Where will 2026 rank among the hottest years on record?
2026 looks very likely to finish among the very warmest years ever, but the case for it finishing first is still not ironclad. I would price a meaningful Yes chance, though below the current market level.
Analysis
The strongest argument for Yes is that 2026 has stayed unusually hot through the middle of the year, with July matching the warmest July on record in one major dataset and strong regional heat reinforcing the global signal. That kind of sustained warmth matters because the annual ranking is based on the full-year average, and a year that is already near the top by mid-August has a real path to finishing first if late-year months remain elevated rather than cooling sharply.
At the same time, the current evidence does not make 2026 a runaway favorite. NOAA-style year-to-date tracking still has the year around third-warmest through July, and outside summaries point to a finish somewhere in the top five, most likely third or fourth, which is consistent with a very hot year but not necessarily a record breaker. In other words, the baseline is strong warmth, but the margin needed to overtake prior record years is still uncertain and may be modest or nonexistent if the next several months normalize.
The market is also balancing competing model signals. Berkeley Earth’s updated probability estimate implies a materially higher chance of a record than it did earlier in the summer, and that kind of upward revision usually reflects a meaningful shift in expected global conditions. However, the fact that another prominent view still favors second or third rather than first suggests the market may be overconfident at the current price. My assessment is that Yes is more likely than not, but not by nearly as much as the current implied pricing suggests.
Arguments
For
- Arguments for Yes: Midyear temperatures are already at record or near-record levels, which gives 2026 a credible path to finish first.
- Arguments for Yes: Updated warm-year probability models have recently shifted upward, implying the year is becoming more competitive for the top spot.
Against
- Arguments against Yes: Year-to-date comparisons still place 2026 behind the very hottest benchmark years, leaving a gap to overcome.
- Arguments against Yes: Independent outlooks still describe a top-five finish as more likely than an outright number-one finish.
Key drivers
- Persistent extreme global temperatures through mid-2026 keep the annual average close to record territory.
- A strong El Niño-like warming signal raises the chance that late-year months stay hot enough to lift the annual rank.
Risk factors
- If the final months cool even modestly, 2026 could slip behind one or more recent record years.
- Current year-to-date rankings suggest 2026 may be competing more for second or third than for first.
Scenarios
Best case
Late 2026 stays persistently hot across the globe, the annual average edges past all rivals, and the year finishes as the new hottest year on record.
Most likely
2026 remains one of the hottest years ever, but the final ranking lands just below first, with second or third being the most plausible outcome.
Worst case
Late-year temperatures normalize enough that 2026 is overtaken by one or more prior record years and ends up second, third, or fourth.
