Steam is widely described as the dominant PC games storefront, with a library of over 100,000 games and a large installed user base that keeps expanding. Its scale gives the platform continued upside from game sales, in-game purchases, and publishing services.
Steam’s moat is reinforced by network effects: more players attract more developers, and more titles make the store more valuable for players. Morningstar notes network effects and switching costs are core sources of economic moats, both relevant to a platform like Steam.
A platform moat can erode if it fails to adapt to new developments, and Bullseye Research warns even wide-moat businesses face erosion risk when they become slow to change. For Steam, that means competition, regulatory pressure, or shifts away from PC gaming could weaken its dominance over time.

Pre-IPO investments carry significant risks. Steam 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.

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.
