IPO Calendar: Upcoming US IPOs

A running list of upcoming and recently priced US IPOs, updated weekly. Dates, price ranges and deal sizes change frequently ahead of pricing — treat the table below as a snapshot as of August 26, 2026, and confirm details before making any decision.

Upcoming and Recent IPOs

What to Watch

• Lyntris broke issue on debut. The defense-tech connectivity roll-up priced its downsized IPO below range at $17.50 to raise $298 million at roughly a $2.0 billion valuation, then traded below its offer price and finished its first week down about 10% — a reminder that even backlog-rich defense names ($923 million in backlog as of June) aren't immune to weak aftermarket demand.
• Direct listings had a rough stretch. Ammunition maker First Breach (FBDT) completed a Nasdaq direct listing and lost roughly two-thirds of its value versus its $12 opening print within the week. Japanese earned-wage-access software firm Advasa Holdings (ADBT) completed its own Nasdaq direct listing on 8/25.
• SPACs keep the pipeline moving. JATT III Acquisition ($60 million, life sciences) and Southern Cross Acquisition II ($75 million) both priced blank-check IPOs on 8/26, continuing 2026's steady pace of SPAC issuance even as operating-company IPOs stayed quiet into the end of August.
• The bigger story is still off this calendar. Anthropic's IPO prospectus is expected to flag AI backlash and data-center opposition as a formal risk factor, and reporting says the company is arranging supervoting shares for its founders ahead of a listing some investors expect could value it near $2 trillion — potentially the largest IPO on record.

Fact vs. estimate: tickers, prices and deal sizes for already-priced deals reflect final terms as announced. Price ranges and deal sizes for deals not yet priced are estimates as filed/marketed and can change before pricing. Anthropic's valuation, supervoting structure and any listing timeline are unconfirmed estimates reported by multiple outlets, not a filed prospectus.

Why It Matters for Pre-IPO and Tokenized Equity Investors

This week's public debuts were small SPACs, a defense roll-up, and two direct listings that mostly traded down — not the kind of activity that moves markets. The name that would move markets, Anthropic, still isn't on this calendar, and reporting suggests its owners are moving to lock in founder control through supervoting shares before outside shareholders get a vote. That combination — a quiet public calendar and a mega-cap name still private — is exactly why pre-IPO and tokenized equity access exists as its own category: it lets investors get exposure to a company like Anthropic well before its eventual public price, or its backlash-related risk disclosures, become the only signal available.
