Cardano Leios testnet launch spurs whale buying and price support

Input Output Global confirmed that the Cardano Leios testnet will go live in June 2026, targeting a 10‑ to 65‑fold increase in throughput and aiming for over 1,000 transactions per second by the end of the year, with a mainnet rollout planned for late 2026. The upgrade is seen as a key step toward addressing Cardano’s scalability criticisms.

On‑chain data shows whales accumulated more than 240 million ADA over five days, coinciding with a roughly 22 % rebound in the ADA price. Analysts note that the cryptocurrency is holding a long‑term support zone that has historically acted as a turning point in previous market cycles, suggesting a potential structural reversal.

The combination of the upcoming testnet and renewed buying activity has placed Cardano back on traders’ watchlists, with the market watching whether the testnet results will validate the network’s capacity to sustain high transaction volumes and drive further price gains.
