SpaceX Accelerates Employee Vesting, Files IPO Prospectus Within Days at $350B Valuation

SpaceX moved up the vesting schedule for employee stock options and prepared to file its IPO prospectus this week, setting the stage for a public offering that could value the company at $350 billion and mark the largest U.S. tech debut since Rivian's $66.5 billion listing in November 2021. The accelerated vesting applies to options granted between 2020 and 2023, compressing what were typically four-year schedules into immediate liquidity events for roughly 12,000 employees across production, engineering, and flight operations. The move signals confidence in near-term pricing and removes a common pre-IPO friction point: employee lockup anxiety.

The prospectus filing, expected between Thursday and Monday according to two people familiar with the timeline, follows eighteen months of private secondary market activity that established SpaceX as the second-most-valuable private company in the world behind ByteDance. December 2024 tender offers cleared at $185 per share, a 28% premium to the June 2024 round. Starlink, the satellite internet subsidiary contributing $6.6 billion in annualized revenue as of Q4 2024, now operates 6,300 satellites and serves 4.2 million subscribers across 75 countries. That revenue figure has doubled year-over-year while Falcon 9 launch cadence hit 144 missions in 2024, a 22% increase from 2023. The company is cash-flow positive on a consolidated basis, a rarity among pre-IPO tech giants of the past decade.

The timing matters for three reasons. First, SpaceX enters the public market with $230 million in NASA contracts secured through 2027 and $1.8 billion in Defense Department launch commitments, de-risking revenue for institutional allocators. Second, the IPO window for high-growth infrastructure plays has reopened after sixteen months of dormancy; January 2025 saw $14.3 billion in U.S. tech offerings, the strongest start to a year since 2021. Third, Tesla shares rallied 4.7% on Wednesday following SpaceX IPO reports, suggesting crossover investors view the offering as a catalyst for Musk's broader portfolio rather than a distraction. Family offices have been circling SpaceX exposure for years without a clean entry point; the public float solves that.

Allocators should watch three follow-on events. The S-1 filing itself will clarify the Starlink carve-out structure—whether SpaceX lists the satellite business separately or keeps it consolidated—and reveal burn rates for Starship development, which consumed an estimated $2 billion in 2024. Roadshow timing likely lands in late February or early March, with pricing two to three weeks after that. Finally, employee lockup expirations, typically 180 days post-IPO, will hit in August or September, creating a natural test of retail conviction. Secondary market desks are already modeling 15-20% post-lockup dilution based on the accelerated vesting cohort.

The Defense Department awarded SpaceX a $733 million contract for Starshield military satellite launches on Tuesday, a detail buried in the noise but material for underwriters building the national security narrative into the prospectus.
