NYC population change (July 2025 – July 2027)?
I rate a modest NYC population increase over July 2025 to July 2027 at 33%, below the market. The most likely outcome is still a slight decline, with positive immigration and job growth offsetting but not fully overcoming housing and domestic out-migration pressures.
Analysis
The evidence points to a city that is stabilizing but not yet clearly back in sustained growth mode. A reported loss of about 12,000 residents in 2025 suggests the recent trend was at best flat and possibly negative, while Manhattan rents around $5,000 and broader affordability pressures continue to push households out or prevent new household formation. That makes a small population increase over the full July 2025 to July 2027 window possible, but not the default case.
There are real offsets on the positive side. New York State still drew substantial immigration from abroad, the metro labor market added jobs through mid-2026, and public-safety conditions have improved, all of which support retention and in-migration. Those factors matter because the market only needs a relatively modest net gain to land in the 0.01% to 0.99% band, so the bar is not especially high.
Even so, I think the market is somewhat too optimistic on the Yes side. To clear this specific bucket, NYC needs two years of cumulative gains despite persistent high housing costs and ongoing domestic migration leakage, and the current data do not yet show that kind of durable upswing. My independent view is that the slightly negative range is still more likely than a small positive one, with the market giving too much weight to immigration and city vitality relative to affordability constraints.
Arguments
For
- International migration remains a meaningful offset to domestic out-migration and can support net growth.
- The metro economy is still adding jobs, which improves retention and attracts some new residents.
Against
- The latest 2025 trend signal is negative, which makes a two-year positive turn less likely.
- High rents and constrained housing supply continue to discourage household growth and encourage departures.
Key drivers
- Recent population data and trend proxies point to flat-to-slightly negative momentum entering the measurement window.
- International inflows and job growth can support a modest rebound if they persist through 2027.
- Persistent housing affordability pressure is the main brake on sustained household growth.
Risk factors
- Official population estimates could revise upward if recent losses were overstated by proxy data.
- A stronger-than-expected immigration cycle or labor-market resilience could push the city into the small-growth band.
Scenarios
Best case
Immigration stays strong, job growth continues, and the city narrowly ends the window with a small but clear population gain in the target range.
Most likely
NYC remains close to flat but slightly negative over the window, with gains from abroad and employment mostly offset by housing costs and outbound moves.
Worst case
Domestic out-migration and affordability pressures dominate, producing a modest decline that falls in the 0-0.99% or 1-1.99% decrease buckets.

Will Stripe acquire any part of Paypal in 2026?
AI7%MKT67%Edge-60HypedI think a Stripe acquisition of any part of PayPal in 2026 is very unlikely, despite the market pricing it as a strong possibility. The main reason is that this would be a large, strategically odd, and likely antitrust-sensitive transaction with little visible evidence supporting it.

Will OpenAI or Anthropic IPO first?
AI38%MKT93%Edge-55HypedI think OpenAI is substantially less likely than the market implies to IPO before Anthropic. The stronger read from the current evidence is that Anthropic has a modest but real timing edge, so I price the Yes outcome well below the market.

"Spider-Man: Brand New Day" 3rd Weekend Box Office (Lower Strikes)
AI64%MKT10%Edge+54Hidden GemA third weekend above 66 million is a very high bar, even for Spider-Man, so I lean toward Yes. The main reason to doubt that view is that this franchise can occasionally hold far better than a normal blockbuster if audience demand stays unusually strong.
