Looking ahead to the end of 2026, here's what I'm watching: Solana's mainnet infrastructure could become competitive with—or even surpass—the major centralized exchanges when it comes to spot and derivatives trading volume. The network's speed and cost efficiency give it a structural advantage that might reshape how trading gets distributed across the ecosystem. Whether that actually materializes depends on adoption momentum and product-market fit over the next 18 months, but the pieces are aligning for a serious challenge to traditional CEX dominance.
