Election Arbitrage

A tale of two prediction markets

The gap in presidential election odds may have created an arbitrage opportunity in these new prediction markets.

A US federal appeals court ruled last week that Kalshi could list event contracts allowing Americans to bet on the US presidential election, and Kalshi wasted no time getting its new market live.

On Friday, October 4, the company launched its presidential election market, and Kalshi's founder and CEO Tarek Mansour noted that initial volume was so high that it caused issues with Kalshi's site.

Three days later, with the site now fully functioning, bettors have wagered approximately $773,000 on Kalshi's presidential market. However, the election market appears to have created an interesting arbitrage opportunity due to a gap between the election odds on Kalshi and competing prediction market platform Polymarket.

While Kalshi is currently pricing Harris at a 51% chance of winning...

Polymarket, which has gotten a great deal of media attention for its prediction markets, shows Trump leading Harris 53.7% to 45.6%.

It seems like there is a trade to make here: a trader could long Harris on Polymarket and short her on Kalshi, or long the underdog candidate in both markets. I'll be watching to see if these markets converge over time.

AMD posts top- and bottom-line beat in Q3 with Q4 sales guidance ahead of estimates

Advanced Micro Devices reported third-quarter results that exceeded analysts’ expectations on the top and bottom lines, with guidance to match.

  • Adjusted diluted earnings per share: $1.20 (compared to an analyst consensus estimate of $1.17)

  • Revenue: $9.25 billion (estimate: $8.74 billion, guidance: $8.4 billion to $9 billion)

  • Data center revenue: $4.34 billion (estimate: $4.14 billion)

  • Adjusted gross margin: 54% (estimate: 54%, guidance: 54%)

Its Q4 guidance for sales of $9.3 billion to $9.9 billion was strong relative to the anticipated $9.2 billion, while its adjusted gross margin outlook of 54.5% is bang in line with estimates.

Even so, shares are off about 2% in after-hours trading as of 4:24 p.m. ET.

“AMDs strong 3Q sales beat and 4Q outlook were likely driven by stronger PC and server CPU demand — similar to Intels results — along with continued share gains,” Bloomberg Intelligence analysts Kunjan Sobhani and Oscar Hernandez Tejada wrote. “The GPU ramp-up remains ahead of expectations, aided by a gaming rebound.”

AMD has had a high-profile Q4 so far, striking a megadeal with OpenAI that its CFO said “is expected to deliver tens of billions of dollars in revenue.” That announcement prompted more than 20 price target hikes from Wall Street analysts in a 24-hour span.

The company followed that up with a pact with Oracle, which said it would deploy 50,000 of AMD’s new flagship chips in data centers starting in the second half of next year. On the upcoming conference call, the Street will be looking for as much color as possible on the sales outlook for those MI450 chips.

Ahead of this release, Morgan Stanley analyst Joseph Moore wrote:

“The focus should remain on MI450. AMDs rack scale solution shipping next year is the key, and we are excited to see what the company can do. Its still early to make market share assessments, and while the Open AI agreement is clearly an accelerant, the reliance on cloud providers to ramp those 6 gigawatts still creates some uncertainty. Ultimately, to drive share gains, the company will need to provide better ROI than NVIDIA can offer, and customers still raise questions about that given lower rack density and the need to resolve ecosystem issues.

The chip designer was the third-best-performing member of the VanEck Semiconductor ETF in 2025 heading into this report, with shares having more than doubled year to date.
