ARK Invest CEO Cathie Wood said the firm’s research views stablecoins as monetary networks that become stronger as adoption grows, driven by trust, collateral use and integration across financial platforms.

Wood said those network effects have helped Tether’s USDT and Circle’s USDC establish dominant positions in the stablecoin market.

Referring to research by Director of Digital Assets at Arc Invest, Lorenzo Valente, she said newer entrants such as Open USD (OUSD) are unlikely to overtake market leaders.

In @ARKInvest’s view, stablecoins are monetary networks with effects that compound over time, thanks to trust, collateral utility, and integrations. The network effects of USDT and USDC have been powerful. @LorenzoARK explains convincingly why OUSD is unlikely to displace them. https://t.co/qEUimwpsiK
