight and a rare pad abort inside the same seven days. The last time a Falcon 9 aborted like this, in June 2024, the rocket flew nine days later on a different booster. SpaceX has not said if B1082 will need the same fate.

Frequently Asked Questions

What caused the Falcon 9 abort at Vandenberg?

SpaceX’s flight computer detected an anomaly in the engine startup sequence and automatically shut down all nine Merlin engines about three seconds after ignition, before the hold-down clamps released the rocket. The Merlin 1D engines ignite using TEA-TEB, a pyrophoric fluid that bursts into flame on contact with oxygen, and the system is designed to abort if that ignition flame or pressure reading falls outside its expected range. SpaceX has not disclosed the specific trigger for Monday’s shutdown.

Is SpaceX publicly traded, and what is its ticker symbol?

Yes. SpaceX began trading on the Nasdaq on June 12, 2026, under the ticker SPCX, after pricing its initial public offering at $135 a share. Shares opened around $150 on the first trading day and climbed intraday to $225.64 within days, before giving back most of those gains over the following month.

When is the next Falcon 9 launch attempt after the abort?

SpaceX is targeting Tuesday morning at Vandenberg Space Force Base, with a launch window opening at 10 a.m. EDT (7 a.m. local California time) and running for nearly four hours. The rocket will carry the same 24 Starlink V2 Mini satellites that were aboard Monday’s scrubbed attempt.

What is the Golden Dome missile defense program?

Golden Dome is a large scale U.S. missile defense initiative that relies on a layered network of satellites to detect, track and help intercept incoming missiles. SpaceX builds part of the space based data relay and surveillance layers supporting the program, alongside contractors like L3Harris and Sierra Space, through Space Force contracts awarded in 2026.

Will the delay affect Starlink internet service for existing customers?

No. SpaceX says the constellation, which now numbers more than 10,800 functioning satellites, continues operating normally, and a one to two week delay in adding the next batch of satellites will not change coverage or capacity for current subscribers.
