Ondo Finance has launched Ondo Global Markets, offering 100+ tokenized U.S. stocks and ETFs on the Ethereum blockchain, with hundreds more planned. This initiative aims to merge traditional finance liquidity with on-chain assets. While Ethereum is the underlying asset, the ticker for the tokenized stocks is $SBET, though some users are debating the correct ticker and expressing concerns about potential market cap discrepancies and promised buybacks for other related tokens like $BMNR.
