24 alternatives to Prediction Market for Trump's likelihood of pedophilia
Hey HN, I have been working on using the info-gathering and truth-seeking properties of the markets to get more honest reporting on all sort of things. The idea is to have a market game where people can wager a fake currency on what think is true and then, the citizen reviews the crowd-sourced information and makes a judgement about which position has the best case. It is crowd-sourced journalism with a market game. Please let me know what you think and my email is [email protected], if you have any questions.

Hi HN! Excited to show off the project we've been working on for the last couple months. We started with an idea for a crazy twist on prediction markets: You come up with a question for traders to predict, and then decide the outcome yourself. For example, you could create a market on “Will my date with [X] go well?” Anyone can bet on it, and the bets create a forecast on the chance your date goes well. After the date is over, you get to judge the result and reward the traders who picked the correct side. There are so many ways for this mechanism to go wrong: the creator of the market can be…

We've set up DeekSeek R1 with a system prompt that attempts to censor the word PRIVATEKEY from its response. If you can get DeepSeek R1 to output that string (not in the reasoning, but in the final response), the system will reveal a private key which contains $1000 USDC. You will have a 50 token limit in the input. We will have a series of contests, sponsored by AI researchers, in order to learn more about prompt engineering and how LLMs interact with real money. Good luck! Edit: The money was claimed! Thanks for playing all. You can still play for fun. Stay tuned for the next one! Stats:…

I haven't seen anything like this so I decided to build it in a weekend. How it works: You see a bunch of things pulled from Wikipedia displayed on cards. You ask yes or no questions to figure out which card is the secret article. The AI model has access to the image and wiki text and it's own knowledge to answer your question. Happy to have my credits burned for the day but I'll probably have to make this paid at some point so enjoy. I found it's not easy to get cheap+fast+good responses but the tech is getting there. Most of the prompts are running through Groq infra or hitting a cache…

Wanna impress your audience but don’t have enough money for a lambo? Fake it till you make it with a phony MRR dashboard! This might just look like I'm taking the piss, but I see this as an artistic statement about the latest trend of posting fake/embellished marketing content

I had an idea for this concept for a while and decided to build a little website around it. It's kind of a silly idea but I'm really curious to see how it plays out. If you're a particularly curious person, be warned. By submitting a payment to the game, you get to see how many other people were curious enough to play. You will be ranked based on your payment amount, and get to discover some interesting insights about the game's dynamics. Hope you like it

This project grew out of frustration of trying to find out the odds of a Hantavirus pandemic. When I went to search for it, I had to wade through sports gambling, and novelty markets that distracted me from just getting a really useful number with context to know if it was accurate. To solve this, my friend and I made mondael.com, which we're using to analyze, and visualize interesting prediction markets in the realm of: Geopolitics, Elections, Macro, Finance, Energy, and Science & Technology. The basic belief is that prediction markets can often move faster than news, but only if the data…

Hey HN, I built TrumpPosted to track the potential financial market impact of Donald Trump's social media posts in near real-time. It works by: Scraping his posts almost immediately. Sending the post content + metadata to an AI (Llama 3.3 70b via Groq) for analysis against specific financial subjects (stocks, bonds, crypto, or user-defined like 'Tesla stock'). The AI generates a headline, market sentiment score (0-100), summary, attitude analysis, and detailed commentary. Subscribers get email alerts within ~30 seconds containing this analysis tailored to their chosen subject. All analyses…

Hello hackers! I'm MattELab and I've built [SentientMerchant.com](http://sentientmerchant.com/) - Stock Market & Crypto News Sentiment As someone who owns multiple stocks, and perhaps you may hold or be interested in at least 1 stock and/or crypto, it was pretty overwhelming for me to keep up with the bombardment of news released 24/7 related to stocks and crypto that I hold as life gets pretty busy sometimes (e.g., academics, work). Hence, so often, I became unfazed and immune to reading stock/crypto news, which negatively impacted how I made investment…

I'm Arthur, and I wanted to share an MVP for Marqt.org, which lets you crowd-source the truth. John Stuart Mill said that "Truth emerges from the clash of ideas." In that spirit, Marqt brings two adversarial sides together to quantify truth and showcase the best arguments for each side. It is inspired by markets, where buyers and sellers discover a product's true price and update it dynamically. The ultimate aim is to build an open-source semantic knowledge base that represents the collective wisdom of humanity in real-time. If we can do this, I believe it can solve the problem of…

Hey HN! I RL-tuned an open-source LLM (gpt-oss-120b — 120B MoE, but only 5.1B active params) to predict "What will Trump do?" in any situation, trained on nothing but public news collected automatically from search queries. The trained model beats GPT-5, and both dataset and trained model are open sourced. Data generation: Generated 2,108 binary forecasting questions from just a search query and a date range using the Lightning Rod SDK (https://github.com/lightning-rod-labs/lightningrod-python-sd...). Questions are generated from historic news articles — like "Will Trump…

Hi HN! I built a proof of concept 'newspaper' that creates short news articles of today's current events with GPT. This is a very rough proof of concept but I can't help but think this concept is the future. I think we'll all have AI daily newspapers in whatever theme we want, covering any amount of information we want, with the ability to expand or contract article length instantly. Sharing just to get everyone thinking about this future. Thanks for reading!

Hi all, Been a while since I've posted and in the time since I have created a trading journal website where you can submit and track your trades with the USP of tracking your outgoings too. There has been a huge rise in the number of retail traders (me included) and a lot of people now have the very real possibility of quitting their day jobs and trading full time. I want to help people do that! It's still in very early stages and I'm releasing new updates daily but would be very grateful to get some other peoples feedback! Thanks in advance and hope you're all having a good day! :D
