NEW YORK, January 18, 2026, 21:21 EST — The market has closed.
- Rambus ended Friday trading 4.77% higher, closing at $107.99.
- U.S. stock markets will remain closed Monday in observance of Martin Luther King Jr. Day; normal trading picks up again Tuesday.
- Rambus will release its quarterly and full-year earnings on Feb. 2.
Rambus shares jumped 4.8% to close at $107.99 on Friday, pushing higher after a strong session earlier in January for the chip-and-IP firm. 1
U.S. stock markets will be closed Monday in observance of Martin Luther King Jr. Day, delaying the next momentum check until Tuesday. 2
Rambus plans a conference call on Feb. 2 at 2:00 p.m. Pacific time to go over its fourth-quarter and full-year 2025 results. The company specializes in memory-related chips and licenses “silicon IP,” which are the foundational designs chipmakers integrate into their products. 3
Chip stocks led gains in a volatile U.S. session on Friday, with the semiconductor index climbing 1.2%. The broader market, however, ended mostly flat ahead of the long weekend. Anthony Saglimbene, chief market strategist at Ameriprise Financial, noted investors would “take that as a win” with the S&P 500 still hovering near 7,000. Bruce Zaro of Granite Wealth Management pointed out that mid-January “tends to be pretty choppy” as earnings season heats up. 4
Memory stocks made headlines again over the weekend. Micron Technology revealed it has signed a letter of intent — a preliminary, non-binding agreement — to acquire a Powerchip Semiconductor fab in Taiwan for $1.8 billion cash. The announcement pushed Powerchip shares up nearly 10% on Monday. 5
Rambus has surged roughly 16% from its close of $92.90 on Jan. 12, marking gains across the past four sessions. On Jan. 16, it closed at $107.99, having touched a high of $108.39 during the day, per price data. 6
Rambus is zeroing in on demand for its memory-interface chips, driven by server builders and device makers chasing faster bandwidth. The company is also watching closely to see if licensing revenue stays strong as customers invest in next-generation designs.
The rally could quickly lose steam if memory prices drop or if chip earnings and forecasts don’t support the AI demand narrative. Thin holiday trading may also exaggerate price swings.
Trading picks up Tuesday, and all eyes will be on semiconductors—will they hold their gains or slip back after the pause? Rambus faces a key moment on Feb. 2, set to release earnings and outline its outlook. That report will likely set the tone for its stock.
