Jito's MEV-optimized staking mode works as follows: Users stake SOL to receive JitoSOL, a liquid staking token. The pool delegates stake to validators running the Jito-Solana client, which captures MEV via bundle auctions—searchers bid tips for profitable transaction ordering. These tips, plus standard staking rewards, boost JitoSOL yields (typically higher than native staking).
Solana selling pressure factors from the 2023 JTO airdrop (100M tokens, ~$165M value): Many recipients sold claimed JTO for profits, increasing short-term SOL demand (to claim/pay fees) but potential indirect pressure if proceeds swapped to SOL. However, no major sustained SOL dump occurred; wealth effect fueled ecosystem activity instead.
