Does its posted price hold?
Of 572 bet105 prices Omenizer flagged as market-beating in the last 90 days, 54% were still there or better when we looked again; 46% had moved against the bettor and 0% had the market pulled. Measured only on prices we flagged as outliers — the ones most likely to be corrected — so read it against other books here, not as a share of bet105's whole board.

Who runs bet105

Availability: licensed in CA, CH, DE, ES, FR, GB, NO, PT; accessible from MX, US. (reported — verification in progress)

In the last 90 days, bet105 posted the board-leading price on 572 signals flagged by Omenizer's detection engine.

The margin is the bookmaker's built-in fee: the amount by which its implied probabilities exceed 100%. A 4.74% margin means that, on a typical bet105 market, prices pay out 4.74% less than a fair-value book would. Omenizer's fair prices remove this margin using sharp reference sources — the methodology explains how.

FAQ

Is bet105 legit?
Omenizer has not yet verified which company operates bet105 or what licence it holds — a gap in our research rather than a finding against the book. Independently of that, Omenizer has measured 8,117 bet105 markets in the last 7 days against the rest of the market, so its prices are observable rather than taken on trust. We publish the checks we can evidence and flag the ones we cannot — we do not certify bookmakers.
Who owns bet105?
Omenizer has not yet verified the company behind bet105. We record an operator only when we have read it on the operator's own site or a regulator's register, so this is an unfilled gap rather than a guess we declined to make.
Is bet105 licensed?
Not established — we have not confirmed a licence for bet105.
What is bet105's betting margin?
Measured across 8,117 markets in the last 7 days, bet105's median margin (overround) was 4.74% — rank #12 of 145 bookmakers Omenizer tracks. Lower is better for bettors.
How often does bet105 have the best odds?
Where at least five independent operators priced the same market (clone brands sharing one price feed count once), bet105 posted the single best price 10.7% of the time over the last 7 days.
How is bet105's margin measured?
Omenizer records every price on every tracked market, converts them to implied probabilities, and sums each market's sides; the amount over 100% is the bookmaker's margin. The figure here is the median across all of the book's observed markets — measured, not quoted from marketing material.
