Biggest Movers This Quarter
The largest swings this quarter, up or down
This list tracks the largest rank swings of the quarter in either direction, and roughly half of it is falling rather than rising — a sharp decline is exactly as newsworthy as a sharp rise, and this list refuses to only cover good news. Each entry states plainly whether it moved up or down and why, rather than burying a decline in vague language. Some of these swings will hold for years; others are likely to reverse by the next update, and the note on each entry says which looks more probable.

The top three
Leading the list
Rank 01Editor’s pick
DeepSeek
DeepSeek · open-weight models · 2023
An open-weight model that matches GPT-4-class reasoning on many benchmarks at a fraction of the API cost, which is why it forced every major lab to cut prices within weeks of release.

Humane AI Pin
Humane · wearable AI device, launched April 2024 — assets acquired by HP, 2025
A screenless, voice-and-projection wearable meant to reduce phone dependence, the AI Pin shipped to overwhelmingly negative reviews citing overheating, sluggish response times and a subscription fee on top of an already high device price; Humane sold its core assets to HP roughly a year after launch.

Northvolt
Swedish EV battery maker · filed for bankruptcy, November 2024
Once positioned as Europe’s best hope for a homegrown battery-manufacturing champion and backed by billions from investors including Volkswagen and Goldman Sachs, Northvolt filed for Chapter 11 bankruptcy protection after production delays and quality problems it was never able to fully resolve.

- Rank 13. Anthropic. Score 76.4 out of 100.1Down 1
Anthropic
Artificial intelligence · Founded 2021
Anthropic was founded explicitly by researchers who left OpenAI over safety disagreements, and that origin story still shapes hiring — the company screens hard for people who want the safety mission, not just the compensation.
76.4/100 Top 49 score - Rank 14. Reykjanes Peninsula. Score 74.5 out of 100.—No change
Reykjanes Peninsula
Iceland · recurring volcanic eruptions since December 2023
A series of volcanic eruptions near Grindavík has repeatedly forced evacuations and closed the nearby Blue Lagoon spa multiple times since late 2023, and the ongoing seismic activity has made this stretch of Iceland’s tourism industry one of the more disrupted travel stories of the past two years.

74.5/100 Top 49 score - Rank 15. Suno. Score 72.9 out of 100.1Up 1
Suno
Suno · music generation · 2023
Full songs with structure, not just a loop — verses that build into a chorus that actually resolves. The lyrics are the weakest layer; the composition and vocal performance are not.
72.9/100 Top 49 score - Rank 16. Peloton. Score 70.7 out of 100.4Down 4
Peloton
Connected fitness equipment and subscription company
Peloton’s pandemic-era boom gave way to a prolonged demand hangover, multiple rounds of layoffs and a revolving door of leadership, though the most recent quarters show the decline stabilising rather than continuing to steepen — a smaller, steadier business rather than the growth story it once was.

How this list is scored
Four criteria, weighted before the first entry
Movement is tracked as signed rank change on each entry’s home category list; a large negative number is treated with exactly the same editorial weight as a large positive one, not downplayed.
- Magnitude of movement 30%
- Absolute size of the rank swing, up or down, over the comparison window.
- Clarity of cause 25%
- How well the underlying reason for the move can be documented and sourced.
- Real-world consequence 25%
- Whether the move reflects a change with genuine downstream impact, not just news-cycle noise.
- Durability of the new position 20%
- Likelihood the move holds rather than reverting by the next update.
Questions
About this ranking
Why include companies that are failing, not just succeeding?
A collapse is exactly as significant a move as a breakout success, and this list would be a worse editorial product if it only tracked good news. Northvolt’s bankruptcy is as much a "biggest mover" as BYD’s growth.
How is "likelihood the new position holds" judged?
Against precedent. A bankruptcy filing is treated as durable; a single bad product cycle or a weather-driven disruption is treated as more likely to reverse.
Do the same entries reappear quarter to quarter?
Rarely by design. An entry that has already made its big move typically drops off in favour of the next quarter’s sharpest swings, up or down.
How often does this list update?
Weekly. "This quarter" in the title refers to the comparison window each rank change is measured against, not the update frequency.
