The Quick Answer
A major-league hitter homers in about one game in eight, and gets two or more hits in about one game in five. Precisely: 11.90% and 21.69%.
Those are not estimates. They are realized settlement rates from 158,621 settled player-prop markets between June 15 and August 20, 2026. Nobody modeled anything. The markets settled, and we counted.

The Rates
These rungs are listed for essentially every starting hitter, so each rate describes a real and consistent population.
| Stat | line | hits this often | 95% confidence | markets |
|---|---|---|---|---|
| Hits | 1+ | 61.01% | 60.22 - 61.80% | 14,624 |
| Hits | 2+ | 21.69% | 21.03 - 22.36% | 14,634 |
| Hits | 3+ | 4.73% | 4.40 - 5.09% | 14,627 |
| Home Runs | 1+ | 11.90% | 11.39 - 12.44% | 14,651 |
| Home Runs | 2+ | 0.84% | 0.70 - 1.01% | 13,218 |
| Total Bases | 2+ | 35.43% | 34.66 - 36.21% | 14,634 |
| Total Bases | 3+ | 20.96% | 20.31 - 21.63% | 14,633 |
| Total Bases | 4+ | 14.67% | 14.10 - 15.25% | 14,627 |
| Total Bases | 5+ | 7.79% | 7.31 - 8.30% | 11,233 |
| RBI | 1+ | 29.08% | 28.25 - 29.92% | 11,332 |
| RBI | 2+ | 10.58% | 10.02 - 11.16% | 11,280 |
Read across a stat and the shape is the interesting part. Getting one hit is close to a coin flip. Getting three is a once-a-month event. A hitter drives in a run in fewer than a third of his games, and two in barely one in ten.
These are settlement rates from a two-month window of exchange data. The exchange retires older markets as it goes, so a later pull will differ slightly from these figures. That is a property of the source rather than a defect in the count, and it is why the window is named everywhere the numbers are.
⛔ The Deep Lines Do Not Mean What They Appear To Mean
This is the part that would be wrong in almost any other write-up of this data, so here it is with the reason attached.
| Stat | line | apparent rate | 95% confidence | markets |
|---|---|---|---|---|
| Home Runs | 3+ | 0.90% | 0.25 - 3.23% | 222 |
| Total Bases | 6+ | 5.67% | 4.88 - 6.58% | 2,856 |
| Total Bases | 7+ | 5.86% | 3.58 - 9.44% | 256 |
| Total Bases | 8+ | 4.88% | 1.35 - 16.14% | 41 |
| Hits | 4+ | 1.33% | 1.01 - 1.76% | 3,675 |
| RBI | 3+ | 6.21% | 5.25 - 7.33% | 2,078 |
Two rungs in that table read HIGHER than the rung directly below them, which is impossible on its face:
- Three home runs reads 0.90%, above two home runs at 0.84%. Hitting three cannot be more likely than hitting two.
- Seven total bases reads 5.86%, above six at 5.67%. The same contradiction, in a second stat.
And one rung that says nothing at all: 8+ total bases reads 4.88%, but on 41 markets, with a confidence interval running from 1.35% to 16.14%. That interval is wide enough to contain almost any answer, so it is not evidence of anything and is not used as any here. It appears in the table because dropping it would be the more misleading choice.
The explanation is the most useful idea in this whole dataset.** These are not nested slices of one population. The exchange only lists a deep line when the hitter is capable of reaching it. A 3+ home run market gets offered on Aaron Judge and Shohei Ohtani. It does not get offered on a light-hitting shortstop.
So every rung describes a different, pre-selected group of hitters, and the selection gets stronger the deeper the line goes. The rarity of the event and the quality of the player pull in opposite directions, and roughly cancel.
⇒ The decision to list a line carries as much information as the price on it. When you see a market that is only offered on certain players, the offer itself is telling you something before you look at a single number.
So do not use the deep rates as base rates. They answer "how often does a hitter who was judged capable of this do it", a different and much harder question than the one they appear to answer.
⭐ Markets That Trade Settle Differently From Markets That Don't
A second finding, and it is a warning for anyone computing rates from market data.
| Stat | line | all markets listed | markets that actually traded | gap |
|---|---|---|---|---|
| RBI | 1+ | 29.08% | 39.32% | +10.2 pts |
| RBI | 2+ | 10.58% | 23.92% | +13.3 pts |
| Total Bases | 5+ | 7.79% | 18.33% | +10.5 pts |
| Total Bases | 4+ | 14.67% | 25.39% | +10.7 pts |
| Hits | 3+ | 4.73% | 6.74% | +2.0 pts |
People trade the props that are going to hit. Every rung tested runs 2 to 13 percentage points hotter among markets that saw volume than across everything listed. Across the whole table, 158,621 markets were listed and 116,117 traded.
⚠️ Be careful what you take from that. It does not show that traders are profitable. A market that trades is one somebody had a view on, and a favorable matchup attracts both attention and results — the causation runs through the matchup, not through skill. What it does show is that the two populations are verifiably different.
⇒ If you compute a base rate from traded markets only, you will get a number that is too high by up to 13 points. That is the practical warning.
Where This Came From, And Why That Matters
This exists because a trading idea failed.
The belief going in was that people overpay for deep prop longshots — that a 3+ home run contract at a penny was expensive. It is not. Measured against a realized 0.90%, a 1.00¢ price is roughly fair, and the upper confidence bound of 3.23% sits far above the price outright. There was no edge there.
The trade died. The measurement is what survived it — and the measurement is worth more than the trade was, because these settlement records are the only place these numbers exist. Sportsbooks do not quote a 3+ home run line, so nothing settles it, so nobody counts it.
What This Cannot Tell You
- It Is One Midsummer Window, June 15 to August 20, 2026. Rates move with the ball, the weather and the era.
- It Is The Exchange's Listing Universe, not all of baseball. The main table covers essentially every starter. The deep lines do not, which is the whole point of the section above.
- It Is Not A Betting Edge, and it is not offered as one. The idea that produced it was tested and killed.
- It Is A Rate, Not A Prediction. Nothing here tells you what a specific hitter does tonight.

FAQ
How often does an MLB player hit a home run in a game? About one game in eight — 11.90% across 14,651 settled markets, with a 95% confidence interval of 11.39% to 12.44%.
How often does a batter get two or more hits? 21.69%, or roughly one game in five, across 14,634 settled markets.
How often does a hitter get three or more hits? 4.73% — about once a month for an everyday player.
How often does a player drive in a run? 29.08% for one or more RBI; 10.58% for two or more.
How often does a player hit three home runs in a game? The honest answer is that this data cannot tell you. The settled rate reads 0.90%, but those markets are only listed on hitters capable of it, so the rate describes a pre-selected group of sluggers rather than a typical player. See the section above on why that number is not what it looks like.
Where do these numbers come from? Settled markets on Kalshi, a CFTC-regulated exchange, between June 15 and August 20, 2026 - 160,660 markets pulled, 158,621 entering the table. Every figure is a realized settlement rate, not a model output. The exchange retires older markets as its feed rolls forward, so a later pull will differ slightly.
