Coinbase Stock (COIN) Is in a Giant Broadening Wedge

Coinbase stock (COIN) has bounced roughly 30% from its February 12 low of $139. That low came on the same day the company reported $7.2 billion in 2025 revenue and doubled its crypto trading market share. The fundamentals looked strong – but the stock sold off anyway. So what does the chart say now?

A giant broadening wedge is building on the weekly chart

A broadening wedge is a pattern where the price swings between two trendlines that move apart over time. The highs get higher and the lows get lower, like a megaphone. It tells you that buyers and sellers are getting more aggressive – and volatility is expanding, not compressing.

On COIN’s weekly chart, you can draw an upward-sloping trendline connecting the peaks in March 2024, December 2024, and July 2025. And a (slightly) downward-sloping trendline connecting the lows in September 2024, April 2025, and February 2026. That gives you the broadening wedge.

The key point: COIN just tagged the lower trendline support and bounced hard. Each time the price has touched that lower line, buyers have stepped in. Three successful tests in a row is a decent sign that the support is holding.

What to watch next

The February 12 low of $139 is the level to watch. That’s the most recent touch of lower trendline support. As long as COIN stays above it, the pattern stays intact and the bounce could have more room to run.

If the stock breaks below $139 on a weekly close, the broadening wedge breaks down and the setup is invalidated. That would suggest sellers have finally overwhelmed the buyers at support.

And if the price ever gets back to the top of the wedge – maybe consider it as resistance.
