As prediction markets are set to expand in 2026, three low-cap altcoins—UMA, Limitless, and Predict.fun—are positioned for potential growth. UMA, with a market cap of $63 million, plays a crucial role in supporting platforms like Polymarket and Story Protocol through dispute resolution. Limitless, valued at $21 million, reported a significant $760 million in notional volume in December 2025. Meanwhile, Predict.fun, operating on the BNB Chain, surpassed $100 million in volume and attracted 6,000 users. These altcoins are expected to benefit from the sector's anticipated expansion.
