SpaceX is reportedly lining up four major Wall Street banks for a potential 2026 IPO — a move that could signal the long-awaited reopening of the public markets after a years-long IPO drought.
In the meantime, late-stage private companies like SpaceX are finding other ways to create liquidity for employees and early shareholders, largely through a fast-growing secondary market.
To unpack what SpaceX’s IPO chatter means, how private liquidity works before a debut, and what investors are looking for in today’s pre-IPO giants, we spoke with Greg Martin, managing director at Rainmaker Securities, a broker-dealer specializing in secondary share transactions for late-stage private companies.

Greg, welcome to the show. Before we dive in, can you share a bit about your background?
I’m founder and managing director of Rainmaker Securities, which specializes in helping large late-stage, pre-IPO companies transact shares in the secondary market. I am also the founder of a secondary firm that buys private company shares called Archer Capital Group, and co-founder of Liquid Stock, a business that helps employees and executives exercise their options using their shares as collateral.
I’m sure the secondaries business has been booming with this IPO drought from the past couple years.
No doubt. Private companies are staying private much longer now. Many of these businesses — including SpaceX and other companies that would be top 30 in the S&P 500 — would historically have gone public years ago.
