Riot Platforms Jumps 18.58%, MARA 11.26% as US Indexes Close Mixed

The scale of the miners' moves dwarfs the broader crypto-equity complex, with Riot and MARA posting double-digit gains while exchange and infrastructure names like Coinbase and Circle logged far more modest advances. That gap suggests the buying was concentrated in bitcoin-proxy equities rather than a uniform risk-on rotation across crypto-linked stocks, especially with the major indexes mixed. The open question is whether this miner-specific bid persists or proves to be a single-session spike disconnected from the wider market.
