22% — the median of 6 frontier models, resolving by 2031-10-17.

Answer

Gemini (Google): 42% — Turns on whether an extreme pre-monsoon heat dome hits south-western Punjab with the right dry westerly wind alignment before 2030. Punjab's record is 48.8°C at Bathinda, while neighboring Rajasthan frequently tops 50°C, leaving less than a 1.3°C gap to bridge. Five summer seasons remain before the cutoff, giving multiple El Niño or drought-amplified windows for synoptic extremes. Dense irrigation in Punjab raises humidity and depresses sensible heat, reducing the likelihood of hitting 50°C compared to Rajasthan.

Answer

Claude (Anthropic): 12% — Hinges on IMD verifying a >50°C reading at a Punjab station by 2030, an extreme even amid warming trends. Punjab's historical max is around 48-49°C; crossing 50°C requires a record-smashing heatwave, not just incremental warming. Nearby Rajasthan/Churu has hit 50-51°C in rare extreme years, showing it's physically plausible in the region but not yet in Punjab specifically. Climate trends raise odds of extreme heat events over 5 years, but a precise >50°C verified reading remains a low-probability tail event.

Answer

GPT (OpenAI): 63% — It turns on whether an extreme pre-monsoon heatwave coincides with a verified Punjab station reading before 2030 ends. Punjab's official highs have approached 50C in severe northwest-India heatwaves, making a marginal record break plausible in four summers. IMD must observe and validate the reading; station siting, instrumentation checks, and short-lived peaks can prevent recognition. Warming raises tail-risk, but a weak El Niño/monsoon-timing pattern through 2030 would materially lower the chance.

Answer

Grok (xAI): 22% — A Punjab IMD station must log >50°C in one of the 2027-29 May-June heatwaves. Punjab’s verified all-time high sits near 49.4 °C (2016); no station has reached 50 °C despite 2016/2022/2024 extremes. Only three remaining pre-2030 summers exist; irrigation and slightly higher latitude keep Punjab cooler than Rajasthan’s 51 °C events. A strong El Niño plus a blocking high over northwest India would most raise the odds.

Answer

DeepSeek (DeepSeek): 22% — Punjab's record sits near 48C, so this needs a rare synoptic extreme plus a station siting that survives IMD scrutiny. IMD's Punjab record is roughly 47-48C (Amritsar/Bhatinda class); crossing 50C requires a heat dome plus pre-monsoon dry westerlies in May-June. IMD must verify the reading; nearby Pakistan's 53.5C (Jacobabad 2010) shows the regional ceiling, but Punjab stations sit further east with more moisture. Warming adds maybe 0.3-0.5C per decade, so baseline odds per year are low; four summers to 2030 gives roughly a fifth chance.

Answer

Qwen (Alibaba): 22% — Punjab's record sits ~2°C below 50°C; closing that gap requires an exceptional heatwave, not just trend warming. Punjab's verified IMD station records peak around 47–48°C; a 2°C jump in a single reading exceeds the ~0.3°C/decade regional trend, so it needs a standout synoptic event. Five summer seasons (2027–2031) give multiple shots, and 2024 showed Haryana/Delhi hitting 50°C+ just south of Punjab, narrowing the geographic gap. Would revise up sharply if a 2027 pre-monsoon reading hits 49°C+ at any Punjab station, signaling the threshold is within reach of normal variability.
