Miles Carrington spent seven years grinding daily fantasy football before pivoting to legal sports betting when his state went live in 2021. He has personally tested parlay builders, walked through cashout flows, and tracked payout timelines at a dozen licensed US sportsbooks. On this site he breaks down parlay math, bonus fine print, and tax obligations so readers know exactly what they're wagering and why.

About This Site

My name is Miles Carrington, and I built Parlay in Betting: Everything You Need to Know because I got tired of guides that quoted odds without explaining where those numbers came from. Five years ago I was grinding season-long fantasy football; today I focus almost entirely on legal US sports betting, with a particular obsession for parlay math, sportsbook promos, and the fine print that catches bettors off guard at payout time.

How does Miles Carrington research parlay content?

Every page on this site starts with a live bet slip, not a press release. Before I write a word about a parlay tool or promotion, I open the sportsbook app, build a ticket, and record the exact odds the slip displays. When I cover payout math — like the roughly $264 profit a $100 two-leg −110 parlay returns — I verify that figure against a calculator and cross-check it against the operator's own bet slip before publishing.

I care especially about the numbers that matter to real bettors: house edge percentages, W-2G thresholds, and the fine-print wagering requirements buried in promo terms. A 5-leg parlay can carry a house edge above 25%; most guides skip that fact entirely. I don't.

What topics does this site cover?

The site is organized into four main areas. The basics section covers plain-English parlay definitions and how legs work. The odds section digs into how the vig compounds across every leg you add. The types section explains same-game parlays, teasers, and correlated combinations. And the tax section walks through W-2G reporting rules — because hitting a big parlay and owing 24% in federal withholding is a surprise nobody needs.

Legal status matters here too. As of mid-2026, roughly 32 states permit statewide online or mobile wagering, so I flag state availability whenever I discuss a specific operator or promotion. Must be 21+. Gambling problem? Call 1-800-GAMBLER.

Facts on this site — odds, payout amounts, bonus terms, tax thresholds — come from operator bet slips, regulator announcements, and published industry sources. I do not manufacture numbers. If a figure changes (bonus amounts and promo terms shift frequently), I update the page and note the revision date in the article.
