Upside finds value for US sports bettors, picking out over 100 optimized bets every day across 30+ US sportsbooks and betting platforms. It has quick scanning times, expert filters to get exactly what you are after, and the data aggregator calculates EV+ and probability percentages, picking out the best betting lines for your next bets.
What makes Upside stand out is that it also has a bunch of exclusive features that we haven’t seen elsewhere. Through the eSports Discrepancy tool, fantasy props, +EV Sniper, and the Whale Watcher, it is designed to add valuable insights to your betting strategy and get you off to winning ways.

Upside Betting Features
Upside brings you EV+ bets, high-value player props, arbitrage wagers, eSports discrepancies, and whale watcher betting features, among more. You can use it to meet practically any ends, whether it is comparing parlay bets at the best US sportsbooks for value, or seeking the best-priced player props. The betting tool covers all the major US sports, including the NFL, NBA, NHL, MLB, and college sports. It also covers many of America’s other favorite sports to bet on, including tennis, soccer, golf, darts, UFC, and eSports.
The betting tool covers the odds at many top US sportsbooks, including the likes of DraftKings, FanDuel, BetMGM, and Caesars. It also has expert insights for DFS gaming, with coverage of major DFS platforms like PrizePicks, UnderDog, and ParlayPlay.. Upside also covers prediction markets and alternative betting platforms, including the likes of Kalshi and Polymarket, as well as Novig, Fliff, and various others.
Another is Epick Fantasy a prediction trading app that was created by the same team as Upside. Upside Tools is a tool that can be used in many applications, from squeezing out value from prediction markets to pairing arbitrage bets across sportsbooks and p2p betting apps, to optimizing your fantasy sports picks.

EV+ Optimizer and Props
Finding good value betting lines is all about scanning the market averages, calculating resulting probabilities, and spotting those outlier prices that give you a good margin against the averages. Speed is essential, as is broad coverage to get relevant and accurate results. We liked how Upside does all of this very efficiently. You can open the EV+ screen and scan through the highlighted EV+ bets and compare them. There are filters through which you can narrow down the results by different books, sports leagues, matches, date, and even the EV+ value.
On the right side of the display, you can shop lines at the different sportsbooks (and DFS/alternative betting platforms), and on the right, you get the EV percentage and the probability to win. You can filter by player props, and look for high-value NFL player bets, all kinds of NBA props, and player bets across any of the sports Upside covers. This is easy to use, and the odds continuously update in speeds of under 3 seconds, which is very powerful.
EV+ Sniper
Now what’s the difference between EV+ Optimizer (Silver package upwards) and the EV+ Sniper (Diamond)? Well, the EV+ Sniper reviews odds book-by-book, and has expandable rows that review the fair-value odds and give you more thorough breakdowns. It analyzes the book coverage, EV percentages and assesses closing line value, so you have a better idea of whether the line is worth hitting. It goes beyond the simpler EV+ optimizer that you get in the basic Odds Screen.
Arbitrage and Low Hold Finder
The strong scanner tech and the wide reach of sportsbooks and alternative betting platforms, like social sportsbooks, make Upside Tools ideal for arbitrage bets. Open the Arbitrage portal, and you can find high ROI hedged betting combinations, which you can filter by book and tweak to use your sportsbooks and work to your budget. The arbitrage bets also update continuously, which is an area that we have suffered with at other betting tools. At Upside, however, we found that the displayed lines and prices were always accurate, and the tool is quick to pick up any line changes.
The low hold tool is similarly precise. This hedging strategy is commonly associated with high rollers looking to gain access to the VIP program of a sportsbook. At Upside, however, there is a neat touch through the Target Bet Size filter, which allows lower budget bettors to also plan their road towards VIP tiers. You can compare odds at different books, change the recommendations to use your sportsbooks, and see how the ROI and hold % change by mixing and matching prices across any of the 30+ sportsbooks.

eSports Discrepancies
This is a fascinating and pretty unique feature at Upside Tools. The software scans for big discrepancies for eSports bets specifically. As it is a relatively niche sport, finding bets on these events can be difficult, but Upside can trace these to the DFS platforms that offer valuable eSports bets. And then, as a niche sport, there is a better chance for bigger discrepancies, thus opening higher EV+ and better arbitrage ROI.
The eSports discrepancies, or margins, can get very long at Upside, going beyond 10% and even up to 40% or higher. These are not just moneylines or spreads either, you can also get props such as CS2 headshot kills, or LoL map kills. There are also filters through which you can look at specific books, cover certain eSports, or just set a minimum threshold for the EV. We also like how Upside displays the number of results and the average market discrepancy % to give better context for these results.
Whale Watch
Whale Watching is something that is completely new to sports betting. The concept comes from stock trading or Forex trading, where you observe “whale” activity to determine the market sentiment. Whales here are the high rollers, and in trading, when a whale pumps or dumps a stock, it is commonly associated with a major market move. For sports betting, there are many parallels. For instance, when loads of money gets pumped into one side of a betting line, the odds on that bet tend to shrink, while the other side of the bet grows. It is a type of risk management that sportsbooks do.
Now, as a whale watcher, you track the spending activity on one line, and then you can anticipate future line movements. This is CLV betting done smart, and something that Upside does for you, so you can get in your bets before major line movements or sentiment shifts. You can also track winning whale movements and tail the big money that wins, just make sure to get in your prices while they are good, and before the sportsbooks shade their lines to cover their bases. We haven’t seen this software elsewhere, and it is one of the most intriguing and insightful features of Upside.

Betting Calculators
In the menu, you can open the Upside betting calculators, which can devig the odds, calculate the EV edges, match bonuses, calculate Kelly stake sizes, and also calculate the EV and probabilities of your parlay bets. These are simple, yet highly informative. You can use them to quickly calculate how much you should stake in your hedge bets, calculate fair percentages and vig on bet pairings, and much more.
We like how it is quick to pull these calculators up, and they don’t just cover the basics, but also crunch up EV, winning %, bonus conversion %, and other key numbers for your betting game.
Upside Tools Pricing Breakdown
Upside Tools has three subscription models, and while they are not cheap, we would consider them to fall somewhere among the “average-priced” tools. You aren’t paying hundreds of dollars per month, but you aren’t shelling out $10 for a month. That being said, they are fairly priced, and if you sign up for an annual subscription, you can knock off anywhere from 40% to 70% off the price (depending on the package).
Silver
$59.99/month
$359.99/year ($30 monthly)
The Silver Plan gives the full optimizer toolkit. You get +EV optimizers for props and game lines, the valuable arbitrage and low-hold finders, eSports discrepancies, and a live odds line shopping tool that features 30+ sportsbooks. You don’t, however, get the Whale Watch or EV+ Sniper feature.
Gold
$159.99/month
$799.99/year ($66.67 monthly)
Gold gives you the Whale Watch feature, and you also get a live sharp-money feed. Combine these two and you can track early line movements from the sharp sportsbooks, corroborate the data with any major whale moves, and it becomes the perfect combo for capitalizing on major odds changes. Gold also has a historical ROI tracker. Experts can use this, alongside the early line movement features, to learn from retrospective data to plan better ahead.
Diamond
$199.99/month
$999.99/year ($49.50 monthly)
The flagship subscription comes with everything in Gold, plus the +EV Sniper complete edge board. This doesn’t just give you the EV but also delves into book-by-book odds, the whys for the odds evaluation, and you also benefit from one-tap betslip generation. Diamond members also get access to the VIP Discord channel, where experts share exclusive plays and smart money moves, another very highly rated feature of Upside.
When you sign up through our links, you can get a 5-day free trial of any of the subscriptions, which gives you ample time to check out the coverage, test the EV+ bets, and get an idea of how Upside Tools can work for your betting workflow.

What Distinguishes Upside Tools
The whale watcher and Epick Trader features definitely give Upside a big boost over the competition. They are both well-thought-out tools that do something that your average CLV/line movement tracker or DFS optimizer doesn’t do. We also feel that the base Optimizer package is pretty competitive, with good US sports coverage, including niche sports, and it has good filters to help you navigate your way to the bets that best suit your strategy.
Areas to Improve
As it is right now, Upside is a highly efficient tool, and we feel it justifies its price tag. The only glaring omission is mobile apps, but the betting tool site is fully mobile accessible.
That being said, if there was anything we would like to see improved at Upside tools, it would probably be to have a more organized EV+ interface. If the main EV+ screen had filters for betting markets, it would enhance that user-friendly feeling and make it easier for members to filter directly for their preferred markets.
For the Optimizer subscription, we could argue that it would be useful to have line movement trackers, although not at the expense of pushing the price up. Another feature that would be very useful is a good bankroll management tool and ROI Tracker to help you analyze these edges and find out where Upside has worked best with your strategy.
Is Upside Tools Legit
Yes, Upside Tools is a trustworthy betting tool that we have trialed and tested. The tool is run by the same people who run Epick Fantasy, and there is a dedicated Discord channel, X page, and YouTube tutorials to help you get started. Diamond users also get a VIP Discord channel for exclusive plays and smart money metrics.
Who Upside Tools is For
Both DFS users and sports bettors can use Upside, and it has vast sports coverage, so you aren’t limited to betting on the main US sports leagues. Plus, Upside covers all the major US sportsbooks, so you aren’t getting irrelevant EV+ bets at blacklisted sites. There are insightful strategies and betting software that are simplified and made accessible for beginners. Take note, this is not a stats research tool, but a betting tool that analyzes betting odds and calculates the resulting EV, winning percentages, and picks out EV+ bets based on the odds offered.
Through the annual subscriptions, lower-budget bettors can also splash out on this premium tool and get an edge in their sports bets. The Whale Watcher function is very effective in the hands of a value bettor, and it can change the way you approach CLV betting and timing your wagers. The Epick Trader leans a little more towards DFS Pick’Em building. But, again, we feel it is also very useful for real money bettors who want to optimize their parlay betting.

Related Reviews
Upside Tools sets the bar high with its versatile suite of tools and confident approach to smarter betting. In this price category, you do have alternatives, each with its own specialist EV calculations, sports coverage, and associated betting strategies.
OddsShopper is a good all-rounder that has good EV tools, and another one is the sharp book EV formula used by Gambit Odds. If you are looking for a more arbitrage-first betting strategy, then BookieBeats has a strong offering, and for something a little cheaper but still going into advanced EV analytics, Nexus Odds is a good choice.
Our Verdict
For its originality, advanced scanners, and broad coverage (of both sports categories and sportsbooks), Upside gets a high rating in our review. We feel this tool can be used by virtually any bettor, and it has enough filters and features to optimize your sports bets. Having just 100+ EV bets per day is actually very realistic. Because Upside doesn’t scan international sportsbooks or unregulated books (where the outliers can be massive, but they are not accessible for US bettors).
So we felt pretty confident in the calculations, and enjoyed how efficiently Upside pinpoints good value in its betting markets. The tool is not as old as the likes of Outlier or OddsJam, but it is quickly building a name for itself, and it definitely has the software to compete with the more established betting tools in the US.
