Before You Cheer The IPO Window, Watch Where The Money Goes

Overview

The reopening of the IPO market in 2026 is a concentration event, not a broad recovery, argues Marc Schroder of venture firm MGV. A small set of giant listings led by SpaceX, OpenAI and Anthropic dominates the window. The larger effect for most startups is stronger acquisition activity, because newly public AI giants would become some of the best-capitalized buyers on the planet, and M&A, not IPOs, is the exit path for most founders and investors.

Key Takeaways

A handful of mega-listings, not a wide range of companies, is driving the 2026 IPO window, so the reopening reads as concentration rather than a return of broad demand.
The bigger consequence for the average startup is a deeper pool of well-funded acquirers, since SpaceX, OpenAI and Anthropic would hold enormous cash once public.
Acquisitions have long been the dominant exit for venture-backed companies, making the financial health of buyers more important to most founders than IPO access.
Schroder advises founders to build assets buyers want: ownership of real workflows, proprietary data that compounds, evaluation and testing infrastructure, and a wedge into AI platforms.
Capital has rotated heavily into AI, stalling other pipelines such as crypto listings, which sharpens the concentration story.
The real test of a durable IPO market comes later in 2026, when follow-on listings show whether demand extends beyond the few largest names.

Why The 2026 IPO Window Is Concentration, Not A Broad Recovery

Schroder's central point is that a reopened market and a healthy market are not the same thing.

The wave of high-profile filings looks like a recovery after a long stretch of thin venture liquidity. Schroder argues the reality is narrower. A short list of giant companies accounts for most of the activity, which means demand is concentrated in a few names rather than spread across many.

Because of that concentration, he warns founders against reading the headlines as a green light for their own IPO plans. The window is open for the largest, most visible companies. For the typical startup, the path to a payout still runs through being acquired, not through ringing the opening bell.

SpaceX, OpenAI And Anthropic Anchor The Listings

Three names dominate the story and set the scale of the moment.

›SpaceX priced near a $1.77 trillion valuation and raised about $75 billion at $135 per share on the Nasdaq, the largest IPO on record.
›OpenAI submitted a confidential filing in early June, pointing toward a listing later in 2026.
›Anthropic filed confidentially on June 1 at a $965 billion valuation, following a funding round at that level.
›Together these three carry combined valuations in the trillions, far above the rest of the pipeline.

How A Single Raise Dwarfs The Whole Prior-Year Market

The size gap between these deals and the broader market is the clearest evidence for the concentration argument.

SpaceX alone aimed to raise about $75 billion. That figure is larger than the roughly $47.4 billion raised across the entire 2025 U.S. IPO market. One company, in one offering, outweighs a full year of listings from everyone else combined.

When a few deals soak up that much capital and attention, there is less oxygen for smaller companies hoping to follow. Schroder notes that capital rotating into AI has stalled other pipelines, including crypto listings, which reinforces how lopsided the window has become.

Why Acquisitions Matter More Than IPOs For Most Founders

The strongest practical takeaway is about who buys companies, not who lists them.

Schroder's view is that the vast majority of venture exits have always been acquisitions, not public offerings. So the most useful effect of these mega-listings is not a longer IPO queue. It is a larger, richer set of potential acquirers.

Once SpaceX, OpenAI and Anthropic are public and sitting on large cash balances, they become some of the best-funded buyers anywhere. For founders and investors whose portfolios exit through M&A, the financial strength of those buyers matters more than whether the IPO window stays open.

What Founders Should Build To Attract AI Buyers

If acquisition is the realistic exit, Schroder points to the assets that make a startup worth buying.

›Ownership of a real workflow that customers depend on day to day.
›Proprietary data that compounds in value over time and is hard to replicate.
›Testing and evaluation infrastructure that large AI platforms need.
›A market wedge that gives an acquirer faster entry into a segment.

The common thread is that these are things a large AI platform would rather buy than rebuild. Building toward them reframes success around being a strong acquisition target instead of chasing a public listing that few companies will reach.

Rising Deal Activity And The Real Test Ahead

Early signals support the M&A thesis, but the durability of the window is still unproven.

AI dealmaking rose roughly 90% year over year in the first quarter, and active buyers have been closing acquisitions at a faster pace, which fits Schroder's argument that the acquirer pool is expanding. More well-capitalized buyers tends to mean more deals and better terms for sellers.

The open question is whether the IPO market broadens. Schroder frames the real test as the follow-on listings later in 2026. If demand stays trapped in a few giant names, the window will have been a concentration event rather than the start of a wide recovery.

Frequently Asked Questions

Does a reopened IPO market mean it is a good time for most startups to go public?

Not according to Schroder. He argues the window is concentrated in a few giant companies, so most startups should still plan around being acquired rather than listing publicly.

Why would a public SpaceX, OpenAI or Anthropic matter to small startups?

Once public, these companies would hold large cash balances and rank among the best-funded acquirers in the world. That deepens the pool of potential buyers for startups that exit through M&A.

How large is the SpaceX IPO compared with the rest of the market?

SpaceX aimed to raise about $75 billion at a valuation near $1.77 trillion. That single raise is larger than the roughly $47.4 billion raised across the entire 2025 U.S. IPO market.

What should founders build if acquisition is the likely exit?

Schroder points to assets buyers want: ownership of a real workflow, proprietary data that compounds, testing and evaluation infrastructure, and a wedge into AI platforms.

What is the real test of whether the IPO market has truly recovered?

The follow-on listings later in 2026. If demand extends beyond the few largest names, the recovery is real; if not, the window was a concentration event.

The 2026 IPO surge is led by a few giant names, so the practical message for most founders is to prepare for acquisition rather than a public listing. Watching where the new capital flows, and which buyers grow stronger, tells more about startup outcomes than the IPO headlines alone.
