Analysis
I keep coming back to the same three names on every mega-IPO prospectus this quarter:
- Anthropic -- Goldman Sachs, Morgan Stanley and JPMorgan lead a listing targeting up to $2 trillion.
- Oura -- the same three banks, plus Allen & Company and Jefferies, lead a roughly $16 billion IPO.
- SB Energy -- targeting a $5 billion to $7 billion raise, drawing on the same limited pool of banks capable of running a deal this size.
- Nscale -- reportedly working toward a September listing on top of its own pre-IPO round.
That's four of 2026's largest technology and infrastructure listings, all competing for senior banker time at essentially the same three or four firms, in the same several-month window.
“- Anthropic -- Goldman Sachs, Morgan Stanley and JPMorgan lead a listing targeting up to $2 trillion.”
My read is that the actual constraint on how fast 2026's IPO pipeline can clear isn't investor capital -- there's clearly enough demand, given the valuations these companies are targeting -- it's the number of senior equity capital markets bankers who can run a listing of this complexity at any one bank. A trillion-dollar-plus IPO consumes an enormous amount of the same specialized team's time: roadshow scheduling, institutional investor meetings, pricing committee work, regulatory back-and-forth. Reuters reported that Anthropic's own IPO timeline has already slipped from late September toward mid-October, officially attributed to finalizing its credit facility -- but a compressed banker calendar, with the same senior teams simultaneously working Oura's and SB Energy's live deals, is a plausible contributing factor that wouldn't necessarily be disclosed publicly. Pulse covered that timeline shift in full when it was first reported.
This matters differently than a capital-availability problem would. If investor demand were the constraint, weak pricing or a withdrawn deal would be the visible symptom. If banker bandwidth is the actual constraint, the visible symptom is exactly what we're seeing instead: staggered timelines, sequential rather than simultaneous roadshows, and companies with genuinely enormous investor demand still waiting months longer than their own press releases originally suggested.
Room for disagreement: the more conventional explanation is simpler and probably carries more weight than my staffing theory -- these are extraordinarily complex financial structures (Anthropic's Long-Term Benefit Trust governance, SB Energy's related-party revenue concentration with OpenAI and Nvidia) that take genuine time to work through SEC comment cycles regardless of how many bankers are assigned to them. Regulatory review timelines, not banker calendars, may be the real gating factor, and attributing delays to staffing capacity risks understating how genuinely unusual some of these deals' disclosure requirements are.
What I'd watch either way: whether the banks staffing these deals start bringing in secondary underwriters -- banks like BofA Securities, Barclays or even newer entrants like Robinhood Securities, all of which appear further down Oura's underwriting list -- into lead roles on the next wave of mega-IPOs. That would be the clearest signal that capacity, not just complexity, was the binding issue all along.
