Chances are

Using this phrase is easier than picking a Netflix movie on a Friday night. Most of the time, you just drop it at the beginning of your sentence. The standard structure is Chances are (that) [something will happen]. You can include the word that, but most native speakers skip it because we are collectively in a hurry to get to the point. For example, Chances are he forgot his keys again. Notice how there is no is after Chances. It’s always are because chances is plural. If you say Chances is, a grammar fairy loses its wings. You can also use it at the end of a thought, like: "Will he show up? Chances are."

This phrase sits comfortably in the "Neutral to Informal" zone. It is perfect for chatting with friends, texting your group chat, or even sending a polite email to a coworker. You might hear it in a business meeting when someone is projecting sales: Chances are we'll hit our targets this quarter. However, you probably won't find it in a legal contract or a scientific paper. Lawyers and scientists hate being "pretty sure"—they want to be 100% sure or 0% sure. For your daily life—from Instagram captions to Zoom calls—it is a total winner. It makes you sound confident but not arrogant, which is the sweet spot of English social interaction.

Think about your daily digital life. You’re scrolling through TikTok and see a viral recipe. You might think, Chances are I’ll burn my kitchen down trying this. Or you’re waiting for an Uber in the rain. Chances are the driver is going to take the long way. In professional settings, it’s a lifesaver. If a client asks if a project will be done by Friday, saying Chances are we’ll be finished by then gives you a little "wiggle room" just in case your laptop decides to go on strike. It’s also used constantly in weather reports, sports commentary, and when guessing why your cat is staring at a blank wall at 3 AM.

Use Chances are when you have some evidence but aren't a prophet. Use it when you want to make a prediction based on a pattern. If your friend is always late, say Chances are she’s running ten minutes behind. It’s great for softening bad news too. Instead of saying "You won't get the job," a kind friend might say, Chances are they're looking for someone with more experience. It’s a way to be honest without being a total downer. It’s also the perfect phrase for when you’re about 70% to 90% certain of something. Any less than that, and you should probably stick to Maybe.

Don't use this when you are 100% certain. If you are standing in the middle of a lake, don't say Chances are I'm wet. You are definitely wet. Also, avoid it in extremely formal academic writing where It is highly probable or The likelihood is would be better suited. Never use it in a life-or-death situation either. If someone asks if the parachute will open, "Chances are it will" is not the answer they want to hear. That’s a one-way ticket to a very awkward silence (and a very fast descent).

One of the biggest traps is the "singular slip-up." Learners often say ✗ Chance is or ✗ The chance is. While grammatically possible in other contexts, as an expression, it must be Chances are. Another mistake is adding will incorrectly, like ✗ Chances are it will to rain. Remember, after Chances are, you just need a normal sentence: Chances are it will rain. Lastly, don't confuse it with By any chance. By any chance is for asking questions (Are you hungry, by any chance?), while Chances are is for making statements. Using the wrong one is like trying to use a fork to eat soup—technically possible, but very messy.

If you want to spice things up, you can say The chances are... which feels a bit more structured. In very casual slang, some people just say Odds are... which comes from the world of gambling. If you want to sound a bit more British, you might hear The likelihood is.... For something even more informal, try I bet.... But be careful with I bet, as it sounds much more like a personal opinion than a calculated guess. Chances are remains the gold standard for sounding balanced and smart without trying too hard.

Is Chances are the same as Maybe? Not quite. Maybe is 50/50. Chances are implies a much higher probability, usually based on some kind of logic or pattern. Can I use it for past events? Usually, no. It’s for predictions about the future or guesses about current unknown situations. If you're talking about the past, you'd say He probably forgot. Is it okay for text messages? Absolutely. It’s a very common way to respond quickly to a question when you aren't totally sure of the answer. Just remember to keep it plural!
