SpaceX to land in your 401(k) no matter what. Michael Burry flags retirement savings are ‘exit liquidity’ for insiders

Elon Musk’s SpaceX confidentially filed for what could be the largest IPO in financial history on April 1, targeting a $1.75 trillion valuation and a raise of up to $75 billion — more than triple the record for the largest U.S. IPO, set by Alibaba in 2014 (1).
If the company lists on Nasdaq this June as expected, the stock could land in your retirement portfolio within weeks. And some of Wall Street’s loudest skeptics think that’s a problem.
That’s thanks to Nasdaq’s new “Fast Entry” rule, approved March 30, which slashes the index inclusion waiting period from three months to just 15 trading days for any newly listed company whose market cap ranks in the top 40 of the Nasdaq-100 (2). The rule also waives the existing requirement that at least 10% of shares be available for public trading (3).
SpaceX clears those hurdles by a wide margin. At $1.75 trillion, it would be a top-10 company from day one — meaning every ETF and index fund tracking the Nasdaq-100, including the roughly $400 billion Invesco QQQ (NASDAQ:QQQ), would be required to buy SpaceX shares almost immediately after the IPO, at whatever price the market dictates.
George Noble, a former Fidelity fund manager with more than four decades on Wall Street, called the proposal “the most SHAMELESS structural manipulation of a major index I’ve ever seen” in a viral Substack post in March. Michael Burry, the investor behind The Big Short, shared Noble’s critique with his more than one million followers on X, calling it a “must read” (4).
The concern: with a float potentially as low as 5%, that $1.75 trillion valuation translates to roughly $87.5 billion in publicly tradable stock. The full Nasdaq-100 ecosystem represents more than $1.4 trillion in exposure across ETFs, mutual funds and derivatives (5). The rules, Noble wrote, are “being rewritten to benefit IPO issuers and early-stage insiders.” When lockup periods expire 90 to 180 days later, insiders holding the vast majority of shares can sell into artificially supported passive demand.
“Your 401(k) is the exit liquidity,” he wrote (5).

The concentration risk could get worse: former Tesla president Jon McNeill has said there’s a better-than-50% chance Musk merges Tesla with SpaceX after the IPO, which would tie even more passive retirement money to a single Musk-controlled ticker.
He’s far from alone. Jason Zweig of the Wall Street Journal called the proposal “arbitrary, unfair and potentially risky” (6). Robin Wigglesworth of the Financial Times described it as “the biggest bagholder operation in history” (7).
The numbers aren’t reassuring. A Harvard study from 2025 examined a comparable fast-track inclusion rule for a different major index. They found prices spike at inclusion, then fall by as much as 10 percentage points in the months that follow. Issuers, meanwhile, raise 6% more capital because anticipated passive demand inflates the IPO price (8). The S&P 500, by contrast, requires a 12-month seasoning period.
In August 2023, Vietnamese EV maker VinFast (NASDAQ:VFS) listed on Nasdaq via SPAC with a float of roughly 1% of shares outstanding (9). Within two weeks, chaotic trading pushed its market cap to nearly $190 billion — ahead of Goldman Sachs and Boeing on paper — despite quarterly revenue of just $65 million and losses approaching $600 million per quarter (10). Anyone who bought near the peak paid around $82 per share. It now trades around $4 (11).
Under Nasdaq’s new Fast Entry rule, VinFast’s inflated market cap would have qualified it for fast-track inclusion. Index funds would have been forced to buy in at a price that was, by almost any measure, meaningless.
No one’s arguing SpaceX shouldn’t go public. The argument is whether rushing the largest IPO in history into the most widely tracked indexes on Wall Street — before the market has had any real time to discover a fair price — is good for the millions of ordinary investors whose retirement savings will foot the bill.
