Charles Hoskinson reacts to ADA’s latest rally with “#LeiosIsComing” as Cardano’s Linear Leios upgrade advances toward a planned late-2026 rollout.
Cardano founder Charles Hoskinson has tied ADA’s latest rally to renewed attention around Ouroboros Leios, quote-posting a price chart with a simple message: “#LeiosIsComing.”
The post came as ADA pushed toward $0.27, but the bigger story is that Leios itself is still moving through testing rather than launching on mainnet today.

Hoskinson reacted to a post calling ADA a “sleeping giant waking up.” The quoted 15-minute ADA/USDT chart showed price jumping from roughly $0.244 toward $0.264 before his response.
ADA went on to close around $0.2704 on Oct. 5, after trading near $0.244 two days earlier. That works out to roughly an 11% move across the period. Price has since cooled, with ADA trading near $0.253 on Oct. 7.
Leios Is Still a Forward-Looking Catalyst
Hoskinson’s hashtag should not be read as confirmation that Leios has already gone live.
Cardano’s official documentation says Linear Leios is the version planned for mainnet as part of the first phase of the Dijkstra hard fork, currently targeted for late 2026.
The upgrade is designed to raise throughput by allowing producers to create larger “endorser blocks” alongside normal Praos blocks.
The public Leios testnet, Musashi Dojo, has been running since June 23. Cardano says the rollout remains subject to governance and will also depend on enough stake pools registering the BLS keys needed for the voting process.
Earlier development plans estimated Leios could expand Cardano’s throughput capacity by roughly 10x to 65x through a phased rollout. Those figures describe the intended scaling improvement, not current mainnet performance.
ADA Rally Already Had More Than One Driver
The timing also matters.
Hoskinson’s post followed the rally rather than clearly preceding it, so the move cannot be attributed to Leios alone. Cardano had already seen fresh attention after RealFi launched on mainnet on Oct. 1, while derivatives activity also expanded sharply.
The Crypto Basic reported this week that ADA open interest climbed to $304 million, its highest daily close since at least early April, while whale transactions above $100,000 jumped to 413 on Oct. 5.
That makes the current setup broader than one social-media reaction. ADA rallied as fresh leverage entered the market, RealFi moved onto mainnet, and Hoskinson brought Leios back into focus.
The next development to watch is not another hashtag, but whether the Dijkstra process advances toward an approved mainnet rollout and whether the network activity following recent launches begins to match the technical expectations surrounding Leios.
