The crypto market is stepping into the second half of 2025 with strong momentum, thanks to political calm and rising institutional investments.
Well-known crypto analyst Ali Martinez ran an interesting experiment, he asked Super Grok, an advanced AI, to think like Polymarket and spot which altcoins could see the biggest gains this year.
Here’s what that bold test revealed.
Here’s the list of top altcoin with biggest gain in 2025.
Solana (SOL) takes the top spot with a 14% probability of being 2025’s best-performing altcoin. Solana has made a name for itself as the “speed king” of crypto, thanks to upgrades like Alpenglow driving swift transactions.
Its lively “meme coin” scene and exciting tech have turned heads with year-to-date gains of +11%.
Coming in second is Pudgy Penguin isn’t just a memecoin; it’s breaking into the real world. Thanks to viral videos (over 180 billion views!), toy deals, and even a tie-up with NASCAR, PENGU now trades at $0.043 with 24% YTD gain.
With an ETF application filed and strong brand buzz, “Super Grok” gives it a promising 12% chance of top returns.
AI is transforming crypto, and Bittensor is at the forefront. There’s strong developer activity, low supply, and a focus on Web3 artificial intelligence. TAO is up 37% YTD, now at $437.7.
However, Grok’s model gives it a 10% shot of leading the pack, assuming the AI narrative keeps surging.
Similarly, Ondo (ONDO), leading the Real-World Asset (RWA) tokenization trend, is gaining favor with institutions. Currently, ONDO is priced trading at $1.02, reflecting a 14% YTD it offers unique upside if institutions favor it in the next bull run, with an 8% chance of top performance.
Hyperliquid flies under the radar but boasts fast trading and no new coins unlocking until the year’s end. Its current price is $43.7, seeing a rise of 1259% YTD, with a 7% probability it’s the year’s dark horse.
Sui, with its focus on privacy and user experience, lingers below past highs, priced at $3.84 (+359% YTD). If the underlying tech catches on, SUI could “10x” and deliver outsized returns of 6% probability.
Ali Martinez and Grok’s playful “prediction market” exercise says Solana and Pudgy Penguin have the best shot at leading 2025 gains, but in crypto, staying curious and early matters just as much as picking the right token.
Solana (SOL) tops the list with a 14% chance of being 2025’s best-performing altcoin, driven by speed, upgrades, and meme coin buzz.
PENGU is rising due to viral content, real-world deals, and ETF buzz, with a 12% chance of top altcoin gains in 2025.
Ondo leads RWA tokenization, appealing to institutions with 14% YTD gains and 8% potential for top performance in 2025.
Altcoins often follow BTC momentum; a strong Bitcoin rally boosts risk-on sentiment and drives capital into altcoins.
