The Lockup That Didn't Break: SpaceX and the 2026 Issuance Wave

When 911 million SpaceX shares became eligible to trade on August 6, the market braced for a flood. Instead, it got a rally.

SpaceX’s first post-IPO lockup expiry was supposed to be the day insiders ran for the exits. Nearly a billion shares—roughly 20% of the company—were freed from trading restrictions, more than doubling the public float overnight^[1]. The stock had already been hammered: shares fell nearly 14% the day before^[1], trading well below the $135 IPO price and down sharply from the brief post-debut high of $225^[1].

Then the bell rang. SpaceX opened 6.1% higher at $114.92^[1]. Over the next five trading sessions, the stock climbed 35% to $146.15, reclaiming its IPO price^[2]. As of midday August 13, SPCX trades around $140^[3]—down roughly 4% on the session but holding well above the lockup-day lows.

Why the flood never came

The explanation is less dramatic than the setup. For one, SpaceX had run semiannual internal buyback rounds for years before going public, giving employees periodic liquidity^[4]. “These are not people waiting to get their first dollar back,” a former employee told Fortune^[4]. There was no coordinated dash for the exits.

Second, the selling pressure was already absorbed. D.A. Davidson analyst Gil Luria noted the stock had fallen almost every day for three to four weeks ahead of the event^[4]. Hedge funds and event-driven traders had sold in anticipation, then covered their shorts once the lockup actually expired—the classic “sell the rumor, buy the news” pattern.

Third, institutional buyers were waiting. Tigress Financial Partners’ Ivan Feinseth described the unlock as “a largely technical event that accelerates the transition of ownership from insiders to a deeper, more stable public float”^[4]. Large funds that wanted to build positions preferred to wait for the liquidity event rather than buying incrementally and pushing prices against themselves.

The bigger picture: a record issuance year

SpaceX’s lockup was a single event, but it sits inside a much larger story. Federal Reserve data showed $389 billion in new equities hit the market in Q1 2026 alone—the largest quarterly issuance figure since the 2021 SPAC boom, and otherwise the highest on Fed records going back to 1996^[5].

Goldman Sachs Research calls 2026 a record year for US IPO issuance^[6], with the deal count expected to reach roughly 120 listings, nearly double 2025’s total^[7]. UBS puts IPO issuance on track for $200–350 billion^[7].

The natural question is whether this is a late-cycle warning sign—after all, the only comparable quarter was Q1 2000, when the dot-com boom peaked^[5]. Goldman’s answer is measured: the bank argues supply remains modest relative to the size of the equity market and that “record US equity issuance will not derail the bull market in 2026”^[5].

What’s driving the supply: AI capex meets equity markets

The engine behind the issuance wave is unmistakably AI. Goldman strategist Ben Snider attributes the surge in follow-on equity issuance to financing needs tied to AI investment^[8]. Follow-on issuance has risen to levels not seen since 2021^[8].

Hyperscalers—Alphabet, Amazon, Meta, Microsoft, and Oracle—are spending at rates that outrun their free cash flow^[9]. Oracle has indicated it will likely sell more stock next year, and Alphabet is planning large equity sales to fund AI infrastructure^[5]. U.S. corporations raised $252 billion through equity issuance^[9] as capex demands intensify.

This represents a structural reversal. For over two decades, the US equity market has shrunk as cash-rich companies—especially mega-cap tech—bought back shares, steadily reducing the supply of publicly traded stock. Bob Elliott of Unlimited Funds called the current shift “one of the biggest shifts in supply we have seen in some time”^[5]. Buybacks are slowing as capex takes priority; Goldman noted in May that AI spending is coming at the expense of share repurchases^[9].

The buyback counterweight

The bearish read is straightforward: if companies stop shrinking their share count and start issuing new equity, the supply-demand tailwind that supported the bull market reverses.

Goldman’s counterargument is that corporate demand for US equities will likely outstrip supply even with elevated issuance^[8]. The bank expects buybacks, combined with debt financing, to offset much of the incremental supply from AI-driven issuance. What would have to be true for that to hold? Buyback programs would need to remain robust even as capex climbs, and debt markets would need to stay open and accommodating.

There are early signs of strain. Opendoor, for instance, completed a 5% share buyback while simultaneously raising $440 million in growth capital at a 0% coupon^[8]—an unusual combination that signals companies are stretching to do both. Meanwhile, OPENLANE saw its stock drop 5.3% in premarket trading after a major shareholder, Apax Partners, launched an 8 million-share secondary offering; the company’s concurrent repurchase covered only $25 million of the offering^[8].

The AI IPO pipeline: Anthropic and OpenAI

The next test of market appetite is already visible. Anthropic has been meeting potential investors ahead of an IPO that could launch as early as September or October 2026^[10]. OpenAI confidentially filed for an IPO with the SEC in June, targeting a valuation of up to $1 trillion^[10].

But OpenAI’s timeline is less certain. CNBC reported that the company has not yet held pre-IPO meetings or set an official timeline, and The New York Times reported OpenAI is leaning toward delaying to 2027^[10]. Prediction-market traders on Kalshi now price an OpenAI IPO announcement by March 2027^[10].

The staggered timing matters. If Anthropic prices first, it sets the valuation benchmark for the AI sector. If OpenAI waits, it gambles on better conditions—and a higher price—next year. Either way, the market will need to absorb two of the largest IPOs on record within a compressed window.

Secondaries and the private-equity liquidity squeeze

Beyond IPOs, a quieter channel of supply is flowing. Secondary offerings are accelerating as private-equity firms seek exits. OPENLANE’s offering is a template: a PE sponsor (Apax Partners) converting preferred shares and selling 8 million shares into the market, with the company buying back only a fraction^[11].

More broadly, the secondary market—where investors buy and sell existing PE fund positions—is moving mainstream as the asset class grapples with a liquidity squeeze. Distributions have slowed and exits are harder to execute^[8]. This pressure creates a backlog of supply that could hit public markets through IPOs and secondaries for months.

What to watch next

1. SpaceX’s next lockup tranche. Reuters reports a staggered lockup schedule frees additional shares by mid-2027^[12]. Each tranche is a smaller test, but cumulative selling could weigh on the stock if fundamentals disappoint.

2. Anthropic’s IPO pricing. If Anthropic prices in September or October, the reception will set the tone for AI valuations broadly—and for OpenAI’s timing decision.

3. OpenAI’s timeline decision. A delay to 2027 would signal that even the most prominent AI company sees valuation risk in the current market. A 2026 listing would test whether demand can absorb multiple mega-deals simultaneously.

4. Hyperscaler equity issuance. Watch for follow-on offerings from Alphabet, Oracle, and others. The pace and size of these deals will reveal whether AI capex is a temporary financing need or a structural shift in equity supply.

5. Buyback announcements in Q3 earnings. If mega-cap tech companies trim repurchase authorization while boosting capex guidance, the buyback counterweight weakens.

The SpaceX lockup passed its first test. The broader issuance wave is just getting started—and the market’s ability to digest it will depend on whether the forces that absorbed a billion SpaceX shares hold up when the next billion arrive.
