🪂Excluding some non-airdrop supply, Hyperliquid gave away about 10B. 
For comparison (all in ATH):

Uniswap : 4.2B
Apecoin: 3.5B
DYDX: 2B
Arbitrum: 1.9B
Starknet: 1.9B
Zksync: 1.32B
Optimism: 1B (5 airdrops)
Celestia: 1B
EVMos: 800M 
Blur: 720M (3 airdrops)
LayerZero: 700M
1inch: 650M (2 airdrops)
Saga: 600M (9 airdrops)
Aptos: 430M
Paraswap: 400M
Forth: 380M
Jito: 350M

These are just estimates. It is difficult to quantify because some of these added more tokens (inflation), before reaching ATH (very difficult calculation for Optimism).
