SpaceX’s path to a record IPO: a chronological account of milestones, setbacks and strategic shifts

From Falcon 1 to Starship and the acquisition of xAI, SpaceX’s public listing caps more than two decades of technical firsts, program failures and expanding ambitions

By Caleb Monroe

SpaceX filed publicly in May 2026 for what is expected to be the largest U.S. initial public offering ever, capping a multi-decade trajectory that moved commercial rocketry from experimental startup work to mainstream investment interest. The company’s history includes early launch failures and later firsts for private spaceflight, repeated tests and accidents with its Starship program, contracts and missions with NASA, deployment of the Starlink broadband constellation, and a large February 2026 acquisition that combined the company with an AI startup. This timeline lays out the key events recorded by SpaceX since its founding in 2002 through the public IPO filing in May 2026.

SpaceX’s path to a record IPO: a chronological account of milestones, setbacks and strategic shifts

Key Points

  • SpaceX’s public IPO filing in May 2026 follows a confidential filing in April 2026 and could become the largest U.S. listing in history - impacts capital markets and aerospace investing.
  • The company’s timeline includes early launch failures, later technical firsts for private spaceflight, and multiple high-profile Starship accidents - relevant to aerospace and defense sectors.
  • SpaceX expanded beyond launch services into global internet delivery via Starlink and into AI with the February 2026 xAI acquisition - affecting telecommunications and AI-related markets.

Overview

SpaceX, founded by Elon Musk in March 2002, publicly filed for a U.S. initial public offering in May 2026 after first confidentially preparing the paperwork in April 2026. The public filing transformed the company from a privately held enterprise focused on developing rockets and satellites into a candidate for what is expected to be the largest stock market flotation in history. The following timeline details major technical milestones, contractual wins, program failures and corporate moves that the company recorded on its way to the May 2026 IPO filing.

Timeline of notable events

  • March 2002 - Elon Musk launched SpaceX using money he made from the sale of PayPal.
  • March 2006 - SpaceX launched its first rocket, the Falcon 1, which failed.
  • September 2008 - Falcon 1 launched successfully for the first time and became the first privately developed liquid-fuel rocket to reach Earth orbit.
  • December 2008 - SpaceX secured its first major contract with NASA to ferry cargo and supplies to the International Space Station (ISS).
  • May 2012 - A Dragon capsule was taken to space by a SpaceX Falcon 9 rocket, becoming the first private spacecraft to dock at the ISS.
  • June 2015 - A Falcon 9 rocket exploded mid-air.
  • December 2015 - SpaceX achieved the first successful vertical landing of a Falcon 9 rocket, marking the first time a large rocket managed a controlled recovery after delivering a payload into orbit.
  • February 2018 - The first Falcon Heavy launch carried Musk’s Tesla Roadster and its mannequin driver, Starman, into space.
  • April 2019 - A Crew Dragon test vehicle capsule exploded during a ground test.
  • May 2019 - SpaceX began launching Starlink satellites, a constellation designed to beam high-speed internet signals to paying customers worldwide.
  • October 2020 - SpaceX completed its 100th successful flight of a Falcon rocket since Falcon 1 first reached orbit in 2008.
  • November 2020 - The Crew-1 mission flew, identified as the first operational mission under NASA’s Commercial Crew Program.
  • April 2021 - NASA awarded SpaceX the contract for the first commercial human lander on the moon as part of its Artemis program.
  • September 2021 - SpaceX launched the first all-civilian crew to circle the Earth.
  • November 2021 - NASA’s Double Asteroid Redirection Test (DART) mission launched into an interplanetary transfer orbit aboard a SpaceX rocket, marking the world’s first test of a planetary defense system designed to prevent a potential asteroid collision with Earth.
  • April 2023 - The first Starship rocket exploded after losing control.
  • November 2023 - A Starship launch failed minutes after reaching space.
  • November 2023 - A U.S. judge blocked the U.S. Department of Justice from pursuing an administrative case accusing Elon Musk’s SpaceX of illegally refusing to hire refugees and asylum recipients.
  • September 2024 - The SpaceX Polaris Dawn mission carried out its first privately managed spacewalk.
  • January 2025 - A SpaceX Starship rocket broke up in space minutes after launching from Texas, forcing airline flights over the Gulf of Mexico to alter course to avoid falling debris.
  • June 2025 - Starship exploded during a ground test.
  • February 2026 - SpaceX acquired Elon Musk’s artificial-intelligence startup xAI in a deal worth $250 billion, unifying Musk’s AI and space ambitions by combining the rocket-and-satellite company with the maker of the Grok chatbot.
  • February 2026 - SpaceX shifted its focus to building a "self-growing city" on the moon, Musk said.
  • March 2026 - A NASA official said the Starship has accumulated at least two years of development delays since NASA selected the rocket as an astronaut moon lander in 2021, and that it is expected to require more time to clear remaining hurdles before it can land on the moon.
  • April 2026 - SpaceX confidentially filed for its blockbuster U.S. initial public offering, laying groundwork for a potential record-setting listing.
  • May 2026 - SpaceX publicly filed for its long-awaited U.S. IPO, which is expected to become the largest listing in history.

Context and significance within the record

The sequence maps a company journey that includes technology demonstrations, commercial service rollouts and recurring technical setbacks with the Starship program. It also shows SpaceX expanding beyond rockets into satellite-delivered internet service and, via the February 2026 acquisition, into artificial intelligence technologies linked to Musk’s Grok chatbot. The public IPO filing in May 2026 formalizes the company’s intention to enter public equity markets after a period of confidential preparation the month before.

Risks

  • Repeated setbacks and accidents in the Starship program, including explosions and in-flight failures, create technological and schedule uncertainty - impacts aerospace and commercial space services.
  • A NASA official cited at least two years of development delays for Starship since 2021, indicating potential timeline and program risk for lunar lander ambitions - impacts government contracts and lunar mission schedules.
  • Legal and regulatory uncertainty following the November 2023 judicial block on a DOJ administrative action alleging hiring discrimination could affect corporate governance and regulatory scrutiny - impacts corporate legal and compliance considerations.
