Ripple’s XRP, Stellar (XLM), and Cardano (ADA) have become the best performers in Grayscale Investments latest weekly ranking of leading cryptocurrencies, posting the strongest percentage gains among the top 10 crypto assets by market cap. As of August 7, 2025, the snapshot indicates increasing investor demand in certain altcoins as the market looks forward to possible regulatory approval of spot exchange-traded funds (ETFs).
XRP, Stellar, Cardano Seize The Spotlight Amid ETF Hopes
On the front of the pack was XRP, which surged more than 9.7% in the previous week taking its year-to-date increase to a resounding 59.4%. At the time of Grayscale’s snapshot, its market capitalization stood at $196.4 billion, which speaks to its status as the largest players in the field.
Behind XRP, Stellar boasted 9.1% gains last week to give it an annual return of 31.8% and a valuation of $14.3 billion. Meanwhile, Cardano came next with gains of 6.3% over the week, trimming its year-to-date losses to 6.8% and commanded a market capitalization of $28.7 billion.
Next in line was Dogecoin (DOGE) with a 6.1% surge while Ethereum, the King of altcoins, saw a 5.8% gain. Tron (TRON) and Solana (SOL) trailed behind with a profit of 4.2% and 1.9%, respectively.
Amid the positive sentiment, XRP ETF 2025 approval odds have surged to 81% as Ripple and the U.S. Securities and Exchange Commission (SEC) resolved their five-year-long legal dispute. Whilst, Solana ETF boasts a higher chance of approval with the market pricing in 99% odds of launch, according to Polymarket.
Futures ETFs Gain Traction
The latest surge in performance comes as futures-based ETFs tied to these altcoins are trading at a record volume. According to market trackers, XRP and Solana-linked futures ETFs have posted a near $3 billion in volume during recent weeks jointly. Although the price behavior of Solana remained more low-profile, the fact that XRP can be classified into this category seems to boost the intention to invest.
The attention of major investors, in its turn, is going to Cardano. According to blockchain statistics, in 48 hours, 200 million ADA worth $157 million went into whale wallets, as reported by CNF. Analysts view this move as a positive indication of confidence before probable approval of Cardano ETFs and the market odds have now reached 75%. This could serve as a catalyst that might push ADA price above the $1 mark in the coming times, per expert predictions.
For context, futures-based ETFs contrast to spot products since they monitor contracts, instead of the underlying token. Still, the blistering development of such funds is commonly regarded as preconditioning the question of spot ETF attention. Regulators like the SEC typically look for signs of liquidity, price discovery, and robust risk management before granting approval.
