First-order effects

• Every future YC batch company now starts with roughly $100K of additional Stanford-and-Bloomberg money stacked on top of YC's own seed check, deepening the per-company capital pool at day one.
• Stanford and Bloomberg gain guaranteed early exposure to the entire YC pipeline — hundreds of companies per cohort cycle — without sourcing deals themselves.

Second-order effects

• Rival accelerators face pressure to attach their own marquee co-investors to standard terms, since YC's offer to founders is now visibly richer than its $12K Fellowship grants and prior deal structures alone.
• Later-stage investors, including YC's own Continuity Fund, see better-capitalized seeds arriving — the extra $100K shifts how much runway a demo-day graduate has before raising a priced round.

Third-order effects

• If the model holds, the accelerator stops being just a filter-plus-check and becomes a standardized capital-aggregation platform where universities and high-profile individuals buy portfolio-wide exposure through YC's deal terms — a structure that foreshadows YC's later move to raise multi-billion-dollar funds covering entire batches.
• Standardizing third-party money into the default seed terms blurs the line between accelerator, angel syndicate, and fund, concentrating deal access inside one program rather than spreading it across the venture market.
