~ the obituary ~

fivethirtyeight was a thing i checked during us election cycles and not much in between. by the 2012 cycle i was a 28-year-old engineer in turkey watching the obama-romney race the way a tech-leaning outsider would, mostly through tech press and a couple of polling-aggregator sites. nate silver's name showed up as the one statistician who had called the 2008 vote with a tighter model than the cable networks. that was the version of 538 i first read.

nate silver started the blog on march 7 2008 as a side project from his baseball prospectus work. the method was a poll aggregator with a state-by-state probabilistic model, the name came from the 538 electors in the us electoral college. by the closing weeks of the obama-mccain race silver was calling each state's likely outcome with explicit confidence intervals, which was new at the time for a public-facing politics site. when the votes were counted in november '08 the model had been close enough to feel like a quiet upgrade on cable-tv punditry.

i was not really paying close attention by then, but anyway, the new york times licensed the blog in august 2010 for three years and moved it under nytimes.com/fivethirtyeight. that move gave silver a much wider audience for the 2012 forecast, which famously called every state correctly plus the district of columbia. by july 2013 espn had bought the brand outright and rebuilt it as a standalone site that covered politics alongside sports analytics. it sat under disney's espn arm until april 2018 when it moved over to abc news, also a disney unit.

this part you had to be in the us political-press orbit for, and i was only adjacent to it. nate silver left in april '23 after two-thirds of the staff were cut. g. elliott morris came in as data editor a month later. the remaining fifteen-person team kept publishing politics-only coverage through 2024 with very little staffing growth. abc news closed the site on march 5 2025 and folded the remaining election-tracker tools into the politics section of abcnews.com.

~ how it landed ~

the 538 method was straightforward enough on paper. you took every public poll and weighted it by the pollster's historical accuracy, then ran the result through a state-level simulation that produced a probabilistic prediction of the electoral college. silver was not the first person to do this in academia. he was the first person who packaged the output for a wide english-language readership through a daily blog with charts and a clear win-probability number. that win-probability number is the thing that survived him.

the 2012 election was the high water mark, with the model calling all 50 states plus dc against a cable-tv consensus that was treating the race as a tossup. the 2016 forecast was where things got more complicated. the model put trump's win probability at 29 percent on election morning, well above most competing forecasts but still treated as a miss because the model itself was widely read as predicting a clinton win. silver spent the next four years explaining that 29 percent was not zero.

~ the long tail ~

nate silver's april 2023 departure was the inflection point. the staffing cut took the political team from a couple dozen people down to fifteen and pulled the sports-analytics arm out of the brand entirely. silver started silver bulletin on substack as a continuation of his own forecasting work, morris started strength in numbers as a competing newsletter. the post-2023 fivethirtyeight had the brand and the archive but very little of the team that built either.

by then disney had cut several abc news properties under bob iger's broader cost-reduction effort and fivethirtyeight had ended up on that list. the march 5 2025 closure was a single-day announcement, the fifteen staffers walked out that morning. the archive of fivethirtyeight.com stayed up under abcnews.com for about fourteen months before being merged into the politics section in may '26, with the original urls redirecting away from the 538 brand entirely.
