Cardano at 8th place with a 3.6 billion market cap whereas Chainlink is at 12th place with 2.7 billion markets. So in the race between the two, which altcoin is going to hit $10 Billion Market Cap First? Read to know
https://coinpedia.org/news/cardano-vs-chainlink/these projects are completely different, while Chainlink is a protocol token on top of ETH platform, that is providing oracles for smart contracts, Cardano wants to be a competitor for the complete Ethereum scope of services, as smart contract platform
from my point of view, Cardano should be first to hit $10B, if any of these coins/tokens ever reach $10B valuation
