5WPR Stablecoin Trust Index Shows AI Engines Rate USDC Highest, USDT Tenth

5WPR announced in a press release the release of the Stablecoin Trust Index 2026, which measures how major AI engines describe 25 leading stablecoins following the implementation of the U.S. GENIUS Act. The study found that AI systems such as ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews now categorize stablecoins as compliant, hedged, or warned when users ask about their safety or regulation.

USDC ranked first in the index with a trust score of 95, described by AI engines as the default safe stablecoin due to its reserve attestations and alignment with the GENIUS Act. Other compliant tokens include PYUSD, USDP, RLUSD, USA₵, and JPMorgan's Kinexys. USDT, the largest stablecoin by market capitalization at about 189 billion dollars, placed tenth with a score of 52. AI engines acknowledge its scale but qualify it for its offshore structure and contested audit history.

The report also notes that crypto-collateralized and synthetic stablecoins such as DAI, USDe, FRAX, and crvUSD are categorized as hedged, while collapsed tokens like TerraUSD and BUSD remain cited as cautionary examples. The full study, covering methodology and findings, is available on 5WPR's website without access restrictions.
