Gartner expects more than half of quantum-computing startups to fail by 2030, as a crowded market struggles to turn early promise into enough commercial revenue. The forecast sets a hard question for a field attracting investment while broad commercial usefulness remains elusive.

What happened
The Register reports Gartner estimates there are between 200 and 300 quantum startups competing in a market forecast to generate $1.1 billion in worldwide revenue in 2027, up from $869.9 million forecast for 2026. Gartner says customers are likely to reject technologies that fail to achieve fault-tolerant quantum computing, where calculations remain reliable despite hardware errors.
The report also says enterprises are beginning to invest and build expertise, even as practical applications remain limited. Gartner forecasts public-sector quantum spending of $245 million in 2027, with banking, finance and insurance expected to become the largest spending sector in 2028, at $289 million. These are Gartner forecasts reported by The Register, not realised results.
Why it matters
A market can attract early customers and still leave many suppliers fighting over a relatively small pool of spending. If Gartner’s forecast is right, technical progress alone will not guarantee that today’s startups survive long enough to turn it into a business.
For buyers and investors, the distinction is between experiments that build useful expertise and products that deliver reliable, commercially valuable computing. The report offers a forecast, not a verdict on which companies will make it.
Our read
This is a useful reality check for a sector where the word “quantum” can make a funding round sound like the hard part is already done. Gartner’s numbers suggest the next test is whether companies can show practical value, not merely a plausible route towards it. The Register also reports Gartner’s view that early signs of business advantage are emerging, so this is not a forecast that the field has no future.
What to watch
- Whether quantum companies demonstrate reliable, fault-tolerant systems.
- Whether reported enterprise trials turn into sustained commercial use.
- How actual 2026 and 2027 spending compares with Gartner’s forecasts.
Discussion spark: Should investors and public funders back a broad field of competing quantum startups, or concentrate support on the few approaches closest to fault-tolerant, commercially useful systems?
