The 2021 startup valuation bubble deflated but did not fully reset. Understanding why tells you something important about how private markets actually work.
Public market tech valuations corrected sharply in 2022 and have only partially recovered. Private market valuations lagged significantly. Many companies that raised at peak multiples in 2021 have not marked down those valuations in any formal sense — they simply have not raised new rounds, and without a new round, the old valuation persists on paper. This is not fraud. It is a feature of how private market accounting works. Marks are event-driven, not continuous.
The mechanism that typically forces reset — down rounds and distress fundraising — has been slower to arrive than many expected, for several reasons. Companies that raised large rounds in 2020 and 2021 built significant cash runways. Many extended those runways through cost cuts, layoffs, and revenue growth driven by AI tailwinds. The companies that needed to raise again quickly were forced to reset. Many others simply waited.
There is also AI. The generative AI boom created a new narrative that allowed some companies to reframe their valuations around AI potential rather than current fundamentals. This has kept some paper values elevated that would otherwise have corrected.
The remaining exposure is in the companies that are now approaching the end of their runway without having grown into their 2021 valuations. These companies will either raise at significant discounts, find buyers at distressed prices, or shut down. That process is happening but it is happening quietly, company by company, without the kind of visible market-wide correction that would register as a proper reset.
The bubble did not pop. It is slowly leaking.
