Monthly IPO Roundup: April 2026 — March's Biggest Listings

March was the slowest month of Q1 2026 for US IPOs. Eight traditional deals priced, compared to 16 in February and around 6 in January. Volatility returned. A tech sell-off in late February, tariff headlines, and Middle East conflict uncertainty all gave institutional IPO investors reasons to wait. Per PwC's Q1 2026 US Capital Markets Watch, the quarter still closed as the strongest since 2021 by total proceeds, but March did the least of the lifting.

Two deals defined the month. PayPay, SoftBank's Japanese digital payments app, raised $879.8 million on March 12 and rose 14% on its first day. This was the largest-ever US listing by a Japanese company, and the first real proof that international fintech could capture US institutional appetite in 2026. A construction equipment rental platform, which PwC's report describes rising 32% on its first day, demonstrated that asset-backed, non-AI businesses could still command strong retail and institutional demand.

This is our April 2026 IPO roundup, covering March listings. For February's deals — Forgent Power's $1.5 billion industrial IPO and the biotech wave — see Monthly IPO Roundup: March 2026.

The Headline Deal: PayPay Raises $879.8 Million on Nasdaq

SoftBank Group-backed PayPay Corporation (NASDAQ: PPAY) priced on March 12, 2026, selling 55 million American Depositary Receipts at $16.00 each, with SoftBank Vision Fund II selling an additional 23.9 million ADRs — total proceeds of $879.8 million. The stock opened at $17.00 and closed at $18.16, a 14% gain from the offer price. Bloomberg reported on March 13 that PayPay's CEO confirmed the company was keeping a dual listing on the Tokyo Stock Exchange "on the table" following the successful US debut.

PayPay operates Japan's dominant QR-code payment application. As of its S-1 filing, the platform had approximately 67 million registered users, over half the adult population of Japan. Transaction volume runs in the trillions of yen annually. The company's revenue model mixes merchant fees, financial product distribution (insurance, consumer loans), and SoftBank ecosystem services.

Why the US listing? Japan's domestic equity markets, while large, trade at valuations that reward financial services companies less aggressively than US markets. SoftBank, which had been building toward a PayPay listing for years, chose Nasdaq specifically to access US fintech investor capital at higher comparable multiples. The Visa partnership announced alongside the IPO filing gave the deal an international expansion narrative. PayPay's QR code technology would integrate with Visa's network outside Japan.

What it means for brand ownership: PayPay going public on Nasdaq means US institutional investors now own a stake in Japan's most widely used payment brand. SoftBank Vision Fund II reduced its position through the offering. The IPO changes PayPay's accountability structure. Quarterly earnings, analyst coverage, and shareholder pressure on profitability all become factors that private ownership had insulated the company from.

The Construction Equipment Rental Platform

PwC's Q1 2026 report cited a construction equipment rental and tech-enabled fleet management company that rose 32% on its first day as one of the quarter's standout deals. This deal priced in late Q1 — consistent with March timing — and demonstrated that scaled, asset-backed operating models attracted strong institutional demand in 2026, not only software or AI names.

We track this deal because the ownership transition is consistent across asset categories. A PE-backed business goes public, early investors partially exit, and the company gains a public equity currency to use for further acquisitions. The 32% first-day gain reflected genuine demand from investors seeking infrastructure-adjacent companies with predictable cash flows.

Biotech Continues: Nscale and Clinical-Stage Names

The biotech IPO window that opened in January and accelerated in February carried into March with smaller but consistent deal flow. Nscale, an AI infrastructure company backed by Nvidia and headquartered in the UK, raised $2 billion at a $14.6 billion valuation in March 2026. This was not technically an IPO but a late-stage private round with Goldman Sachs and JPMorgan reportedly engaged as lead underwriters for a planned IPO later in 2026.

Healthcare remained the most active sector for public market issuance. The diabetes-device carve-out mentioned in PwC's Q1 summary, an established diabetes management device business spun out of a larger healthcare conglomerate, also priced in Q1, adding to the broad sector diversity of Q1 listings.

The Quieter Close: Why March Pulled Back

The factors that slowed March:

Tech sell-off spillover. Software and growth equities pulled back in late February and early March as investors repriced AI-infrastructure valuations and concern grew about rising oil prices and Middle East escalation. IPO books are built through a 2-week roadshow; any institutional pullback during that window can force deal delays or price cuts.

Tariff uncertainty. US trade policy uncertainty resurfaced in March with additional tariff proposals, creating caution among cross-border deal participants. PayPay, despite being a Japanese company, priced successfully because its US fintech investor narrative was well-developed.

The pipeline was building, not deploying. Several of the most-watched 2026 IPOs — Plaid, Discord, Cerebras — were still in S-1 preparation or awaiting better market windows. March's relative quiet was a pause in flow, not a signal of structural market closure.

Q1 2026 in Review

Q1 2026 closed as the strongest opening quarter since 2021. The full picture:

• 22 traditional IPOs priced in Q1, raising over $9.4 billion
• February led with 16 deals; March lagged with 8
• IPO aftermarket outperformed the S&P 500: 2026 IPOs traded down ~1% vs. the S&P's ~5% decline through March 31
• SPAC formation hit its highest level since 2021: 62 SPAC IPOs raising $11.8 billion
• Pharma and life sciences accounted for 7 of 22 traditional IPOs — 6 of them biotechs — a massive increase from the 7 total biotech IPOs in all of 2025

The quarter validated what dealmakers at January's ICR Conference had predicted: the IPO window would be open, consumer and healthcare companies would lead volume, and institutional demand would be selective but present for the right deals.

Deals That Didn't Price in March

Cerebras Systems. The AI chip maker had been targeting a 2025 IPO before regulatory delays. As of March 2026, Cerebras was finalising its amended S-1 filing. It refiled on May 4 targeting $115 to $125 per share. By May 14 the stock priced at $185, raising $5.55 billion. The deal that wasn't in Q1 became the headline deal of early Q2.

Visma. Norwegian enterprise software giant Visma, backed by Hg, postponed its planned €19 billion London IPO to late 2026 in late February, citing the global selloff in software stocks and fears that generative AI from Anthropic and others could disrupt its professional services business. This reflected a pattern across European software. AI disruption concerns were suppressing valuations more severely than in the US.

Invea Therapeutics and Edison Oncology. Both biotech companies withdrew their IPO filings in Q1 2026, contributing to the sense that the biotech window was open for strong stories like Aktis and Generate but not for undifferentiated or early-stage pipelines.

FAQ

What was the biggest IPO of March 2026?

PayPay Corporation raised $879.8 million in its March 12, 2026 Nasdaq listing — the largest-ever US IPO by a Japanese company. The ADRs rose 14% on the first day.

Is PayPay available in the United States?

PayPay operates primarily in Japan as a QR-code payments app. Its US Nasdaq listing makes the company's shares available to US investors, but the PayPay app itself is not a major US consumer product. Its Visa partnership announced alongside the IPO filing suggested possible future expansion.

Why was March 2026 quieter than February for IPOs?

Late February's tech sell-off, tariff headlines, and geopolitical uncertainty combined to reduce institutional risk appetite during the critical 2-week IPO roadshow window. Deals that were not strong enough to price in those conditions delayed into April and later. The largest 2026 watch-list names — SpaceX, OpenAI, Discord — remained on track for Q3 and Q4 per their stated timelines.
