A "Steam account" option has quietly appeared on the Polymarket login page, listed alongside entry points such as Google, MetaMask, Phantom, Rabby, Coinbase Wallet, and WalletConnect. This marks the first time a prediction market has integrated a gaming platform account as an identity credential, directly tapping into the traffic of Steam's approximately 147 million monthly active users. (Previous coverage: Polymarket and Kalshi race to launch crypto perpetual contracts, prediction markets storm Coinbase's $2.9 billion moat) (Background: Polymarket's latest valuation hits $15 billion, raising funds twice in one month; yet still trails Kalshi's $22 billion valuation) The login portal for prediction market leader Polymarket has been quietly updated. Official login displays show that in the "Welcome to Polymarket" pop-up, the first position in the wallet grid now features a Steam account login option. This is the first time a gaming platform account has been included as an identity credential entry point for a crypto-native application. Steam appears on the login page According to screenshots, the top of the Polymarket login pop-up still prominently features "Continue with Google" and email verification buttons, with the wallet and identity options grid below. The first row, from left to right, includes Steam, MetaMask, Phantom, and Rabby; the second row includes Coinbase Wallet, Rainbow, etc.; and the final row features WalletConnect. Steam is not a crypto wallet, which implies that Polymarket is utilizing the Steam OpenID OAuth authentication process. Once a user completes the login process with their Steam account, Polymarket automatically generates a custodial embedded wallet for them, consistent with the existing Google login mechanism. This allows Steam users to enter the prediction market without needing to download MetaMask or manage seed phrases. Valve banned crypto in 2021 The irony of this change lies in the historically firm stance against crypto held by Steam's parent company, Valve. In October 2021, Valve officially updated its Steam developer policy to prohibit any games "built on blockchain technology that issue or allow the exchange of cryptocurrencies or NFTs," leading to the removal of various blockchain games and NFT projects at the time. Valve co-founder Gabe Newell stated that "virtual items on the Steam platform should not have real-world value," noting that crypto payments had previously caused user dissatisfaction and that many crypto-related transactions were prone to fraud. This stance has remained unchanged as of 2026, and the Steam store still does not allow games with crypto-related content. However, Steam has never restricted third-party applications from using Steam's OpenID for identity authentication. This is a long-standing open interface used by hundreds of third-party services, including Twitch and Discord. Polymarket's move effectively bypasses Valve's store policy; rather than pushing crypto products into the Steam store, it is instead funneling Steam gamers into a crypto-native application.
