Infiniti Intelligence Hourly Briefing — Oct 9, 2026 · 2:54 PM ET

Funding ambitions rise

Kalshi and Polymarket are discussing fresh investment rounds that could value each company at about $20bn (£15bn), according to the Wall Street Journal, as relayed by EGR Intel in a report republished by GambleRss. Negotiations remain preliminary: neither privately held platform is assured of securing that valuation.

The proposed rounds would follow substantial investments toward the end of 2025. Kalshi raised $1bn in a December Series E at an $11bn valuation, led by Paradigm with participation from Sequoia Capital, Andreessen Horowitz, Meritech Capital and IVP. Less than two months earlier, it had raised $300m in a round that enabled expansion into more than 140 countries.

Polymarket, meanwhile, received a $2bn investment from Intercontinental Exchange (ICE) around the same period, valuing it at more than $8bn. According to EGR Intel, the platform has been unavailable in the US since 2022 and subsequently bought QCEX, which holds a Commodity Futures Trading Commission (CFTC) licence, to accelerate its return.

A contrast with listed betting operators

The fundraising ambitions come as publicly traded sports betting businesses face valuation pressure that EGR Intel linked to competition from prediction markets. Flutter’s shares have fallen more than 60% over the past six months, leaving a $19.7bn market capitalisation. DraftKings has declined 45.2% over that period, with its market value at $12.4bn. The proposed private-company valuations, however, remain negotiating targets rather than completed transactions.

Market conduct and regulatory challenges

Both platforms faced scrutiny earlier this month over contracts connected to US and Israeli strikes on Iran, according to EGR Intel. On Polymarket, six users collectively made $1.2m from a market asking whether the US would strike Iran by a specified deadline, raising concerns about insider trading. That market was created in December 2025; the reported concerns do not establish that insider trading occurred.

Kalshi drew criticism for declining to pay out trades on whether former Ayatollah Ali Khamenei would leave office by a specified date. CEO Tarek Mansour said on X that the platform would not pay out on markets involving death and instead refunded trades in the affected market, EGR Intel reported.

State-level opposition also remains a constraint. In January, a Massachusetts judge issued a temporary injunction preventing Kalshi from offering sports-related event contracts in the state without a gaming licence. In November, a Nevada judge overturned an earlier injunction that had kept Kalshi operating during a prolonged dispute with the state regulator, according to EGR Intel.

Regulators in Tennessee and Connecticut have issued cease-and-desist orders to prediction-market platforms, including Kalshi and Polymarket, in recent months. The Netherlands Gambling Authority also issued Polymarket a cease-and-desist order last month, EGR Intel reported.

What it means for prediction markets

• Funding is not yet secured. The roughly $20bn figures describe potential valuations under discussion, not agreed financing terms or completed rounds.
• Access remains a separate question. Higher valuations would not, by themselves, resolve state licensing disputes or Polymarket’s US return.
• Contract handling matters alongside growth. The Iran-related controversies highlight the importance of settlement rules and market-integrity safeguards for participants.
• Valuation comparisons need context. Flutter and DraftKings have quoted public-market values; Kalshi and Polymarket are pursuing valuations through private fundraising negotiations.

Hartnett flags election risk for stocks

Bank of America’s chief equity strategist, Hartnett, says a Democratic sweep could push stocks down 10% or more, according to MarketWatch. His warning frames the election outcome as a significant risk for equities.

The report, published Oct 9, 2026, at 2:54 PM ET, puts the probability of a Democratic sweep at 64% in betting markets. That is up from under 50% a month ago.

A conditional warning

The sweep scenario concerns Democratic control of Congress, according to MarketWatch. The rise to 64% places that outcome above even odds, but still leaves substantial uncertainty.

Hartnett’s warning is conditional: the potential stock decline is tied to a Democratic sweep, rather than presented as an unconditional market forecast. The available summary does not specify a stock benchmark, a timeframe for the potential decline or which betting markets supplied the probability.

What it means for prediction markets

• Election odds have shifted: The move from under 50% to 64% represents an increase of more than 14 percentage points in a month.
• The probabilities measure different things: The 64% figure concerns a Democratic sweep—not the likelihood of a stock decline of 10% or more.
• Contract details remain unavailable: Without the underlying market names or resolution terms, the reported probability cannot be mapped precisely to a particular prediction-market contract.
