IO token surged over 50% in the moments following its spot market debut on Upbit, South Korea's leading cryptocurrency exchange, which listed the asset on its KRW trading pair at 09:00 UTC.
The sharp rally reflects typical listing momentum on major regional exchanges, particularly in South Korea where retail participation often drives initial price discovery. Upbit's listing represents a significant expansion of IO's accessibility to Korean traders, who represent a substantial portion of global crypto trading volume.
The token's performance underscores continued demand for newly accessible assets among Asian retail investors, though the sustainability of such listing-driven gains typically depends on sustained trading interest and broader market conditions.
