Bitcoin Surpasses $80K as Altcoins Rally and AI Trading Enters Crypto Market

Crypto markets are shifting in September 2026, with Bitcoin holding above $80,000 and altcoins gaining strong capital flows.

Ethereum has surged over 20% across the latest weekly move, reaching $2,500. The ETH/BTC ratio also moved toward 0.030 after a May low near 0.024 to 0.027, suggesting stronger Ethereum demand against Bitcoin and potentially supporting a wider altcoin rally.

Solana has a strong market setup, with SOL gaining about 28% across one week tied to the latest crypto rally. Solana ETFs have crossed $1.1 billion in cumulative inflows, while spot Solana ETFs added $33.49 million in one session, marking the largest daily inflow since mid-December 2025.

XRP has shown even stronger price momentum, with recent market data placing its seven-day gain near 40% to 50%. Seven regulated spot XRP ETFs have also drawn about $1.4 billion in cumulative flows, supporting further gains but also creating the risk of sharp reversals when buyers lose control.
