Option Market Pricing Only 1% Move Ahead of Midterms

The US midterms are four weeks out, and the market doesn't seem to care.

I spent a long time this week pulling apart options data to find out what traders are pricing in for election night. The answer is not much. The options market expects the S&P 500 to move about 1% the day after the vote. That is the same move it expects from a routine Fed meeting.

That surprised me. The political environment feels more charged than it did going into the last midterms, yet the market is paying far less to protect itself. In the weeks before the 2022 vote, the VIX, Wall Street's fear gauge, sat in the mid-to-high 20s. Today it is near 15. Personally, I think options are cheap here, given how the last two midterms went and how much else lands in the same three weeks. Here is what I found, day by day.

How I Measured It

Options are contracts whose value depends on how far the market moves, and in which direction. The more movement traders expect, the more they cost, the same way flood insurance costs more in a flood zone. So option prices are a running vote on how much the market will move, and by when.

Options on the S&P 500 expire every trading day. The ones that expire on Election Day stop trading before any results are in. The ones that expire the next day live through the count. Each set of prices tells you how much total movement traders expect by that date. Whatever extra movement the day-after contracts build in, beyond what the Election Day contracts build in, belongs to the results. On Tuesday I measured that at about 81 points, or 1%. The market lands inside a move that size about two days out of three. The 0.8% figure you may have seen from the big banks is the same data measured with a slightly different yardstick.

Six Events in Two Weeks

I ran the same comparison for every day and got a calendar. Before Oct 26, traders expect an ordinary day to move about 0.7%. Then the expected moves step up.

Election week as a whole is priced for a 2.0% move. The Fed and earnings week before it, 1.96%. The week after, 1.95%. An ordinary October week, 1.5%. Traders have marked up three full weeks, with election night one bump among several.

What the Betting Markets Say

Kalshi lets people bet real money on election outcomes, and more than $30 million has been wagered on who controls Congress. As of Tuesday the odds were 65% that Democrats win both chambers, 28% that they win the House while Republicans keep the Senate, 8.6% that Republicans keep both, and 1% for the reverse split. Polymarket, the other big betting site, is within a couple of points on every line. Kalshi prices the no-change outcome, Republicans keeping both, at 8.6%. The three outcomes in which at least one chamber flips add up to about 94% at displayed prices. The two figures don't meet at 100 because each outcome trades as its own contract with its own spread. Either way, the market puts a flip somewhere above 90%.

That may help explain the quiet pricing. Options pay for surprise. When one broad outcome is better than a 90% favorite, there is less surprise left to pay for. What traders are still paying for is the Senate, which Kalshi puts at 63% Democratic, the size of the House margin, and the chance of a slow count. In 2022 it took more than a week to call the House.

The timing lines up too. The odds of a Democratic sweep sat near 50% through August and jumped above 60% in late September. Over the same weeks, the expected move for election night shrank. The two moved together over the same weeks, which fits the story without proving it.

Fear Is Cheap Right Now

Traders are paying a little more to protect against a drop than to bet on a rally. That is normal for the stock market, and the tilt is only slightly bigger than usual going into the vote. Overall, the cost of protecting a portfolio sits near the low end of the past year.

The VIX, often called Wall Street's fear gauge, is near 15, which is low. Bets on where it will be in late October and mid-November point to 17 or 18. That is the gauge's normal resting shape, with no spike around the election. The option prices put the odds of the fear gauge topping 20 by Oct 21 at under one in ten. The one sign of nerves: on Tuesday a lot of cheap VIX bets changed hands, the kind that only pay if something goes badly wrong.

What Happened the Last Five Times

• 2022: The S&P 500 fell 2.1% the day after the vote. Control of the House was still up in the air and a big inflation report was due the next morning.
• 2018: Up 2.1%, the best day after a midterm since 1982. Voters split Congress, as expected, and the market treated it as a relief.
• 2014: Up about 0.6%.
• 2010: Up about 0.4%, helped by a Fed stimulus announcement the same day.
• 2006: Up about 0.2%.

Two of the last five midterms moved the market twice as much as traders expect this time. The other three barely moved it. Average them and you land close to today's pricing. Options price a range of likely outcomes, not a prediction. The actual move can land well inside that range or blow through it, and the last five midterms did both.

The weeks before the vote have their own history. Cantor Fitzgerald counted 15 midterm years out of 24 since 1930 in which the S&P 500 dropped 5% or more during September and October. This year stocks are near a record and the fear gauge is near its lows. If history holds, the bigger risk is the run-up. Fear tends to build into the vote more than it spikes the night after.
