The LiveTennis Slam Predictor is live. Pick the winners, lock the calls you trust, simulate the rest — then crown your champion and share your bracket. The interactive 128-player draw simulator launches with Wimbledon 2026 and rolls out to every Grand Slam after that. It is a play-along tool, not editorial coverage: for our actual draw analysis and predictions, follow the links further down.

What is the LiveTennis Slam Predictor?

The Slam Predictor is a free tennis bracket challenge that lets you build your own 128-player Grand Slam draw — every match, every round, all the way to the trophy. It is the easiest way to play along with the men’s and women’s singles draws at the big four: Wimbledon, the US Open, Roland-Garros and the Australian Open.

It works the same way every time. Click a player to pick the winner of a match. Drag the Upsets slider to set how chaotic you want the simulation to feel. Hit Simulate to fill the rest of the draw with the rankings, or build the bracket in stages — round by round — and decide the big calls yourself. When you have crowned a champion, copy the share link and the whole bracket travels with it.

How the draw predictor works

Click a player to pick the winner of a match — that pick locks in, and they advance round by round toward the trophy. Prefer to let the rankings decide? Hit Simulate full draw to auto-fill from the current seedings, or build it in stages: simulate only as far as the Round of 16, quarter-finals or semi-finals, then make the big calls yourself.

The Upsets slider sets how much chaos the simulation allows, from “Chalk” (seeds nearly always win) through “Realistic” to “Carnage” (anything goes). Lock the results you believe in and re-simulate everything else for a fresh run — your locked picks stay put. Change your mind on any match and the bracket re-flows from that point on. Once you have crowned a champion, copy the share link to send your finished bracket to friends — your whole prediction travels in the link.

What you can do with it

• Pick every match yourself, or simulate the full draw in one click
• Lock the calls you are sure of — Simulate only re-rolls the matches you have not locked
• Build it stage by stage: simulate up to the Round of 16, quarter-finals or semi-finals, then decide the rest
• Run a single quarter at a time, or the entire bracket
• Tune the upset level to model a chalky or chaotic fortnight
• Lock or unlock the whole bracket in one click, or reset and start again
• Crown your champion and see the projected finalists
• Share your completed bracket challenge with a single link

Lock your calls, then simulate the rest

Locking is the heart of the Slam Predictor. Most bracket simulators force you to choose: do the whole thing by hand, or auto-fill the lot. This one lets you do both at the same time. Lock the picks you would bet your house on — Sinner to make the final, your dark-horse quarter-finalist, a Briton through to the second week — and then keep hitting Simulate to roll the rest of the draw around them. Your locked picks never change; everything unlocked re-rolls fresh against the Upsets dial.

Combine it with staged simulation and you get a real “play the draw” experience: simulate up to the quarter-finals, study the eight lineups, lock the QF winners you fancy, simulate to the semi-finals, lock the finalists you back, then call the title yourself. Or start the other way — pin your champion from day one and watch the predictor build the road to the final around them.

Launching with Wimbledon 2026

The Slam Predictor goes live with Wimbledon 2026 — both the men’s singles draw (ATP) and the women’s singles draw (WTA). The full 128-player main draw is loaded — seeds, direct acceptances and qualifiers — so you can pick every match from the first round to the final, lock the calls you back and simulate the rest. Crown your champion, then share the whole bracket in one link.

Wimbledon is the launch event. The US Open, Roland-Garros and the Australian Open will all get their own Slam Predictor pages on the same schedule — illustrative seedings up first, then the real draw the moment it drops. Each Slam keeps the same lock-and-simulate flow, the same Upsets dial, and the same shareable champion card.

Frequently asked questions

What is the LiveTennis Slam Predictor?

It is a free interactive tennis bracket challenge that lets you predict the 128-player draw of any Grand Slam, lock the picks you believe in, simulate the rest, crown your champion and share the bracket. Launching with Wimbledon 2026, rolling out to all four Slams.

How does the Simulate button decide winners?

It weighs each player’s ranking and then applies the Upsets slider — higher settings give lower-ranked players a bigger chance of springing a surprise, just like a real Grand Slam fortnight. Simulate only fills the matches you have not locked, so you can pin your strong calls and re-roll the rest, or simulate just one stage or a single quarter at a time.

Can I lock my picks?

Yes — that is the point. Click a player to lock that match. Hit Simulate again and every unlocked match re-rolls fresh against the Upsets dial, while your locked picks stay exactly where you put them. Lock or unlock the whole bracket in one click from the controls.

Can I share my bracket?

Yes. Once you have crowned a champion, copy the share link and your entire bracket travels with it — anyone who opens the link sees your exact predictions and your finished champion card.

Is the Slam Predictor free?

Yes. The Slam Predictor is a free play-along tool. No sign-up, no account, no app — just open the page and pick your bracket.

Which tournaments will be supported?

Wimbledon 2026 is first up. The US Open, Roland-Garros and the Australian Open will follow, each on its own page with the same lock-and-simulate flow.
