Coinbase shares closed at USD 194.00 on September 18, 2026, after jumping 11.7% during the NASDAQ session. The rally followed renewed strength in Bitcoin, which reclaimed USD 80,000 and briefly moved above USD 81,000.
Yahoo Finance placed Coinbase among the S&P 500’s strongest percentage gainers that day, while TradingKey recorded an 11.66% advance. The move made COIN one of the strongest crypto-linked stocks in the completed session and set up fresh attention for September 21 trading.
Coinbase Global Inc., identified by ISIN US19260Q1076, finished well ahead of the broader market. TradingKey said the NASDAQ Composite gained about 0.40% on September 18. Crypto-related stocks, by contrast, formed one of the session’s strongest groups and posted several double-digit gains.
The performance came as investors returned to digital-asset exposure. Bitcoin’s rebound above USD 80,000 supported interest in companies tied closely to crypto trading, market activity, and digital-asset demand. Coinbase became one of the clearest beneficiaries during the session as the crypto-linked group outpaced gains across technology and semiconductor shares.
The available data did not provide detailed intraday price levels for COIN. Still, the closing price and documented percentage increase showed a large gap between Coinbase and the wider technology market. This spread kept attention on whether crypto momentum could extend after Bitcoin briefly traded above USD 81,000.
Coinbase CEO Brian Armstrong also renewed a long-term Bitcoin projection. In a podcast shared on September 21, he said Bitcoin could reach USD 400,000 by 2030. The forecast differs from the version of his outlook that he gave in January, while his broader bullish stance remained unchanged.
Armstrong linked the projection to several factors. He cited expanding institutional adoption, clearer regulation, Bitcoin’s halving cycle, scarcity, and macroeconomic debasement. He said those forces could attract more capital over the next four years and increase Bitcoin’s value and standing in global markets.
He also pointed to institutional demand as a major driver. According to Armstrong, spot Bitcoin ETFs are purchasing Bitcoin at a rate 20 times higher than daily mining output. He tied that demand to growing confidence among companies and institutions entering the crypto market under a more supportive regulatory backdrop.
Armstrong also framed Bitcoin as more than a short-term market trade. He described the asset as part of a longer-term shift in how the global economy functions. This view supports his expectation that adoption, scarcity, regulation, and institutional buying could work together through 2030.

Armstrong said regulatory progress could continue even if the CLARITY Act fails to secure approval. He said the Commodity Futures Trading Commission and Securities and Exchange Commission could continue shaping crypto rules. He expects a more defined US framework to develop through legislation or agency action.
Coinbase also added a product-development angle before the new week. TradingView commentary said Coinbase Derivatives submitted a rulebook update with the SEC on September 18 regarding proposed single-stock perpetual contracts. Traders may watch that filing alongside crypto prices as the September 21 session develops.
The filing adds another issue for markets to track after Coinbase’s sharp rebound. It follows a session in which digital-asset strength had a much larger effect on COIN than the broader NASDAQ advance. The company therefore enters the new week with both market and regulatory developments in focus.
Market attention on September 21 centers on whether Bitcoin can hold above the USD 80,000 area after its latest recovery. COIN’s recent jump, Armstrong’s USD 400,000 Bitcoin target, and the derivatives filing now shape the immediate news flow around the company.
