Polymarket named Travis VanderZanden chief growth officer on August 11, tasking the veteran operator with scaling the prediction market platform as it prepares for a surge in U.S. political betting ahead of fall events.
VanderZanden founded Lyft and Bird, the scooter-sharing startup that went public in 2019 before filing for Chapter 11 bankruptcy in 2024. He held roles at Uber before launching his own ventures. His hire comes as Polymarket, which operates a decentralized prediction market with roughly 600,000 users, is expanding its U.S. team and overhauling its marketing approach, according to a company statement.
Polymarket operates a peer-to-peer platform where users trade contracts tied to real-world events: election outcomes, economic data releases, sports results. The platform does not take a position on trades; it collects fees on each transaction. Users deposit dollars or stablecoins and receive trading capital. The platform reported $3 billion in volume across its lifetime as of mid-2025 and has processed roughly $30 billion in notional value since its 2020 launch, according to public disclosures.
VanderZanden's appointment comes as Polymarket builds growth mechanisms that depend on executive talent with track records scaling two-sided marketplaces. Lyft scaled from launch in 2012 to a $24 billion valuation at its 2019 IPO. Bird, launched in 2017, reached a $2.3 billion valuation in 2018 before capital discipline tightened. Both ventures required sustained user acquisition and retention engines, the mechanism VanderZanden is expected to apply to prediction markets.
Polymarket operates in a regulatory gray zone. The Commodity Futures Trading Commission has asserted jurisdiction over prediction markets as derivatives exchanges; Polymarket maintains that its use of Ethereum and decentralized settlement exempts it from CFTC oversight. No enforcement action against Polymarket has been announced. The platform has restricted access to U.S. users from non-New York addresses through geo-blocking, citing CFTC concerns.
The hire occurs as prediction markets have drawn capital and media attention ahead of the November 2024 U.S. presidential election and beyond. Kalshi, a CFTC-licensed prediction exchange, opened election contract trading following a court ruling in July 2024 that limited CFTC authority over certain event derivatives. Polymarket's volume on U.S. election contracts has grown steadily since the CFTC's failed enforcement effort against the platform in 2021.
VanderZanden joins Polymarket as the platform competes for users against newer entrants and licensed operators. Growth in prediction market volume and user bases tends to concentrate around discrete events, elections, sporting finals, economic data milestones, rather than sustain at baseline. A growth officer's mandate typically includes retention mechanics beyond event-driven spikes and geographic expansion into markets where regulatory clarity exists.
