The IPO Buzz: StubHub (STUB Proposed) & the September Gold Rush

StubHub Holdings (STUB Proposed) is the big name on the IPO marquee this week. The  online ticket reseller’s IPO – estimated to raise nearly $800 million – is the largest deal on this week’s IPO Calendar. Four companies – including StubHub – aim to raise a total of $2.36 billion by pricing their IPOs during the week of Sept. 15, 2025.

This sizable volume comes on the heels of last week’s big IPO run. Seven large IPOs raised about $4.39 billion combined during the week of Sept. 8, 2025. Three SPAC IPOs rang up a total of $665 million last week (the week of Sept. 8, 2025) – and two tiny IPOs raised about $11.6 million together. Altogether, these 12 deals raised combined proceeds of about $5.1 billion – ringing up the busiest IPO week since 2021.

  • Two IPOs – StubHub (STUB Proposed) and WaterBridge Infrastructure (WBI Proposed) – are set to price their deals tomorrow night – on Tuesday, Sept. 16, to trade Wednesday, Sept. 17 – both on the New York Stock Exchange.
