Five percent of US market capitalization is about to enter public markets through three IPOs.
Paul Tudor Jones laid out the structural read on Invest Like the Best. The contemplated IPOs over the next year represent 5-6% of US market cap. Normal IPO issuance runs 0.5 to 1% in active years. The 2026 pipeline runs ten times that ratio.
The mechanism is direct. Buyback capacity has supported equity prices for a decade. The mega-IPO pipeline reverses it. The funding for SpaceX, OpenAI, and Anthropic is already being pulled out of existing technology stocks. Magnificent Seven weakness year to date is the rotation, not a coincidence of earnings cycles.
Standard 180-day lockups place the insider supply wave in Q1 through Q3 of 2027. The 2000 parallel is exact. Supply hit demand at the same moment fundamental concerns began to bite.
For physician allocators, healthcare sits structurally outside this pipeline. That creates the asymmetry worth positioning for.
