Michael Burry Says SpaceX Is Wildly Overvalued

The legendary "Big Short" short-seller is tearing into the market's historic $3 trillion public debut. Yet his ultimate refusal to execute the trade highlights a warning on market euphoria.

The Architecture of an Overinflated Listing

Michael Burry, the iconoclastic asset allocator made famous by The Big Short for predicting the 2008 residential credit collapse, has fixed his characteristically skeptical lens on the most expensive stock on earth. In a pointed note to clients, he heavily criticized SpaceX’s post-IPO valuation, which has ballooned to nearly $3 trillion within days of its public market listing. Yet despite diagnosing what he views as a glaring fundamental disconnect, the world's most famous contrarian is choosing to sit completely on the sidelines. Investors worldwide are scrambling for an answer to one core question: if the stock is as overextended as the data suggests, why won't its chief critic pull the trigger?

That makes this more than a routine valuation debate under the Wall Street spotlight.

Burry's qualitative assessment of the stock was unsparing. He characterized SpaceX as "fundamentally a small space company, a niche telecom, a bedeviled social media company, and a Coreweave-light" operating with an underlying annual revenue base of less than $20 billion. To demonstrate the scale of the anomaly, he highlighted that the company's roughly $2.8 trillion market cap now eclipses Warren Buffett’s Berkshire Hathaway by multiples, asserting its absolute price has completely detached from operational reality. The sheer velocity of the listing's momentum remains a foregone conclusion.

Then came the stark realization of how dangerous structural options pricing has made it to bet against retail euphoria.

An aggressive focus on premium protection has completely flipped the script, proving that high implied volatility has effectively weaponized derivatives against short sellers, forcing even the most hardened bears to retreat.

Why it matters

A historic $75 billion capital raise made SpaceX's listing the largest initial public offering on record, forever reshaping Big Tech dominance.
A 50% post-IPO surge pushed the stock from its initial $135 offering price to hover near the $212 mark within days of trading.
Expensive bearish options are keeping skeptics at bay, with December 2028 $100 strike puts commanding an incredibly steep $25 per contract premium.
A "neither short nor long" position was formally confirmed by Burry, validating that he is refraining from wagering any active capital on his thesis.
An under-$20 billion revenue baseline sits at the heart of the short case, throwing the firm's multitrillion-dollar enterprise valuation into sharp contrast.

What the market is pricing

Equity derivative networks have completely priced out normal valuation gravity for the remainder of 2026, leaning instead toward an environment driven by high retail call-option volumes and index inclusion dynamics. That matters because institutional desks spent weeks expecting the massive supply of new shares to drain broader market liquidity. Today's shifting environment suggests the market is actively discounting fundamental earnings metrics, relying instead on the unique appeal of Starlink's connectivity scale and deep commercial launch dominance.

The key question is not how high SpaceX trades this week. It is whether the underlying cost of capital will eventually force options market premiums to normalize.

Wall Street expects momentum buyers to drive the stock higher in the near term, but the long-term execution of Burry's broader bubble thesis is up for grabs. He recently issued a wider warning urging asset allocators to "reject greed," drawing explicit parallels between the current artificial intelligence-driven tech frenzy and the final, frothy phases of the late-1990s dot-com collapse. The internal friction of waiting out a speculative mania is highly complex, and the market's structural positioning is more volatile than it has been in decades.

The risk is that short sellers who try to time the top are systematically crushed by structural gamma squeezes before the fundamentals catch up. It may be a harsh reality check for legacy value investors expecting old-school valuation metrics to govern new-era tech listings.

Why this short thesis is different

The legacy short-selling playbook has followed a predictable routine for decades: identify an overvalued asset, construct a synthetic short via options or direct equity borrows, weather the short-term mark-to-market pain, and collect on the eventual crash. Macro traders learned to view Burry as a patient allocator willing to pay premium bleed to prove a point.

What changed this season is the sheer cost of structural insurance in the modern market architecture. Today's options prices collide directly with an absolute frenzy for long calls, driving implied volatility to a level where the math of a short trade fundamentally breaks down.

Furthermore, the timing of the SpaceX listing forces macro bears to step aside right as its market cap passes retail heavyweights like Amazon, leaving it trailing only a select handful of global technology titans.

The cost-of-carry and risk problem

The historic reliance on cheap derivatives structures pushed modern speculative shorts to rely heavily on long-dated put contracts. While straightforward corporate mispricings offer clean execution, a hyper-volatile momentum monster that prints premium costs of $6.75 for a short-term December 2026 contract can easily exhaust a fund's capital reserves long before the underlying bubble bursts.

A genuine failure to cool down the current retail hype cycle could keep the stock elevated indefinitely, but it won't invalidate Burry's warning that structural prices are sitting in dangerous territory.

That is the connection between a tactical Substack commentary and the trading desks of modern hedge funds. Burry’s structural reluctance flows directly into financial reality. A hyper-expensive derivatives board gives him the rare luxury of a strategic pause: treating his refusal to short as an educational warning on market mechanics rather than a financial defeat.

What to watch

The December 2026 options curve. Monitor the implied volatility metrics on the shorter-dated puts to see if premiums drop low enough to entice institutional bears back into the market.
The 15-day index inclusion window. Keep a close eye on structural fund flows as passive Nasdaq index trackers are forced to adjust their portfolios to accommodate SPCX.
Starlink's quarterly margin trajectory. Watch whether upcoming cash flow disclosures match the multitrillion-dollar valuation or validate Burry's "niche telecom" description.

The bottom line

Markets have been pricing in absolute certainty for SpaceX as an untouchable mega-cap growth engine. Today, the long-term look shows a highly sophisticated warning from one of history's most patient short-sellers.

The financial world has been waiting to see if a prominent bear would step forward to fight the post-IPO mania. This week, Burry's calculus confirms that betting against sheer market euphoria has become a premium-destroying trap. It is a lesson in risk management that Wall Street hasn't quite seen articulated at this tier before.

The underlying options contracts haven't cheapened yet. Whether the market's structural machinery forces a dramatic normalization this summer is the question the entire business world is waiting to see answered.
