Goldman flags largest jump in net equity supply since 2000 — lockups and new issuance into 2027

2026-10-18 15:31 UTC

Markets are digesting a clear Equities, Liquidity catalyst titled "Goldman flags largest jump in net equity supply since 2000 — lockups and new issuance into 2027". The facts on the ground are that strategists are warning that tradable U.S. equity supply could jump sharply into 2027, with on the order of $1.7 trillion in lockup expirations plus roughly $600 billion of new issuance — the largest net supply increase since 2000.

Additional tradable shares absorb the same pool of buyer dollars, which means indexes need stronger earnings or buybacks to advance when net supply rises this quickly. Recent IPO holders, companies facing lockup expirations, and passive index investors usually feel additional supply before active stock pickers change their forecasts. Treat the supply wave as a drag on multiple expansion: winners can still outperform, but the index needs buybacks or inflows to overcome the new float. Buybacks and passive inflows absorb the new float without widening volatility. The risk case is that unlock waves coincide with higher rates, forcing marginal buyers to pick winners more narrowly. Follow-through in the named names versus the broad board.
