Hi all,

There are so many idioms and expressions in English, and one that is often overlooked, yet used quite often in North America is I bet...”
(In the United Kingdom, its equivalent is "I reckon...")

'To bet' means to wager. 'To wager' means to put down money on a prediction that you made or on a probability of something happening. If your prediction comes true, you win money. If it doesn't come true, you lose the money you put up. Of course, this is used as an idiom, and idioms do not really mean what they say, so this is not how we usually use "I bet..."

As an idiom, when someone says, I bet...” it means they make a casual prediction about something.

We can use this for things we predict will or will not happen in the future:

I bet my favorite soccer team wins the game tonight.”

I bet she arrives late again! She is always late.”

We can use this for things we predict that are true in the present:

I bet mom has finished cooking dinner. Let's go to the kitchen.”

I bet you're tired. Let's go to bed.”

We can use this for things we predict did or didn't happen in the past:

I bet you didn't do your homework.”

I bet you forgot my name!”

We also use I bet! when we want to agree with someone in a sarcastic way. Notice the use of the exclamation mark to denote emotion. 

A: She only likes expensive gifts.
B: Yeah, I bet!

For this definition, we can use I bet! alone, or we can repeat the verb and pronoun in the original statement:

A: He wants more candy.
B: Yeah, I bet he does! (here, the stress is on 'does')

We also say, I bet!” when we do not believe someone and we want to disagree with them. It is said sarcastically in this situation.

A: I am a rich business owner. Let's go on a date.
B: Yeah, I bet! No way!

We also say, You bet!”

You bet!” is said as a cute, fun way of saying “Yes!” when someone asks for something.

A: Can I have another beer, please?
B: You bet!

We also say, You bet!” when someone understates a (perceived) fact (this means they state a fact casually) and we want them to say it more seriously. So, we confirm what they said very assertively.

For example,
A: You are very beautiful.
B: You bet I'm beautiful!

A: Ew! It's really hot outside!
B: You bet it's hot outside!

I bet you learned something new and I bet you will use "I bet..." in your next English conversation.

I bet you think I'm a smart teacher now.
