Why is Hedera (HBAR) up 23.12% Today, September 29, 2026? IBM Cloud Listing and AI Identity Demand Lift HBAR

HBAR outperformed a weak broader tape, rising 23.12% on heavy participation (about $1.51B volume, ~0.29x market cap), suggesting catalyst-driven demand rather than a sector beta move. The main drivers were an IBM Cloud Catalog listing for a Hedera-based enterprise identity product and attention to HCS-27's AI-agent trust/auditability standard. Elevated turnover and rising derivatives activity also increase near-term reversal risk if momentum fades.
