Corporate AI spending is expected to rise from an already meaningful $140 billion base to $1.3 trillion by 2032, indicating a large addressable market. The forecast suggests room for private AI infrastructure and application vendors to capture expanding budgets over the next decade.
Scale AI’s valuation reached $29 billion in 2025 after Meta invested about $14.3 billion for a 49% stake, making it one of the largest private AI infrastructure transactions. The company has also raised over $1.6 billion from investors including Meta, Amazon, and Accel.
Hamilton Lane says the odds favor that AI is not in a valuation bubble, but the firm frames the issue as a valuation question rather than a technology question. That still leaves private AI companies exposed to multiple compression if growth expectations slow.

Pre-IPO investments carry significant risks. Portal AI shares are illiquid, meaning there is no public market to sell them quickly. There is no guaranteed exit timeline or return. The investment is speculative in nature, and investors should be prepared for the possibility of total loss. Valuations of private companies can fluctuate substantially between funding rounds. Investors should consult their financial advisor and review all offering documents before investing.
In a pre-IPO transaction, accredited investors purchase shares from existing shareholders (such as employees, early investors, or other holders) through secondary market platforms. The company itself does not issue new shares in these transactions. UpMarket facilitates these trades as a FINRA-registered broker-dealer, handling compliance, documentation, and settlement on behalf of both parties.
There are two primary exit paths for pre-IPO holdings: selling your shares on the secondary market to another buyer, or holding until the company completes an IPO or is acquired. Both paths are subject to transfer restrictions, company approval (right of first refusal), and market conditions. The timing of any exit is unpredictable, and investors should plan for a multi-year holding period.
The minimum investment for most pre-IPO offerings on UpMarket is $50,000. This amount may vary depending on the specific offering and share availability. There are no fees to create an UpMarket account or browse available investments. Investors only pay transaction-related fees when they complete an investment.
UpMarket's valuation estimate of is derived from a proprietary model that incorporates multiple data sources: funding round data (Caplight), revenue estimates (Sacra), secondary market pricing, and public company comparables. The model applies a private company discount to the public comp multiple to account for illiquidity and information asymmetry. This estimate is not investment advice and may differ substantially from the price at which shares actually trade.
