Altera Files Confidentially for U.S. IPO, Testing Intel's Hidden Asset Value

Altera has confidentially filed for a U.S. IPO, according to a September 15 announcement, in an offering that Reuters previously reported could raise more than $2 billion. Silver Lake owns 51% of the programmable-chip company after investing $4.46 billion for control, while Intel Corporation (NASDAQ:INTC) retains the remaining 49%.

The listing would put a fresh market price on an asset Intel has only partially monetized. Intel bought Altera for $16.7 billion in 2015, then separated the business and sold control to Silver Lake last year. An IPO would create a new, publicly visible valuation for Intel's retained stake.

That matters because Intel needs capital. Its foundry expansion demands enormous spending while the company still works to restore competitiveness in conventional CPUs and advanced manufacturing. A strong Altera valuation could crystallize value in an asset that investors currently bury inside Intel's much larger turnaround story.

The AI question

There is a catch. IPO appetite for anything carrying an AI label can run ahead of operating reality. Altera makes programmable chips across industrial, communications, aerospace and data-center markets. Management has projected mid-20% revenue growth in 2026, but investors will have to judge for themselves how much of that growth is genuinely AI-driven.

The renewed investor interest in FPGAs comes from artificial intelligence giving the sector a fresh narrative, just as Altera heads back toward the public market.

The AMD benchmark

The most useful strategic comparison is Advanced Micro Devices (NASDAQ:AMD), which bought FPGA leader Xilinx in 2022 and integrated programmable silicon into a much broader data-center portfolio. Xilinx gave AMD FPGAs, adaptive SoCs and software that can sit beside its EPYC CPUs and Instinct accelerators. That bundle can prove attractive in heterogeneous systems.

The bear case, however, is that AMD paid heavily to assemble that portfolio. Integrating multiple product families does not guarantee that every FPGA workload migrates into AMD's ecosystem. Altera, by contrast, returns to market as a standalone pure play — with the pricing of that independence about to be tested.

Funds moved into both chipmakers

Hedge fund positioning shifted in the second quarter. Insider Monkey counted 138 hedge funds holding Intel in Q2, up from 112 in Q1. AQR Capital Management held about 10.7 million shares after trimming its stake by roughly 7%. AMD ownership jumped to 164 funds from 134, while Marshall Wace held about 3.9 million shares after a modest increase.

Short interest in Intel stood at approximately 152.2 million shares on August 31 — about 3% of the public float.

If the IPO prices well, Intel gains a marked valuation on its 49% stake and a potential funding lever for its foundry buildout. If it prices weakly, investors will have their answer on how much of the FPGA recovery is real AI demand rather than relabeled growth.
