What Does the Kalshi Referral Code ACTION Do?
A $25 qualifying trade unlocks a randomized bonus ranging from $15 to $500 through the Kalshi referral code ACTION. Every qualifying trader collects at least $15, and a small slice lands the $500 headline figure.
That structure is what separates Kalshi from every other prediction market promo. Polymarket hands each new user a flat $20. Kalshi runs a lottery instead — a guaranteed floor of $15 with a live shot at something much bigger.
What Are My Actual Chances At $500 in Bonuses with Kalshi?
Kalshi publishes the odds for each tier in its promotional terms. Here they are:
| Bonus Tier | Chance |
|---|---|
| $15 Tier | 70% Chance |
| $35 Tier | 24% Chance |
| $75 Tier | 5% Chance |
| $100 Tier | 0.65% Chance |
| $500 Tier | 0.35% Chance |
Three takeaways worth your attention:
- $15 is the realistic expectation. Seven of every ten qualifying traders land exactly there.
- 94% finish at $15 or $35. The top three tiers combined account for 6% of users.
- The blended average sits near $25 — almost exactly the qualifying trade itself.
Nothing improves your draw. Trade size, market choice, and timing leave the odds untouched, so treat the $500 as a lottery ticket attached to a guaranteed $15 rather than the reason you sign up.
How Can I Use My Kalshi bonuses?
I entered the Kalshi promo code ACTION at signup, deposited the $10 minimum, and cleared $25 in trades. The qualifying trade's result never mattered; Kalshi will credit the bonus whether your first trade wins or loses.
My draw came back at $35. Two tiers exist below the headline and two above it, and I landed in the second-most common bucket.
Three things you need to remember, whatever bonuses you draw:
- Credits expire seven days after Kalshi grants them. That clock moves fast.
- A 1x trade-through applies. You can trade the $25 however you want, across one contract or multiple
- Credits cannot be withdrawn. Your bonuses must be traded on Kalshi; any payouts from these trades can be withdrawn as cash.

Titans vs. 49ers Preview
The whole market on this game is built on one sentence: Robert Saleh is playing his starters and Kyle Shanahan is not.
Saleh has always treated August as real football — he went 10-3 against the spread in preseason games with the Jets, a striking number next to his 20-36 record in games that counted. He confirmed this week that his full group will be out there, and pointedly noted it would be more than a single series. Shanahan, meanwhile, has said the opposite: most of his key players are getting the night off, with Christian McCaffrey already being managed through tightness and George Kittle still working back from an Achilles injury.
That information moved the number hard. This game opened with Tennessee as a 2.5-point favorite and has been bet up through -4.5 to -6 depending on where you look. There is also some genuine heat behind it — the two teams held joint practices this week that produced four separate fights inside ten minutes.
The subplot worth watching is Cam Ward. The 2025 No. 1 overall pick had a rough rookie year, completing 59.8% of his passes for 3,159 yards with 15 touchdowns and seven interceptions behind a line that surrendered 55 sacks. His second preseason is a chance to look like the player Tennessee drafted. The catch, for betting purposes: Ward has yet to throw a touchdown pass in three career preseason appearances, and he never attempted more than eight passes in a preseason game last August.
Titans vs. 49ers Prediction and Pick
The pick: San Francisco 49ers +3.5
We are taking the 49ers to cover, and the case is mostly about price rather than talent.
"Starters versus backups" is the most public angle in preseason betting, and it has already been paid for. A number that walked from -2.5 to nearly -6 on nothing but a coach's press conference is a number that has absorbed all of the available information and then some. Every dollar arriving now is buying the story at retail.
Then there is what actually happens on the field. Saleh's starters are not playing four quarters — they are playing a portion, and Ward's own preseason usage suggests a very short leash. Once both sidelines empty, this becomes a backup-versus-backup game decided in the second half, where a single fourth-quarter drive from a fringe roster quarterback swings a five-point spread. Shanahan has quietly navigated that chaos as well as anyone, sitting at 15-11-1 against the spread in the preseason.
The scoring profile supports the underdog too. Five of Tennessee's last seven preseason games have finished with 36 points or fewer, while four consecutive 49ers preseason games have cleared 39. If this stays in the 30s, Tennessee needs a two-score margin in a low-scoring game — a real ask against 49ers depth playing for jobs.
The number matters more than usual here. Our call was made at 49ers +3.5, and the market has since pushed past it. Every book below is now offering more than +3.5 on San Francisco, so anyone shopping properly is getting the pick at a better price than we graded it. That is free equity — take it.
