Should IBM spin off its quantum computing division after its worst trading day in nearly 60 years? Here's the actual case on both sides

[Max_42]

IBM's stock fell just over 25% on July 14, its worst single session in at least 58 years of trading records, wiping out roughly $67 billion in market value after CEO Arvind Krishna pre-announced weak second quarter numbers, revenue up just 1% with mainframe revenue down 42%. That crash has reopened a genuine strategic question, whether IBM Quantum, arguably the company's strongest frontier technology asset, is worth more spun out as an independent company than held inside a conglomerate the market has stopped valuing at a growth multiple

The case for spinning out rests heavily on the Quantinuum precedent, Honeywell's quantum unit raised $1.68 billion in a June Nasdaq IPO priced at $60 a share with an order book more than 20 times oversubscribed, now trading at roughly $17.6 billion in value while Honeywell retained about 48% voting control. IonQ trades near a $20 billion market cap against 2026 revenue guidance of just $260 to $270 million, a sales multiple pure play quantum companies command that a diversified conglomerate simply cannot capture for the same assets. IBM Quantum, by contrast, has more than 90 deployed systems worldwide, the dominant Qiskit software ecosystem, and a credible roadmap toward its 2029 Starling and 2033 Blue Jay fault tolerant systems, yet is valued at effectively zero inside IBM's current stock price

The case against separation is just as real though. Quantum remains capital hungry and pre-revenue at meaningful scale, and IBM's balance sheet currently funds a roadmap that a standalone company would have to finance in public markets that can turn hostile fast, as Quantinuum's own disclosed accumulated deficit shows. The IBM Quantum research pipeline is also deeply entangled with the rest of IBM Research, and this month's acquisition of HRL Laboratories, adding silicon spin qubits alongside IBM's existing superconducting program, deepens that entanglement further rather than simplifying it. IBM has already accepted the separation logic partially, setting up its Anderon chip foundry as a standalone company with its own governance, which suggests the board understands some quantum assets work better outside the parent structure, leaving the open question of whether that logic eventually extends to the whole division

The Anderon foundry already being spun out as its own standalone company is the detail that actually tips me toward believing this eventually happens to the whole quantum division too, the board has already accepted the logic once

[Reuben82]

IBM Quantum being valued at effectively zero inside the stock while IonQ trades at 75 times forward revenue is such a stark illustration of exactly what a pure play multiple versus a conglomerate discount actually looks like in practice

[BeckyLynch]

Worth remembering Quantinuum's own accumulated deficit on the way to its IPO shows going independent doesn't magically solve the capital hungry, pre-revenue problem, it just moves who's funding that gap

[Kieran88]

This is a well argued piece that takes both sides seriously rather than just building toward an obvious predetermined conclusion, appreciate the explicit financial disclaimer too given how speculative this whole sector still is

[Amber Tiger]

The government and defense buyer angle is underrated here, agencies increasingly seem to prefer dealing with focused quantum specific counterparties rather than a sprawling conglomerate, that's a real commercial argument for independence

[Hawk38]

I lean toward this happening eventually but not soon, boards rarely sell an asset at the bottom of a drawdown, waiting until Starling actually ships in 2029 would likely command a far better valuation

A successful IBM Quantum spinoff putting pressure on Google to consider the same move for its own quantum program buried inside an advertising and cloud company is an interesting knock on effect worth watching for

The frontier halo theory, quantum as a shop window pulling customers into IBM's wider consulting and cloud business, is a real strategic logic even if the actual conversion evidence for it is thin, that's probably the strongest argument for holding on
