The probability of a spot Cardano ( ADA ) exchange-traded fund ( ETF ) being approved has surged as investors await a decision from the Securities and Exchange Commission (SEC). Specifically, market-implied odds for a 2025 approval have risen to 64%, representing a 54% increase in bullish sentiment compared to earlier this year, according to insights from the betting platform Polymarket.

Notably, ADA ETF approval odds fluctuated throughout Q1 and early Q2. However, recent regulatory developments, such as appointing crypto-friendly Paul Atkins as the SEC chair, have strengthened investor confidence. SEC’s extended ETF decision On February 24, the SEC acknowledged NYSE Arca’s proposal to list and trade the Grayscale Cardano Trust shares, formally starting the regulatory review process. That triggered a standard 45-day extension, pushing the decision deadline to May 29. While such extensions are routine, the market appears increasingly hopeful for approval. Currently, 72 crypto-related ETF applications are pending with the SEC. Only two are Cardano-specific: the Grayscale Cardano Trust and the Tuttle Capital 2X Cardano ETF, a leveraged product. If approved, these ETFs would mark a significant milestone for ADA, potentially boosting institutional adoption and lending greater legitimacy to the asset. Meanwhile, momentum surrounding the ADA ETF continues to build, despite controversy involving founder Charles Hoskinson. On May 7, NFT artist Masato Alexander accused Hoskinson of misusing access during the 2021 Allegra hard fork to transfer 318 million ADA from unclaimed 2017 ICO tokens, with only $7 million allegedly reaching the governance group Intersect. In 2021, Charles Hoskinson unilaterally used his genesis keys to REWRITE the Cardano ledger and take control of ₳318m ($619m) By comparison, when the DAO hack happened in 2016, the Ethereum community forked over $60m. One of the largest ledger reorgs in blockchain history: 🧵 — masato_alexander (@masatoalexander) May 7, 2025 Hoskinson has denied the allegations, calling them false and affirming that over 99.8% of ICO tokens were redeemed correctly.
