Mega Millions $403 Million Tonight — What a Winner Keeps (and Why This Weekend Tops $1 Billion)

Jackpot figures are the official estimates checked the morning of Oct. 16, 2026, for tonight's ~11:00 p.m. ET Mega Millions drawing. Estimates can change before the draw as sales come in. The drawing has not taken place yet. Jackpot Dreaming is a personal project and is not affiliated with any lottery.

A billion-dollar weekend, starting tonight

Lottery weeks rarely line up like this. Mega Millions sits at $403 million for Friday night. Powerball is already advertised at $600 million for Saturday. Add the two headlines and you get roughly $1.003 billion in advertised prize money across one weekend — the framing Lottery Geeks used on Oct. 15.

That combined figure is marketing math, not a single prize. Nobody wins both with one ticket. Still, it's why lines may be longer this weekend. The prize that draws tonight is Mega Millions. Powerball is tomorrow's story.

Mega Millions has been rolling for a while. Lottery Geeks reports 23 drawings without a jackpot winner since a Florida ticket took an $803 million prize on June 28. We haven't independently verified that drought count against every official drawing report, so treat the "23 since June 28" detail as attributed to them unless your state lottery's history page says the same thing.

Cash vs. the billboard number

Mega Millions, like Powerball, posts two figures. The $403 million is the annuity: 30 graduated payments over 29 years. The $162.1 million is the cash option — one lump sum.

Cash is about 40% of the advertised annuity tonight. That gap isn't a casual "penalty"; it's the present cost of funding the payment schedule, and it moves with interest rates. Almost every big winner takes the cash. For the longer tradeoff, see our lump sum vs. annuity guide — same framework, even though that post used a Powerball example.

On the site's 7% growth illustration for this Mega Millions prize in California, the lump-sum path grows to roughly $778 million after 30 years, versus about $678 million on the annuity path. Illustration, not a forecast. Markets don't guarantee 7%.

What a sole cash winner actually keeps

All of the numbers below assume one winning ticket, cash option, single filer, prize as the only income, run through our calculator the morning of Oct. 16. Married filing jointly, shared tickets, other income, and deductions change the result.

Federal tax first

On $162.1 million cash, federal tax for a single filer lands at about $59,927,000. The lottery withholds 24% up front — $38,904,000 — so even in a no-tax state the first check is larger than the final take-home, and roughly $21,023,000 more federal tax is due when you file.

After federal tax alone, about $102,173,000 remains. Everything else is state (and sometimes city) tax coming out of that.

A handful of states, not a full ranking

We published a full 50-state Powerball table earlier this week. Tonight's post is narrower: the places people ask about most, plus the expensive end.

Same ticket. Same numbers. A New York City winner keeps about $24 million less than a Texan. California still exempts lottery prizes even though its ordinary income tax is high — that's why it sits with Florida and Texas on the top row.

If you take the annuity instead, the site's keep figures are $255,389,992 in a no-tax state, $245,314,992 in Arizona, and $198,285,444 in New York City. First annuity check after tax in a no-tax state is about $3,871,408; the last is about $15,779,438. Those are schedule estimates from the calculator, not a promise from Mega Millions.

Odds and what a $5 ticket is "worth"

Since the April 2025 redesign, Mega Millions jackpot odds are 1 in 290,472,336. A play costs $5, and the multiplier is built into non-jackpot prizes (it does not multiply the jackpot).

Our site expected-value math for a $5 ticket at this jackpot size comes out to about $1.67 back on average before tax — a −67% expected loss. That folds in lower-tier prizes and an adjustment for the chance the jackpot is shared. It is still a steep house edge. Treat a ticket as entertainment money you are fine spending, not as a half-investment that somehow "almost" pays for itself.

Powerball, for comparison on Saturday: jackpot odds 1 in 292,201,338, $2 per play. Saturday's cash option is $246 million. A California cash winner there would keep about $155,030,000; a New York City winner about $118,681,912, per the same calculator assumptions.

How to think about tonight without overthinking it

If you buy a ticket: use a licensed retailer, sign it, and ignore cold-call "you've already won" pitches. Big weekends bring scam waves.

If you somehow win: the address on your ID matters. Run your own state on the calculator before you celebrate the billboard number. Decide cash vs. annuity with a tax pro, not a group chat; our lump-sum guide is a starting point, not advice.

Skipping the ticket is also fine. A −67% expected loss is the lottery doing what lotteries do. The weekend's combined billion is a news headline, not a reason the math suddenly flipped.
