Preseen forecasts a 23% increase in real terms between 2026 and 2030, with an 80% range of +7.5% to +39.2%.
After 31 consecutive years of increases, the question is less whether spending will grow and more how fast.

Forecast Peek 👀

1/5
South Asia leads the forecast with 8.2 expected cities, followed by Africa (5.8) and Latin America and the Caribbean (2.3).

Climate change, population growth and water demand push the count up. Better infrastructure and water management could keep it lower.
The model gives a 10% chance of 40 or more cities.

Forecast Peek 👀
Are aliens visiting Earth? 👽
Preseen gives just a 1.6% chance that any UFO sighting will be confirmed as intelligent extraterrestrial visitation by 2100.
1/4
The most likely path to YES isn't another blurry UFO video. It's discovering a probe or other extraterrestrial technology already near Earth and proving where it came from.
3/4
Better telescopes and detection tools could help, but finding something unusual isn't proof of aliens.

Forecast Peek 👀
When will a city first carry more than 1 million commercial eVTOL flying taxi passengers in a year?
Preseen’s median forecast: December 2036.
9% chance by 2030, 70% by 2040, and 88% by 2050.
1/5
Dubai is building its flying taxi network, but its airport vertiport has an advertised design capacity of 170,000 passengers a year.
In China, EHang is running trials in Guangzhou and Hefei, but commercial passenger operations have yet to reach scale.
4/5
Why 2036?
Certification, fleet expansion, infrastructure and passenger demand all take time.
What matters next isn't another test flight, but whether cities can turn early launches into reliable, high-volume transport.
