Access to on-chain stock tokens varies significantly for U.S. investors, with different platforms adopting divergent regulatory strategies. Securitize's broker-dealer platform serves eligible U.S. investors, while Robinhood advertises 24/7 on-chain stock token trading but explicitly excludes the United States and U.S. persons from its offering. The split highlights ongoing compliance challenges in the tokenized equities space, where U.S. securities regulations restrict direct access to certain on-chain products for domestic investors despite growing global adoption of blockchain-based stock trading.
