Best Solana Altcoins to Buy as $SOL ETF Approval Odds Surge to 90%

According to Bloomberg Intelligence, the odds of a $SOL ETF getting approved in the U.S. have risen to 90%, up from 70% in February.

That’s huge. Why?

• A spot ETF approval often triggers massive inflows, just like we saw with Bitcoin and Ethereum.
• It gives institutional investors legal pathways to gain $SOL exposure.
• It positions Solana as a top-tier, investable asset alongside BTC and ETH.

The surge in demand is already visible:

• $SOL futures open interest is near its all-time high, currently at $5.75 billion.
• Total Value Locked (TVL) across Solana’s DeFi protocols is up to $9.5 billion.
• $SOL is holding above key support at $140, aiming for $200+ before ETF approval (expected Oct. 10).
