Two identical bets, two different books, and a result that does not match what most odds-comparison tools would predict. A bettor staked the same selections at the same time on 1Win and Vellarti across a two-week window in early 2026, logging pre-match prices, live prices, and every cash out offer that appeared. The headline finding: 1Win’s average odds came in roughly 2% lower, yet its cash out values ran about 5% higher. For anyone who trades in and out of positions rather than holding to settlement, that gap flips the usual “best price wins” logic on its head. This case study breaks down how the test was run, where each book actually won, and how to apply the result to your own staking plan.
How the 1Win vs Vellarti test was set up
The tester opened funded accounts at both books, completed verification at each, and deposited the same amount in the same currency so that stake sizing stayed identical across platforms. Every bet was logged with kickoff time, market, pre-match price, stake, and the timestamp of any cash out offer. The sample covered 60 bets across football, basketball, and tennis, split between pre-match singles and in-play entries.
Vellarti is a smaller operator with a leaner market tree, while 1Win runs a wider sportsbook with more granular pricing. That difference matters because it shapes how each book reacts to live momentum. A book with fewer markets tends to move prices in bigger steps, which can create either opportunity or slippage depending on which side of the trade you are on.
Both accounts used the same bankroll rules: flat 1% stakes, no parlays, no hedging across books. The point was to isolate the pricing and cash out behaviour, not to run a profit-maximising strategy. That control is what makes the 2% and 5% figures meaningful rather than noise.
What was measured and why
Three data points went into the log for every bet: the best available pre-match price, the live price at the moment a cash out offer appeared, and the cash out value itself expressed as a percentage of the original stake. Comparing cash out as a percentage rather than a raw number normalises for stake size and makes the two books directly comparable.
Odds margin was calculated against a sharp closing line from Pinnacle, which is a common way to strip out the bookmaker’s built-in edge and see who is actually pricing closer to the true probability. That benchmark is what revealed the 2% average gap.
Odds comparison: where Vellarti edged ahead
Across the 60-bet sample, Vellarti returned an average price about 2% higher than 1Win on the same selections. On a 2.00 shot, that is the difference between 2.00 and 1.96, which compounds fast over volume. The gap was widest on mainstream football markets like 1X2 and over/under goals, and narrowest on niche markets where Vellarti simply did not offer a line at all.
That pattern is typical of a smaller book trying to compete on headline prices in the markets casual bettors check first. Vellarti’s margins were tighter on the obvious bets, but its market coverage was thinner, so the 2% advantage only applied to a subset of the sample. On the 18 bets where Vellarti did not price the market, 1Win was the only option and the comparison collapsed to a single number.
For a pure pre-match bettor holding every position to settlement, that 2% edge is real and it adds up. Over a season of flat staking, a 2% price improvement on winning bets is often the difference between breaking even and turning a small profit. This is the part of the case study where Vellarti looks like the smarter choice.
Where 1Win’s pricing held up better
1Win’s advantage showed up in live markets and in the depth of its market tree. The sportsbook carried more in-play options per event, which meant more chances to find a price that had not yet adjusted to a goal, a red card, or a momentum shift. On the 22 in-play bets in the sample, 1Win offered a live price on every single one, while Vellarti was missing live pricing on 4 of them.
The bookmaker is licensed by Curaçao and runs a broad product stack that includes a casino alongside the sportsbook, which gives it the liquidity to keep live markets open longer. That matters for anyone who treats a bet as a position to be managed rather than a ticket to be filed away.
It is worth noting that 1Win competes directly with bet365, Pinnacle, and 1xBet on market depth, and that competitive pressure shows in how quickly its live prices refresh. Vellarti, by contrast, behaves more like a focused retail book: sharp on the popular stuff, thin everywhere else.
Cash out: the 5% gap that changed the verdict
Here is where the case study gets interesting. When a cash out offer appeared on the same bet at both books at roughly the same moment, 1Win’s offer averaged about 5% higher than Vellarti’s, measured as a percentage of stake returned. On a 100 unit stake, that is the difference between cashing out at 82 and cashing out at 87.
That gap is not random. Cash out pricing reflects how a book values the remaining risk in your position, and books with deeper live market data tend to price that risk more accurately. 1Win’s cash out engine appears to lean on its own live odds feed, which updates more frequently than Vellarti’s. The result is a cash out number that tracks the true probability of the bet more closely.
For a hold-to-settlement bettor, the 5% cash out advantage is irrelevant. For an in-play trader, it is the whole game. If you enter and exit positions multiple times per session, a 5% better exit price on every trade dwarfs a 2% worse entry price. That is the core finding of this comparison, and it is the opposite of what a simple odds screen would tell you.
Practical steps to exploit the difference
If you want to apply this to your own betting, the workflow is straightforward. The key is to treat entry price and exit price as separate decisions rather than optimising only for the number you see before kickoff.
- Price the entry at both books before you stake, and accept the 2% hit at 1Win only if you plan to manage the position in-play.
- Set a cash out trigger before the event starts, such as “exit if the offer hits 80% of stake,” so you are not making the decision under live pressure.
- Log every cash out offer with a timestamp for at least 20 bets, because the 5% gap is an average and individual offers swing much wider.
- Use 1Win’s live streaming and in-play market depth to time exits around momentum shifts rather than waiting for the offer to drift.
- Keep a separate pre-match-only bankroll at Vellarti if you want the 2% price edge on bets you never intend to trade.
One caveat: the 5% figure comes from offers that appeared at both books at comparable moments. On some bets, Vellarti simply did not generate a cash out offer at all, particularly on lower-liquidity markets. In those cases the comparison is not 5% in 1Win’s favour, it is 1Win offering an exit where Vellarti offered none.
Payment mechanics also affect the real-world value of a cash out. 1Win supports cryptocurrency payments and e-wallet methods, with a minimum deposit of 0.5 $ and a minimum withdrawal of 10 $. Fast withdrawal rails matter for in-play traders because capital tied up in a pending withdrawal cannot be redeployed. Vellarti’s processing times were slower in this test, which is a hidden cost on top of the cash out gap.
Beyond the sportsbook, 1Win provides cashback up to 30% on casino play and offers a welcome bonus of +500% on deposit, which changes the effective cost of the first few weeks of trading. Those figures are not directly comparable to Vellarti’s offers because the two books structure bonuses differently, but they do affect how quickly you can build a working bankroll.
The account setup itself is worth planning around. 1Win has mobile apps for Android and iOS, and the registration process is short, but verification still takes time on both platforms. Complete it before you place your first in-play bet, because a pending verification can block a withdrawal exactly when you want to move funds. 1Win also offers live chat and phone support, which is useful when a cash out offer fails to appear or a live market goes down mid-event. Customer service response time was faster on 1Win in this test, though Vellarti’s email support resolved issues correctly, just slower.
If your betting is mostly pre-match singles that you never touch again, the 2% price edge at Vellarti is the number that matters and the cash out gap is noise. If you trade in and out of positions, run 1Win as your primary book and use Vellarti selectively for the markets where its pre-match prices are genuinely better. Log your own cash out offers for a month before committing, because the 5% average hides a wide spread, and your specific markets and stake sizes will produce a different number. The honest takeaway from this case study is that “best odds” is only the right metric for one style of bettor, and the other style should be watching the exit price instead.
