PitchBook: the number of “inside rounds”, where only previous investors participate, rose to over 1,000 in 2020 with $30B invested, up 15% from 2019
Venture capitalists may be getting too comfortable with marking up their own portfolios. — The number of inside rounds …
Context & Ripple Effects
PitchBook's count of over 1,000 inside rounds in 2020 — $30B invested, up 15% from 2019 — landed at the front edge of the funding surge that followed: US startups went on to raise a record $329.8B in 2021, more than half of it in $100M+ rounds. When the only bidders are a company's existing investors, the marks they set become the baseline for everything priced after.
The same dataset now reads as an early-warning indicator: when outside price discovery returned, PitchBook counted down rounds at a 10-year-high 15.9% of deals in 2025, and the buyer base itself had contracted, with active US VCs falling to 6,175 firms. Insider-priced capital was the bridge between those two states.
First-order effects
- Founders who took inside money in 2020 skipped a fresh outside valuation check, letting existing investors extend or raise marks unopposed across $30B of financings.
- Limited partners in funds leading these rounds hold $30B of positions whose only pricing evidence comes from the managers marking them, not from any arm's-length transaction.
Second-order effects
- Insider-set marks became the reference prices underwriting the 2021 mega-round wave, where $190.8B of the record total came in $100M+ rounds priced off prior valuations.
- When new outside capital eventually repriced those positions, the accumulated gap surfaced mechanically as down rounds — concentrated heavily in AI and ML portfolios by 2025.
Third-order effects
- With the VC population down to 6,175 firms and nine firms capturing over half of 2024 fundraising, insider-dependent pricing concentrates further into fewer hands, widening the private valuation–liquidity gap between paper marks and exit-ready prices.
- If the pattern holds, inside rounds function as a cycle amplifier: insiders prop up marks in downturns and bid up prices in booms, deferring rather than preventing the eventual repricing.
The trend: Venture pricing is shifting from arm's-length auctions toward insider-led marks, with the deferred outside repricing showing up later as down rounds.
