Solana and XRP climb as crypto market cap passes $4 trillion, driven by fresh inflows and ETF optimism. Investors pushed Solana toward roughly $219 and XRP briefly above $3 in early September 2025. The rise happened across global markets, with strong interest from European investors and large non-U.S. XRP ETF flows. Market participants cited expectations for U.S. ETF approvals plus Solana network upgrades and growing DeFi activity. Prediction markets like Myriad also priced bullish outcomes, amplifying momentum.
Momentum for Solana
Solana’s rally reflected both fundamentals and flows. European demand and dedicated Solana inflows into funds lifted bids across spot and derivatives venues. Developers continued to ship upgrades, improving block times and reducing congestion. Those network improvements support more DeFi and NFT activity, which in turn attracts capital. Traders noted that better throughput made Solana a more credible venue for high-volume apps.
XRP ETF flows rise
XRP’s short squeeze was partially fueled by concentrated ETF-style flows outside the U.S. Large allocations into XRP ETF products pushed liquidity toward higher prices. Non-U.S. venues saw heavy subscription and secondary-market activity. That increased secondary-market demand tightened order books, allowing XRP to cross the $3 level briefly. Analysts warned that such flows can reverse quickly if approvals stall or market sentiment shifts.
U.S. ETF approvals
Expectations for U.S. ETF approvals were a central driver across tokens. Market participants expect approvals to broaden access for institutional investors. If regulators clear spot or product-based ETFs, inflows into crypto markets could accelerate. Those approvals would likely change custody, compliance, and market structure. For now, approval timelines remain uncertain, so risk is still present.
Solana inflows surge
Dedicated Solana products and ETFs attracted fresh capital in Q3 2025. Fund managers reported steady subscription rates from retail and institutions alike. That Solana inflows pattern coincided with upgraded tooling for developers and validators. Together, inflows and technical progress created a feedback loop supporting higher on-chain activity and token demand. Still, concentration risk exists if a handful of funds dominate flows.
Prediction markets: Myriad
Prediction markets amplified bullish narratives as Myriad and similar platforms showed high probabilities for new highs. Traders used prediction contracts to hedge or leverage their views on ETF approvals and price targets. Those markets can move sentiment rapidly, nudging traders to reprice risk. While not a direct liquidity source, prediction markets served as a sentiment barometer during the rally.
DeFi, NFTs and payments
Real-world utility supported the moves beyond pure speculation. Solana’s low fees and speed helped DeFi TVL and NFT volume climb. XRP’s payments use case and partnerships continued to underpin demand narratives. Growth in DeFi lending, market-making, and NFT drops created on-chain demand for both tokens. That utility helped justify flows, even as short-term trading amplified volatility.
Q4 2025 outlook
Looking into Q4 2025, the market faces both tailwinds and risks. Tailwinds include potential U.S. ETF approvals and sustained institutional allocations. Risks include regulatory setbacks, macro volatility, or sudden outflows that could compress prices quickly. Traders should watch ETF application updates, fund inflows, and on-chain metrics for early signals. Diversified exposure and risk controls remain prudent.
How the move happened
The price action combined concentrated inflows, improved network fundamentals, and sentiment signaling from prediction markets. Specialized products funneled capital into Solana and XRP, tightening liquidity. Network upgrades and real-world use cases kept the narrative grounded. At the same time, macro and regulatory variables remained the main constraints on a durable leg higher.
Additional context and risks
While the headline—Solana and XRP climb as crypto market cap passes $4 trillion—captures the moment, market structure matters. Liquidity can be shallow at extremes, creating fast rallies and sharp pullbacks. Regulatory clarity on ETFs could either validate flows or trigger profit-taking. Investors should weigh on-chain adoption against concentration risks in fund ownership.
