Other jurisdictions not so much. There are various scrapers available to obtain generic race card information[2] and APIs from some bookmakers/exchanges.[3]
A couple of years ago I read an article lamenting the lack of open data in horse racing, which still largely holds true today. Unfortunately, I can't find the article now (it was either on the Paulick Report or Bloodhorse website), but here's a more recent one from May this year calling for more open data.[4]
In fact, a question was asked on HN a couple of years ago about an open horse racing database and as far as I know the answers there are still valid.[5]
In general, there is data available for US, UK, IRE, Australian racing (the main jurisdictions) but they have to be paid for.[6][7][8][9]

Several orgs, including Equibase (US-based, the gate keeper of a good portion of handicapping data) will regularly send cease and desist orders to people who attempt to automate aggregation of data even with free, publicly available content. That's at least half the reason PDFs are used when customers purchase data access, to make aggregation harder (you should see some of the white space, character encoding fuckery they use to throw off aggregators).
I suppose some of this often depends the quality of the data as well. Most data entry happens at the track during the race by a human, none of the data collection about races or the horse stats are collected by a computer, it's 95% hand entered. That also goes for pedigree information and other statistics including medications, weights, etc. And 100% of that is usually self-reported.
Much of the current handicapping in the industry is everyone trying to protect their personal mountains of data. Tech-minded people would love to provide open, controlled, API services so that people can do what they will with our mountains of data. But "giving it away for free" is a non-starter for the good ole boys at the top..
I was involved for a number of years with a UK based horse racing ratings service (handicapping if in the US). This service used to license their base data from the Press Association[1] and then run algorithms on top to produce the ratings.
There's certain things I can't say due to NDAs which are probably still in effect, but the cost of licensing this basic data was in excess of £10k per annum. So, unless you were a serious bettor or were looking to operate a service of some kind, it's beyond the pocket of most individuals.
Timeform in the UK also license some of their own proprietory data, via an API[2]. They've published some pricing on their website and you're looking at between £6k - £12k per year. This is just to access data which is available via their website for a subscription fee of £75 per month, but via their API.
There's even a specific UK organisation which apparently has the permission from the British Horse Racing Authority to officially licence key racing data. This is who sells the data to bookmakers, form guides, racing newspapers etc. They have a rate card published on their website.[3] Private, pro-punter? £8.5k per year please.
It's a bit of a rort really. Most of the data is "freely" available online or in the racing press, but if you want to access it any useable format, either build a scraper (good luck with staying on top of the website changes) or pay a stack to access things programmatically.

Almost all tracks publish result charts online for free along with race videos. If you want free, why not compile the data yourself? How long would DRF or Equibase exist if people could access their data for free?
I really do not care about the likes of DRF or Equibase and how long they will or won't exist. I think it is upon the industry itself to ensure this data is available free and easily accessible. Look at Hong Kong as the alpha example. Loads of free data, huge betting turnover, well funded industry.
DRF makes racing data easily accessible. If it was left to the tracks, which are independent entities (unlike NFL/NBA/MLB), an horseplayer would have to compile past performances from dozens of sources. The fields of a single day's race card may have run at 30 or more individual venues, in aggregate. Even if that data were free (well, the result charts and replay videos are already free, so technically this is already possible) if would take a ton of work to assemble it all in a digestible format -- which the DRF does for 6 bucks.
I don't believe HK offers free data that is not available from American tracks. There is no API, the result charts are less detailed than American tracks. If info was so freely available to everyone, how would someone like Bill Benter gain such a huge advantage? Why wouldn't he replicate his methods in the US? Probably because the US makes MORE data available.
Also, it's important to make the distinction between editorial content (analysis, predictions, subjective descriptions of a horse or jockey performance) and empirical information (horse weights, medication, surface conditions, weather, placements, jockey-horse combo win-rates, etc).
The DRF sells its speed ratings as well as analysis of pedigree and past performances. There's value in that and it definitely justifies the cost of their publication and the other publications that perform similar work.
The critical issue with your stance is that users have no options to aggregate their own data easily. The free PPs Equibase offers have been scrapped before and I know of several specific instances where the creators of those scrappers were sent cease and desist for collecting the information Equibase otherwise provides for free. Even to Github to remove the repository that contains the code.
I'm not advocating scrapping (please don't scrape sites like that) but there isn't any industry interest in providing modern consumable data. Wouldn't it be in Equibases best interest to put that information behind an API and sell access to the public? The industry actively discourages using publicly available data.
Benter used this himself, as detailed in his paper 'Computer Based Horse Race Handicapping and Wagering Systems: A Report' - https://www.gwern.net/docs/statistics/decision/1994-benter.p...
