Kalshi’s tribal partnerships reach five

Kalshi’s expansion into tribal partnerships now encompasses five ventures, according to Gambling Insider. Four were announced on Oct. 7, following a partnership involving the Tunica-Biloxi Tribe’s SaltTrade Derivatives in September.

That sequence puts four of the five announcements on a single date. SaltTrade Derivatives is the only venture identified by name in the available summary.

The report, published Oct. 13, 2026, at 7:24 AM ET, describes the ventures as running on Kalshi’s infrastructure. The full source text was unavailable, limiting the detail that can be established about the arrangements.

The supplied material does not identify the four additional ventures or explain their commercial terms, product offerings or individual launch schedules. The central development is therefore the expanded partnership count, rather than a documented change in trading activity.

What it means for prediction markets

• A broader tribal footprint: Five partnerships indicate an expansion of Kalshi’s tribal relationships, with four ventures announced on Oct. 7 after September’s SaltTrade Derivatives partnership.
• Market impact remains unquantified: The available material provides no trading-volume, liquidity or participation figures, so the partnership count alone does not establish an effect on market activity.

VIP-bettor inquiry widens

Sen. Richard Blumenthal is expanding his scrutiny of VIP betting beyond FanDuel to DraftKings, Kalshi and Polymarket, according to bonus.com.

The development brings prediction-market platforms into an inquiry that had focused on VIP bettors at FanDuel. The available summary does not describe the specific questions directed at the additional companies.

The update, published Oct 13, 2026, at 7:24 AM ET, identified the expanded inquiry as the latest development and reported no significant new headline in the preceding 15 minutes.

The full bonus.com article was unavailable. The supplied material does not establish a response deadline, identify company responses or describe any resulting enforcement action.

What it means for prediction markets

• Kalshi and Polymarket are explicitly named. The scrutiny now extends beyond the previously identified FanDuel inquiry, according to bonus.com.
• An inquiry is not an outcome. The available information does not establish a finding of wrongdoing or a change in platform rules.
• Details remain important. The scope of any requests and subsequent official action would help readers assess the development against relevant contracts’ resolution criteria.

Finance prediction-market volume increased 143% to $57M, while economics climbed 113% to $4.8M, in the update published Oct 13, 2026 at 7:24 AM ET. Both categories grew faster than crypto, which gained 14% to $387M.

Finance accelerates as sports cools

The update describes sports activity as cooling but provides no sports volume or percentage change. That limits any comparison between the sports slowdown and gains in the other categories.

Crypto remained substantially larger than finance and economics by reported volume, despite its slower percentage growth. The figures therefore show a distinction between the fastest-growing categories and the largest of the three.

According to defirate.com, its volume reporting counts contracts at their $1 face value and separately lists $24.8B in dollars actually paid. The page also reports $3.2B in the last 24 hours. The supplied material does not specify the comparison period for the category growth rates.

What it means for prediction markets

• Growth and scale tell different stories: Finance’s 143% increase led the reported category gains, but crypto’s $387M volume remained larger.
• Measurement matters: Contract face value and dollars actually paid are distinct measures and should not be treated as interchangeable.
• The sports comparison is incomplete: Without sports figures or a stated category comparison period, the update does not establish how much activity shifted between sectors.
