Interesting, 21Shares launched an Anthropic Synthetic ETP in Europe today, first 100% exposure to a private co or cos. Ticker CLAU. To get the exposure they use total returns swaps on the Kaiko Anthropic USD Reference Rate which is derived from Binance's Anthropic perpetual futures. Prob no one in Europe will care but if they can figure out how to do this in the US (or some Asian countries) look out..
