现在 Polymarket 推出自己的稳定币，USDC 会发生什么？

Polymarket’s plan to roll out its own collateral token sounds, at first glance, like the kind of move that should eat into Circle's USDC . A platform swaps out USDC.e, introduces Polymarket USD, and the obvious retail question follows almost immediately: Does that mean less demand for USDC? The short answer is no. Polymarket USD is being introduced as a token backed 1:1 by native USDC, while the platform is phasing out USDC.e, the bridged version of USDC it previously used on Polygon. The wrapper is changing, and the user experience is changing, but the underlying reserve asset still points back to Circle’s own stablecoin. That means the move, by itself, doesn't pull dollars out of USDC circulation or mechanically shrink USDC’s market cap. Why this matters What changed is not the reserve asset but the interface users interact with. If more platforms issue their own dollar tokens backed by USDC, demand for USDC may still grow, but it becomes less visible at the surface level and more dependent on platform design and control. It's important to make that distinction because USDC is now so large that any kind of imprecise language can obscure more than it explains. CryptoSlate data currently places its market capitalization at roughly $77.9 billion , making it the second-largest stablecoin after Tether's USDT and the sixth-largest cryptocurrency. Circle says USDC is fully backed by highly liquid cash and cash-equivalent assets and redeemable 1:1 for dollars, with reserve holdings disclosed weekly and tested through monthly third-party assurance reports. To understand Polymarket's move, you need to separate three things that often get blurred together: native issuance, bridged representation, and platform-specific collateral. Native USDC is the token that Circle issues and redeems. Bridged USDC, in this case USDC.e, is a version that represents USDC locked elsewhere. Circle’s own description of bridged USDC says it's backed by USDC on another blockchain locked in a smart
