Business context and reporting period
Coincheck Group N.V. is the holding company for Coincheck, Inc., a Japan Financial Services Agency-regulated crypto asset marketplace and exchange. This Form 6-K, furnished in October 2026, reports preliminary operating metrics for October 2025 through September 2026, including figures as of September 30, 2026.
Key metrics
Trading volumes and customer assets are in millions of yen. The filing provides operating metrics, not revenue, profit, cash flow, margins, debt, or liquidity figures.
| Metric | Aug. 2026 | Sep. 2026 | Change |
|---|---|---|---|

Changes versus comparable periods
Compared with October 2025, September 2026 exchange trading volume was 52.8% lower, marketplace trading volume was 66.1% lower, and customer assets were 25.5% lower; verified accounts increased 17.4%. Exchange and marketplace volumes were lower in September than in October, while customer assets and verified accounts rose from August. These are monthly operating measures and do not establish changes in financial performance.
Outlook, risks, and unusual items
- The metrics are preliminary, unaudited, based on currently available information, and subject to updates. The company cautions that they should not be extrapolated to future periods.
- Beginning in June 2026, a substantial number of new verified accounts may come from crypto-as-a-service relationships. Third parties in these arrangements receive a significant portion of fee revenue generated by those accounts.
- Exchange trading volume includes transactions generally conducted without fees; Coincheck sometimes acts as a buyer on that platform to support marketplace activity. Marketplace transactions have historically been the primary source of total revenue.
- Customer assets include customer-held cryptocurrencies and deposited fiat currency, but exclude NFTs. The filing gives no earnings guidance or financial outlook.
Important facts for investors to verify
- Whether preliminary monthly metrics are revised in subsequent disclosures.
- The revenue and profitability contribution of marketplace activity versus exchange activity.
- The scale, economics, and revenue-sharing terms of crypto-as-a-service accounts.
- How customer asset levels and trading volumes compare with audited financial results and risk disclosures.
