Anthropic’s AI Shockwaves: Why the New AI Powerhouse Is Spooking Global Markets

If you want to see what happens when the market’s favorite narrative gets a cold splash of reality, look no further than this week’s tech-led selloff across Asia. The culprit? Not another regulatory crackdown or a rogue central banker, but an AI startup that most retail traders couldn’t pick out of a lineup: Anthropic. In a week that saw South Korea’s market regulator forced to hit the pause button and Indonesia’s Moody’s outlook cut spark a regional domino effect, the real story is how Anthropic’s sudden leapfrogging in the AI arms race has traders everywhere questioning the entire capex-fueled tech boom.

The headlines screamed about Indonesia’s -2% plunge and South Korea’s circuit breaker, but the undercurrent was pure AI anxiety. As reported by the Wall Street Journal, Anthropic, once the perennial bronze medalist in the AI Olympics, has surged ahead with a business-focused, safety-first approach that’s winning over enterprise clients and, crucially, spooking the mega-cap incumbents. If you thought the AI trade was just about Nvidia’s next quarterly beat or Microsoft’s cloud margins, this week’s price action says otherwise. The market is waking up to the fact that the AI arms race is not only expensive, it’s unpredictable, and the new winners aren’t always the ones with trillion-dollar war chests.

The facts are hard to ignore. South Korean equities extended their losing streak, with the KOSPI down sharply as investors dumped tech names en masse. Indonesia’s stock market, already reeling from Moody’s outlook cut, saw another wave of selling that dragged the IDX Composite below key support. Meanwhile, the tech-heavy XLK ETF sat frozen at $135.6, a picture of indecision as traders digested the implications of Anthropic’s rise. The AI trade, which has powered global markets since October 2022, is suddenly looking fragile. Even the usually unflappable U.S. software sector wasn’t immune, with a deepening selloff into the close as Bloomberg reported.

What’s different this time? For starters, the AI capex narrative is starting to feel a bit like 2018’s blockchain-for-everything mania, only with more zeros attached. Companies are throwing billions at AI infrastructure, but the market is now asking the uncomfortable question: Who actually captures the value? Anthropic’s focus on business clients and a more measured approach to model deployment is a direct challenge to the “bigger is always better” philosophy that’s dominated the space. That’s not just an existential threat to the incumbents, it’s a direct hit to the capex-driven growth story that’s underpinned tech valuations for the past two years.

If you’re looking for historical parallels, think back to the dot-com bubble’s late stage, when every company was suddenly a “tech play” and capital was allocated with the subtlety of a toddler at a candy store. The difference now is that the sums are larger, the players are more sophisticated, and the feedback loop is faster. When a single AI upstart can move the needle for trillion-dollar companies, you know the game has changed. The market’s reaction this week is less about Anthropic itself and more about the realization that the AI trade is no longer a one-way bet.

Strykr Watch

Technically, the XLK ETF at $135.6 is the market’s Rorschach test. Bulls will point to the lack of a breakdown as evidence of underlying strength, while bears see a classic distribution top. The KOSPI’s recent breach of its 200-day moving average and Indonesia’s tumble below key support levels are warning signs that the tech unwind could have further to go. Watch for XLK to hold (or lose) the $135 level, below that, the next stop is the $130 zone, which coincides with the ETF’s 100-day moving average. On the upside, a sustained move above $140 would signal that the AI panic has been digested, at least for now.

The real tell will be in the software names that have led the AI charge. If they can’t find a bid soon, the risk is that the unwind accelerates, dragging the broader market with it. Keep an eye on volume spikes and options activity, if the put/call ratio starts to climb, that’s your cue that the pros are hedging for a deeper correction.

The risks here are obvious, but worth spelling out. If the AI capex narrative collapses, the knock-on effects for everything from cloud infrastructure to semiconductors could be severe. A hawkish surprise from the Fed, especially with Kevin Warsh’s nomination in the mix, would only add fuel to the fire. And if Asian markets can’t stabilize, expect global risk appetite to take another leg lower.

On the flip side, the opportunity is clear for traders who can separate the signal from the noise. If the market is overreacting to Anthropic’s rise, there will be bargains in the tech sector, especially among the names with real, defensible moats. Look for relative strength in the software names that aren’t as exposed to the capex arms race, and be ready to pounce if XLK finds support at $135 or lower. For the brave, selling volatility into panic spikes could be a lucrative play, provided you’re nimble with your stops.

Strykr Take

This isn’t the end of the AI trade, but it is a wake-up call. The days of blindly chasing every capex headline are over. Anthropic’s rise is a reminder that innovation is messy, unpredictable, and often comes from unexpected places. For traders, the message is clear: Stay nimble, respect the technicals, and don’t get married to last year’s narrative. The next leg of the AI story will reward those who can adapt, not those who cling to the past.
