Kalshi has officially launched fully regulated Dogecoin (DOGE) perpetual contract trading in the United States, offering retail investors a legal avenue to trade perpetual contracts on the meme token within the CFTC regulatory framework. These contracts are subject to strict leverage limits, with a maximum of 3.8x for long positions and 2.8x for short positions, and benefit from tax advantages under Section 1256 of the U.S. Internal Revenue Code, where 60% of gains are taxed at the lower long-term capital gains rate and 40% at the short-term rate. Kalshi, previously known for its prediction markets, sees this expansion as a continuation of its business model's shift towards the crypto space.
