Anthropic's $2T IPO Is a Test for Samsung and SK Hynix

The IPO That Could Redraw Korean Markets

Anthropic is preparing its initial public offering this fall, with a target valuation as high as $2 trillion and fundraising projected at around $100 billion. If those numbers hold, the company would leap straight into the stratosphere of global market capitalization — and the ripple effects could hit Korean semiconductor stocks harder than most investors realize.

Samsung Electronics and SK Hynix have built their latest growth narrative on AI infrastructure demand. They supply the high-bandwidth memory and server DRAM that data centers need. But Anthropic’s listing opens a direct channel into the AI model layer that these chipmakers can’t access. That changes the calculus for every fund weighing where to park money.

The structural tension here runs deeper than a single deal. Korean chipmakers have spent years convincing the market that their HBM division — particularly the HBM3E chips used in NVIDIA’s AI accelerators — represents an irreplaceable node in the global AI supply chain. SK Hynix currently holds roughly 80% of that market share. Samsung is scrambling to close the gap. The thesis has worked: both stocks have re-rated significantly from their post-pandemic lows. But Anthropic’s IPO introduces a competing thesis — one that rewards investors for buying the brain, not the battery.

Who Wins, Who Loses

A successful IPO is arguably the more dangerous outcome for Samsung and SK Hynix — not because the deal is weak, but because it validates a simpler investment logic. If investors can buy into frontier AI model companies directly, the roundabout path through semiconductor suppliers starts to look unnecessarily complicated. Capital migrates toward the origin point of the thesis.

Kim Min-gyu at KB Securities noted this dynamic bluntly: Korean investors are likely to flock to the Anthropic offering regardless of how it performs. He pointed to the SpaceX IPO as precedent — Korean capital surged into the deal even when the won-won exchange rate was unfavorable. Retail investors here have shown repeated willingness to chase high-profile tech listings overseas.

A botched or underwhelming IPO creates a different problem. Doubts about Anthropic’s $2 trillion valuation would inevitably spread to the broader AI sector. If the market rejects even this level of pricing for a company generating billions in annual recurring revenue, the bar for every AI company rises. And when skepticism about the AI investment cycle deepens, it flows downstream — to HBM and server DRAM — because those sectors trade on the same growth assumptions.

Either scenario is uncomfortable for Korean chip stocks. A successful listing siphons capital. A failed one undermines confidence in the entire AI hardware boom that has propelled these companies to record valuations.

The Second-Order Effects No One Is Pricing In

Beyond the immediate capital migration, there are cascading consequences that could reshape how the Korean market views semiconductor exposure going forward.

Consider the pension funds. Korea’s National Pension Service manages over $500 billion in assets and has been steadily increasing its allocation to US technology equities. An Anthropic listing gives NPS and similar institutions a cleaner way to gain AI model exposure without routing through Samsung or SK Hynix. That reallocation would be structural, not transient — pension capital moves slowly and tends to stay once committed.

Then there’s the options market. Korean investors have grown increasingly sophisticated in their use of LEVER stocks and weekly options tied to semiconductor names. If Anthropic’s IPO pulls liquidity away from those instruments, volatility in Samsung and SK Hynix could spike not from fundamentals but from derivatives positioning unwinding in thinner markets. The feedback loop between spot selling and options gamma could amplify downside moves well beyond what the underlying business warrants.

There is also the currency dimension. A strong performance by Anthropic could strengthen the dollar further, pressuring the won and making imported semiconductor equipment more expensive for Korean manufacturers. Samsung and SK Hynix already face margin pressure from rising fab construction costs in Texas and Pyeongtaek. A weaker won adds another cost headwind at a moment when they are trying to fund massive capital expenditure cycles.

On the flip side, a weak Anthropic IPO could accelerate a flight to quality within Korea itself. Investors might rotate from speculative AI model plays back into the perceived safer haven of established chipmakers — at least temporarily. That rotation would be emotional rather than rational, but markets rarely move on pure logic.

The Timing Problem

Anthropic’s IPO is scheduled for September or October. That places it squarely after the US midterms, adding a geopolitical layer to an already sensitive moment. Semiconductor policy has become one of the few areas where Washington can still move the needle on China restrictions, export controls, and allied supply chain coordination. A major IPO happening in this window means Korean chipmakers face two simultaneous uncertainties: market sentiment around AI valuations, and potential policy shifts from a newly configured Congress.

The midterms could produce a more aggressive posture on China tech restrictions, which would compress demand forecasts for Korean memory makers. Or it could produce gridlock that leaves the status quo intact. Both outcomes matter, and neither is friendly to a sector that still relies heavily on Chinese end-market demand — particularly Samsung’s foundry business, which has been losing ground to TSMC in advanced nodes.

There is also the question of investor sentiment toward Korean equities more broadly. The KOSPI has experienced periodic outflows as global funds recalibrate their emerging market allocations. An Anthropic IPO that captures headlines and capital could accelerate that drift, making it harder for Samsung and SK Hynix to command the premium valuations they have enjoyed over the past year.

The Valuation Question

The source material cites an ARR exceeding $650 billion. At a $2 trillion valuation, that implies a price-to-sales multiple of roughly 30x. Whether that multiple is justified depends entirely on what you believe about AI infrastructure spending trajectories. Companies like Palantir, Nebius, and Astera Labs already trade at elevated revenue multiples, which suggests the market is pricing in sustained hypergrowth. But those are individual cases. A $2 trillion Anthropic would be an outlier by design.

What matters more for Samsung and SK Hynix is whether the market accepts this pricing. If it does, the AI narrative strengthens — but capital still drains toward pure-play AI names. If it doesn’t, the entire sector faces repricing risk. The semiconductor stocks are caught in between.

One dimension worth watching is how Anthropic’s valuation compares to fellow AI infrastructure plays. Mistral, Cohere, and xAI have all raised capital at progressively higher multiples. If Anthropic commands a price that dwarfs these peers, it sets an anchor that makes every other AI company look either like a bargain or like a bubble — and Korean chipmakers will be swept into whichever bucket the market chooses.

What Happens Next

Watch the order book. If Korean institutional and retail demand overwhelms the offering, it signals that investors see direct AI exposure as preferable to indirect exposure through hardware suppliers. That is a structural shift in how the Korean market allocates AI-related capital — and it would weigh on Samsung and SK Hynix regardless of their fundamental performance.

Watch the post-listing price action. A sharp pop on debut reinforces the direct-investment preference. A muted or declining opening price triggers defensive rotation back into perceived safer plays — which, ironically, could temporarily benefit chipmakers even as it reflects broader anxiety about AI valuations.

The Korean retail investor — known locally as “개미” (ants) — is already moving. Their nervousness about Samsung and SK Hynix is not new. But Anthropic’s IPO gives that anxiety a specific focal point, and that focus is precisely what makes this moment different from previous rounds of AI-driven market turbulence.

Samsung and SK Hynix will report their earnings in the same window. Any stumble in HBM shipment guidance or server DRAM demand projections will be interpreted through the lens of the IPO outcome. A strong semiconductor quarter alongside a weak Anthropic debut could insulate the chip stocks. A solid chip report next to a soaring Anthropic ticker would tell a very different story — one where the best hardware company in the world still isn’t where the smart money wants to be.

The chips are on the table. Whether the money flows into Anthropic or stays in Seoul, the direction it takes will tell you everything you need to know about where the AI investment cycle stands — and whether the Korean semiconductor complex still commands the premium it has grown accustomed to.
