SpaceX's $116 Billion Lockup Test: Why August 6 Could Reshape the 2026 IPO Market

The US IPO market just had the biggest quarter in its history. It may be about to face the biggest test of whether that activity is sustainable.

Q2 2026 saw 48 IPOs raise a record-breaking $104.8 billion, led by SpaceX’s $75 billion offering — more than all US IPOs from the prior two calendar years combined.^[1] Even stripping out that single deal, nine other IPOs raised $1 billion or more, led by AI chipmaker Cerebras, making Q2 the strongest quarter for proceeds since 2021 without the headline transaction.^[1] Through July 10, operating companies had raised $140 billion in IPOs, 91% of it on Nasdaq — within $1 billion of matching 2021’s full-year record of $141 billion.^[2]

Yet the forward picture is less straightforward than the headline. The supply of newly tradable shares is about to increase dramatically, the AI infrastructure thesis that powered many of these deals is showing cracks, and the underlying plumbing of the equity market is thinner than it looks.

The August 6 Unlock: 911.5 Million Shares

SpaceX (SPCX) will report its first quarterly earnings as a public company on August 4.^[3] Two days later, on August 6, approximately 911.5 million shares — roughly 20% of locked-up stock — become eligible to trade, representing as much as $116 billion in market value at current prices.^[3] Additional tranches of 10% will follow on a staggered schedule, and the total unlock across all tranches eventually covers over 1.37 billion shares.^[3]

This matters for two reasons. First, the sheer scale: $116 billion of newly liquid stock is larger than the entire IPO proceeds raised in most full calendar years. Second, the timing: SpaceX has already broken below its $135 offer price, hitting roughly $131 — an all-time low for its brief public life — before recovering to around $136.^[4][5] The stock’s return from IPO is essentially flat at +0.2%, despite a +19.2% first-day pop.^[5]

The historical base rate on lockup expirations is mixed — some deals absorb the supply without incident, others see material selling pressure. But the scale here is unprecedented. No prior IPO has created this much potential sell-side supply at a single unlock event.

A reasonable forecast: if SPCX trades above $135 into the unlock, selling pressure from early investors and employees is likely to be material. If it trades below, the question becomes whether enough buyers see the dip as an entry point. I would put the probability of a meaningful drawdown (defined as a decline of 5% or more within two weeks of August 6) at roughly 60%, with the 40% case being that institutional demand absorbs the supply the way it did after the first-day pop. The key variable is whether the August 4 earnings report delivers enough incremental information to reset the narrative.

AI Infrastructure IPOs Hit Turbulance

Two IPOs tested the AI infrastructure trade in the week ending July 19. Both stumbled.^[4]

Data center operator Csquare (CSQR) priced below its $23–$27 range at a steep discount to publicly traded peers and fell 2% on debut.^[4] The deal, which raised approximately $1 billion, drew scrutiny for its high leverage and ongoing losses — and its closest comps offered a dividend, which Csquare does not.^[4]

Standard Nuclear (STDN), an early-stage nuclear fuel company, slashed its offering size by more than half before pricing, then plunged 18% on its first day.^[4] The deal ran into both a broader selloff in AI infrastructure stocks and cooling interest in speculative growth plays, compounded by poor trading from recent IPO X-Energy.^[4]

The broader Renaissance IPO Index fell 8.3% that week, underperforming the S&P 500 by nearly seven percentage points.^[4] The damage was concentrated in AI names:

The rotation was visible on the upside too — SailPoint gained 14.4%, Figma added 13.5%, and Venture Global rose 12.7% — suggesting capital is moving from AI infrastructure into software and energy, not simply exiting the IPO market.^[4] Despite the selloff, the Renaissance IPO Index remains up approximately 15% year-to-date.^[4]

Consumer Issuers Step Into the Pipeline

While AI infrastructure IPOs are finding the going tougher, consumer-facing companies are testing whether appetite extends beyond the technology trade.

Blackstone-backed Jersey Mike’s Subs filed for an IPO on July 2 and launched its roadshow on July 20, offering 43.5 million Class A shares at a price range expected to price in the coming week.^[6] The chain grew revenue to $724 million in 2025, up roughly 11% from $653 million, with same-store sales growth of 3% and nearly 3,300 locations — making it the second-largest sandwich chain in the US behind Subway.^[6]

Cumberland Farms, the gas-station and convenience-store operator, filed its F-1 the same day, adding to what Bloomberg described as a “swelling IPO pipeline” broadening beyond AI.^[6]

These are different animals than the AI infrastructure deals. Jersey Mike’s is profitable, growing at a moderate single-digit same-store rate, and backed by a major private equity sponsor with a clear exit timeline. The question is whether investors, having been burned on speculative growth offerings, will pay up for a steady consumer franchise — or whether the broader selloff in consumer discretionary names this year (the sector was roughly flat in the IPO Index that week, versus Technology at −4.4% and Utilities at −9.1%)^[4] has dampened appetite across the board.

The $2.1 Trillion Pipeline: Measuring Potential, Not Promises

As of July 22, Forge’s technology IPO pipeline carries a reported $2.1 trillion in cumulative valuation across companies at various stages — from news-mention candidates to formal S-1 filers to confidential submissions.^[7] Enterprise software accounts for 51.2% of that total, followed by fintech at 17.0%, industrials at 9.6%, and technology hardware at 7.8%.^[7]

That number is best read as a map of potential supply, not a forecast of realized market capitalization.^[7] A company in the confidential-filing stage has indicated regulatory preparation, but has not established a final valuation, price range, exchange, or launch date. The practical takeaway: the pipeline tells us issuance activity is likely to continue, but the composition and timing will be highly selective.

S&P Global counted 192 US IPOs (including SPACs) in the first half of 2026, up from 168 in H1 2025.^[7] But 118 of those were SPACs, and the 74 traditional IPOs actually represented a lower count than the prior year — even as proceeds increased substantially.^[7] The average non-SPAC IPO size reached $598.7 million, compared with $162.1 million a year earlier.^[7] The market is active, but it is active because large issuers can raise exceptional amounts, not because every venture-backed company has an equally open path.

Market Structure: Thinner Than It Looks

Beneath the surface of record IPO activity, the plumbing of the equity market has been changing in ways that could amplify the impact of large supply events.

Market liquidity depth contracted 23% in the first half of 2026, with average bid-ask spreads widening across major equity exchanges.^[8] Traditional lit exchanges — NYSE and Nasdaq — now represent only 42% of equity volume, down from 51% in 2025, with the remainder absorbed by dark pools, alternative trading systems, and off-exchange block trades.^[8]

JPMorgan research indicates that executions requiring 15-minute windows now move prices 31% more than equivalent trades in 2024.^[8] A $1 billion institutional position that assumed 15-minute liquidity in baseline scenarios now faces 35-minute exit windows under identical conditions — effectively multiplying tail risk by 2.3x for non-correlated positions.^[8]

For the IPO market specifically, this matters because newly public stocks often have thin floats and concentrated institutional ownership. If a lockup expiration releases a large slug of shares into a market where depth at every price level is already compressed, the price impact of any given order will be larger than historical models suggest. The 44.5% average first-day gain for technology IPOs in H1 2026^[7] may reflect strong demand — but it also reflects limited float, and what works on the way up can work in reverse when supply expands.

Buybacks Continue, But Won’t Offset the Supply Wave

On the other side of the ledger, corporate buyback activity remains robust. Equinor (EQNR) will start its third 2026 buyback tranche on July 23, covering up to $1.125 billion.^[9] Ericsson, STMicroelectronics, Eni, Ryanair, and Prosus all reported ongoing repurchase programs during the July 13–20 window.^[9]

These buybacks provide a steady demand counterweight, but they are distributed across individual names and timeframes — not concentrated where the supply is. The $116 billion of SpaceX stock unlocking on August 6 dwarfs any single buyback program. The buyback thesis is real but insufficient as a structural offset to the wave of new and newly liquid supply.

What to Watch Next

The base case is that the IPO market remains open through the second half of 2026 — the Nasdaq IPO Pulse, a cyclical indicator of issuance activity, remains near its April high and in an upturn.^[2] But the composition is shifting. The easy money was in AI infrastructure mega-deals; the next phase requires investors to price consumer franchises, unprofitable growth stories, and the supply overhang from the deals already done. The August 6 unlock is the first real stress test.
