Cardano (ADA) pumped roughly 20% last week (from ~$0.1646 on July 27 to ~$0.19–0.20 by early August 2026), making it the best-performing top-100 coin. No single factor explains it — several catalysts worked together: **1. Whale accumulation (the biggest driver)** Large whales (wallets holding 100M–1B ADA) bought more than 240 million ADA (~$44 million) in under a week, per Santiment data. This group now holds over 14.3 billion ADA (~39% of circulating supply). The buying pressure absorbed supply near the lows. - [Finbold](https://finbold.com/heres-why-cardano-emerged-as-the-best-performing-top-100-coin-last-week/) - [CryptoPotato](https://cryptopotato.com/cardano-ada-grabs-traders-attention-after-a-20-weekly-increase-further-pump-incoming/) **2. The "van Rossem" hard fork (July 18)** Cardano's first fully on-chain-governed hard fork, which reduced smart-contract execution costs, added new Plutus functions, and marked a key step in the Voltaire governance era. This boosted bullish sentiment. - [Finbold](https://finbold.com/heres-why-cardano-emerged-as-the-best-performing-top-100-coin-last-week/) **3. IBC interoperability progress** Cardano's first IBC connection to Injective launched on testnet (announced Aug 3), enabling cross-chain asset transfers. CoinGecko noted ADA saw a ~5% pump following the successful testnet integration. - [Bitcoin Foundation](https://bitcoinfoundation.org/news/analysis/cardano-jumps-20-in-a-week-why-ada-is-back-on-investors-radar/) **4. Rising trading volume / open interest** Futures volume surged ~380% (from ~$150M to ~$650M in a week), signaling sharply increased market participation and momentum. - [CryptoPotato](https://cryptopotato.com/cardano-ada-grabs-traders-attention-after-a-20-weekly-increase-further-pump-incoming/) **5. Broader market recovery + technicals** A stronger Bitcoin and more bullish altcoin environment helped ADA hold gains. Analysts also noted ADA was heavily oversold and approaching its 20-week moving average — a setup that historically preceded "big pumps." Some set targets like $0.2305 (end of downtrend) or even $2.90. **Notable caveat:** Santiment flagged that the rally came while the number of non-empty Cardano wallets was actually *declining* — meaning retail hasn't fully re-entered yet, and stronger buyers (whales) are absorbing supply. - [CryptoPotato](https://cryptopotato.com/cardano-ada-grabs-traders-attention-after-a-20-weekly-increase-further-pump-incoming/) - [Bitcoin Foundation](https://bitcoinfoundation.org/news/analysis/cardano-jumps-20-in-a-week-why-ada-is-back-on-investors-radar/)
