This article is focused on how I developed a system to manage prediction market portfolios and maximize expected value using battle-hardened strategies. The strategies I employed were profitable, but time intensive and incredibly hard to scale with a seven figure bankroll. At the peak of my prediction market era, I was monitoring dozens of markets simultaneously, scouring the internet for new info that could affect the odds of any one of the markets which I had a stake in. It became a full time job, which is fine if the surplus justifies it. In my case, it didn't.
Looking back at my tenure, I never actually specialized in one niche of markets. Anyone who tells you they're a full time trader doing one specific niche is either undercapitalized or lying. There simply isn't enough market breadth and density in one niche to justify the opportunity cost of avoiding other non-related markets. The best traders I encountered were incredibly sharp but most importantly, multi-faceted. They were able to effectively gauge different markets and price EV accurately by employing macro-level thinking heuristics to their systems, often in unique ways that most market participants have never even thought of doing.
That said, I focused mostly on geopolitics and internal affairs pertaining to the US. I avoided sports. Not because they're unsophisticated, but because the time sink and cognitive load made them structurally complex. They're also some of the most competitively priced markets due to saturation with regards to market participation. Way too many sharps.
I was what you might call a "bond mule". A bond mule is a trader that locks up capital on a market that's resolving soon, usually for a small premium. These types of markets have always attracted a particular type of trader, who would later become my favorite to match against. These traders, although differing in names, always shared the same three characteristics: undercapitalized, leverage-starved, and obsessed with convex payouts.
This type of trader would buy "YES" shares at 1-2c on "moonshots", outcomes that have an extremely low chance of paying out in their favor. They don't give too much thought about the actual probability of their preferred outcome materializing, only the potential payout. They also do not think about the trader on the other side who is stacking the other 98-99c to entertain their lotto fantasy.
That was my role. There were very few traders willing to tie up meaningful size for days or weeks to earn what looked like a trivial return. The mismatch between leverage seekers and well-capitalized liquidity providers created a persistent mispricing in several markets, for months on end. It also helped that I was betting on "NO" outcomes most of the time, which made the calculus even cleaner considering that ~70% of Polymarket events already resolve "NO".
The best part of it all was that I only provided leverage at expensive prices. Say there's a market about whether the dictator of some foreign shithole dies by next week. Let's say that he's (relatively) young with no publicly known health issues. He has an iron grip on his populace. A couple months ago, Polymarket might have had a market on him losing power by next week at 2%, whereas the actual implied odds might be well under 1%. As a bond mule, all you had to do was monitor that event and wait for your capital to get matched against a plethora of fish.
But what about the edge cases? Black swans do happen. They're bound to occur, and they were always factored into my models. I never went bust, but that wasn't because black swans don't exist, it was more because I had the proper framework to mitigate any potential fallout, which I'll touch on later.
One last note, the edge I listed above has gotten significantly smaller. Thanks to the slop posters, prediction markets have attracted a lot more fish, but also more well-capitalized traders happy to provide the same liquidity that I was providing. The easy premium is mostly gone.
The next meaningful edge will likely come from fading short term overreactions tied to Trump. I did a lot of that in 2025 and it was incredibly lucrative. I suspect it will be even more pronounced in 2026 as prediction markets start to account for that the fact that the current administration is more than willing to materialize gray-area clandestine operations. This should add a substantial premium to "YES" share prices for geopolitical markets, which in simpler words we can just call the "Trump can and will do crazy shit" premium.
You will have to pay for tools. This is not a free game. LLMs with their respective "deep research" modes are great for information synthesis, and especially useful when venturing into unexplored markets which you have no experience in trading. But they are not the end all be all. LLMs in nature optimize for the mean. And if you decide to offload all of your cognitive workload to a language model, you're literally indistinguishable from anyone else with the same $15 subscription.
News relays, especially pertaining to tradfi markets (as those usually publish groundbreaking news first), are great tools. There are many good free services out there. Enable notifications on your phone. A lot of it will be filler/non-consequential, and thats expected. Most importantly, you need to ensure that you're seeing the 1% of news that will impact your positions first. Despite what people might tell you, the landscape is still not that competitive for news trading. The juice (resting orderbook liquidity) is still not large enough to incentivize current news traders to pivot from crypto to prediction markets. And if you're lacking capital, this is a great way to build it. The downside of course, is that you will have to slave away at the screen for most of the day.
Your information should not come from one sole medium. Twitter is an incredible resource for OSINT work if you curate aggressively. There are also a lot of great mediums and sources that cover geopolitical/international affairs but don't publish in English. You shouldn't ignore these. If you're trying to trade events that pertain to non-Anglo governments, garnering OSINT from exclusively English-publishing sources and accounts also means that the information you're planning to trade off of is most likely already stale.
If you're trading war markets, Telegram channels are also great for keeping up to date on several conflicts. If your market of interest involves the US (it almost always does), look up the US embassy in that region and keep track of their appointment availability. If the US is considering to potentially launch a large scale military operation in some hostile state, one could theoretically call the embassy in that region and inquire about the next availability for an emergency passport appointment. If the appointment calendar on the embassy website says they're fully booked for the next two weeks, but when you call they tell you that you should come in same-day with minimal paperwork, it sometimes means something.
The whole point of all this is to streamline the flow of relevant information so you can react faster than the market. Once you can systemize your process of gathering information, the final part is maintaining neutrality. I've seen countless examples of amazing traders on Polymarket with phenomenal systems and proven track records who then throw out a large chunk of their PnL by trading emotionally. Politics and sports are the two surfaces where this behavior occurs most. It's fine if you want to trade the Superbowl or the US election, but make sure to keep your cool and avoid trading emotionally. If you're looking to donate your money, I'd recommend doing it with a charity and not a sharp.
Portfolio sizing is an incredibly misunderstood topic that you'll see many people give uninformed takes on. You might have seen a tweet about some whale punting big size into a market for a paltry gain, and the comments will be full of people calling it stupid. Its like they think the odds are 50/50, when in actuality the real odds are most likely smaller than the market implied one.
Nominal return is irrelevant. What matters is the differential between the market implied odds and your implied odds. Picking up $20 is rational if the probability of $1000 falling out your pocket is exceedingly small. Most people don't like to think in these terms though, because the chance of losing more than they can gain, despite however small that probability may be, is too daunting.
Generally speaking, I only entertained markets where my calculated odds differed from the market odds by a margin of 10% or larger. Anything smaller than that, I ignored. It's impossible to have a perfect understanding of these markets, especially when you're not an insider, and pretending otherwise is how you get cleaned out. So you have to include a margin of error to compensate.
Regarding differentials, the larger it is, the more ammo you should be firing into that market. This is Kelly 101. However, we don't run normal Kelly as it assumes we have perfect info. Since we don't, we still apply it but at a fractional value, like 1/4 or 1/5. So if raw Kelly tells you to bet 20% on a certain market, you're actually going to bet 4-5% of your bankroll. This ensures that you don't get turkey-ed on a miscalculated bet and that the law of large numbers eventually works to your favor. The number one thing is to always survive. Preserving ammo is critical. Burning your stack right before a clean opportunity appears is a terrible outcome.
Markets pertaining to individual people require a different approach, and its exigent that you do your homework on these personas. You have to know these people better than the market does.
Trump is the cleanest case study of this. People forget that he was in the showbiz for decades. He has a flair for drama and his statements are routinely over-weighted by markets that ignore his history of reversal and theatrics. Traditional markets call this TACO. And this same phenomena also exists in prediction markets: traders react to what the headlines say in bold and usually forget the underlying patterns. In simpler words, they miss the forest for the trees.
This is the framework I used to capitalize on these markets. If you're a trader who disagrees, I'm open to testing it.
I'm willing to match up to $1M USD for escrow and run a six-month, no-top-up comparison using public accounts funded with one-time $10,000 deposits. Largest ending balance wins. Collateral held in yield-bearing stables via escrow.
Terms are fixed. DM if interested.
