If you’re involved in political advertising, you already know that timing is everything. The difference between an efficient media buy and a budget-draining mistake often comes down to understanding how Connected TV (CTV) rates behave across different phases of the election cycle. Whether you’re managing a Senate campaign, a ballot initiative, or a PAC war chest, the cost of reaching voters through CTV platforms can swing dramatically depending on where you are in the political calendar. This guide breaks down the five most critical rate spikes that political advertisers encounter — specifically the differences between primary and general election environments — and gives you the strategic insight you need to plan smarter, bid more effectively, and ultimately stretch every campaign dollar further.
Understanding CTV in Political Advertising
Connected TV has fundamentally changed the landscape of political media buying. Unlike traditional linear television, CTV allows campaigns to target voters with incredible precision — by geography, voter file data, issue interest, party affiliation, and even likelihood to vote. Platforms like Hulu, Peacock, Paramount+, and dozens of free ad-supported streaming TV (FAST) channels have become prime real estate for campaigns looking to reach persuadable voters in their living rooms.
But CTV operates in a programmatic auction environment, which means that when demand rises, prices rise with it. Political advertising creates enormous waves of demand in very concentrated windows of time. Understanding when those waves hit — and how high they surge — is the single most important factor in effective CTV political media planning.
The CPM (cost per thousand impressions) for political CTV can range from $15 during off-cycle periods to well over $65–$80 in peak general election windows in competitive battleground markets. That’s a 4x to 5x price swing. If you’re not planning for these spikes, you’re either going to overpay or find yourself completely priced out of inventory when you need it most.
Primary vs. General: Baseline Rate Differences in Political Advertising
Before diving into specific spikes, it’s important to understand the structural difference between primary and general election rate environments. These two phases of the election cycle create fundamentally different market conditions for CTV political advertisers.
Primary Election Rate Environment
Primary elections are typically more localized and involve fewer competing campaigns. Because the universe of voters being targeted is smaller (often just registered Democrats or Republicans), the overall demand for CTV inventory is lower during most of the primary season. This creates a window of relative affordability.
- Average CPMs during primaries: $18–$35 in most markets
- Competitive primaries (multiple well-funded candidates) can push CPMs toward $40–$50
- Targeting audience size is smaller, which limits scale but also reduces competition
- Issue-based and down-ballot primaries often see the lowest rates of the cycle
General Election Rate Environment
The general election is a different beast entirely. Every campaign — federal, state, local — is running simultaneously. Super PACs and outside groups layer on top of candidate spending. Issue advocacy groups activate their budgets. Non-political advertisers (automotive, retail, pharma) are also competing for the same inventory heading into Q4.
- Average CPMs during generals: $35–$65+ depending on market and timing
- Presidential election years create the most expensive CTV environments ever recorded
- Battleground state CPMs can exceed $80–$100 in the final two weeks
- Inventory constraints mean many campaigns are simply unable to buy what they need at any price
Understanding this baseline difference sets the stage for recognizing the five specific rate spike moments that every political media buyer needs to have mapped out before the cycle begins.
Rate Spike #1: Early Primary Announcement Surge
The first critical rate spike occurs when high-profile candidates announce their campaigns. This is often underestimated because it happens early — sometimes 12 to 18 months before Election Day — when many campaigns are still in planning mode.
What Causes This Spike?
When a major candidate enters a race, several things happen simultaneously in the CTV marketplace. The announcing candidate launches a major media buy. Opposition research groups activate. Competing campaigns respond defensively. News media coverage drives viewers to streaming platforms, further inflating the value of that inventory.
- CPMs in the announcing candidate’s home state can jump 15–25% within 48 hours of a major announcement
- National campaigns see spillover demand in key early-state markets like Iowa, New Hampshire, Nevada, and South Carolina
- The spike typically lasts 7–14 days before settling back to baseline
Strategic Takeaway
If you’re aware of upcoming announcements — especially in a crowded primary field — consider locking in forward commitments or private marketplace (PMP) deals before the news breaks. Programmatic open auction buying during an announcement surge is the most expensive way to reach voters at this stage.
Campaigns that use guaranteed deal structures with publishers ahead of announcement windows often save 20–30% compared to those buying on the open market during the surge period. – Innovative Political Advertising Strategies for 2024
Rate Spike #2: Debate Windows and Political Advertising Costs
Political debates are among the most watched live television events of any election cycle. They drive massive spikes in both linear TV viewership and streaming activity — and that elevated attention directly translates into higher political advertising costs on CTV platforms.
The Pre-Debate Buying Rush
In the days leading up to a major debate, campaigns and outside groups scramble to get messaging in front of voters while political awareness is at a peak. This creates a demand surge that typically begins 5–7 days before the debate and peaks the day before and day of the event.
- CPMs in debate-relevant markets rise 20–40% in the week surrounding major debates
- Presidential debate windows during the general election can see CPM spikes of 50–70% above baseline
- CTV platforms that carry debate live-streams or debate recap content see the steepest rate increases
Post-Debate Momentum Buys
Campaigns that feel they’ve won a debate often try to capitalize with an immediate surge in ad spending — sometimes within hours of the event ending. This post-debate momentum buy creates a secondary spike that can last 3–5 days.
The strategic challenge is that inventory has already been compressed by pre-debate buying, so post-debate programmatic buys often hit the market at inflated CPMs. The most sophisticated political media buyers pre-negotiate conditional inventory holds that can be activated or cancelled based on debate performance.

Rate Spike #3: Final 72 Hours Before Election Day
This is the most universally recognized rate spike in all of political media buying. The final 72 hours before any election — primary or general — represent the single most expensive CTV advertising window of the cycle.
Why the Final Sprint Is So Expensive
Every campaign with remaining budget pushes hard in the final days. GOTV (Get Out The Vote) messaging activates across every channel. Persuasion campaigns make their last appeals. Opposition ads run at maximum frequency. The result is a market where everyone is buying at the same time with no flexibility on timing.
- General election final 72 hours: CPMs can reach $70–$110 in competitive markets
- Primary election final 72 hours: CPMs typically rise to $45–$65 in contested races
- CTV inventory is often fully sold out in battleground states, leaving programmatic buyers with frequency-capped remnant inventory
- Even campaigns with large budgets may find they cannot spend their money effectively due to pure inventory scarcity
How to Navigate This Spike
The best protection against final-sprint rate spikes is early commitment. Many savvy political buyers structure their CTV plans so that 60–70% of their total impressions are committed months in advance through guaranteed deals, with only 30–40% reserved for real-time programmatic buying in the final stretch.
Another effective strategy is geographic diversification. Instead of concentrating all final-sprint budget in the most contested precincts, expand slightly to adjacent markets where rates haven’t been as severely inflated but where persuadable voters still exist.
Rate Spike #4: General Election Battleground Market Compression
Perhaps the most structurally damaging rate environment for political advertisers isn’t a single spike — it’s the sustained market compression that occurs in battleground states throughout the general election period, typically running from Labor Day through Election Day.
Understanding Market Compression
In presidential election years, a handful of states — Pennsylvania, Michigan, Wisconsin, Arizona, Nevada, Georgia, and North Carolina — become the primary focus of billions of dollars in political advertising. The CTV inventory within these markets simply cannot absorb this level of demand at normal pricing.
- Pennsylvania and Michigan see sustained CPMs of $55–$85 throughout the final 8 weeks of a presidential cycle
- Small and mid-sized markets within battleground states (Scranton, Lansing, Green Bay) experience greater percentage inflation than major metros because their total inventory pools are smaller
- Down-ballot campaigns in battleground states are effectively priced out of premium inventory by presidential and Senate-level spending
- Non-political advertisers reduce their CTV presence in these markets during election season, knowing they’re competing against politically motivated unlimited-spend advertisers
Strategies for Campaigns in Compressed Markets
For campaigns operating in battleground markets, a purely reactive programmatic approach is a recipe for budget waste. Instead, consider these approaches: – Political OTT: Issue Ads — 5 Essential Rules to Master
- Secure PMP and direct deals with major CTV publishers before the primary ends — locking in general election inventory at pre-compression rates
- Use voter file targeting through data clean rooms to focus on the highest-value persuadable voters, reducing the total impression volume needed
- Explore FAST channel inventory (Tubi, Pluto TV, The Roku Channel) which often remains more affordable than premium publisher inventory even during compression periods
- Layer in audio streaming and podcast advertising as a cost-efficient complement to CTV when video inventory is fully compressed
Rate Spike #5: Runoff and Special Election Demand Explosions
Runoff elections and special elections represent a unique and often underestimated rate spike category. These events are essentially full elections compressed into a fraction of the normal campaign timeline, and they create some of the most extreme CTV rate environments of any political cycle.
What Makes Runoffs and Special Elections So Expensive
The January 2021 Georgia Senate runoffs are the most extreme example in recent history. Two Senate races — both nationally significant — occurred simultaneously in a single state, with national money flooding into a geographically constrained CTV market. The result was a nearly complete breakdown of normal pricing structures.
- Georgia CTV CPMs during the January 2021 runoffs reportedly reached $120–$150+ in some inventory categories
- Special elections with national implications (open Senate seats, high-profile gubernatorial vacancies) routinely see CPM spikes of 200–400% above normal market rates
- The compressed timeline means there is no early-buy advantage — the window from announcement to election day can be as short as 6–8 weeks
- Both sides of the race activate simultaneously, doubling demand overnight with no ramp-up period
Planning for Runoff Scenarios
Campaigns in states with runoff systems (Georgia, Louisiana, California jungle primaries) should build contingency media plans before the primary. Having pre-negotiated relationships with CTV publishers and DSP partners means you can activate quickly without paying the full shock-price premium that reactive buyers face.
For outside groups and PACs, runoffs require dedicated reserve budgets that are held back specifically for this scenario — not absorbed into the general election plan. (Learn more about political advertising)
How to Plan Your Political CTV Strategy Around Rate Spikes
Now that you understand the five critical rate spikes, let’s talk about building a comprehensive strategy that minimizes their impact on your campaign’s media efficiency.
Build a Political CTV Rate Spike Calendar
Every campaign should have a media calendar that maps out all anticipated rate spike windows for their specific race and market. This calendar should include:
- Candidate announcement dates for major competitors
- All scheduled primary and general election debates
- Primary election date(s) and runoff triggers
- General election date and early voting window openings
- Known outside group activation windows (based on FEC filings and historical patterns)
Diversify Your Buying Methods
Relying entirely on programmatic open auction buying for a political CTV campaign is a high-risk strategy. A balanced buying approach should include:
- Guaranteed/reserved deals with premium publishers for high-priority windows (20–30% of budget)
- Private marketplace (PMP) deals with curated inventory packages (30–40% of budget)
- Programmatic guaranteed deals with major DSP partners (15–20% of budget)
- Open auction programmatic reserved for opportunistic buying during lower-demand periods (15–20% of budget)
Use Data to Optimize During High-CPM Periods
When you’re paying premium CPMs, the quality of your targeting has never mattered more. During rate spike windows, focus your remaining programmatic budget on the highest-intent, highest-value voter segments:
- Modeled persuadable voters from your voter file partner
- Low-propensity supporters who need GOTV motivation
- Specific issue-based audiences in swing precincts
- Lookalike audiences modeled from known supporters
The Future of Political Advertising on CTV
The trajectory of political advertising on CTV points toward even higher rates and more intense competition in future cycles. Several trends are accelerating this dynamic.
Growing CTV Viewership Among Key Voter Demographics
CTV is no longer a channel that skews young. Data from 2022 and 2024 cycle targeting studies show that voters 45–65 are now heavy CTV users, spending 3–4 hours per day on streaming platforms. This demographic is the core persuasion target for most campaigns, meaning CTV has become the premium channel — not a complement to broadcast.
Increasing Supply-Side Constraints
While streaming viewership grows, the growth of ad-supported inventory is not keeping pace. Premium publishers maintain strict ad load limits to preserve user experience. This structural supply constraint means that as political demand continues to grow, it will increasingly chase a limited and inelastic pool of quality inventory.
AI-Driven Programmatic Bidding
The rise of AI-powered bidding algorithms in DSPs means that rate spikes can happen faster and more severely than in previous cycles. When multiple AI bidders simultaneously identify high-value political inventory, CPMs can spike within minutes — not hours. Political media buyers need to implement bid cap and pacing controls that prevent their DSP from overpaying during algorithmic bidding wars.
Conclusion
Understanding and anticipating rate spikes in CTV political advertising is no longer optional — it’s a core competency for any serious political media buyer. The five spikes outlined in this article — announcement surges, debate windows, final-sprint pressure, battleground compression, and runoff explosions — each require a tailored strategic response.
The campaigns that win the CTV efficiency battle are those that plan ahead, diversify their buying methods, lock in inventory before demand spikes hit, and use precision targeting to maximize every dollar when CPMs are elevated. The difference between a well-planned CTV buy and a reactive one in a competitive general election market can easily represent 30–50% variance in effective media delivery — which translates directly into voter reach and ultimately, election outcomes.
Whether you’re a first-time local candidate or a seasoned presidential campaign veteran, building your CTV strategy around these five rate spike realities is the smartest investment you can make before the first ad ever serves. Political advertising on CTV is only going to get more competitive and more expensive — the buyers who understand the rate cycle will always have the advantage over those who don’t.
