#Solana# Investor sentiment regarding the potential approval of a spot Solana ETF has strengthened in recent weeks, with new data indicating growing confidence that 2025 may be the year when the green light is finally given.

According to the decentralized prediction market Polymarket, the chances of the Solana ETF being approved by the U.S. Securities and Exchange Commission (SEC) have risen to 83% as of June 1. This marks a sharp recovery from the low levels in April, when optimism briefly dipped below 70%, before gaining momentum in May and stabilizing at higher levels.
The jump in confidence coincides with the increasing activity around ETF proposals related to Solana. One of the key events is the ongoing review by the SEC of a rule change proposed by NYSE Arca, aimed at registering the Bitwise 10 Crypto Index Fund. This fund includes Solana along with major assets like Bitcoin and Ethereum, offering a potential opportunity for institutional exposure to SOL.
Although the Commission recently postponed its decision on the proposal by moving the deadline from June 1 to July 31, the market remains optimistic. The delay, instead of signaling rejection, seems to reflect the complexity of the proposal and broader regulatory caution.
Meanwhile, REX Shares and Osprey Funds are following a separate path, having filed an application for a "staking ETF" that will allocate capital to Solana and Ethereum and generate returns on at least half of the fund's assets. However, this proposal has drawn the attention of regulators. The SEC raised questions about whether the fund's structure meets the criteria set forth in the Investment Company Act, which could lead to additional legal hurdles. Despite the regulatory uncertainty, the overall tone has shifted towards optimism. While the SEC continues to evaluate its options, many market participants are wagering that 2025 could be the breakthrough year for Solana ETF.
