Upbit's trading volume jumps 273% as Korea returns to crypto

Trading volume on Upbit, South Korea's largest and dominant crypto exchange, jumped 273% as domestic investors moved back into digital assets, The Block reported. One analyst cited in the report described South Korean capital as moving back to crypto gradually, characterizing local investors as "return-chasing" rather than loyal to any single asset class, meaning they follow whichever market offers the better short-term payoff rather than sticking with crypto or stocks out of habit.

That description fits the first half of 2026 closely. Dunamu, Upbit's parent company, saw consolidated operating revenue fall 49.1% year over year to 408.1 billion won, about $289 million, while Bithumb's operating revenue dropped 48.7% to 168.8 billion won and the exchange swung to a net loss of roughly $77 million. The reason wasn't a lack of Korean risk appetite. It was where that appetite went: the KOSPI more than doubled in the first half of the year, driven by a surge in semiconductor stocks, and pulled capital straight out of the country's crypto exchanges.

• Upbit trading volume increase: 273%
• Dunamu (Upbit parent) H1 2026 revenue: down 49.1% to $289 million
• Bithumb H1 2026 revenue: down 48.7% to about $120 million
• Bithumb H1 2026 result: swung to a roughly $77 million net loss
• KOSPI performance in H1 2026: more than doubled

A single day of higher volume doesn't undo two quarters of capital flight on its own, but the timing lines up with a broader shift. South Korean retail traders have a well-documented habit of moving fast between domestic equities and crypto depending on which one is producing better returns at the moment, and Bitcoin's run to above $75,000 this week gives that comparison a fresh answer. Whether the spike marks the start of a sustained rotation back into Korean crypto trading, or a short burst that fades once the global rally cools, will show up in whether Upbit's volume holds over the coming weeks rather than in any single day's number.

The stakes for Upbit and Bithumb go beyond one good trading day, and beyond South Korea's borders too. Exchange revenue in South Korea runs almost entirely on trading fees, so a swing from record-low volume back toward the exchange's more typical range translates directly into revenue recovery, the kind Dunamu and Bithumb both need after a first half that cut their operating results roughly in half. A sustained rotation back into crypto would also matter beyond the exchanges themselves: South Korean retail flows have a long track record of adding real depth to altcoin and large-cap trading alike, and a market that spent the first half of the year watching capital chase semiconductor stocks instead would notice the difference if that flow keeps building rather than fading after one strong session. Upbit alone handles the large majority of won-denominated crypto trading in the country, which means its volume trend is close to the best single gauge available for how South Korean retail sentiment toward crypto is shifting from one week to the next.
