The IPO Market's Record First Half Sets Up a Liquidity Test for Late 2026

The first half of 2026 delivered the strongest US IPO market on record, and the second half will test whether that strength is structural or concentrated in two enormous deals. Sixty-nine IPOs raised approximately $132 billion in proceeds through June, including SpaceX’s historic $86 billion offering. Even excluding SpaceX, IPO proceeds totaled roughly $46 billion — nearly three times the level raised during the same period in 2025.{{cite:019a219ecfcd}} But SpaceX and SK Hynix together accounted for more than $100 billion of that total, a concentration that makes every clean reading of the market harder.{{cite:04a05c569aa5}}

Follow-on activity was equally robust, headlined by Alphabet’s record $44.75 billion offering, with $92 billion raised across 163 follow-ons versus $55 billion across 94 transactions in 2025. The convertible market is having another standout year as well, with $90 billion of issuance already surpassing the record pace set in the first half of 2025.{{cite:019a219ecfcd}}

The Mega-Deal Concentration Problem

SpaceX began trading on Nasdaq on June 12 under the ticker SPCX, debuting at $150 a share — $15 above its $135 IPO price.{{cite:ce45c3f7c85b}} The deal was structured with an unusually small public float of roughly 4.3%, meaning the vast majority of shares remain locked up with insiders, employees, and early backers.{{cite:dc0d09a89a72}}

What makes SpaceX’s structure distinctive is its phased lockup schedule. Rather than the standard 180-day blanket lockup, the company built in a series of release valves. After reporting earnings for the three months through June — its first results as a public company — insiders can sell up to 20% of their eligible locked-up shares, with an additional 10% available if the stock is trading at least 30% above the IPO price. A rolling schedule then unlocks another 7% at each of the 70, 90, 105, 120, and 135-day post-IPO marks. When SpaceX reports its second earnings report (for the quarter through September), an additional 28% becomes sellable. Whatever remains is fully released at the 180-day mark, which falls on December 8, 2026.{{cite:62b32dc5b54e}}

Founder Elon Musk’s approximately 6.4 billion shares remain locked until June 12, 2027, and he is excluded from all early-release provisions.{{cite:dc0d09a89a72}} The phased approach was designed in part to accelerate Nasdaq-100 inclusion: under rules effective May 1, companies with market caps above the 40 largest Nasdaq-100 members qualify for fast-track entry several weeks after their IPO, though they receive a lower weighting until free float expands.{{cite:62b32dc5b54e}}

The lockup calendar creates a staggered liquidity overhang. The first selling window opens after Q2 earnings, expected in late July or August. If insiders exercise even a fraction of their eligible shares at each checkpoint, the tradable float will expand materially before year-end — and with it, the supply the broader market must absorb.

SK Hynix: The Korea Discount Overcome

On July 10, South Korean memory-chip giant SK Hynix raised $26.5 billion in its US market debut, the largest-ever US IPO by a non-American company, topping Alibaba’s $25 billion offering in 2014. The company sold 177.9 million American depositary shares at $149 each, structuring the ADRs so US investors could buy in at roughly a tenth of what a full share costs in Seoul.{{cite:b1113b8e5a8f}}

Demand was more than seven times the available shares, and the stock opened at $170 — a 14% premium to the offer price.{{cite:b1113b8e5a8f}}{{cite:0ef68d1261e4}} That reception is notable because Korean companies have long traded at a discount to global peers — the so-called Korea Discount — attributed to complex corporate governance, low shareholder returns, and geopolitical risk. SK Hynix sidestepped that discount entirely because it makes high-bandwidth memory (HBM), a critical component of AI GPU processors, and counts Nvidia among its primary customers.{{cite:b1113b8e5a8f}}

The deal also carried a geopolitical dimension. US Commerce Secretary Howard Lutnick used a Micron event the same week to say he is already in talks with Samsung and SK Hynix about building factories in the United States. Micron separately announced plans to invest $250 billion in new US manufacturing.{{cite:b1113b8e5a8f}}

Goldman Sachs: Supply vs. Demand

The biggest concern investors raise about the IPO boom is whether new share supply will overwhelm the market. Goldman Sachs Research’s chief US equity strategist Ben Snider offered a framework for assessing that question in late June.{{cite:86c452450da0}}

Snider noted that roughly 50 US IPOs priced in the first half — about double the prior year and the largest number at that point in the calendar since 2021. In dollar terms, issuance was already tied with 2021’s record at roughly $120 billion. But the deal count itself is not exceptional: the 25-year average is about 100 IPOs per year, versus over 250 in 2021 and nearly 400 in 1999. In Snider’s view, the current pace is a far cry from euphoric sentiment in those prior episodes.{{cite:86c452450da0}}

Goldman Sachs’ IPO Barometer — combining interest rates, CEO confidence, and equity valuations — stands at 140, versus a long-term average of 100. That is not as high as 2021 but otherwise near the top of the range.{{cite:86c452450da0}}

On the supply-versus-demand question, Snider made three points. First, the number of deals is not exceptional even though dollar volume is. Second, markets grow over time: Goldman forecasts about $700 billion in total issuance (IPOs plus follow-ons) this year, which scales to roughly 1% of the equity market — actually lower than the long-term average and roughly in line with 2015–2019. Third, corporate buybacks are projected to exceed $1 trillion this year, meaning corporate demand for shares will outweigh corporate supply before even counting retail, hedge fund, or mutual fund demand.{{cite:86c452450da0}}

The math gets harder in 2027. Many of 2026’s IPOs came public with small floats, and as lockups expire, more shares will enter the market. That suggests a more challenging supply-demand balance next year.{{cite:86c452450da0}}

A Volatility Paradox

One of the more striking features of the current market is what Snider called a disconnect: index-level volatility has been low, with major indices near all-time highs, yet individual stock volatility has been extremely high. The explanation is very low correlations — stocks moving in different directions — which dampens index swings while amplifying single-name risk. Elevated investor leverage, including margin debt, hedge fund leverage, and the growth of leveraged ETFs, reinforces the expectation of continued volatility even if the bull trend persists.{{cite:86c452450da0}}

This matters for the IPO market specifically. Newly public companies with small floats are inherently more volatile — fewer shares mean each trade moves the price more. When lockup releases expand the float, that volatility can compress, but the transition period introduces its own price discovery turbulence.

The SEC’s Market Structure Overhaul

On June 11, 2026, the SEC proposed amendments to rescind two foundational provisions of Regulation NMS: Rule 611, the trade-through rule requiring brokers and exchanges to route orders to the venue displaying the best quoted price, and Rule 610(e), which prevents “locked” and “crossed” markets.{{cite:25c84d1ca7b5}}

Chair Paul Atkins framed the proposal as simplification: “After two decades of Rule 611, it is high time that the Commission review its unintended consequences that have hindered — rather than enhanced — the long-term growth of our markets.” The SEC noted that since the rules were adopted in 2005, the percentage of orders interacting with non-displayed liquidity has consistently increased, and US equity markets have become increasingly fragmented and complex.{{cite:25c84d1ca7b5}}

The practical impact is debated. Larry Tabb, head of market structure research at Bloomberg Intelligence, told The TRADE that brokers are unlikely to dramatically change routing strategies because they remain bound by best execution obligations. The bigger effect, in his view, falls on crypto and tokenized equity exchanges, which could now be folded into the SEC’s equity exchange framework. Without the trade-through rule, it becomes easier for a tokenized equity exchange to function with real-time settlement, since it would not need to route to other venues or pre-borrow securities for short sales.{{cite:25c84d1ca7b5}}

The SEC separately published its 2026 Regulatory Agenda on July 7, formally committing to propose rules enabling Bitcoin and other non-security digital assets to trade side-by-side with equities on SEC-regulated platforms under a single broker-dealer license.{{cite:b8dcd6388531}} A 60-day public comment period on the Reg NMS amendments is underway.{{cite:25c84d1ca7b5}}

The Private Secondary Market Keeps Growing

The private capital secondary market reached $220 billion in volume in 2025, another record year that exceeded expectations, with no signs of slowing in 2026, according to William Blair’s Private Capital Advisory team.{{cite:dc75a64565fb}} That growth matters for the IPO pipeline because it gives late-stage investors an alternative exit path. If secondary markets continue to deepen, some companies that might have rushed to go public in a weaker secondary environment can instead sell private shares — potentially filtering the IPO pipeline toward companies that genuinely need public capital for expansion, rather than those seeking liquidity at peak valuations.

What the Second-Half Pipeline Looks Like

EY’s Americas IPO leader Rachel Gerring has said that if filings convert into actual listings, the second half of 2026 could become one of the strongest IPO stretches since the 2021 boom.{{cite:04a05c569aa5}} An $80 billion-plus pipeline has been reported for the back half of the year.{{cite:b621523c9827}}

The candidates are different from the mega-deals that defined the first half. Kraken, Blockchain.com, ConsenSys, and Dataiku have all been reported as IPO candidates. Anthropic, last valued near $965 billion in private markets, is the wilder case — reports point more naturally toward 2027 than a rushed 2026 debut. Sierra Space has reportedly weighed a debut before year-end. Anduril Industries, the defense technology company founded by Palmer Luckey, was last valued near $14 billion and is being watched as a test of whether defense tech has its own public-market audience separate from the AI trade.{{cite:04a05c569aa5}}

General Atlantic’s global head of capital markets, Justin Kotzin, has argued that the next phase of the IPO comeback may be defined less by mega-deals themselves than by what follows: a broader opening incorporating mid-cap issuers, underrepresented sectors, and markets beyond this year’s busiest geographies.{{cite:b621523c9827}}

That is the test. A market that works only for SpaceX, SK Hynix, and perhaps Anthropic is open but narrow. The better signal will come from smaller listings — companies with $2 billion to $10 billion valuations in advanced manufacturing, defense, energy, and automation software. If investors buy those names, the market has genuinely broadened. If they only chase the same few mega-deals, 2026 will be remembered as a year when two gigantic offerings made the totals look healthier than the market underneath.{{cite:04a05c569aa5}}

Key Dates and Catalysts to Watch

What to Watch Next

The first real test arrives in late July or August when SpaceX reports its inaugural quarterly earnings. The lockup release that follows will be the first meaningful expansion of SPCX’s tradable float, and the market’s capacity to absorb insider selling without a sharp price decline will set the tone for how subsequent unlock dates are interpreted.

The second test is whether the second-half pipeline converts. Filings and banker chatter are not listings. The companies that actually price and trade in the coming months — particularly mid-cap names outside the AI-mega-deal complex — will reveal whether 2026’s record is a genuine reopening or a two-deal anomaly.

The third is regulatory. The SEC’s Reg NMS proposal and its broader crypto-equity trading agenda could reshape the plumbing of US markets in ways that matter more for execution quality and settlement than for IPO volume directly. But if tokenized equity exchanges gain a path to operate within the SEC framework, the definition of what constitutes a “public market” may widen in ways that affect how companies choose to list — and where.

The trajectory is clear: issuance is accelerating, supply is growing, and the market’s ability to absorb it has held so far. The 60/40 call is that it continues to hold through year-end, with buybacks and earnings growth providing the demand-side ballast. The 40 is the concentration risk — a market carried by two deals, facing a lockup calendar that front-loads supply into a window where sentiment could shift. If the first SpaceX lockup release produces a sharp drawdown, the psychological effect on the broader pipeline could be disproportionate to the actual share count involved.
