Ethereum Price Prediction: BlackRock Reportedly Buys $1.5B in ETH as Rally Extends

Ethereum price prediction for September 22 stays bullish above $2,447, the 0.5 Fibonacci level ETH cleared this week as it pushes toward the 0.618 Fib at $2,672 for the first time since January.

ETH trades near $2,664, up 0.76% today, pushing into $2,672, a level that’s marked its ceiling since before this year’s crash. Clear it, and ETH is trading somewhere it hasn’t been since January.

The chart backs the move. Every major EMA sits below price and rising, the 20-day near $2,502, the 50-day near $2,335, both the 100-day and 200-day close together around $2,200 to $2,226. That’s a clean, fully bullish stack. RSI at 67 still has room before hitting overbought territory, so this doesn’t look like a move running out of gas.

The one thing worth watching: a long-term trendline from last year’s high runs almost exactly through this same $2,672 zone. So this isn’t just a round number, it’s the point where two separate signals, the Fib level and the trendline, agree. A clean daily close above it would matter more than most breakouts this year.

Bitcoin and Ethereum are both on pace for standout third-quarter performances, according to trader Kashif Raza. Bitcoin trades near $81,500 and is up 38% in Q3, which would rank as its third-highest Q3 return on record, notable because September has historically been Bitcoin’s weakest month. 

Raza noted BTC is currently up roughly 3% for the month, and a green September close would give Bitcoin its first-ever four-year streak of positive Septembers.

Ethereum’s quarter has been stronger still. ETH trades above $2,600, its highest level in 233 days, up roughly 70% in Q3, which Raza said would mark Ethereum’s best third quarter ever if it holds through the close.

That’s the claim, according to a video from Altcoin Daily. A few things worth separating out here, since they carry different weight:

• The argument: Investor Thomas Lee said AI and robotics are going to generate huge volumes of machine-to-machine micropayments, traffic banks aren’t equipped to handle securely, and that Ethereum ends up as the default rail for it. His case goes further, enterprises could eventually hold ETH the way a company holds real estate, as a balance sheet asset tied to something they actually use
• The claim getting the most attention: The video says BlackRock’s public wallet addresses show a $1.5 billion Ethereum purchase, with BTC and ETH making up its two largest crypto holdings. That’s Altcoin Daily’s own read of on-chain data, not something independently traced here, so treat it as reported rather than confirmed
• The supporting voices: On-chain analyst Willie Woo was cited saying ETH buying has built steadily since February and that sellers are largely spent, with the market having absorbed the selling that followed the CLARITY Act’s failure. Trader Kevin Olirri said he’s changed his mind entirely, he used to think Bitcoin and Ethereum alone would dominate crypto’s value, but now expects different sectors to standardize on different chains, and he’s actively evaluating Solana, Avalanche, Hyperliquid, and Zcash

US spot ETH ETFs added $143.80 million on September 18, a fourth straight inflow day after three rough outflow sessions earlier in the week totaling more than $400 million according to SoSoValue. Even with Thursday’s bounce, the week is still tracking a net $140 million outflow, a reversal from three straight positive weeks that added over $1.7 billion between mid-August and early September. 

BlackRock’s ETHA led the inflow at $114.32 million, and remains the largest fund by net assets at $9.35 billion. Grayscale’s legacy ETHE, which has bled $5.43 billion since converting from a trust, holds $1.91 billion.

ETH clears $2,672 and confirms a break of the descending trendline from the 2025 high. Continued institutional buying and ETH’s strongest Q3 on record could support a push toward the psychological $3,000 level, with the 0.786 Fib at $2,990 the next test along the way.

ETH fails to clear $2,672 and slips back below the 0.5 Fib at $2,448. A reversal in ETF flows or fading momentum after this month’s sharp run-up would fit that scenario, exposing the 50-day EMA at $2,335 and the 100-day at $2,198 as the next supports.
