NEW YORK, July 10, 2026, 08:30 EDT
Micron Technology NASDAQ:MU slipped 1.7% to $974.57 in premarket trade at 8:04 a.m. EDT, paring some of Thursday’s 4.5% jump. The memory-chip maker announced plans to boost U.S. investment by over $50 billion. That surge on Thursday lifted Micron’s market cap by roughly $48.4 billion, almost the same as the planned spend.
PHLX Semiconductor Index, or SOX, rose 3.06% on Thursday, but Micron’s stock outperformed that. Strip out the sector’s move and Micron alone added 1.46 percentage points, about $15.7 billion. That difference is in focus as SK Hynix (NASDAQ:SKHYV; KRX:000660) kicks off when-issued trading in New York on Friday, ahead of regular settlement.
This is just a rough estimate, not an official attribution. Micron trades with more volatility than the index, and news about the company often moves chip stocks. But when you do the math, most of Thursday’s gain—about two-thirds—looks like general chip buying, not just a straight reaction to the new factory promise.
| Thursday’s signal | Value |
|---|---|
| Micron finished at | $991.64 |
| Micron daily change | +4.52% |
| SOX daily change | +3.06% |
| Micron outperformed SOX by | +1.46 points |
| Micron estimated added market cap | ~$48.4 billion |
| Estimated sector-adjusted gain | ~$15.7 billion |
| Planned U.S. investment raised | More than $50 billion |
Micron now puts its U.S. chip and tech investment above $250 billion through 2035, lifting its earlier $200 billion target. The company wants to reach 40% DRAM output in the U.S. Its Clay, New York, build started pouring concrete over a quarter earlier than planned.
Micron Technology has set up a separate supply-chain plan worth up to $3 billion, which includes $500 million in financing for a Texas factory that will make 300-millimetre silicon wafers—the basic discs chips are made from—and includes a 10-year supply deal. “Securing a reliable supply of critical input materials is essential to supporting Micron’s long-term growth and technology roadmap,” procurement chief Ben Tessone said.

Micron’s near-term spending plan is small compared to the cash it’s bringing in. The company posted $18.3 billion in adjusted free cash flow last quarter, and said it has $30.2 billion in cash, investments and restricted cash. The announced $3 billion spending plan is about 16% of quarterly free cash flow. The longer-term plan’s more than $50 billion increase would burn through about 2.7 quarters of current free cash flow. Micron hasn’t said how much it plans to spend per year. Memory cash flows are volatile.
BofA Global Research analyst Vivek Arya kept his Buy rating and $1,550 target. “We believe the market is underestimating the transition toward longer-duration agreements and more predictable pricing,” Arya wrote. He sees global cloud and AI infrastructure spending hitting about $1.5 trillion in 2027, with memory making up 35% to 40% of that. Barron’s
SK Hynix’s U.S. debut puts a direct peer in front of American investors at a lower price. The South Korean chipmaker brought in $26.5 billion from its sale of American depositary receipts, priced at $149 apiece. SK Hynix is the top producer of high-bandwidth memory, a stacked chip used for fast data transfer to AI processors. The stock trades at about 5.8 times forecast 12-month earnings, below Micron’s roughly 7 times.
| Investor comparison | Micron | SK Hynix |
|---|---|---|
| U.S. trading status | Regular Nasdaq ticker | Nasdaq ADR started on when-issued terms |
| Forward P/E | Near 7.0x | Near 5.8x |
| Latest capital move | Pushed over $50 billion into U.S. plan | Secured $26.5 billion through fresh equity |
| Main positioning | U.S. production focus, wider product range | Bigger in HBM, tight control on supply |

The trade could also go the other way. If AI infrastructure spend slows or if production gets out in front of demand, memory prices and margins might fall before Micron’s new plants deliver real returns. Daniel Newman, CEO of Futurum Group, said in a true “AI winter,” Micron’s bigger spread and U.S. base could make it “the relative safe haven,” but if the downturn is lighter, SK Hynix might come out ahead since more of its supply is locked in.

At Friday’s open, what matters more than Micron reclaiming $991.64 is whether the stock keeps its valuation premium after U.S. investors get access to SK Hynix. If Micron keeps lagging the SOX, that could mean capital is shifting to the new SK Hynix listing. If Micron holds up, it may show investors still value its U.S. manufacturing and contract-backed cash flows.
