Amazon’s AI Momentum Meets Options Resistance: Why the $280 Strike is Key Today

• AMZN is trading at $274.45, holding steady above key moving averages with a bullish MACD crossover.
• Heavy call open interest at $280 and $285 suggests this Friday’s options expiration will act as a magnet or a ceiling.
• Block traders are positioning for longer-term upside, buying deep-in-the-money calls expiring in Jan 2027 at $280 and $290 strikes.
• The Put/Call ratio of 0.66 indicates a clear bullish bias in sentiment, supported by record Q2 earnings and AWS growth.

Amazon isn't just moving; it's charging. After reporting record Q2 earnings driven by an insatiable hunger for AI infrastructure, the stock has climbed to $274.45 today. It’s a nice day for shareholders, but if you’re trading options, you need to look past the green candles. The market is caught between a rock of strong fundamentals and a hard place of options resistance. The real story here isn't just that Amazon is up—it's where the big money is hiding in the options chain.

The $280 Strike: A Wall of Calls

Look at the options flow for this Friday, August 7th. The open interest is heavily concentrated in call options, specifically at the $280 strike with 18,546 contracts. That’s not a coincidence. It’s a signal. When you see that much open interest at a specific strike just days before expiration, it usually means one of two things: either sellers are confident the price won’t break through, or buyers are betting on a sharp pop right up to that level.

The distribution tells a clear story. We have significant call OI at $280, $285, and $300. On the flip side, the put open interest is much thinner, clustered lower at $250 and $230. The total Put/Call ratio for open interest sits at 0.66. To put that in plain English, for every put contract, there are roughly 1.5 call contracts. That’s a bullish skew. It suggests traders are willing to pay a premium for upside exposure rather than hedging against a crash.

But here’s the catch. The stock opened at $272.89 and hit an intraday high of $278.31. It couldn’t quite close above $280. This makes the $280 strike critical. If the stock can’t hold above this level, those call buyers might get squeezed. However, the block trades tell a different, more optimistic tale. We saw large volumes of AMZN20270115C280 and AMZN20270115C290 being traded. These are long-dated calls. Smart money isn’t playing this week’s noise; they’re betting on Amazon’s AI run rate staying above $25 billion for the next six months. They’re buying the dip, not timing the hourly candle.

Earnings Fuel, But Valuation Looms

The news flow supports this bullish structure, but it’s not without nuance. Amazon reported Q2 revenue of $200.6 billion, beating estimates, and AWS revenue jumped 37%. CEO Andy Jassy’s comment that AI and Chips businesses are eclipsing $25 billion run rates is the kind of data that excites institutional investors. The market is re-rating Amazon from a retailer to an AI infrastructure giant.

However, we need to be honest about the risks. The stock is up 18% year-to-date. While the P/E ratio of 22.38 looks cheap compared to the broader market, the PEG ratio of 1.81 suggests the growth is already priced in. The recent 14% surge in July was impressive, but it left the stock overbought in the short term. The RSI is at 63, which is strong but not yet in the danger zone. Still, the gap between the current price and the 200-day moving average at $236 is wide. Mean reversion is a real risk if the broader market turns soft.

Where to Play It

So, how do you trade this? You don’t just buy the stock blindly. You use the options data to structure your risk.

For the stock, the technicals are supportive. The 30-day moving average is at $246.87, providing a solid floor. If you’re looking to enter a long position, I’d suggest waiting for a pullback to the $272–$274 range. Entering near the open today is risky given the intraday high of $278.31. A pullback to the open price level offers a better risk-to-reward ratio, with a stop loss just below the $270 support level.

For options traders, the setup is more interesting. The $280 calls expiring this Friday are the most liquid, but they are also the most volatile. If you believe the stock will break $280 by close, AMZN20260807C280 is the play. But be careful. If it stalls at $278, you’ll lose value to theta decay.

A smarter play might be next Friday’s expiration. Look at AMZN20260814C275. The open interest here is 12,912 contracts. This gives you an extra day for the thesis to play out. If Amazon continues its momentum from the Q2 earnings beat, this strike is closer to the money and offers better leverage than the $280 calls. Alternatively, if you want to play the long-term bullish block trades, consider the AMZN20270115C280. It’s more expensive, but it captures the AI narrative without the weekly theta bleed.

Bullish Trends Ahead, But Watch the Ceiling

The overall picture for Amazon is undeniably bullish. The combination of record earnings, AWS growth, and heavy institutional buying in long-dated calls suggests the path of least resistance is up. However, the $280 strike is a psychological and technical barrier. This week, expect volatility as traders square positions around that level.

If you’re trading, respect the resistance. Don’t chase the high. Wait for a retest of support or a confirmed breakout above $280 with volume. The data shows the bulls are in control, but they need to clear that $280 hurdle to unlock the next leg of this rally. Keep your stops tight, trust the options flow, and let the AI narrative do the heavy lifting.
